An online experiment into the effects of masculine-themed versus neutral meat alternative marketing on men’s perceived association between meat and masculinity
Men often associate meat with masculinity, making meat reduction challenging. This study tested whether masculine-themed marketing messages (based on colors, fonts and wordings) for meat alternatives can influence men’s perceived association between meat and masculinity. In an online experiment (N = 231men, Mage = 35.64), participants viewed either “manly” or neutral ads for plant-based pizza and vegan nuggets. Perceived masculinity of meat (MoM) was measured before and after exposure. The New Masculinity Inventory (NMI) was included to assess openness to non-traditional masculinity. Results indicate that the condition was unrelated to perceived MoM. NMI was related to the perceived MoM, meaning that men who are more open to alternative forms of masculinity expressed a weaker association between meat and masculinity. This variable also functioned as a moderator, indicating that men in the neutral condition showed a stronger decrease in their perceived MoM compared to men who saw the manly advertisements.

An update on fermented plant-based dairy alternatives: Advances towards consumer acceptability and modern diets
Plant-based dairy alternatives (PBDA) represent a significant portion of the consumption of plant-based products, mainly to replace or complement the diet in relation to dairy milk, due to their health properties, the absence of lactose, environmental impacts, and consumer preference. These products have attracted a wide range of consumers, as they can be derived from different plant sources such as soy, rice, almonds, oats, cashews, and many others, offering different options for different needs and preferences. With the significant increase in the consumption of products that replace animal sources, other important concerns arise, mainly regarding the nutritional deficiency that each vegetable product offers, in addition to undesirable properties regarding adaptation to new foods. Fermentation technology is an attractive alternative as it can mitigate these sensory attributes that are present in plant-based products, as well as ensure greater food safety and health benefits of fermented products. Therefore, this review article will focus on the consumption of plant-based beverages as possible alternatives to dairy products. The consumer perception of PBDA will also be addressed, along with the differences between the fermentation of dairy milk and plant-based beverages, the challenges in the development of PBDA regarding rheological and sensory properties, and the health effects of the consumption of these fermented products.

Cross-cultural consumer acceptance of sustainable protein-rich foods; legumes, plant-based meat analogues and hybrids, and cell-based foods
As the world population continues to grow, adopting more sustainable eating behaviors becomes crucial to mitigating climate degradation. The study aimed to investigate Chinese (n = 672) and Danish (n = 272) consumers acceptance of sustainable protein-rich alternatives. This was done by presenting three categories of sustainable alternatives: legumes, plant-based meat analogues and hybrids, and cell-based foods in two identical online surveys. It was found that the Chinese participants held greater familiarity with the included food categories, more positive attitudes towards pro-environmental behaviors and higher consumption frequency of legumes and plant-based meat analogues and hybrids compared to the Danish. Both participants demonstrated the highest acceptance for legumes, followed by plant-based meat analogues and hybrids, and lastly, cell-based foods. Comparatively, cell-based foods seemed more promising for the Chinese participants while the Danish participants viewed plant-based meat analogues and hybrids more negatively on several aspects. Consumption scenarios were also evaluated for appropriateness across food categories, meal types, physical and social contexts, revealing distinct participant preferences. Legumes emerged as the more appropriate food choice for the participants. Generally, the Chinese participants showed more openness to sustainable protein-rich foods whereas the Danish remained more reluctant. The findings of this study provide valuable insights into cross-cultural differences in consumer perceptions of sustainable protein-rich foods and highlight the necessity for research focusing on a variety of drivers and barriers to consumption. It systematically investigated; legumes, plant-based meat analogues and hybrids, and cell-based foods, allowing for an in-depth comparison to be included in future research and policy developments.

Culinary applications and consumer acceptance
The increasing demand for meat alternatives is driven by environmental, health, and ethical concerns related to traditional meat production. As consumers become more aware of the impact of their dietary choices, options such as plant-based meats, cultured meats, and insect-based proteins have emerged as sustainable alternatives. This shift reflects a growing understanding of the environmental costs associated with animal agriculture and a desire for healthier food options. The history of meat consumption is linked to human evolution, with early hunting practices contributing to dietary advancements that facilitated physiological changes. At the same time, vegetarian and vegan diets, which were initially based on ethical and religious beliefs, have gained popularity in recent years due to concerns about animal welfare and sustainability. Consequently, the demand for meat substitutes, such as tofu, tempeh, seitan, and more recently, plant-based burgers, has surged. Advancements in food technology have led to the development of novel plant-based meats designed to closely mimic the sensory characteristics of animal-derived meats. Technologies like shear cell processing, 3D printing, and mycelium cultivation have improved the texture, flavor, and nutritional content of these substitutes. Products such as tofu, tempeh, and seitan are versatile and can be used in a variety of culinary applications, gaining mainstream acceptance. Insect-based proteins, known for their high nutritional value, are also being explored, although consumer acceptance remains a significant challenge due to cultural aversions and unfamiliarity. Cultured meat, produced by cultivating animal cells in bioreactors, has the potential to address ethical concerns by eliminating the need for traditional animal farming. Despite technological advancements, consumer acceptance of these novel proteins—including insect-based and cultured meats—remains an obstacle. Factors like sensory experience, familiarity, cultural influences, and health considerations shape consumer preferences. Transparent communication, improved sensory attributes, and affordability are essential for gaining broader acceptance of these sustainable alternatives.

Designing culturally acceptable, nutritious, and low environmental impact Finnish diets with mycoprotein: A novel optimization approach
Background
Meat alternatives can support a gradual reduction in meat consumption, contributing to more sustainable diets. Optimization is a useful tool to investigate this potential, but neglecting diet acceptability may limit the relevance of the approach.
Objectives
The aim of this study was to develop a new diet optimization model that includes meat alternatives and accounts for diet acceptability, then to apply it to characterize a culturally acceptable, nutritionally adequate, and low-climate impact Finnish diet that incorporates mycoprotein.
Methods
An original quadratic optimization model minimizing the weighted distance from the current diet was designed, with mycoprotein introduced as a new food within the meat group. The model first simulated a nutritionally adequate diet including mycoprotein (“NUTR” diet) and then progressively reduced dietary greenhouse gas emissions (GHGEs) while maintaining total consumption of the meat group. Model performance was assessed against a piecewise linear model, and robustness was tested through a sensitivity analysis.
Results
The meat group in the “NUTR” diet, which included 27.3 g (5.9 g) of mycoprotein, amounted to 82% (87%) of observed meat consumption for an average adult male (female). For further GHGE reductions, red and processed meats were replaced mainly by poultry, followed by mycoprotein with an increasing share. Imposing large reductions in GHGEs while maintaining meat consumption to its “NUTR” level led to larger adjustments in other food groups and raised potential nutritional concerns, whereas these issues were less pronounced for small to moderate GHGE reductions. Compared with the piecewise linear model, the quadratic formulation was less sensitive to baseline assumptions, yielding more robust and realistic diets.

Development of plant‐based milk alternatives and its future trends in the Middle East
The Middle East’s plant-based milk alternative (PBMA) market is projected to grow from $382.3 million in 2025 to $710.8 million by 2030, fueled by rising lactose intolerance (70% regional prevalence), environmental awareness, and religious dietary laws. Key drivers include halal certification demands (87% of Muslim consumers), kosher requirements in Jewish communities (prohibiting milk–meat mixing), and Eastern Orthodox Christian fasting traditions that periodically restrict dairy. Government initiatives like Saudi Arabia’s Vision 2030 and UAE’s 30% plant-based cafeteria mandate further accelerate adoption. The region leverages traditional ingredients like almonds, sesame, and dates through modern innovations: Saudi Arabia’s date-based milks, UAE’s shelf-stable technologies, and Qatar’s water-efficient aeroponic barley farming. Nutritionally, these alternatives address regional deficiencies—almond milk provides vitamin E, sesame milk offers bioavailable calcium/iron, and coconut milk delivers medium-chain triglycerides. Despite advantages, challenges include cultural dairy preferences, high costs (2× dairy prices in Saudi Arabia), and import dependence (90% of almonds). However, PBMAs show clear environmental benefits, using 90% less water and generating lower emissions than dairy. Future success depends on overcoming barriers through localized production, affordability improvements, and culturally adapted products that reconcile modern health trends with religious observance. The Middle East’s PBMA sector uniquely blends ancient food heritage with cutting-edge technology, positioning the region as a significant player in the global dairy alternatives market while addressing its distinct dietary, environmental, and religious landscape.

Disaggregated substitution patterns between plant‐based and animal meats: evidence from U.S. household purchases
A shift towards plant-based diets has appeared as a sustainable solution to the increasing carbon footprint. Despite a significant surge in popularity, the efficacy of plant-based meat alternatives (PBMAs) in achieving the stated goals of enhancing public health, environmental sustainability, and animal welfare through the displacement of animal-based meats (ABMs) remains inconclusive. Leveraging detailed, representative household scanner data from 2019 to 2021 for 136,553 households, this study provides a comprehensive analysis of consumer demand for PBMAs relative to ABMs. Unlike prior research that primarily relied on experimental methods or highly aggregated market-level data, this study investigates the extent to which consumers have shifted their protein choices from traditional ABM options to PBMAs based on 26 detailed product categories, thereby offering new insights into the full spectrum of consumer preferences for PBMAs et ABMs. We find that consumers allocate a marginal proportion of their meat budget to PBMAs and are more responsive to the price of PBMAs compared to ABMs, suggesting that price is still one of the major barriers impeding the protein transition. In addition, our analysis of substitution patterns indicates that, depending on the product category, PBMAs serve as both substitutes (e.g., plan-based beef patty) and complements (e.g., plant-based bacon) to their ABM counterparts. Combining results from market trends and demand relationships, the PBMAs have not yet looked promising in displacing ABMs in the short-term future.

Eco-anxiety, sustainable diet behaviours, and purchase intentions of meat alternatives among young adults in Malaysia
This study investigated eco-anxiety, sustainable diet behaviours (SDB), and purchase intentions for meat alternatives (PIMA) among young adults in Malaysia. An online questionnaire assessed socio-demographics, dietary habits, eco-anxiety (Hogg’s Scale), SDB (adapted instruments), and PIMA (Theory of Planned Behaviour-based scale) among 266 participants (71.4% female; median age 20 ± 3 years). Females reported higher affective symptoms (p = 0.040) and rumination (p = 0.028) than males, while non-science background participants scored higher for behavioural symptoms (p = 0.008). For SDB, females (p = 0.014) and middle-income participants (p = 0.042) had greater perceived effectiveness, though overall importance and behavioural control did not differ. Awareness of plant-based meat alternatives was high (84.2%) but lower for cultured meats (55.6%) and insect-based meats (30.8%); regular purchase was low, with 33.8% never buying plant-based and 81.2% never buying insect-based options. Correlation analysis showed that eco-anxiety was modestly associated with SDBs (up to r = 0.700), which in turn were moderately associated with PIMA (up to r = 0.628), while direct associations between eco-anxiety and purchase intentions were weaker (r = 0.246–0.348) but significant. In conclusion, eco-anxiety may drive SDB, yet adoption of novel protein sources requires interventions targeting affordability, skills, and familiarity.

Effects of sensory and environmental labelling of plant-based products on consumer acceptance: Context, energy density and framing factors
There is growing pressure to replace animal-sourced proteins with plant-based proteins. Consumer studies suggest sensory properties and environment are the major factors impacting adoption of PBFs, but few studies have contrasted these factors. Knowing that health labels negatively impact sensory experience, we tested whether environmental labels had the same negative impact. Using an online survey, volunteers (N = 328) were randomly assigned to one of three label contexts: sensory (emphasizing taste and texture), environmental (highlighting sustainability and environmental impact), or control (no specific messaging), where they evaluated eight plant-based alternative foods. Each product was enhanced by either a positive or a negatively valanced framing statement, with half the foods higher, and half lower, in energy density (ED). Participants rated expected liking, wanting and likely recommendation, and estimated what they would pay for each food. For liking and recommending, there was no significant difference between environmental and sensory contexts (p = 0.94), but both were significantly higher than control (p = 0.0006), while for expected wanting only the sensory exceeded the control (p = 0.0014). The amount willing to pay was significantly higher in the environmental than sensory (p = 0.0005) or control (p < 0.0001) contexts, which did not differ significantly (p = 0.49). For all four measures, higher ED foods were rated significantly more positively than lower ED (p < 0.001), while the effect of environment on purchase price was magnified by higher ED foods (p < 0.001). Positive framing statements were rated significantly higher than negative framing for liking (p < 0.001), wanting (p < 0.001) and recommending (p = 0.022), but not for purchase (p = 0.30). When habitual diet (plant-based or not) was included in the exploratory analyses, it only altered acceptance of lower energy-dense products in the control context. Overall, these data suggest that the use of environmental descriptors may enhance consumer expectations and willingness to pay more to the same degree as sensory descriptors, providing various strategies for marketers and product developers to promote PBFs based on messages that best fit the brand identity and expand the PBFs narrative beyond health.

Effects of the hedonic value of a starter dish on liking, emotional response, and intake of a plant-based main dish in an adolescent school setting
This study examined the impact of hedonic contrast on adolescents’ sensory and emotional responses, as well as intake, of an innovative plant-based main dish served in a real-life school canteen setting. A two-course Italian-style lunch was designed using either a bland or tasty variant of the same rice-and-vegetable starter, selected based on a preliminary study, followed by an innovative co-created plant-based dish, a lentil-pumpkin arancino. Across five weekly exposures, 128 students (aged 14–17) evaluated meal components using affective and emotional rating scales, alongside ad libitum intake measures according to a between-subject design (Meal with the tasty vs bland starter). Results from the initial exposure revealed no significant effect of starter condition on liking of the main dish. However, meals with the bland starter led to significantly higher intake and increased ratings of a high-arousal positive emotion (cheerfulness) toward the main dish, supporting a positive hedonic contrast effect on both behavior and emotional experience. With repeated exposures, a decline in liking and positive emotions was observed, particularly in the bland starter condition, suggesting a boredom effect. These findings indicate that emotional and intake responses to plant-based foods may be enhanced through hedonic contrast, even in the absence of increased liking, but also highlight the importance of menu variety to sustain positive effects over time. The findings offer practical insights for improving meal planning and support the introduction of healthy, sustainable, and innovative plant-based dishes in school foodservice contexts through the use of sensory and contextual strategies.

Environmental impact of meat substitutes
Meat production has a substantial negative influence on the environment, as livestock significantly contributes to resource depletion, greenhouse gas emissions, and ecological deterioration. This chapter explores how meat substitutes can help mitigate these issues and the effects that they have on the environment, nutrition, and society. Meat analogues, which include plant-based, fungi-based, and even cultured meat cell-based options, are an effective way of mitigating the adverse impact of conventional meat production on the environment. The research highlights the need for dietary transition in order to minimize the unsustainable trend of worldwide meat consumption, which fuels climate change, pressures on land use, and health risks like metabolic disorders. While plant-based foods have been shown to produce far fewer greenhouse gas emissions and use less land, water, and other resources than animal-based foods, there can be a wide variance in their environmental impact, depending on what ingredients or the processing methods used. The protein composition and bioavailability of plant-based meat substitutes (PBMAs) differ from those of animal products in terms of nutrition. PBMAs often include less fat and more fiber, but they may be deficient in important nutrients like methionine and have a lower iron bioavailability. This emphasizes how crucial it is to optimize formulations to guarantee enough nutrition. Effective marketing tactics, cost, and sensory replication are critical to PBMA consumer adoption, particularly in areas with deeply ingrained meat-consuming customs. An equitable transition to sustainable food systems, however, requires addressing regional differences and the socioeconomic functions of animals in low-income nations. Despite obstacles, PBMAs provide a valuable path for building resilient food systems while tackling environmental, nutritional, and financial issues.

Evolution, challenges, and way forward in the development of plant-based foods
The plant-based meat, egg, and dairy products have gained popularity among different consumer segments, particularly flexitarians, in the past decade. The value chain of plant-based foods encompasses the following stages: crop development, ingredient optimization, and end product composition and process optimization. Several innovations have already been accomplished across this value chain concerning process optimization and product development. Nevertheless, challenges and opportunities to address the same exist with respect to the diversification of plant-based ingredients, achieving taste and nutritional parity, and development of novel texturization techniques to obtain products with textures comparable to that of animal-derived products. Technology-based interventions to develop clean-label plant-based foods are another area of interest. This chapter will provide a comprehensive overview of the recent developments, challenges, and opportunities across the value chain of plant-based foods. It will begin with a description of the crop development approaches, followed by optimization strategies to achieve the desired functional properties of plant proteins for plant-based food applications. Novel sources of protein and ingredients for plant-based foods will be explained in detail. The latter sections will focus on process innovations such as extrusion, 3D printing, shear cell technology, and other novel techniques, supplemented by the product innovations that have emerged in the plant-based food sector. The last section will highlight the future scope for research in the area of plant-based foods, addressing sustainability, sensory, nutrition, and cost challenges in the development and consumer adoption of plant-based foods.

Exploring beef producers’ perceptions of cultivated beef: Challenges and opportunities
This study explores the perceptions of beef producers in the United States of America (USA) and France regarding cultivated beef, focusing on familiarity, perceived risks and opportunities, and prospects for collaboration with the cultivated beef industry. A structured online survey was conducted among 111 beef producers in the USA and 61 in France. Statistical analysis was used to identify differences in perception based on prior knowledge of the cultivated beef production process, and key socio-demographic and farm characteristics. Respondents from both countries had high awareness of cultivated beef, although beef producers in the USA were significantly more familiar (69.50%) as compared to beef producers in France (36.50%) with its production process. Most respondents in the USA did not perceive it as an environmentally friendly innovation, whereas French producers expressed mixed perceptions. Many respondents (36.70% in the USA and 67.30% in France) were uncertain about the possibility of collaboration with the cultivated meat industry. Producers with prior knowledge of the cultivated beef production process had a more favourable perception of its environmental benefits (mean rank: 75.36 vs. 54.47; p < 0.001) and zoonotic risks reduction (mean rank: 72.09 vs. 57.58; p = 0.012). Regression analyses further revealed that farming experience and management type significantly influenced producer attitudes toward cultivated beef’s perceived innovation, environmental value, and collaboration potential. This study highlights potential avenues for future research, including collaborative business models, co-regulatory frameworks, and policies to support coexistence between conventional and emerging protein sectors.

Exploring Italian consumers’ perceptions of cultivated meat: Barriers, drivers, and future prospects
Background/Objectives: The increasing global population and rising demand for protein-rich foods present significant challenges for the agri-food system. Cultivated meat, produced through cellular agriculture, is emerging as a promising alternative to traditional livestock farming, offering potential environmental and ethical benefits. However, its adoption remains controversial due to concerns about sustainability, safety, and cultural acceptance. This study investigates Italian consumers’ perceptions, knowledge, and willingness to purchase cultivated meat, considering psychological, demographic, and social factors. Methods: A structured online survey was conducted involving 437 Italian meat consumers, integrating established psychometric scales to assess key attitudes. Logistic regression analysis was applied to identify determinants of consumer acceptance. Results: Findings reveal that while awareness of cultivated meat is relatively high (81.92%), willingness to purchase it is low, at just 35.47%. The main motivations for interest are environmental sustainability (54.61%) and innovation appeal (25.00%), while the primary barriers are health concerns (31.58%) and doubts about production processes (34.59%). The results also show that food neophobia, environmental awareness, and inclination toward food innovation significantly influence purchasing decisions. Additionally, demographic factors, such as age, gender, income, and household size, play a crucial role. Conclusions: This study provides insights into consumer behavior toward food innovations, informing policymakers and industry stakeholders on strategies to enhance acceptance and promote sustainable food alternatives.

Exploring protein-based fishmeal alternatives for aquaculture feeds in Bangladesh
The rapid expansion of aquaculture in Bangladesh has played a vital role in meeting the increasing demand for fish protein. However, the industry faces significant challenges due to the high cost and environmental impact of fishmeal (FM), a primary protein source in aquafeeds. This review critically evaluates alternative protein sources for aquafeeds, including plant-based proteins, insect meals, agricultural by-products, and single-cell protein (SCP), with a focus on their applicability in the Bangladesh context. Using the Joanna Briggs Institute (JBI) methodology, we synthesized evidence from peer-reviewed studies and institutional reports to assess the nutritional profiles of these alternatives. Results show that while plant-based proteins are affordable and locally available, they require processing to reduce antinutritional factors (ANFs). Insect meals exhibit high protein content and feed efficiency, with a primary focus on their essential amino acids (EAAs) profiles, which are crucial for optimal fish growth, immunity, and metabolic performance. Agricultural wastes such as fruit peels and vegetable residues offer cost-effective and immune-boosting properties, while SCP derived from algae, fungi, yeast, and bacteria emerge as a nutritionally robust and environmentally sustainable option. Despite the promise of these alternatives, limitations persist in terms of nutrient imbalances, processing requirements, and scalability. Overcoming these barriers demands targeted research and development, policy support, and investment in local feed innovation to ensure sustainable aquaculture growth. This study underscores the critical need for further research and strategic implementation of alternative feed resources to enhance the sustainability, profitability, and resilience of aquaculture in Bangladesh, with a focus on optimizing inclusion levels, improving digestibility, and utilizing locally available ingredients to ensure nutritional balance and food security.

Food of the future? A review on the environmental impacts and sustainability of cultured meat
The growing global population and unsustainable consumption of natural resources are expected to exacerbate future food security challenges. Cultivated meat, a novel technology produced by culturing animal cells in controlled environments without the need for conventional livestock farming, offers a sustainable alternative that also supports animal welfare. This study presents a literature review focused on the environmental impacts of cultivated meat production, specifically analyzing studies utilizing the Life Cycle Assessment (LCA) methodology. In addition, the review considers health and safety implications, animal welfare concerns, and the economic landscape of the cultivated meat sector. Findings suggest that cultivated meat can be a sustainable solution, particularly when renewable energy sources are employed. However, energy consumption remains the primary contributor to environmental impact, with greenhouse gas emissions largely associated with energy use and culture media. The implications of large-scale production are still uncertain. While cultivated meat may benefit animal welfare, its long-term health effects are not yet fully understood. Despite a decline in investment in 2023, new market entrants and decreasing production costs reflect ongoing industry momentum. Overall, cultivated meat demonstrates strong potential as a sustainable protein source, though further research and technological development are necessary to realize its full promise.

Future foods: Global trends, opportunities, and sustainability challenges
The advent of plant-based foods, often referred to as “Future Foods,” represents a transformative approach to addressing the health, environmental, and ethical challenges associated with conventional diets. This chapter examines the development of diverse plant-based food categories, including dairy alternatives, fermented products, meat and seafood analogs derived from soy, pea proteins, and algae, and functional foods enriched with bioactive compounds from millets, pseudo-cereals, and legumes. It highlights the nutritional benefits of plant-based foods, emphasizing bioactive compounds and health-promoting properties while addressing challenges such as anti-nutritional factors and bioavailability. Technological advancements, including extraction, encapsulation, fermentation, drying, extrusion, and non-thermal techniques such as ultrasound, pulsed electric fields, and high-pressure processing, are critically analyzed for their mechanisms and effectiveness in enhancing food quality and retaining nutritional properties. Emerging technologies like 3D printing and artificial intelligence/machine learning are discussed for their potential to revolutionize plant-based food production. This comprehensive review underscores the role of plant-based foods in advancing global health and sustainability objectives, presenting them as a cornerstone for resilient and future-ready food systems.

Future protein foods: Plant versus animal sources, nutrient release rates, and gateway products
Achieving a sustainable balance of animal, plant, and alternative protein sources is complex and will continue to evolve with technological innovation.
The nutritional benefits of protein foods depend not only on composition but also on nutrient release rates—an area where some animal-sourced foods retain advantages over current alternatives.
Plant-based analogues of animal foods should serve as “gateway” products, guiding consumers toward the culinary richness, sustainability, and nutritional value of whole legume foods.

Hybrid alternative protein-based foods: Designing a healthier and more sustainable food supply
The industrial scale use of animals to produce food for humans, such as meat, egg, and dairy products, has serious environmental, health, and ethical implications. Livestock production is a major source of greenhouse gas emissions and drives soil depletion, water pollution, deforestation, and biodiversity loss. There are also concerns about its negative impacts on human health and animal welfare. To feed future generations, it will be important to produce nutritious foods in a more sustainable, ethical, and environmentally friendly manner. In this article, we examine several protein-rich food sources as alternatives to traditional animal proteins, including plants, insects, mycelia, cultured animal cells, and microbial fermentation products. Each of these alternative protein sources has advantages and disadvantages in terms of their organoleptic properties, nutritional profile, consumer acceptance, affordability, and scalability. We then consider combining different alternative protein sources to form affordable, scalable, delicious, nutritious, and sustainable hybrid foods that may compete with conventional meat products, including meat–plant, cultivated meat–plant, mycelium–plant, and insect–plant foods. However, these hybrid products are still relatively new, and significant challenges, including cost reduction, scalability, regulatory approval, and consumer acceptance, need to be addressed before they become commercially viable. Future research should therefore focus on optimizing protein sources, developing scalable production methods, conducting environmental and economic analyses, and leveraging artificial intelligence for innovation. To make hybrid food products viable and sustainable, more efficient collaboration across academia, industry, and regulatory bodies is urgently needed.

Influence of eating environment and protein context in a meal on consumer perceptions, acceptance and expected consumption of alternative proteins: An online study
Consumer acceptance of alternative proteins (APs) remains low, requiring efforts to identify ways to encourage shifts in consumer perceptions and behaviors towards APs. We investigated how meal contextual factors such as evoked protein context and eating environment, independently and in combination, influenced consumer perceptions, acceptance and expected consumption of APs in Singapore, and whether associations varied across consumer segments. Participants (N = 822) were pre-grouped into omnivores (n = 381) and flexitarians (n = 441) in an online study. Participants rated the perceived healthiness, naturalness, expected liking and consumption of a ‘chicken-noodles’ dish presented with three protein contexts (animal-based, plant-based, or an animal/plant hybrid) in four eating environments (home, hawker centre, urban restaurant, and nature restaurant). Results showed that independently, protein context influenced expected liking and consumption (both, p < 0.001) whereas environment influenced perceived healthiness and naturalness (both, p < 0.001) in all consumers. Omnivores rated liking and consumption as higher for the hybrid vs. plant-based meal, highlighting the potential of hybrid protein sources to facilitate the transition towards APs. Participants’ expected consumption was highest at home (p < 0.001). No combined effect was observed (p > 0.05). Our findings suggest meal context could be modified to shift consumer acceptance and consumption towards APs and aid public health guidance in promoting meat-reduced diets.

Italian consumers and cultured meat: Risk, preferences, and politics
Cultured meat is produced in vitro, and it is presented as a method able to reduce the controversial effect of farmed meat, on the environment and animal welfare. To speed up the shift to sustainable food systems with such innovation, it is necessary to analyze consumer preferences and attitudes towards this novel food. Attention should be paid specifically to the relevant role of consumers’ political affiliation, risk attitudes, and perceptions of cultured meat, as compared to farmed meat, on consumers’ acceptance of this novel food. This study investigates these aspects using a representative sample of the Italian population in terms of gender, age, and region, and a balance across education levels. Data collection was conducted via a digital platform in December 2023. The sample included 800 participants. The data were analyzed using an ordered logistic regression model, with marginal effects reported for clarity. Results show that as the level of acceptance increases, consumers’ preferences depend heavily on their’ perceptions of cultured meat as compared to farmed meat. Our research offers valuable insights into consumers’ views related to cultured meat. Additionally, it provides practical guidance to promote cultured meat using an evidence-based strategy.

Innovations, challenges, and regulatory pathways in cultured meat for a sustainable future
Cultured meat is produced through cellular agriculture and tissue engineering and has emerged as a promising alternative to conventional animal-based meat production. Cultured meat, produced through cellular agriculture and tissue engineering, offers a sustainable alternative to conventional meat production. This review outlines the potential of diverse stem cell sources, including satellite cells, embryonic stem cells, and induced pluripotent stem cells, for producing muscle and adipose tissue. Advances in bioprocess development, biomaterials, and bioreactor design are discussed, with an emphasis on scalability, cost reduction, and regulatory considerations. Despite progress, key challenges remain: replicating the nutritional composition and sensory qualities of conventional meat, developing serum-free media, and ensuring consistent large-scale production. Recent studies report cost reductions of up to 90% in culture media and successful bioreactor expansions beyond 50 L, yet industrial translation is still limited. Consumer acceptance and clear regulatory frameworks are also critical for commercialization. Future work should focus on integrating cellular innovations with scalable technologies to overcome current bottlenecks and accelerate market readiness.

Lab-grown meat: Understanding its science, market potential, and future outlook
Lab-grown meat, also known as cultured or cell-based meat, is an emerging innovation in food production that seeks to address the environmental, ethical, and health challenges associated with conventional livestock farming. Produced by cultivating animal stem cells in controlled bioreactor environments, this technology allows the development of muscle, fat, and connective tissues without the need for large-scale animal rearing and slaughter. The potential benefits include reduced animal suffering, lower risks of foodborne contamination, and improved resource efficiency in terms of land and water use. However, critical challenges remain, such as reliance on animal-derived culture media in early production stages, high energy demands, scalability limitations, and regulatory uncertainties, particularly in regions like the European Union. While lab-grown meat demonstrates promise as a sustainable alternative protein source, its future depends on overcoming technical barriers, ensuring environmental viability, and achieving consumer and regulatory acceptance.

Meat, without meat: A TPB and VBN integration to understand intention to consume new generation of plant-based meat alternatives
Purpose
New generation of plant-based meat alternatives (PBMAs) offers a sustainable alternative for mitigating the environmental strain associated with conventional meat production by offering a substitute that mimics the sensory properties of meat itself. However, the success of a novel food depends on consumer acceptance. Psychosocial literature has already shown that the theory of planned behaviour (TPB) and the value-belief-norm (VBN) model are solid frameworks for understanding and predicting healthy and sustainable food choices.
Design/methodology/approach
This study tests the integration of TPB and VBN with green self-identity and food neophobia to understand the intention to consume PBMAs. To this end, 317 Italian consumers (Mean age = 20.70) completed a self-report questionnaire to assess the variables studied.
Findings
Structural equation modelling revealed that attitude, subjective norms, perceived behavioural control and moral norms, significantly predict intention. Notably, subjective norms influenced moral norms, and green self-identity positively affected attitude, while food neophobia negatively impacted intention. The data indicate that simply raising awareness or informing individuals may not promote lasting behavioural changes, especially for novel foods such as PBMAs. On the contrary, strategies based on social influence and leveraging moral obligations towards the environment could be particularly effective.
Research limitations/implications
First and foremost, given the gap between the intention to engage in a certain behaviour and the actual acting out of the behaviour itself, the lack of a behaviour measurement is to be acknowledged as the most pressing limitation of the study. The study has limitations due to its sample, which is not representative of the Italian population because it is skewed towards women and younger adults. Additionally, the study did not consider other factors that could influence the intention to consume PBMAs, such as trust in producers, meat attachment, and political orientation.
Practical implications
This study has practical implications for promoting PBMAs. The findings suggest that strategies focused on social influence and moral obligations could be effective in encouraging PBMAs consumption. Educational campaigns and workshops could highlight the ethical and environmental benefits of PBMAs while emphasizing social norms and expectations. Additionally, addressing food neophobia through strategies such as exposure and information provision may be necessary to increase acceptance of these novel foods.
Social implications
Findings suggest that social influence can shape individuals’ moral perceptions about what is considered right or wrong in the context of food consumption. This highlights the interplay between social and moral factors in driving sustainable food choices. It is recommended that stakeholders take this into account by conducting educational campaigns or workshops that not only explain the ethical reasons for consuming plant-based alternatives but also emphasize how this aligns with societal trends and expectations (as for example, partnering with prominent community figures who advocate for PBMAs consumption for ethical reasons).
Originality/value
The study highlights the significant role of normative influences (subjective and moral norms) in predicting the intention to consume PBMAs, a novel contribution that can inform interventions aimed at leveraging social influence to encourage the adoption of more sustainable diets.

Nutritional composition and health implication of meat substitutes
Plant-based meat analogues (PBMAs) aim to replicate traditional meat. In doing so, they offer promising opportunities for improved sustainability, human health, and animal welfare. PBMAs are made using plant-based non-animal products, alongside plant protein, and cutting-edge technologies like extrusion and 3D printing are employed to achieve similarities with meat in terms of texture, taste, and look. They are fiber-rich but lower in saturated fat and cholesterol than regular meat, although several challenges exist in achieving the meat substitute’s desired micronutrient and protein bioavailability. The use of PBMAs has increased worldwide, owing to changing dietary paradigms of the masses, driven by ethical, environmental, and socio-economic factors. Research indicates that these substitutes would help reduce the risk of cardiovascular diseases and body mass index while lowering greenhouse gases. PBMAs possess certain undesirable characteristics, such as affecting the rate of their absorption and processing concerns. Fortification, as well as enhanced formulations containing more vitamins, is essential, especially with regards to Vitamin B12 and Zinc, as these vitamins, when substituted for meat, improve the nutritional value of the end product. PBMAs should be further researched to ensure that they have a higher protein volume, contain enough vitamins, and have suitable safety and sodium levels. Currently, PBMA is one of the very few inventions that can meet the animal protein demand worldwide, benefit public health, and help alleviate environmental issues.

Overview of current regulations and labeling requirements for meat substitutes
This chapter covers global meat substitute regulatory frameworks and the use of labels for plant-based and cultured products that are gaining popularity and adoption due to their advantages. However, it defines how some of the more recent innovations in plant-based food products aim to increase consumers’ appeal by focusing on sensory aspects such as taste, texture, and visual features. In India, the Food Safety and Standards Authority (FSSAI) is working on the regulations regarding vegan products. However, there still seems to be a lot of confusion regarding the labeling of plant-based and cultured meat products. Countries like Singapore and France have implemented classification systems that address consumer issues. The European Union and the United States have divided viewpoints concerning compliance with the rights of consumers and the trends of the market. At the same time, countries such as Australia, New Zealand, Japan, as well as South Korea have demonstrated classifying novel food categories through local traditions and customs sensitivities. This chapter explores how alternative proteins might help with the ethical, financial, and environmental issues raised by traditional meat production. Consumers worry about price, flavor, texture, and impressions of being highly processed; however, this limits market expansion. It emphasizes how governments, nongovernmental organizations, and businesses collaborate to shape policy, finance research, and raise public awareness. In relation to more general food security and climate goals, it promotes integrated public-private partnerships, worldwide policy harmonization, and innovation ecosystems to guarantee the sustainable expansion of alternative protein sectors.

Plant-based milk alternatives from cereals: Sensory properties and consumer preferences in Indonesia
Introduction: The growing interest in plant-based milk alternatives has prompted the exploration of novel cereal-based ingredients for developing substitutes for dairy milk. This study aimed to investigate the sensory properties and consumer preferences of plantbased milk alternatives derived from cereals, including red rice, rice bran, and sorghum.
Methods: Four cereal-based milk alternatives were developed, including samples made from red rice, red sorghum, white sorghum, and rice bran. In addition, a commercially available rice milk was included as a reference sample. The study employed a cross-sectional study design with a total of 135 participants (mean age 29.8 ± 10.1 years) who participated to evaluate the sensory profiles of the cereal-based milk samples using CATA (Check-All-That-Apply). In addition, the acceptance of each sample was also assessed.
Results: The results indicate that all the cereal-based milk alternative samples exhibited distinct sensory profiles, which may influence consumers’ acceptance. Among the samples, milk alternatives made from red rice and white sorghum were significantly preferred (p < 0.001), whereas the sample made from rice bran was the least preferred (p < 0.001).
Discussion: The sensory attributes of cooked rice aroma, nutty aroma, nutty taste, vanilla aroma, sweet aroma, sweet taste, and violet-like visual color of violet-like were associated with consumer liking. In contrast, attributes of rancid, uncooked taste, bran taste, bitter taste, and sandy texture may be associated with disliking.
Conclusion: This study highlights the potential of red rice and sorghum as promising ingredients for developing plant-based milk products, which serve as a foundation for further research and product development in the growing market of dairy alternatives.

Protein quantity and quality across a spectrum of plant-based meals: Analysis of a large national dietary survey
Rationale: Adequate protein intake is essential for older adults to maintain muscle mass and prevent sarcopenia. In (clinical) practice, the transition towards diets with ≥60% plant-based proteins may affect both protein quantity and quality. This study aimed to assess the protein content, sources, and quality of predominantly plant-based meals from a large national survey, offering insights to support this dietary transition.

Scientific advances in meat substitute technologies
Recent advancements in meat substitute technologies have revolutionized the production of sustainable and ethical alternatives to conventional animal-based proteins. Cellular agriculture, which involves cultivating animal cells in controlled laboratory environments, has emerged as a key innovation in producing cultured meat. This process eliminates the need for livestock farming, offering a more ethical and environmentally friendly option. Advanced food processing techniques, such as extrusion, high-moisture extrusion, and 3D printing, are being employed to create complex protein structures that closely replicate the taste, texture, and nutritional profiles of traditional meat products. In addition to cellular agriculture, fermentation processes, particularly for mycoprotein, are gaining prominence for producing protein-rich, fungi-based meat substitutes. These methods use agro-industrial byproducts to efficiently generate sustainable protein sources. Plant-based food processing has also benefited from emerging technologies such as shear cell processing, ohmic heating, electrospinning, and 3D printing. These innovations enable the creation of meat analogues with fibrous structures and improved textural qualities, mimicking the mouthfeel and appearance of animal-derived products. Fungi-based meat alternatives, primarily mycoprotein, have gained attention due to their efficient use of resources and high nutritional value. Techniques like submerged fermentation, solid-state fermentation, and surface culture are pivotal in producing mycoprotein at scale. Additionally, cultured meat production continues to advance through innovations in tissue engineering, including the development of bioreactors and serum-free media, which enhance scalability, reduce costs, and improve sensory characteristics. These scientific advancements in meat substitute technologies address critical environmental, ethical, and health challenges, paving the way for a more sustainable and equitable food system.

Still niche? Stakeholder perspectives on growing the plant-based meat and plant-based dairy industries
Shifting toward plant-based diets is a crucial aspect of mitigating climate change. As part of this transition, growing the plant-based meat and plant-based dairy industries has significant potential to reduce the environmental impacts of food systems in Western countries. To date, little research has examined the systemic challenges faced by stakeholders involved in developing and supporting these industries. By applying a multi-stakeholder perspective, our study addresses this gap in the literature, exploring the drivers and barriers influencing industry growth. Semi-structured interviews were conducted with 15 respondents representing consumers, manufacturers and retailers. Reflexive thematic analysis was applied, identifying seven overlapping themes applicable to both industries. Findings indicate that support for plant-based products is often grounded in sustainability goals and belief that newer plant-based alternatives can effectively meet consumer expectations. However, industry growth is restricted by structural challenges, including the influence of the meat and dairy sector, negative consumer perceptions, and the high financial risk of investing in emerging alternatives. Stakeholders identified two key changes needed: greater industry investment and more effective strategies to stimulate consumer demand. Applying the multi-level perspective (MLP) to interpret findings suggests that the plant-based meat and plant-based dairy sectors are still operating as niche industries, and that sector growth depends on changes at both the niche and regime levels to fully integrate plant-based meat and plant-based dairy into the food system. This research contributes original insights into the dynamics of sustainable food system transformation by foregrounding stakeholder experiences across multiple points in the value chain.

The myth of misleading labels: Examining consumer understanding of plant-based meat and milk analogues
Recent legal and policy efforts have aimed at changing plant-based meat and milk product analogue labels to reduce consumer confusion. These proposed changes assume (a) that there is confusion about key aspects of plant-based products, and (b) that the proposed changes will fix that confusion if it exists. In Experiments 1a (N = 380) and 1b (N = 246), we provide evidence that there is little confusion about plant-based products when participants are presented with product labels about key product facts (e.g., contains animals, contains lactose). In Experiment 2 (N = 250), changing labels seemingly in accordance with proposed policies did little to reduce confusion but did decrease confidence in those judgments and made it more difficult to know what to use that product for or what the product would taste like. In Experiment 3 (N = 311), those results were replicated in a jurisdiction specific sample taken from residents of Texas. These results suggest that prominent proposals to change plant-based meat and milk analogue labels may be unnecessary and, in some cases, could be harmful.

Towards intelligent cultivated/cultured meat factories: The synergy of AI, 3D bioprinting and automation in next-gen food manufacturing
Global population growth, urbanization, and growing incomes have increased the need for protein, stressing the urgent need for sustainable alternatives to conventional livestock farming, which presents serious ethical, scalability, and environmental issues. Cultured meat, made by culturing animal cells under a controlled environment, is a possible alternative that can lower greenhouse gas emissions, land use, and animal suffering. However, large-scale production of cultured meat with the same texture, structure, and viability as conventional meat remains highly challenging. Even though three-dimensional (3D) bioprinting has become a crucial technique for precisely engineering meat-like, organized tissues, existing systems have hurdles with automation, repeatability, and throughput. The potential of recent (2020–2025) advancements in automation, Machine Learning (ML), and Artificial Intelligence (AI), primarily from the fields of regenerative medicine and tissue engineering, is examined in this paper along with its relevancy to large-scale cultured meat bioprinting.AI-driven process optimization, predictive modelling of cell viability and growth, real-time feedback through sensor-based control systems, robotic integration for material handling and post-processing, automated bioreactor integration, and early company adoption of AI and automation are some of the main topics. Research highlights advantages including less trial-and-error, improved accuracy with robotic systems, computer vision-based real-time print adjustments, and closed-loop feedback that requires less human engagement. The groundwork for intelligent, high-throughput “smart bioprinting factories” is laid by these technologies. This analysis maps out a route toward scalable, affordable cultured meat production with significant promise for industrial use and sustainable protein supply by combining advancements in AI, ML, and robotics.

Animal product consumption
Indicators and determinants of red meat production in Egypt: A case study of Al-Amreya region
The animal production sector is considered one of the important economic sectors, as it contributes about 35% of the value of agricultural production, which amounted to 1070 billion pounds in 2022, in addition to its role in providing animal protein necessary for human health. The research aims primarily to study the most important indicators and determinants of red meat production in Egypt during the period 2005-2022 by studying the development of the number of farm animals producing red meat in Egypt, the development of production and consumption, the average per capita share and the food gap of red meat in Egypt, and identifying the most important determinants of red meat production and the most important problems and obstacles facing red meat producers in the study area through published secondary data and the study sample in the Ameria area in Alexandria Governorate.
Results of the research:
The number of cows heads took a general decreasing trend with a value of about 0.029 thousand heads and an annual decrease rate of about 0.4%, at a morale level of 1%, while the number of buffalo heads took a general decreasing trend with a value of about 0.061 thousand heads and an annual decrease rate of about 0.8%, at a morale level of 1%, and the number of sheep heads took a general decreasing trend with a value of about 0.058 thousand heads and an annual decrease rate of about 0.7%, At a significance level of 1%, the number of goat heads took a general decreasing trend with a value of about 0.078 thousand heads and an annual decrease rate of about 1%, at a significance level of 1%, while the statistical significance of the amount of annual change and the annual growth rate was not proven at the usual significance levels for the number of camel heads during the study period.
The average annual domestic production of red meat was about 763 thousand tons, with a coefficient of variation of about 18% and an annual decrease rate of about 0.5%, at a significance level of 1%, while the average annual domestic consumption of red meat was about 1138 thousand tons, with a coefficient of variation of about 13% and an annual decrease rate of about 0.2%, at a significance level of 1%. The average annual food gap of red meat was about 376 thousand tons. While the average annual self-sufficiency in red meat was about 67%, the average annual per capita share of red meat was about 10 kg/year, with a coefficient of variation of about 20% during the study period.
Through statistical estimation of red meat production functions in the study sample, it was found that there is a direct, logical, economic and statistically significant relationship between the amount of red meat produced in tons as a dependent variable and the number of animal units, the average weight of the animal when purchased in tons, and an inverse relationship with the amount of dry filler feed in tons as explanatory variables for the model, and that these variables explain 97% Among the changes that occurred in the model, with regard to the first holding category of farms (less than 10 heads of cattle), while in the second holding category (10-50 heads of cattle), it was found that there is a direct, logical, economic and statistically significant relationship between the amount of red meat produced in tons as a dependent variable and the number of animal units, the average weight of the animal when purchased in tons and the amount of concentrated feed in tons as explanatory variables for the model, These variables explain 97% of the changes occurring in the model. For the third holding category (more than 50 heads of cattle), there is a direct, economically logical, and statistically significant relationship between the quantity of red meat produced in tons as the dependent variable and the number of animal units and the average weight of the animal at purchase in tons as explanatory variables for the model. These variables explain 97% of the changes occurring in the model.
Related to the results of the study, it recommends encouraging investment in livestock production projects, given the results’ low self-sufficiency in red meat. This requires expanding the local production base and reducing dependence on imports by providing appropriate investment incentives and improving the legislative and regulatory environment for this vital sector. Focusing on improving and developing local breeds with high production efficiency and expanding feed cultivation and improving veterinary services.

Steak is not the only meat: Men opt for unconventional meat products when mitigating masculinity threat
Grounding our research in the symbolic self completion theory, we explored situations in which men are particularly motivated to consume meat and unconventional meat products, even when considered disgusting. We tested whether men compensate their experience of masculinity threat by opting for meat, including red meat, white larvae and offal. We also examined whether disgust towards products and their perception as feminine affect such decisions. In Study 1 (N = 247), men opted for more meat products when feeling self-incomplete in their masculinity. In Study 2 (N = 256), spicy edible larvae were preferred by men made to feel incomplete in their masculinity compared to those who felt complete, but the effect was significant only when considering the extent to which insects were perceived as disgusting and repulsive. Study 3 (N = 156) showed that preparing disgusting offal during a cooking course may compensate for feeling self-incomplete but only when it is not perceived as feminine. We discuss new research avenues and point to other boundary conditions that affect using various meat products in order to compensate for feelings of self-incompleteness in masculinity.

Animal welfare
Aligning agricultural policy: Discrepancies between public and farmer priorities
Agricultural policy in Europe is the subject of extensive debate due to the unmet agri-environmental goals, despite high levels of support. For example, the public is critical of agriculture’s impact on the environment and animal welfare. At the same time, farmers protest due to low incomes and high bureaucracy. This apparent polarisation may hinder progress in agricultural policy reform, and a more nuanced understanding of the perceptions of both non-farmers and farmers is needed. This study systematically compares non-farmers’ and farmers’ preferences and levels of consensus across a comprehensive set of agricultural policy goals using surveys in Switzerland (N = 1668). We also assess the polarisation among farmers, non-farmers, and the entire population. We find consensus and polarisation in the perception of agricultural policy goals among Swiss farmers and the general public. Both prioritise domestic food production and farmers’ income as main policy goals. However, non-farmers put more emphasis on low food prices and agri-environmental goals than farmers. We find strong divides within the farming population, particularly regarding the need to mitigate climate change. Our analysis provides key insights for policymakers. Firstly, the broad consensus on different agricultural policy goals underlines the legitimacy of focusing on multiple objectives that support the multifunctional role of agriculture. Secondly, farmers are not homogeneous but have differing views, particularly regarding environmental objectives, especially those related to reducing greenhouse gas emissions. Policies need to take this heterogeneity into account, for example, by more efficient allocation of agri-environmental payments. Thirdly, while farmers and non-farmers generally agree on the importance of securing farmers’ incomes and food production, there are divergent views when it comes to reducing food prices and environmental impacts. Future agricultural policy reforms must find a balance between environmental goals and safeguarding farmers’ incomes, while also ensuring affordable food prices.

Flexible self-protection as evidence of pain-like states in house crickets
The possibility that insects experience pain is a frontier question at the intersection of animal behaviour, comparative cognition, and philosophy of mind. Interest has been fuelled not only by anatomical discoveries but also by expanding behavioural and comparative evidence. Under leading frameworks, the most informative behavioural indicators of pain-like experience include flexible, targeted responses to harm that suggest more than stereotyped, reflexive withdrawal. Here we tested for such responses in the house cricket (Acheta domesticus), a species of both evolutionary and commercial importance. Using a fully blinded, within-subjects design, we applied either noxious heat, tactile contact, or no contact to a single antenna under both lower- and higher-stress environmental conditions and recorded subsequent grooming behaviour. Crickets were significantly more likely to groom the noxiously stimulated antenna, and did so for longer durations, than under control or tactile treatments. Grooming also showed a distinct temporal profile, with elevated activity sustained across the early observation period. Environmental condition and sex had no effect, indicating that self-protective grooming was expressed consistently across contexts and sexes. These findings provide robust evidence of flexible, site-directed self-protection in Orthoptera, addressing a key gap in the evidence base for pain-like states outside vertebrates. Such evidence strengthens the case for precautionary consideration of insect welfare, while also bearing on the broader scientific question of how felt experience is distributed across the animal kingdom.

How to decide when the protection of life and welfare is no longer compatible with each other in a compromised animal: Ethical analysis of moral and legal demands
One of the most challenging decisions that veterinarians and animal owners face is whether to treat or kill diseased or injured animals. While this decision is hard in any setting, it is pronounced in the context of farm animals, where the sheer number of animals amplifies the frequency of such decision-making. In Germany, animal welfare laws protect both the well-being and the life of the animal. However, these two protected goods can become mutually exclusive at times, for instance, when the animal’s well-being has deteriorated or is assumed to be deteriorating to a point where it becomes questionable if an extension in lifetime is in the animal’s best interest. In such cases, where inaction is ethically and legally untenable, animal owners and veterinarians must make a decision that considers not only the medical circumstances but also the moral and legal demands of the situation, in addition to the sometimes-opposing interests of the different stakeholders (animal, animal owner, veterinarian). To address this problem, we developed a decision-making tool and visualisations that help navigate the ethical dimension of these decisions. These tools can serve as a means for reflection about one’s own decision-making. Moreover, results serve as a precursor for developing more ambitious and holistic decision-making tools aiming to provide practical, medically and ethically sound recommendations. Notably, the aim of our decision-making tool and the ethical analysis is not to replace the individual decision-making process of the animal owner or veterinarian; it is to supplement it by providing structure and perspective.

Implementation and improvement of animal-based measures for environmental management assessment items in animal welfare certification system
South Korea has implemented an animal welfare certification system for seven livestock species since 2012. However, the system faces limitations such as ambiguous assessment criteria, reliance on subjective judgment, and insufficient use of animal-based measures. Although some studies have investigated animal-based measures for farm animals raised in South Korea, their integration into the certification standards remains limited – especially in environmental management, where housing conditions play a critical role in determining welfare outcomes. This study discusses the limitations of environmental management assessment criteria in the animal welfare certification system for cattle and proposes directions for applying animal-based measures. Cattle are vulnerable to glare, contrast and ununiform lighting, yet current certification standards specify only illuminance levels focused on worker comfort. Under such conditions, showed behavioral changes such as stopping, changing stride, increasing moving speed, avoiding obstacles, and hesitation in walking. Current air quality assessments are limited in scope and primarily rely on subjective sensory evaluations of the evaluator. Exposure to airborne pollutants can cause tearing, nasal discharge, coughing, and corneal ulcers in cattle, and further research is warranted to clarify the relationship between airborne pollutants and associated clinical symptoms in cattle. Temperature assessment relies on facility status and daily records, but the effect of the facility and the perceived temperature can differ even in the same environment due to various factors. Panting and shivering scores have been used in several studies as indicators of cattle’s physical responses to thermal stress, indicating a need for further validation for cattle breeds raised domestically. Cattle are also vulnerable to high-frequency, biological, intermittent, and sudden noises from inside and outside the farm; however, noise standards are not clearly defined in current certification criteria, leading to subjective assessments. Such noise exposure can provoke increased heart rate, agitation, freezing, milling, and refusal to walk, which can be identified through the pryer reflex. In this way, physical responses of cattle under different environmental management levels can be interpreted as indicators of discomfort with the housing environment. Applying animal-based measures to assess welfare levels for environmental management may increase the effectiveness of assessments through more accurate and objective criteria.

Optimising the selection of welfare indicators in farm animals
Introduction: Risk assessment (RA) frameworks are increasingly being applied to improve the welfare of farmed animals. These frameworks have at their core, a logic chain linking welfare hazards (risks) with one or more welfare consequences which, in turn, are each measured by one or more welfare indicators. Effective and efficient monitoring of animal welfare often involves the selection of a subset of indicators from a large pool. Selecting ‘iceberg indicators’ could be advantageous due to their association with multiple welfare consequences. However, no standardised, data-driven method exists to select optimal combinations under practical constraints. This study addresses this gap by creating an algorithmic approach to optimise indicator selection.
Methods: The work was conducted in six phases: (1) construction of a structured database of welfare indicators; (2) a proof-of-concept study; (3) design of a greedy selection algorithm; (4) enhancement of the algorithm using branch-and-bound and backtracking methods; (5) performance and sensitivity testing, and (6) creation of two case studies. A dataset of 382 animal welfare indicators across seven farm species was compiled from scientific opinions published by the European Food Safety Authority (EFSA) and from other published literature. The EFSA scientific opinions contain data acquired through a rigorous process of literature reviews and expert elicitation and consensus panels to link welfare indicators with their associated welfare hazards and welfare consequences. To enable algorithm development, the Coverage of each welfare indicator was first determined by calculating the number of unique welfare consequences to which it was linked. Metadata such as the Impact of welfare consequence [Low (1) or High (2)], Ease of hazard mitigation [Easy (1), Moderate (2) or Difficult (3)], and Ease of indicator use [Easy (1), Moderate (2) or Difficult (3)] was generated through an expert elicitation process. These data were standardised using max–min normalisation across all criteria, and an objective function was defined which enabled indicator subset selection according to various user-defined criteria. Optimisation was performed using both a greedy algorithm and an enhanced algorithm incorporating backtracking and branch-and-bound solvers. Algorithm performance and robustness were evaluated through sensitivity analyses, scenario testing, and computational benchmarking.
Results: The greedy algorithm offered computational efficiency but incorporated suboptimal plateaus in Coverage as additional indicators were combined. The enhanced algorithm identified globally optimal combinations within 0.2 s for all species, regardless of problem size. In a broiler chicken case study, the enhanced algorithm removed indicators that were moderately difficult to use. A pig case study showed that the enhanced algorithm combined the same welfare indicators as the greedy algorithm but validated the added value of multi-criteria scoring by identifying high-impact, easy-to-implement indicators suitable for welfare certification.
Discussion: The enhanced algorithm was able to move beyond the selection of iceberg indicators, by incorporating multiple selection criteria to inform welfare indicator choice. The enhanced algorithm is data-agnostic and enables users to optimise indicator selection with diverse datasets spanning research, industry, and policy contexts. Its flexibility supports the development of tailored applications for different stakeholders. Future work should explore processes to determine weighting values, scenario testing, robustness, and stakeholder engagement to maximise both relevance and practicality.

Open cage farrowing system: Balancing welfare and productivity
The transition to open cage farrowing systems (also known as temporary crates) represents a pivotal advancement in improving animal welfare in pig production. This shift responds to increasing societal and legislative demands for more ethical livestock management. However, it introduces significant challenges for both farmers and animals, requiring a re-evaluation of traditional management practices. This study investigates the management of sows in open cage farrowing systems, focusing on welfare, productivity, and practical implementation. The key areas of exploration include housing design to balance sow freedom and piglet safety, addressing the behavioural and physiological needs of sows, and mitigating health risks such as crushing and hygiene concerns. The study monitored farrowing outcomes in 40 sows divided into two groups: a) Control group (C), where sows were housed in closed temporary crates from farrowing to weaning, and b) Open Sows group (OS), where the crates were opened on day 3 postpartum. Data collection included litter weight measurements at days 1, 8, 15, and 25 postpartum, health indicators for piglets (e.g., diarrhoea, limb disorders), sow dry matter intake, and sow health indicators. The findings revealed a higher incidence of piglet crushing in the OS group compared to the C group after cage opening (10.2% vs. 2.4%; p< 0.01), with a greater proportion of OS sows involved in crushing episodes (60.0% vs. 25.0%; p< 0.05). At weaning, while the average number of piglets per litter was higher in the C group (13.1 vs. 12.0; p< 0.001), no differences were found in number of total weaned piglets per group (262 C vs 240 OS; p = 0.157), and the average piglet weight was greater in the OS group (7.69 kg vs. 6.64 kg; p< 0.001). These results emphasise the trade-offs in open cage farrowing systems: while increased sow mobility may elevate the risk of piglet crushing, it also improves piglet growth and weaning weights without reducing the total number of weaned piglets. From an economic perspective, the higher growth rates and weaning weights in the OS group may help offset crushing losses, offering a potential pathway to greater confidence in the economic sustainability of alternative farrowing systems. The results provide a critical foundation for addressing farmer concerns about open cage farrowing systems, proving that such systems, while challenging, can align animal welfare improvements with economic viability through careful management practices.

Student reported learning of swine and dairy welfare concepts following a virtual reality livestock farm experience
Undergraduate (n = 32), graduate (n = 33), and veterinary students (n = 6) visited a virtual reality (VR) tour of a swine (n = 29) or dairy (n = 42) farm. Each tour featured a 360-degree video with voiceover and a self-guided exploration of farm basics and animal welfare challenges. The self-guided VR tour provided interactive hotspots for information. Students completed surveys pre- and post-tours, using a Likert scale from 1 (strongly disagree) to 5 (strongly agree). Students who experienced the dairy farm showed significant increased agreement on welfare statements (p < 0.01), including that “Dairy producers care about cow welfare.” Similarly, swine tour students agreed more with “Current swine husbandry practices result in positive animal welfare” (p < 0.01). After the dairy tour, students agreed more on practices like the importance of biosecurity in transitioning barns (p < 0.01), while swine tour students showed no change (p = 1.0). Overall, virtual tours increased awareness of animal welfare (p < 0.05). More research is needed, but VR tours may effectively enhance classroom discussions on animal welfare.

Aquatic animal welfare
Advancing sustainable aquaculture: enhancing production methods, innovating feeds, promoting animal welfare, and minimizing environmental impact
Aquaculture has become the fastest-growing food production sector, driven by the rising global demand for seafood and the urgent need to reduce pressure on overexploited fish stocks. With global aquaculture production reaching an unprecedented 130.9 million tons in 2024, aquaculture is expected to further expand in the coming decade. Yet, this growth comes with challenges, including the reliance on fishmeal and fish oil, the impact of intensive farming on animal welfare, and the environmental costs of resource use and waste discharge. Addressing these challenges requires innovative approaches to nutrition, husbandry, and production systems that reduce ecological footprints while ensuring resilience and animal health.
The Special Issue “Advancing Sustainable Aquaculture: Enhancing Production Methods, Innovating Feed, Promoting Animal Welfare, and Minimizing Environmental Impact” was launched with this vision in mind. Its goal is to highlight new research that not only deepens scientific understanding but also delivers practical solutions for aquaculture sustainability. The nine articles published in this collection span key themes—feed innovation, stress physiology, and system-level integration—illustrating the breadth and dynamic nature of this rapidly developing field.

Farmer perception of fish welfare in rainbow trout farms
This preliminary study aimed to assess farmer perceptions of on farm welfare in rainbow trout (Oncorhynchus mykiss) as for potential welfare indicators, risk factors, and corrective measures based on their experience and evalutation. A structured questionnaire covering five areas—farm data, management, on farm welfare, welfare at slaughtering, and perception at the wholesale level—was administered through interviews with 11 breeders man aging a total of 23 farms in northeastern Italy, where 70% of Italian trout production occurs. The collected data underwent a descriptive analysis and were then categorized based on welfare criteria, risk factors, and corrective measures following the four welfare principles: Good Housing, Good Feeding, Good Health, and Appropriate Behaviour. Potential welfare indicators were abnormal behaviours (as for species-specific behaviour, swimming, social behaviours, human-fish relationships), performance, clinical signs of illness and mortality. The interviewed farmers identified trout welfare as influenced by both uncontrollable external factors (light, noise, piscivorous birds) and controllable environmental conditions (tank bottom, water flow, water quality) (Good Housing); as well as feed composition (proportion of vegetable ingredients), pellet type (sinking or floating), feeding frequency (Good Feeding); and fish health status (lesions and diseases) (Good Health). Risk factors for Appropriate Behaviour are related with those identified in the previous principles. In view of developing on farm welfare assessment protocols, the validity, repeatability and feasability of the welfare indicators used by the farmers should be tested under field conditions.

Laksvel - A standardised, operational welfare monitoring protocol for Atlantic salmon held in sea cages
To measure and record fish welfare in a consistent manner, a detailed protocol is necessary for how measurements and scores should be conducted. This report describes three environmental based (oxygen, temperature, and salinity), three group based (behavior, appetite, and mortality), and fourteen individual based operational welfare indicators for use in salmon grow-out facilities. All indicators are divided into four levels that indicate increasing welfare burden at each level. The protocol includes instructions on how the indicators should be measured or scored, and for the individual-based welfare indicators, there is a guide with a description of each indicator and three example images for each of the three levels indicating deviations (scoring levels 1-3).

Modeling cage-level dissolved oxygen variation within salmon farms
Dissolved oxygen (DO) is a critical factor for animal welfare, growth, and production performance in Atlantic salmon sea cage farming, but challenging to monitor and manage in the complex farm environment. Variation in DO stems from complex interactions between the local environment, large fish populations, farm structures, and production activities, and understanding this intra-farm variation is key to improving DO management.In this study, we explore the potential of combining in-situ environmental measurements and production data with a mathematical model that simulates DO variation at the cage-level. We apply this model to three commercial sea cage farms, evaluate the extent of production impairment not captured by in-situ measurements and identify key drivers of DO variation using a statistical model.The results show substantial intra-farm variation in DO. The model output indicates significantly worse conditions than seen directly from the DO measurements, with a production impairment up to 65 percentage points greater at the modelled cage-level. From July to October, model outputs indicate that all sites experienced continuous DO levels below maximum feed intake, for 62-80% of the time, and some periods of heightened welfare risks. While environmental factors are identified as the main drivers of in-cage variation, 13-15% is caused by farm-controlled factors, including cage position, biomass and daily feed ration.Our findings show that integrating in-situ measurements with modelling reveals insights into the in-cage DO levels across farms without dense sensor networks, offering a method for aligning operations to environmental restrictions and a greater precision in farm management.

Preventive strategies and health management framework for controlling fish diseases in aquaculture: Review paper
Aquaculture has become one of the most rapidly expanding food production industries of the planet, but its sustainability is rapidly diminishing due to the popularity of infectious diseases that lead to substantial financial losses and deterioration of fish welfare. The management of diseases in aquaculture will require transition to preventive treatment of diseases through an integrated health management system rather than reactive treatment. The present review summarizes the existing evidence in the area of preventive measures, such as biosecurity, water quality control, vaccination, the use of immunostimulants, pro- & prebiotics, and dietary interventions, the use of early disease detection techniques. The framework focuses on the use of a holistic approach through the integration of environmental management, host resistance enhancement, and pathogen control to minimize outbreaks of diseases. Besides, the paper emphasizes the significance of the ecosystem-based management, training of farmers, and policy-level intervention to reinforce the measures of the disease control. Issues like antibiotic resistance, the effects of climate changes, and inaccessibility to vaccines in the developing world are also addressed. Through the description of strengths and weakness of current approaches, the review offers a holistic basis of designing sustainable, preventive and adaptive health management models within aquaculture. The results support the importance of using multidisciplinary efforts to achieve fish health, food security, and sustainability of the aquaculture industry.

Attitudes toward veg*nism
Knowledge of and attitudes towards vegan and vegetarian diets amongst students at a university located in rural Poland
Background: Healthy plant-based diets, such as vegan and vegetarian diets, as well as planetary health diets, meet the recommendations of sustainable dietary patterns and are healthier for both the planet and humans. The adoption of these dietary patterns may depend on socio-demographic factors and individual motivations. Aim: This study aimed to analyse the association between socio-demographic factors and knowledge and attitudes towards vegan and vegetarian diets amongst university students. Methods: This anonymous survey included 241 students from a university in rural Poland. The association between respondents’ socio-demographic factors and the investigated categorical variables was analysed. Results: Only three respondents followed a vegan or vegetarian diet during the study. In general, the respondents were unwilling to reduce their meat consumption (55.9%). The willingness to do so was significantly higher amongst women than men (39.4% vs. 15.1%; p = 0.0002), meat avoiders than omnivorous respondents (68.4% vs. 25.0%; p < 0.0001) and health discipline students than non-medical students (47.7% vs. 23.0%; p = 0.0004). Higher awareness of the benefits of plant-based diets was confirmed amongst women, health discipline students and those who avoided meat. Vegan and vegetarian diets were perceived amongst the total number of respondents as more expensive (56.9%) and more difficult to follow compared to omnivore diets (74.7%); in turn, substitutes for animal products were as easily accessible (61.8%). The term ‘planetary health diet’ was used by only 13.7% of the students surveyed. Conclusions: Promoting the benefits of plant-based diets is important, especially in small, traditional communities, where previously acquired patterns mostly determine dietary choices. The inclusion of issues involving planetary health and sustainable diets into curricula and non-medical fields will enable their promotion amongst young adults in general.

Climate change and sustainability
Climate change and consumers’ food choices towards sustainability: A narrative review
This narrative review explores key issues surrounding climate change and diets, highlighting individual-level dynamics and structural constraints to implementing policies that prioritize sustainability through a political economy lens. Strong interconnections exist between climate change and agri-food systems. Current eating patterns are unsustainable, threatening both human and planetary health. Hence, the urgency of promoting “Planetary Health Diets.” Available evidence confirms that the healthiest diets exert the least pressure on the environment. Partially substituting meat with plant-based alternatives and reducing the intake of ultra-processed foods can contribute to more climate-friendly dietary patterns. Environmental issues, eco-emotions, health-related dietary motivations, and ethical aspects likely encourage consumers to adopt more sustainable eating habits. In contrast, high prices, consumers’ low acceptance, low education, lack of a standardized definition, and weakness in the current information-based instruments related to sustainable food production pose significant challenges to consumers’ choices. Effective governance at global, national, and local levels is pivotal. Integrating sustainability issues in national food-based dietary guidelines, education and awareness campaigns, along with reforming public food procurement and offering economic incentives for sustainable foods have the potential to foster the transition towards a healthy sustainable eating. Current dietary patterns negatively affect both planetary and human health. However, consumers are increasingly inclined toward sustainable food options. While individuals play a role in food choices, structural interventions are essential to ensuring a successful transition.

Diet for human and planetary health: Why we should consider limiting meat?
Climate change is currently the most significant threat to public health, and human activities are the major contributing factor. There is an urgent need to prioritize mitigation strategies at both personal and public policy levels. There is a general lack of belief that changes at a personal level would have a significant effect. However, it is vital to recognize the importance of food consumption on one’s personal footprint and how it can be used as a key feature in mitigation efforts. The Center for Sustainable Systems at the University of Michigan projects that reducing meat consumption per individual by 50% reduces an individual’s carbon footprint by 35% per day and reducing by 90% cuts an individual’s carbon footprint by 51% per day. Additionally, high meat consumption has been associated with increased risks of cardiovascular disease, diabetes, and colorectal cancer. In contrast, plant-based diets are linked to better health outcomes and lower mortality rates. This article is a narrative review and reviews current evidence on the health and environmental impacts of meat-based diets and highlights the potential benefits of plant-forward dietary patterns. These findings support the integration of dietary recommendations into climate and public health strategies. Promoting plant-based diets through clinical guidance and policy initiatives may offer a cost-effective, scalable approach to advancing both population health and environmental sustainability.

Sustainability practices among Connecticut public school districts and opportunities for improvement
Objective
We aimed to explore current sustainability practices in Connecticut Public School Foodservice systems, identify gaps and opportunities to improve sustainability, including farm-to-school education.
Methods
An online cross-sectional survey was developed using Qualtrics on the University secure server. The survey included quantifiable questions related to purchasing practices, school gardens, energy and water conservation, waste stream management, and plant-based menus. Open-ended questions asked what types of assistance would be helpful. In September 2024, the survey was emailed to 147 public school food service directors; 55 responses were received by December. Data were coded and analyzed using descriptive statistics. Text responses were manually coded and summarized. Major Findings &
Conclusions
Local purchasing occurs at 98% of schools (n=55), 98% reporting they sometimes or always purchase local produce and 91% sourcing local dairy. Many expressed interest in increasing their procurement of local meat and poultry. Additionally, 60% of schools participate in farm-to-school activities. Plant-based menu options are reported as an urgent priority, with 58% of schools currently offering them. However, schools remain uncertain about how to enhance sustainability overall and reported that resources to implement comprehensive composting and waste management programs would be helpful. Practical Application: The survey responses serve as a baseline for future research into the evolving sustainability efforts of both school food service and farm-to-school programs. These findings can inform the development of educational initiatives for students, teachers, foodservice staff, and administrative staff within Connecticut school districts—and potentially beyond—by highlighting opportunities to enhance sustainability practices.

Sustainable diets: Exploring knowledge, attitudes and practices of college students using a qualitative approach
Background
Consuming sustainable diets represents one of the global targets to address human and planetary health. Yet research examining the knowledge, attitudes, and practices (KAP) of college students towards sustainable diets is still in its nascence phase in the US.
Methods
Qualitative interviews were conducted to explore the KAP of college students towards sustainable diets in a minority serving institution in North Carolina (summer 2024). Thematic analysis was conducted using NVivo software.
Results
Analyses from qualitative interviews (n = 15) showed four emergent themes. College students have mixed KAP for sustainable diets (theme 1). Albeit the willingness to adopt more sustainable practices, barriers persist (theme 2), including time constraints; limited physical and economic access (availability and cost as barriers for consuming plant-based foods); and mixed social environment influence (family/partner/peer) on sustainable practices among college students. Food and nutrition literacy remain challenges due to difficulty in planning, preparing food, and low confidence in cooking skills. Facilitators to promote awareness and adopt sustainable diets (theme 3) included the influence of social media on students’ choices for sustainable diets, and the potential for schools, universities, and community activities to engage students in sustainability-related issues. Students had mixed perceptions of the government and private sector roles in promoting sustainability (theme 4).
Conclusion
Findings from this formative study helped explore the KAP of young adults towards sustainable diets and can guide the design of evidence-based interventions to promote diets that have lower environmental footprint and better health outcomes.

The impact of the eco-score and the co-presence of Nutri-Score on sustainable food identification by consumers
Eco-labelling is a way to transparently communicate a product’s environmental impact. A universal Eco-Score is under debate, and it remains unclear which form of eco-labelling best supports consumers in identifying sustainable food products, especially in combination with the Nutri-Score. The effectiveness of the Eco-Score on sustainability identification was assessed in two online choice tests (n = 1201, n = 938), by assessing: 1) Eco-Score vs. no label 2) the label design (letter vs. traffic light), 3a) the co-presence of Nutri-Score, and 3 b) similarity versus opposition between Nutri- and Eco-Scores. Results show that without Eco-Score, the overall mean correctness score was 52 % (the change rate of selecting the most sustainable food out of two). With Eco-Score, this improved to 72 % (p < 0.001). The single-letter version slightly outperformed the traffic light version (p = 0.018), particularly among lower-educated respondents. The co-presence of Nutri-Score reduced correct identification slightly (by 5 %), but only when the two scores showed opposite directions (p < 0.001). In conclusion, consumers benefit from a sustainability label to make informed food choices. The simpler letter format is at least as effective as the traffic light version. Although conflicting Nutri-Scores may slightly reduce sustainability identification, the overall positive effect of the Eco-Score remained strong. Adding a sustainability label like the Eco-Score alongside Nutri-Score offers complementary guidance on both health and environmental impact.

Towards more balanced dietary guidelines: Connecting climate, culture, and nutrition
Objective:
The transformation of food systems has emerged as a critical component of global climate action, with food-based dietary guidelines (FBDGs) increasingly recognised as a key policy tool to promote both public health and environmental sustainability. However, despite their importance, many national FBDGs fail to integrate sustainability considerations or adequately support diverse plant-based dietary patterns.
Design:
This review proposes a socioecological framework for enhancing the inclusivity and adaptability of FBDGs, enabling them to better reflect evolving food systems and consumer behaviours while strengthening their role in promoting sustainable and health-conscious diets.

Five key gaps in current FBDGs worldwide were identified: (1) the need for more inclusive food-group classifications that accommodate plant-based protein sources; (2) clearer recommendations for limiting the consumption of animal-sourced foods (ASF) for health and environmental reasons; (3) guidance on obtaining essential macro- and micronutrients from plant-based sources; (4) the inclusion of plant-based alternatives to ASF within dietary recommendations; and (5) comprehensive advice on well-planned vegetarian and vegan diets.
Conclusion:
Addressing these gaps is crucial to ensuring that FBDGs remain relevant to a broad spectrum of dietary preferences, including those motivated by ecological, ethical, religious, and cultural factors.

Dietary change interventions
Are you ready to eat less meat? Consumer segmentation based on the transtheoretical model of behaviour change
Excess meat production and overconsumption have raised concerns worldwide about meat’s potential negative environmental and climate impacts. Reducing these impacts requires behavioural changes among meat consumers as well as an understanding of consumers’ stage of change on their meat reduction journey. The transtheoretical model (TTM) of behaviour change offers the potential to reveal consumer readiness for such changes. This study segmented consumers based on their stages of change (pre-contemplation, contemplation, preparation and action) as conceptualised by the TTM and identified these segments’ psychographic and demographic characteristics. Data were collected via a nationwide online consumer survey in which flyers with a survey link were sent to households in randomly selected postal codes across Switzerland. Cluster analysis (N = 569) using Ward’s method identified four distinct consumer segments: ‘Not willing’, ‘Aware but not ready’, ‘Aware and involved’ and ‘Committed and acting’. ‘Not willing’ consumers appear more likely to be in the pre-contemplation stage of TTM and more sceptical of meat reduction, whereas the ‘Committed and acting’ segment includes meat reducers, who claim to be in the action stage. The ‘Aware but not ready’ are mostly at the ‘contemplation’ or ‘preparation’ stages and ‘Aware and involved’ consumers are at the ‘preparation’ or ‘action’ stages. These two segments are considered the main target groups that are amenable to reducing meat intake. Consumers from these two segments show a greater intention to reduce meat consumption and increase vegetable consumption. Targeted strategies should be developed to guide each consumer segment towards more advanced stages of meat reduction.

Challenging the meat-centric environment: How different social norm triggers affect cognitive dissonance and meat reduction
Reducing meat consumption benefits animal welfare, the environment, and public health. Yet, most food environments remain meat-centric, signaling pro-meat social norms. As a result, meat-eaters rarely experience meat-related cognitive dissonance and meat consumption is reinforced. This study investigated how meat-eaters – both with high and low meat-eating identities – respond when placed in a vegetarian/vegan-centric environment. We hypothesized that such environments signal pro-vegetarian/vegan social norms, thereby triggering cognitive dissonance and, in turn, increasing the choice for meat alternatives. In a 2 (vegetarian/vegan dish availability: 25%, 75%) x 2 (poster: animal welfare, neutral) between-subjects online experiment with a representative Dutch sample (N = 888), we tested how two types of environmental cues trigger distinct social norms in a restaurant setting. As predicted, increased availability of vegetarian/vegan menu options (versus meat options) more strongly influenced descriptive norms, whereas an animal welfare poster (versus neutral) more strongly influenced injunctive norms. Both interventions significantly increased cognitive dissonance via injunctive norms, which in turn decreased meat choice, whereas descriptive norms exerted a direct effect on choice. Furthermore, the availability intervention was more effective at eliciting dissonance among higher levels of meat-eating identity, whereas the poster intervention was more effective among lower levels. These findings demonstrate that cues in the food environment can signal distinct social norms, which influence sustainable food choice through different pathways and resonate differently across identity groups. Understanding these mechanisms provides insights into how environmental cues can be leveraged to accelerate the transition from animal-based to plant-based diets.

Diet transformations in families: Unravelling the meat reduction process with parents as change agents
Reducing meat consumption is widely regarded as sustainable and healthy. Despite its many benefits, modifying or abandoning established eating habits remains challenging for most people. In this paper, we investigate how families change their diets. Specifically, we examine the strategies and actions that one or both parents – acting as change agents – use to facilitate dietary change, as well as household members’ responses to these efforts. We collected data through a qualitative study of thirteen Chinese families living in New Zealand (n = 42), offering a perspective that extends beyond European and American populations. Focus groups and semi-structured interviews were conducted in participants’ homes. Grounding our analysis in construal-level theory and family-systems theory, we identified three stages in the change process: (1) implementing a meat-reduction diet, (2) rebuilding mutual trust and respect, and (3) inspiring household members to develop a sense of commitment and responsibility. We propose a theoretical model that explains the construal shifts – from abstract to concrete and from family-centric to society-centric – that change agents use to reduce their families’ psychological distance from food consumption, thereby enabling dietary change at home. Our work contributes to the literature on family-level dietary change and supports the development of behavior-change campaigns that target families rather than individuals.

Does negative information on conventional meat work as an effective communication strategy to promote plant-based meat consumption?
Purpose
This study aims to explore the efficacy of three different information interventions (negative information highlighting the negative impacts of conventional meat consumption, positive information emphasizing the benefits of plant-based meat alternative (PBMA) consumption, and a combination of these two types) for enhancing consumers’ preference for PBMA.
Design/methodology/approach
In this study, we use a hypothetical choice experiment and a between-subject design to empirically investigate the effects of different types of information on consumers’ willingness to pay for PBMA.
Findings
The results indicate that consumers are unwilling to pay for PBMA, but they are willing to pay a high premium for PBMA labeled as low fat and high protein. We find that negative information, either alone or in combination with positive information, successfully increased consumers’ preference for PBMA. Conversely, the use of positive information alone failed to have the same impact.Practical implicationsOur findings provide important implications for stakeholders in designing effective communication strategies to encourage consumers towards the consumption of PBMA.
Originality/value
This research is the first attempt to explore the effectiveness of negative information (i.e. information on the negative impacts of conventional meat consumption) on consumers’ preference for plant-based meat.

Evaluating nudge and boost strategies for greener meals in food-delivery: An experimental study
Global food systems are responsible for approximately 30% of global greenhouse gas emissions, making a shift toward lower-carbon diets essential for mitigating climate change. While nudges have shown efficacy in steering food choices, concerns persist regarding individuals’ autonomy, transparency and the durability of behavioural change. As an alternative, boosts seek to enhance consumers’ competencies and support informed decision-making. However, there is a dearth of comparative research on nudges versus boosts, particularly regarding their ability to foster a sense of consumer responsibility for sustainable consumption (CRSC) – an important driver of long-term behavioural change. To address this gap, this study evaluates a “default+” nudge and an “information+” boost within a simulated food-delivery environment, while examining CRSC as a potential mediator. Employing a mixed design experiment (2 survey waves: intervention, follow-up; 3 conditions: nudge, boost, control), we collected data from 664 German consumers. Our primary outcome was the estimated CO2 footprint of participants’ hypothetical meal choices, calculated using established secondary emission data. Results show that the nudge intervention significantly reduced participants’ meal-related CO2 emissions, whereas the boost intervention yielded considerably smaller and less consistent effects. However, neither intervention produced lasting effects in the follow-up survey, where choice architecture reverted to the control condition. Moreover, while higher CRSC induced lower emissions, neither the nudge nor the boost elevated CRSC, and thus the hypothesized mediating role of consumer responsibility was not supported. We discuss the theoretical and practical implications of these results for the design of effective sustainable food choice interventions.

Exploring the impact of a traffic light food labeling system on student food choices and selection trends at a university food pantry
Background
Consuming sustainable diets represents one of the global targets to address human and planetary health. Yet research examining the knowledge, attitudes, and practices (KAP) of college students towards sustainable diets is still in its nascence phase in the US.
Methods
Qualitative interviews were conducted to explore the KAP of college students towards sustainable diets in a minority serving institution in North Carolina (summer 2024). Thematic analysis was conducted using NVivo software.
Results
Analyses from qualitative interviews (n = 15) showed four emergent themes. College students have mixed KAP for sustainable diets (theme 1). Albeit the willingness to adopt more sustainable practices, barriers persist (theme 2), including time constraints; limited physical and economic access (availability and cost as barriers for consuming plant-based foods); and mixed social environment influence (family/partner/peer) on sustainable practices among college students. Food and nutrition literacy remain challenges due to difficulty in planning, preparing food, and low confidence in cooking skills. Facilitators to promote awareness and adopt sustainable diets (theme 3) included the influence of social media on students’ choices for sustainable diets, and the potential for schools, universities, and community activities to engage students in sustainability-related issues. Students had mixed perceptions of the government and private sector roles in promoting sustainability (theme 4).
Conclusion
Findings from this formative study helped explore the KAP of young adults towards sustainable diets and can guide the design of evidence-based interventions to promote diets that have lower environmental footprint and better health outcomes.

Moving from treatment to prevention: Benefits and barriers to utilising choice architecture to promote healthy sustainable hospital food. A thematic analysis of stakeholder interviews
Diets prioritising plant-source foods and minimising animal products can prevent disease and reduce the environmental impact of the food system. Hospitals face tight budgets, rising diet-related disease, and carbon emission targets: using choice architecture to increase plant-based diets could support these objectives. This study identifies barriers and enablers to implementing choice architecture in English hospitals to promote healthy sustainable plant-based diets. Fifteen semi-structured interviews were conducted with stakeholders from hospital catering, dietetics, sustainability, public health, and behavioural science using purposive sampling. Inductive thematic analysis of transcripts identified key themes using NVivo [version 14]. Ethical approval was obtained from the London School of Hygiene and Tropical Medicine ethics committee [ref: 30243]. Barriers included poor interdepartmental collaboration, limited workforce capacity and investment, nutritional uncertainties, inconsistent definitions, knowledge gaps, commercial influence and absence of standardised carbon reporting guidelines. Successful implementation is contingent on leadership buy-in, appropriate terminology, educational investment, and robust impact evaluation. Aligning policy, staff collaboration and transparency around industry involvement could elevate plant-based initiatives up the health agenda. Policymakers should provide clear consistent targets, terminology, and standards for evaluation, support the use of pilot case studies, and apply national frameworks for industry engagement. Staff and patient involvement in decision-making, investment in food services, catering staff education, and integrating health promotion at food provision points are key implementation actions. This study identifies opportunities for cross-sector stakeholders to support healthier sustainable dietary choices in English hospitals by altering the choice environment to encourage consumption of plant-based diets.

Predictors of dietary meat reduction in Gen Z college students: A cross-sectional survey using the COM-B model
Overconsumption of meat negatively impacts human and environmental health, and thesechallenges are expected to worsen due to global population growth and increasing meatconsumption. Many consumers appear unwilling to reduce their meat intake, and this resistanceto dietary change is more common among adult men than women. However, data about meateating attitudes and behaviors are lacking for younger generational cohorts. Generation Z (i.e.,those born between 1995 and 2010; Gen Z) is a growing consumer group whose dietarydecisions will have environmental and human health consequences. Little is known about GenZ’s meat consumption habits and behaviors and whether this population exhibits a gender gap inmeat intake. The purpose of this study was to understand the overall dietary patterns, currentmeat consumption habits, and intention to reduce meat intake among Gen Z college students.Additionally, this study aimed to identify demographic factors and COM-B theoretical constructsthat predict meat consumption habits and a reduction in meat intake in this population.A 40-item online cross-sectional survey assessed demographic characteristics (13 items),current meat consumption habits (3 items), intentions and stance toward reducing meat intake (2items), and factors influencing a reduction in meat intake (22 items) among Gen Z collegestudents at two Southwestern Virginia state colleges (n = 1,403). Factors influencing a reductionin meat intake were categorized according to the COM-B theoretical model, where psychologicalcapability (4 items), physical capability (3 items), physical opportunity (3 items), socialopportunity (4 items), reflective motivation (3 items), and automatic motivation (5-items) wereassessed using a Likert scale ranging from 1 = strongly disagree to 5 = strongly agree.Descriptive statistics were used to describe demographic data, dietary patterns, dietary habits ofmeat consumption, and intentions toward reducing meat intake. Generalized linear models(GLM) with Akaike Information Criterion (AIC) model selection were used to assess whethereight demographic factors and six COM-B constructs predict 1) meat consumption habits and 2)the transtheoretical model (TTM) stages of change for reduced meat intake of Gen Z collegestudents.Most students adhered to an omnivore diet (91.9%) and consumed meat 6 – 7 days perweek (65.3%). Most students were also in the TTM pre-contemplation stage of change for meatreduction (81.5%), indicating that they were satisfied with their weekly meat intake and did notsee a need to change it. Gender differences were evident for both meat intake frequency and theintention to reduce meat consumption. Meat intake frequency was best explained by a model thatincluded automatic motivation, gender identification, college institution, reflective motivation,psychological capability, and physical opportunity, with automatic motivation and genderidentification having the greatest effect. In contrast, the intention to reduce meat consumption(TTM stages of change) was best explained by a model that included reflective motivation,automatic motivation, social opportunity, and psychological capability. Both reflective andautomatic motivations were the strongest predictors within this model. These results providefoundational information necessary to design effective interventions to reduce meat intake in Gen Z college students. Targeted interventions that use a multi-faceted approach emphasizingstudent motivations may improve outcomes for behavior change in this population.

Psychological barriers for sustainable diets: Unpacking intention-behavior gaps in meat consumption
Promoting a shift away from meat consumption towards an increased share of plant-based alternatives is a promising strategy for addressing environmental challenges while also improving population health. Many consumers already express a strong interest in adopting more sustainable and healthy diets, however, empirical evidence suggests that there is only a weak link between these intentions and actual dietary changes. To unpack this intention-behavior gap this study explores three research questions 1) What factors explain intentions to reduce meat consumption among meat eaters? 2) How much meat do individuals with reduction intentions consume, compared to those without such intentions? and 3) Among participants with reduction intentions — what factors drive their continued meat consumption? To answer these questions, we developed a survey and recruited a nationally representative sample of Swedish consumers (n = 998). A backwards stepwise regression, including 14 theoretically informed variables, revealed that attitudes— towards meat (β = −0.32) and plant-based proteins (β = 0.35) both — were the strongest predictors of intentions to reduce meat consumption. Individual factors like environmental self-identity (β = 0.13) and gender (β = 0.08) played smaller but meaningful roles as did practical considerations such as the perceived convenience of cooking meat compared to plant-based foods (β = 0.09). Furthermore, although the result showed a significant difference in self-reported meat consumption between individuals with high stated intentions to reduce meat intake and those with low or no intention, the size of the difference was small only (d = 0.15), bordering negligible, reaffirming the suspected intention-behavior gap. Among those with intentions to lower their meat consumption, only two key variables emerged as driving continued meat eating — meat purchasing habits (β = 0.33) and a positive attitude towards mea t(β = 0.17). These results underscore the challenges of translating intentions into action and highlight how different variables are important for a) shaping intentions and b) driving these into actions. While intentions are a needed prerequisite for voluntary behavior change, they sometimes prove insufficient on their own, especially when the aim is to change behaviors heavily governed by habits. Practical implications suggest that focusing on breaking habits and fostering positive attitudes towards plant-based alternatives are key in bridging the gap between intentions and actual diet changes.

The effectiveness of interventions to improve environmentally sustainable and healthy dietary behaviours among European adults: A systematic review
The current global food system poses risks to the environment and human health. In recent years, there has been vigorous activity in Europe to shift people toward sustainable and healthy dietary behaviours (SHDBs). However, existing research on the effectiveness of interventions to promote SHDBs is scattered and a comprehensive synthesis of the evidence across individual, interpersonal, organisational, community and policy levels is lacking. We conducted a systematic review which aimed to synthesise the evidence from research evaluating the effectiveness of interventions to improve SHDBs among European adults. Interventions included those which aimed to 1. Reduce animal-based food intake or choice, 2. Increase plant-based food intake or choice, 3. Increase the intake or choice of fruit and vegetables, 4. Increase the intake or choice of products with low GHG emissions, 5. Reduce food waste. After a comprehensive literature search, 17 studies met the inclusion criteria. Nine studies were considered at high risk of bias, six at moderate risk, and two at low risk of bias. Multi-level interventions that include individual, organisational and food environment levels in a range of food environment settings are likely to be effective strategies to improve SHDBs. Interventions that identify appropriate intervention points to match each specific food environment context and target population are also likely to promote SHDBs. Future research is needed to evaluate the impact of policy-level SHDBs interventions, which were not represented in this review. There will also need to be high-quality research to evaluate the longer-term effects of SHDBs interventions.

Towards ritual intervention in meat consumption practices: The case of meat in Dutch Christmas meals
Meat consumption is widely recognized as socially and culturally embedded, yet sociocultural intervention strategies to reduce meat-eating practices remain underdeveloped. This article aims to help fill this research gap by combining insights from social practice theory, ritual studies, and cultural sociology in order to explore ‘ritual intervention’ strategies. While interventions are usually thought of as initiated from the outside, this article capitalizes on the fact that people both reproduce practices and are able to initiate change through their performance. Using a co-creative approach, we invited young adults to intervene in their Christmas meal in ways that reduce meat consumption and to keep a logbook of their experiences. The logbooks were also used for follow-up interviews. The data were analyzed thematically, to identify distinct intervention strategies. The results show that research participants were able to reduce meat consumption by creatively and often unobtrusively renegotiating the centrality of meat, the ownership of the meal, and the ways in which commensality was achieved. On the other hand, participants found they could not interfere with important values, meanings and objectives associated with meat. Based on this case study, we conclude by articulating lessons for ritual intervention strategies in consumption practices. Such a strategy takes a bottom-up approach, capitalizes on the potential for change through performance, maintains the integrity of practices and identifies entry points for change in the ritual nature of consumption practices.

Universal truths about reducing meat consumption?
Current high levels of meat production and consumption are linked to severe health and environmental issues around the world. One remedy to this situation is a shift towards more plant-based diets. Several factors influence consumers’ meat intake including personal, socio-cultural, and economic factors as well as characteristics of the food environment. An increasing number of intervention studies are addressing these factors to support the necessary diet shift. However, the relative impact of factors on diets as well as the effectiveness of interventions might differ across geographic settings. This literature review describes (i) how far extant intervention studies on meat consumption reduction take the regional context into account, and (ii) whether current findings allow to distill universal factors that effectively reduce meat consumption across regions and countries.

Using interactive education materials to empower children to be future consumers of alternative proteins: A randomised control trial
It is important that healthy and sustainable diets are formed during childhood. Education is a potential strategy to increase acceptance of alternative proteins (AP) in children, though traditional educational materials show mixed effectiveness. We developed an interactive application that educates on the different types of AP (i.e., plant-based meat, cultivated meat, insect proteins) and their manufacturing processes. We tested the effectiveness of this application versus an educational booklet with the same content. Children (N=81; 44=boys; 9-15 years-old) with little perceived awareness of AP were randomly allocated to engage with either educational material. They completed questions measuring perceived knowledge of and willingness-to-try AP before and after engaging with the education materials (pre(T1)-/post(T2)-intervention) and at four-week follow-up (T3). Children were also presented with four AP to assess objective willingness-to-try. Results show significantly longer engagement with the interactive education application compared to the education booklet (p<.001), but there were no significant differences in liking of the materials (p=.210). Perceived knowledge for all AP types significantly improved from pre- to post-intervention (ps<.001) and was maintained for cultivated meat and insect proteins at follow-up (no significant difference between T2 and T3). Willingness-to-try cultivated meat significantly increased from pre- to post-intervention (p=.034), but not for plant-based meat or insect proteins (ps≥.080). There was no significant difference in the overall intake of plant-based meat samples between the two education types. Education, delivered interactively or passively, can increase initial self-reported ratings of perceived knowledge of AP, but repeated engagement may be beneficial to ensure long-term maintenance.

Food systems
Tradeoffs and constraints in food systems transformations
Food systems play an essential role in feeding humanity. Despite improvements over thelast century, food systems still have negative impacts on humans, animals, and the environment.As a result, food systems require substantial transformations to meet sustainability goals. Whilesome win-win opportunities may exist to improve multiple objectives simultaneously through foodsystems transformations, the consequences of large-scale shifts towards sustainability ofteninvolve tradeoffs that, while ranging in severity, are important to understand for decision making.This dissertation includes three separate studies evaluating tradeoffs and constraints in foodsystems transformations. In Chapter 2, I used a simple microeconomic model to characterizerebound effects from reducing food loss and waste (FLW). I found that rebound effects could offsetmore than 50% of avoided FLW. Such rebounds would imply similar percentage reductions inenvironmental benefits and improvements in food security benefits, highlighting a tradeoffbetween these two objectives as a result of reducing FLW. In Chapter 3, I used a novel dataset onregulations to determine differences in the way food industries are regulated in the United States(U.S.). I found that aquaculture is subject to anywhere from 3-72 times more regulations than otherfood sectors in the U.S.. Food industries with low-environmental impacts, like those in aquaculture(e.g. seaweed farming) are also subject to equal or greater numbers of regulations than foodindustries with high-environmental impacts (e.g. beef and lamb). Thus, the U.S. regulatory landscape may disadvantage low-impact food industries, especially aquaculture, in the iiimarketplace. In Chapter 4, I combined environmental and animal welfare impact data to assesstradeoffs in Canadian egg production. I found that cumulative pain for laying hens could bereduced by nearly 60% per kilogram of eggs produced, while increasing environmental impactsby less than 5%. This analysis contributes a novel approach to a small, but growing literaturequantifying and comparing animal welfare to other food systems objectives and reveals anopportunity for a big-win-small-loss tradeoff. Collectively, these three studies highlight theimportance of quantifying understudied and unanticipated tradeoffs and constraints insustainability transformations. My results may be useful to a variety of stakeholders, ranging fromfarmers to policy makers, interested in simultaneously balancing multiple objectives as they seekto transform the food system.

Human-animal relations
Linking men, masculinities and non-human animals in the Capitalocene: Implications for critical studies on men and masculinities
This article critically examines links between men, masculinities and non-human animals in the Capitalocene, where humanity’s exploitation and commodification of other forms of life have led to ecological breakdown and other crises on a planetary scale. While some recent work in CSMM has discussed men and masculinities from posthumanist perspectives, specific engagement with non-human animals and animality remains largely absent. To examine these connections, I draw on existing work in CSMM and other critical approaches, such as critical animal studies, feminist animal studies/ecofeminism, and critical race scholarship. I propose studying men and masculinities from a critical posthumanist intersectional approach that integrates non-human animals and animality. The insights provided in this article can inspire new ways of thinking about men and masculinities in CSMM and facilitate envisioning and practicing more sustainable and ethical material relations with non-human animals.

Psychological predictors of bystander reactions to the abuse of animals and humans
While bystander reactions to violence against humans have been well studied, less is known about how people react to animal abuse. We studied whether the same psychological predictors are relevant to reactions to the abuse of animals and humans. We examined the role of Dark Tetrad traits (Narcissism, psychopathy, Machiavellianism, and sadism), ideologies of superiority (social dominance orientation and speciesism – the belief in human superiority over non-human animals), as well as moral disengagement, self-efficacy, and descriptive social norms in predicting reactions to animal and child abuse. In a survey study (N = 518), participants indicated their general reactions to animal abuse as well as how they would react in a situation depicting the abuse of a dog and a child. The general reactions to animal abuse were best predicted by the Dark traits and the endorsement of the ideologies of superiority, most significantly, sadism and speciesism. Both animal and child abuse elicited high and comparable levels of distress and active response intentions. In addition to the general predictors mentioned above, bystander reactions in the case of animal abuse were predicted by lower moral disengagement and perceived self-efficacy, while it was moral disengagement alone that predicted reactions to child abuse. We discuss the implications of these findings for understanding the relevant psychological aspects of reactions to violence and empowering citizens to react more actively to abuse and violence.

Speciesist journalism: News media coverage on farmed animals and care as a news value
Through framing analysis, this research spans a decade (2013–2022) of news on animal agriculture, focusing on the industry’s constituent bodies, farmed animals, to uncover how journalism operates with speciesism as a societal driving force. Findings indicate that animal welfare is framed as a scientific issue, while environmental news coverage downplays the struggles of these animals within industry operations. To conclude, the normative journalistic standard of accuracy is discussed as functioning primarily within an anthropocentric framework, while the news value of care is suggested as a remedy for social ignorance perpetuated by the press regarding farmed animals.

This study examines factors influencing sustained engagement and disengagement in climate activism, specifically within Extinction Rebellion. Through interviews with 26 current and former activists, we identify 10 barriers and facilitators, organized into 3 themes: Socio-organizational barriers and facilitators, Efficacy perceptions, and Burnout and strategies to avoid exhaustion. Participants discussed the following barriers to engagement, potentially leading to disengagement: (1) a lack of social integration, for example, due to biographical differences or difficulties in finding a clear role; (2) conflicts and disagreements (3) doubts about having an impact; (4) challenges within a non-hierarchical organization, such as unclear decision-making procedures or informal leaderships; and (5) burnout stemming from activism-related stressors; and (6) stressors external to activism. Conversely, factors facilitating engagement were: (1) strong social connections; (2) a pragmatic approach to impact, for example, enabled by having a long-term perspective on outcomes; (3) being driven by moral convictions; and (4) access to organizational and individual strategies to manage stress, including the acceptance of varying commitment levels. The findings suggest that the impact of these barriers and facilitators on the activist trajectory is influenced by one’s motivations for engaging. Our discussion offers insights into fostering sustained engagement in social movements.

Advancing the protection of all animals utilizing policy
As it stands, many humans and industries use animals in exploitative and abusive ways. Our human relationship with animals, as well as the current frameworks which legally permit harmful and oppressive practices, must be transformed in order to address the suffering that humans inflict upon animals. To address this, legal protections can be developed to determine rights for animals, solidify expectations for an ethical and peaceful coexistence between our species and others, and remove animals from the systems that exploit them. Policies can be successful when crafted through the animal perspective, prioritizing their best interests. The policies which advocates craft, support, and lobby for can determine the direction and evolution of animal rights and the progression of meaningful changes for animals. With the passing of bold and inclusive legislation promoting animal rights and the eradication of animal use, animals can be protected from human-inflicted suffering.

Animal rights and indigenous traditions in the century of anthropocentrism
This article focuses on the impasse between dominant society and indigenous understandings of humans’ place in the world and places this impasse in the framework of anthropocentrism versus biocentrism. Indigenous approaches to the human‒animal relationship are fundamentally different in comparison with the normative and policy approaches of contemporary societies. Indigenous people regard animals as equal to humans, and in their biocentric worldview, respect for animals occupies a central place. In contrast, contemporary animal welfare legislation in the world is cementing the perception of a watershed between human and non-human animals. Yet, animal rights discourse in industrialised societies is increasingly moving closer to the indigenous perception, where ethical expectations are channelled into foundational legislative descriptive norms.

Introduction: Animal law between jurisprudential discipline, moral imperative, and advocacy
The book is a collection of papers reflecting the state of the art of contemporary animal law and its relationship to the philosophical idea of animal rights. The chapters present the transdisciplinary influences on animal law, highlighting key scientific, ethical, economic, religious, and cultural contexts of the legal protection of animals. The collection outlines the emerging conceptual and regulatory framework of animal law as a jurisprudential discipline as well as the role of legal practice, strategic litigation, landmark cases, and advocacy in the global development of laws protecting animals. Addressing unresolved questions, the book emphasizes the need for the ongoing engagement of scholars and practitioners in the evolving dialogue crucial to fostering better, fairer, and more compassionate legal systems, legislation, and practice of law.

Meat taxes or plant-based subsidies? A multi-country consumer segmentation and profiling on willingness to pay for animal- versus plant-based meat and dairy products
A gradual shift from animal-based consumption toward more plant-based diets is crucial for public and planetary health. However, one practical barrier for this protein transition includes the (perceived) financial accessibility of plant-based alternatives, fueling policy debates around strategies such as animal-based taxes versus plant-based subsidies. We further explore this tension by examining whether consumers in a large multi-country sample can be reliably distinguished based on their relative willingness to pay (WTPΔ) for animal- versus plant-based products across meat and dairy categories. We subsequently profiled emergent segments on psychographic characteristics, such as their readiness to reduce animal-based consumption (i.e., behavior change stage). Participants from the USA (N = 1614), the UK (N = 1664), and the Netherlands (N = 1967) completed an online survey that measured their WTP for animal- and plant-based pairs of diverse frequently-consumed products. Segments were identified using a k-means algorithm on standardized WTPΔ scores across countries. Two clusters emerged: Animal-positive consumers (22.6%) had a higher relative valuation of animal-based products (MWTPΔ = 1.49, SD = 0.83), while plant-positive consumers (77.4%) reported a higher WTP for plant-based alternatives (MWTPΔ = -0.44, SD = 0.50). The animal-positive cluster expressed a lower behavior change stage, lower intention to consume plant-based alternatives, greater perceived barriers for reducing animal-based intake, and a larger representation of older, male, and rurally-situated consumers. While it remains to be empirically tested, our findings allude to the potential value of implementing both animal-based taxes and plant-based subsidies in a tailored manner aligned with cluster profiles.

Support surges for UK ban on low welfare imports
It is rare to encounter such overwhelming support for anything, let alone a government policy. But our research has uncovered just that. The public agrees. Farmers agree. And animal advocates agree. Lower-welfare animal product imports have no place in the UK.

Shifting horizons: Significant life events and pro-environmental behaviour change in early adulthood
Young people’s daily routines are especially malleable during significant life events, offering opportunities for pro-environmental behaviour (PEB) change. We investigated how PEBs shifted during two Moments of Change (MoCs), an exogenous disruption (COVID-19) and a biographical transition (starting university). We also looked at whether values and attitudes explained these shifts. We conducted two longitudinal studies with 16–24-year-olds. Study 1 (exogenous MoC) tracked behaviour across three waves during 2020 (n = 146) using multilevel latent growth models. Study 2 (biographical MoC) (n = 256) used paired-samples t-tests examining change across two time points, i.e., pre and post the start of university. Both studies used path-analytic structural equation models to test a values – attitudes – behaviour pathway and regressions to examine the self-activation hypothesis. In Study 1, we found positive changes to food waste and the consumption of animal products, and a negative change in environmental activism and active travel. In Study 2, we found positive changes in domestic PEBs, active travel, and the consumption of animal products, and negative changes in environmental activism and ethical consumption. Self-transcendence values positively predicted activism (Study 1) and domestic PEBs (Study 2) and related to lower animal-product consumption in both studies, while environmental attitudes mediated the link between self-transcendence and consumption only in Study 2. These findings suggest that targeted interventions timed to MoCs can leverage values and attitudes to support lower-impact diets and home practices. Structurally constrained domains (e.g., activism opportunities, infrastructure-dependent travel) may require contextual changes in tandem with MoCs to yield benefits to PEBs. Our study is one of the first to look at COVID-19 as a MoC and one of the first to examine the transition from school to university and its effects on multiple PEBs. Some limitations include reliance on self-report measures with retrospective baselines and short follow-up periods.

Social change as a lifestyle: Identifying actions and practices of vegan activism among young adults
While classical models of social-movement research focus on protests and collective events, recent work has shifted toward an individualized approach to collective action within political participation and activism. Drawing on 73 in-depth qualitative interviews with 40 young vegans in Santiago, Chile, we examine how participants themselves define and enact vegan activism in everyday life. Our results reveal that veganism transcends dietary choice, encompassing professional engagement, online content creation, and even cooking and commensality as deliberate activist practices. These lifestyle-based practices coexist with organized collective actions—like marches and NGO initiatives—to forge a hybrid model of political participation blending individual agency and collective coordination. By integrating these findings into existing theories of lifestyle political activism, we offer a more nuanced framework for understanding political participation. First, we reconceptualize vegan activism as simultaneously a lifestyle movement and a social movement. Second, we introduce a typology that classifies activist actions and practices along the axes of individual versus collective action and interpersonal versus public impact. Third, we uncover underexplored domains—culinary-based actions and professional engagement—that extend current theories of everyday political activism. These findings not only advance theory but also offer practical insights for vegan and environmental activists—such as food-based interventions and digital outreach strategies—to enhance the impact and reach of their practices. By foregrounding activists’ own definitions and experiences in a Global South context, this study demonstrates the value of situated analyses for reconceptualizing political participation and broadening core theoretical frameworks.

What is veganism? Sociocultural resistance to structural speciesism and spatial reconfiguration
Veganism is a sociocultural-identity, ethical-political, and spatial movement that confronts structural speciesism and the colonial continuities of the Plantationocene. Being vegan goes beyond renouncing what one eats or wears; it is a coherent and conscious choice about how one lives and with whom one chooses to share the world. This phenomenon is understood through a theoretical-conceptual anthropological approach, which examines three planes of spatialization: everyday practices that reorganize lived space and consumption circuits; intentional actions, such as occupations and activism, that establish zones of contestation; and digital territorialities that dispute narratives and reconfigure symbolic space. The articulation of these planes produces vegan places, non-places of animal exploitation, Foucault’s heterotopias, and Bey’s Temporary Autonomous Zones, connected by counter-cartographies that reveal human peripheries and spaces of animal exploitation. The synthesis of Harvey and Lefebvre’s spatial theories demonstrates that such zones reterritorialize flows of food, labor, and affection, expanding socio-environmental and interspecies justice. Four ethical axes are proposed: justice for sentient beings; rejection of animal exploitation; recognition of ecological interdependence; and moralization of consumption and habitus. The conclusion is that veganism acts as a transformative cultural force, reorganizing sociocultural and spatial dynamics and inspiring new ethnographic investigations into the impacts of different spatialization plans on the local economy and sociability.
