Are plant-based meat analogues fulfilling their potentials? An Australian perspective
Abstract:
The plant-based meat analogue (PBMA) market in Australia is growing, as it is globally, based on the potential of the products’ healthiness and sustainability. The potential of current commercially available PBMAs in Australia is assessed based on healthiness and sustainability followed by a comparison of the plant proteins which have demonstrated desirable functionality with those used in commercially available PBMAs. Robust evidence supports the sustainability claims of PBMAs over meat products. Regarding healthiness, on a macro scale, there is nutritional equivalence; however, on a micro scale, most commercial PBMAs lack essential minerals and vitamins (such as iron and vitamin B12).

A taste of cell-cultured meat: A scoping review
Abstract:
Cell-cultured meat (CM) is a novel meat product grown in vitro from animal cells, widely framed as equivalent to conventional meat but presented as produced in a more sustainable way. Despite its limited availability for human consumption, consumer acceptance of CM (e.g., willingness to purchase and consume) has been extensively investigated. A key but under-investigated assumption of these studies is that CM’s sensory qualities are comparable to conventional, equivalent meat products. Therefore, the current review aims to clarify what is actually known about the sensory characteristics of CM and their potential impact on consumer acceptance. To this end, a structured scoping review of existing…

Awareness and acceptance of informed and professional consumers of Jammu and Kashmir about cultured meat
Abstract:
The present study aimed at evaluating the awareness and acceptance of informed and professional consumers towards cultured meat. A survey-based study was conducted using 295 food science scholars and 105 veterinary professionals as respondents. The study was designed to decipher whether knowledge about meat and food production affects the acceptance of cultured meat. The majority of the respondents were male (54 %), ate meat (73 %) and showed preferences for red meat (65 %). The majority of the respondents were not sure (neither agreed nor disagreed) that cultured meat is healthy (69 %) and were not sure about its long-term effects on human health (73 %). The majority agreed that it does not seem…

Consumer cognition and attitude towards artificial meat in China
Abstract:
This study focuses on Chinese consumers’ cognition and attitude towards artificial meat, including cultured meat and plant-based meat. The attitude is measured by three aspects: willingness to accept (WTA), willingness to taste (WTT), and willingness to buy (WTB). The results indicate that consumers’ attitude towards plant-based meat is more favorable than that towards cultured meat. Consumers’ attitude towards artificial meat is positively correlated with their cognition of artificial meat, dietary knowledge, and information intervention. Compared to those who have not heard about artificial meat, consumers who are aware of it have 8%-36% higher probabilities of accepting, tasting, and buying…

Consumer evaluation of plant-based ground beef alternatives in real-world eating scenarios
Abstract:
The objective of this study was to evaluate the palatability of 3 plant-based ground beef alternatives (GBA) in comparison to ground beef under real-world hamburger and taco scenarios. The 3 plant-based GBA alternatives used represented a modern GBA sold at retail (RGBA), a modern GBA sold in foodservice (FGBA), and a traditional soy-based GBA (TGBA). Additionally, 80% lean ground beef was evaluated. Consumers (N=240; n=120 per panel type) evaluated samples for juiciness, tenderness, texture, beef flavor, overall flavor, overall liking, purchase intent,and purchase price and rated traits as either acceptable or unacceptable. For hamburger panels, consumers were served samples on buns…

Consumer perception and preference toward plant-based meat alternatives: Bibliometric trends and policy implications
Abstract:
Background
Plant-based meat alternatives (PBMAs) could be a promising source for protein intake and reduce the dependence on unsustainable meat production and consumption. However, the concern about the production and processing of PBMAs persists, besides the consumers’ attitude. The opinion about scientific evidence among stakeholders on the promotion of PBMAs differ. This study presents the trends in consumer perception and preference toward PBMAs and suggests a facilitating policy framework for promoting consumption.
Scope and approach

Critical review of cultivated meat from a Nordic perspective
Abstract:
Background
Cultivated meat is a novel technology with the potential to partly substitute conventional meat in the future. Production of cultivated meat is based on biotechnology for tissue engineering, up-scaling of cell cultures and stem-cell differentiation, providing the basis for large-scale proliferation of the parent cell and subsequent differentiation into primitive skeletal muscle structures known from conventional meat. Development of cultivated meat is considered a socio-technological challenge including a variety of technical, sustainability, ethical, and consumer acceptance issues.

Decoding demand: The appetite for alternative proteins in Southeast Asia
Decoding the meaning of alternative proteins: Connotations and music-matching
Abstract:
Alternative proteins have recently received significant attention from both academia and industry. Given the reported lower willingness of consumers to accept these alternative protein sources, it is crucial to gain insights into consumers’ perceptions of them. Study 1, based on the theory of the meaning of objects and concepts, unveiled the connotative meaning (evaluation, potency, activity) associated with five alternative proteins (insects, cultured meat, mycoprotein, algae, and plant-based proteins). Animal-based sources, such as insects and cultured meat, received lower ratings in evaluation but scored higher in potency/activity.

Future food: Can cultivated meat save our planet?
Abstract:
Think about what humans will eat in the future. Could you imagine eating meat produced without the extensive farming of animals? This scenario is not as unlikely as you might think. To protect our planet, we must reduce the irreversible damage we are doing to the environment. Eating less meat is a major part of this, because the way we produce most meat today has a tremendous impact on the environment. Plant-based meat alternatives are already available in stores, but it is hard to imitate the taste and texture of meat if no animals are involved. Therefore, scientists have been working on an alternative, called cultivated meat…

Implications of food culture and practice on the acceptance of alternative meat
Abstract:
To investigate the influence of food culture on the acceptability of meat substitutes, in 2023 we conducted a questionnaire survey on men and women aged 18–69 years (N = 1681) in Japan, a country with a food culture that regards soya as a meat substitute, focusing on ‘meaning’ in the theory of practice. Analysis of three groups—a flexible group who accept foods processed from soya as meat, a strict group who do not accept such foods as meat, and an intermediate group—showed that the flexible group tended to be more positive about the consumption of meat substitutes than the other groups. However, the flexible group…

Increasing the appeal of plant-based foods through describing the consumption experience: A data-driven procedure
Abstract:
Global meat consumption is a significant contributor to the high levels of greenhouse gases currently being emitted, and shifting diets to plant-based products is an effective way of limiting further climate change. However, plant-based products are often thought to be less tasty than their meat-based counterparts and perceived as unappealing by omnivorous consumers. Therefore, we present a systematic procedure for establishing and testing whether describing plant-based dishes in terms of the rewarding aspects of consumption has the potential to make them more appealing and increase intentions to select and consume them…

Modelling the mass consumption potential of Plant Based Meat: Evidence from an emerging economy
Abstract:
The rising demand for plant-based meat (PBM) has the potential to minimize environmental degradation and save the lives of numerous animals. Furthermore, the intention to consume eco-friendly products triggers people to consume PBM. However, it is essential to understand the factors that influence consumer intentions and actual PBM consumption to enhance its adoption. By incorporating the Theory of Consumption Value, this study examines the impact of health consciousness, health motivation, personal innovativeness, perceived critical mass, perceived cost, and perceived product value on the intention to consume PBM.

Plant-based alternatives need not be inferior: Findings from a sensory and consumer research case study with cream cheese
Abstract:
Reliance on animal foods must be reduced to improve planetary and human well-being. This research studied plant-based cheese alternatives (PBCA) relative to dairy cheese in a consumer taste test with 157 consumers in New Zealand. A case study approach used cream cheese (commercially available) as the focal product category (2 PBCA, 2 dairy) and implemented a multi-response paradigm (hedonic, sensory, emotional, conceptual, situational). “Beyond liking” insights were established, including drivers of liking (sensory, non-sensory) and sensory drivers of non-sensory product associations. Two consumer segments were identified…

Producing knowledge about the sustainability and nutritional values of plant and animal-based beef: Funding, metrics, geographies and gaps
Abstract:
One of the technological responses to concern about the healthiness and sustainability of red meat consumption as well as growing global food insecurity has been the development of plant-based meats. While still niche industries, plant-based meats are increasing in diversity and visibility and are often accompanied by scientific claims about their potential contribution to sustainability, health and nutrition. In this paper we analyse these claims from the perspective of critical metrology, looking not only at the state of knowledge about plant- and animal-based beef but also how knowledge is being produced. Such research is vital in understanding…

Scalable processes for culturing meat using edible scaffolds
Abstract:
There is increasing consumer demand for alternative animal protein products that are delicious and sustainably produced to address concerns about the impacts of mass-produced meat on human and planetary health. Cultured meat has the potential to provide a source of nutritious dietary protein that both is palatable and has reduced environmental impact. However, strategies to support the production of cultured meats at the scale required for food consumption will be critical. In this review, we discuss the current challenges and opportunities of using edible scaffolds for scaling up the production of cultured meat.

Technical, commercial, and regulatory challenges of cellular agriculture for seafood production
Abstract:
Background
Cultivated seafood is a promising novel approach to global food security and sustainability, as current seafood production methods may not meet the needs of increasing world population and rising seafood consumption. Hence, cell-based seafood is an important part of modern food innovation to supplement current seafood production. Life cycle assessments (LCAs) of the commercial and environmental impact of cultivated meat highlight the importance of low-cost culture media without serum and antibiotics to commercial feasibility

The consumer acceptance of novel foods on potential markets using an Extended Behavior Model
Abstract:
This research aims to determine the purchase intention of cultured meat using an expanded planned behavior theory approach. The development of science has encouraged scientists to look for the latest innovations known as novel foods with the aim of alternative food in the future. Research on consumer acceptance of cultured meat has been carried out in many developed countries by looking at the potential for various consumer acceptance of cultured meat. Indonesia, as one of the potential markets for novel foods, is necessary to also look at the potential for consumer acceptance of novel foods, especially on cultured meat.

Understanding consumer attitude toward the name framings of cultured meat: Evidence from China
Abstract:
The naming and labeling of products can affect consumer attitudes and subsequent behavior, particularly in the case of new food products in the market. The present study explores the effects of name framing on consumer attitudes towards cultured meat (CM), which is currently in the early stages of development. With a sample of 1532 Chinese consumers, we integrated several pathways to explain the name-framing effect by examining three different terms (“cultured,” “artificial,” and “cell-based”) for CM. Results indicate that “cultured meat” and “cell-based meat” are more appealing than “artificial meat.” Name framings of CM affect consumers’ perception of benefits more than that of risks.

What do we know about consumers’ attitudes towards cultured meat? A scoping review
Abstract:
Scientific breakthroughs in lowering cultured meat’s production cost have ignited the hope of developing a global cultured meat industry. This has resulted in a surge in consumer psychology studies on cultured meat, as researchers have sought to determine the antecedents of cultured meat’s acceptance and consequently acquire insights into the demand feasibility of the envisaged industry. However, the literature is fragmented; hence, this study aims to summarize the state of knowledge and consolidate the findings of this literature. A secondary purpose was to reflect on the depth of evidence, highlight the major findings and identify gaps/trends in knowledge. The study noted growing…

Cross-sectional survey of public perception of commercial greyhound racing in New Zealand
Abstract:
The commercial greyhound racing industry in New Zealand is struggling with an eroding social license and ‘on-notice’ status. Multiple independent reviews of the industry have identified ongoing issues of animal welfare during and between races, euthanasia decisions, poor data tracking, a lack of transparency and problems with rehoming dogs, resulting in New Zealand animal advocacy agencies and the general public questioning the continuation of greyhound racing. The current paper assessed the New Zealand public’s awareness and familiarity with commercial greyhound racing, identified current levels of public support or opposition for racing, and provided context in terms of engagement…

End of the cage age? A study on the impacts of the transition from cages on the EU laying hen sector
Abstract:
This paper’s main objective is to assess the impacts of the ban on cages for housing laying hens, planned by the European Commission to raise animal welfare standards beyond the level set in the current legislation. The farm-level economic assessments of the ban were carried out in three stages: farm surveys and expert consultations, farm-level analyses, and aggregation to the EU-27 egg production sector. Four scenarios were constructed. All financial estimates were conducted with fixed prices from the year 2021 for which the reference scenario was built. Alternative hen-housing systems were barn (Voliera), free range, and organic.

Farm animal welfare during transport and at the slaughterhouse: Perceptions of slaughterhouse employees, livestock drivers, and veterinarians
Abstract:
Animal welfare is a multidimensional concept that includes several physical and psychological parameters of the animal. The aim of this study was to assess animal welfare during transportation and in Slovenian beef, pork, and poultry slaughterhouses. A questionnaire was used for this study. Several parameters of animal welfare were rated on a 5-point scale, such as health status, animal behavior, lairage or transport vehicle conditions, and driver regulation compliance. The scale was also used for the second part of the study. This consisted of two studies: (1) self-assessment by slaughterhouse employees and livestock transport drivers and (2) animal welfare observational assessment performed by two veterinarians.

Hybrid governance and welfare standards for broiler chickens raised for human consumption
Abstract:
This article examines the welfare standards that govern the lives of chickens raised for meat in Australia and the United Kingdom. While ‘meat chickens’ are subject to a wide range of welfare interventions, we focus on the development and implications of the ‘private’ standards which are the most significant determinants of meat chicken welfare in these jurisdictions: the RSPCA Approved Farming Scheme in Australia and the Red Tractor Chicken Assurance Scheme in the United Kingdom. While the jurisdictions appear to have a similar regime that favours private regulation, differences in the origins and governance of these systems can be identified, offering insights into the use of hybrid regulation in areas…

Research Note: Welfare and stress responses of broiler chickens raised in conventional and animal welfare-certified broiler farms
Abstract:
The present study was conducted to assess the animal welfare status of broiler chickens raised in conventional and welfare-certified farms. One conventional farm (30,000 birds/house, 1,488 m2/house, 2 houses) and one animal welfare-certified farm (32,000 birds/house, 1,920 m2/house, 2 houses) were selected to measure productivity, stress responses, and animal welfare indicators in 3 broiler flocks (2 farms/season, n = 6 flocks/farm type) during summer, autumn, and spring. Upon farm visits, body weight, uniformity, and animal welfare indicators (i.e., fecal and feather corticosterone, footpad dermatitis, hock burn, feather dirtiness, and gait score) were measured at 26 d posthatch.

An investigation of meat eating in samples from Australia and Germany: The role of justifications, perceptions, and empathy
Abstract:
Despite concerns about animal welfare, and health and environmental issues associated with eating meat, meat consumption has continued to increase worldwide, including in Australia. One exception to this is Germany, with 2021 meat consumption levels being the lowest in the last 30 years. This pre-registered study investigated socio-cultural variables associated with meat consumption in Germany (n = 399) and Australia (n = 399) in a cross-sectional online survey. Participants reported levels of current and intended meat consumption, and they completed measures of speciesism, motivations to eat meat, empathy, animal farming perceptions, perceived behavioural control (PBC) over meat eating…

How perceptions of meat consumption norms differ across contexts and meat consumer groups
Abstract:
Social norm perceptions are implicit standards describing what is typically done or seen as acceptable and have shown to be important both in sustaining meat consumption as well as facilitating meat reduction. Norm perceptions depend on individual differences and the contexts (e.g., supermarket, restaurant). Yet, evidence how norm perceptions differ within and across individuals is scarce. The primary aim of this study was to investigate how descriptive, injunctive, and personal norms perceptions favouring meat consumption differ across contexts and meat consumer groups. The second aim was to investigate how generic dynamic norm perceptions vary across meat consumer groups.

Climate change and sustainability
Age differences and profiles in pro-environmental behavior and eco-emotions
Abstract:
Previous research suggests that age-related differences in pro-environmental behavior (PEB) and the emotional reactions to climate change could originate from generational as well as aging effects and can be influenced by the opportunities and constraints of life circumstances and resources. The current research aimed to better understand age differences through examining the eco-emotions and PEBs of different age groups, and identifying latent groups differing on these variables. In Sample 1, adults from the general population (n = 4,685) filled out questionnaires assessing eco-anxiety, eco-guilt, and ecological grief and answered 12 questions about their PEBs. In Sample 2 (A)…

In support of framing food identity towards pro-environmental food choices through empirical evidence
Abstract:
The relation between food and identity has not been investigated extensively in environmental research so far. People value food products not only for the material and concrete benefits, but also for what they symbolize to themselves and to the other members of the community. The aim of this study is to detect the predictable significance of eating behavior with identity and to observe how the production process of traditional food can restrict consumer choices towards a more sustainable process. The whole objective is to achieve a deep knowledge regarding the impact of strong food identity on food choices and on the spreading of novel foods for sustainable food consumption among adults.

The impact of consumers’ preferences for domestic food on dietary sustainability
Abstract:
A sustainable dietary transition requires knowledge of the drivers and barriers of dietary choices. We investigate the role of preferences for domestic food, as well as environmental and health concerns, as drivers for the consumption of red and white meat, fish, ready-made plant-based food products and self-identification as some type of meat reducer (flexitarian, vegetarian, or vegan). A survey of 1102 consumers was conducted in Norway with questions about food attitudes, beliefs and preferences regarding health, the environment and domestic food as well as dietary habits and demographics. The results from interval and logistic regression analyses show that stronger preferences…

The politics of red meat consumption and climate change
Abstract:
Red meat production is one of the leading sources of carbon dioxide emission thus reducing meat production and consumption is crucial. Using a sample of American adults (n = 456), the link between right-wing sociopolitical ideologies and (i) attitudes towards red meat; (ii) willingness to reduce red meat consumption; (iii) willingness to pay more for red meat; (iv) belief about the impact of red meat consumption on the environment; and (v) and distrust (versus trust) of authorities was examined. Right-wing ideologies (i.e. right-wing-authoritarianism and social dominance orientation) were associated with more positive attitudes towards red meat, unwillingness to consume…

Dietary change interventions
A diet-related health prompt with the Swiss Food Pyramid as a nudge to reduce meat consumption
Abstract:
High meat consumption in Western societies is a major contributor to climate change, environmental damage, and health costs. One way to reduce meat consumption is through nudges in staff restaurants. Though previous studies have shown that nudges can influence consumer choices, there is a lack of comparative studies of the different types of nudges in the context of staff restaurants. The present study thus aimed to compare, individually and in combination, the effectiveness of a written prompt, a visual prompt (the Swiss Food Pyramid), and a dynamic social norm in encouraging consumers to more frequently choose meatless menu options. A 1 × 8 between-subjects design was applied, and an online choice…

Abstract:
Understanding behaviours driving recent declines in UK meat consumption is essential for achieving the Climate Change Committee’s 20% reduction target by 2030. This study explored trends in meat-eating days, daily meat-eating meal occasions, and portion size of meat from the National Diet and Nutrition Survey (2008/09-2018/19). Meat consumption was assessed using 4-day food diaries. Trends were assessed with Poisson and linear regression models, while decomposition analysis quantified relative contributions to overall reductions. Meat-eating days decreased from 3.27 (0.04) to 3.03 (0.05) (P < 0.001), daily occasions decreased from 1.24 (0.02) to 1.13 (0.03) (P = 0.01), and portion size decreased…

Developing messages to encourage healthy, sustainable dietary substitutions: A qualitative study with US emerging adults
Abstract:
Prior research shows that adopting simple dietary substitutions (e.g., replacing beef with poultry or plant-based entrees) can improve dietary quality and reduce the negative environmental consequences of food production, but little is known about how to encourage people to adopt these substitutions. This study aimed to examine reactions to messages encouraging healthy, sustainable dietary substitutions among emerging adults ages 18–25. We conducted four online focus groups with a diverse sample of US emerging adults (n = 28; 61% female). Focus groups explored emerging adults’ reactions to messages encouraging them to adopt three target dietary substitutions: replacing beef…

Meat reduction meets family reality: Negotiating sustainable diets in households with adolescents
Abstract:
Limited research exists on how the transition towards more sustainable eating takes place at the meso-level of family decision-making, or how children and adolescents engage in and possibly influence the process towards more sustainable diets in families. In this paper, we study how public recommendations that encourage reducing the consumption of meat for the benefit of both health and climate are interpreted, negotiated, and acted upon in Danish families with adolescents (aged 15–20) residing at home. We use novel methodological stimuli, including vignettes and a visual sorting task, embedded in qualitative, in-depth interviews to elicit data on parents’ and adolescents’ everyday meat…

Potential unexpected effects of meat reduction in diet: Could educational attainment influence meat substitution strategies?
Abstract:
Regulation of meat consumption appears to be a relevant public policy to limit diet-related greenhouse gas emissions. However, the real impact of such a policy (e.g., tax) on human health and nutrition remains uncertain, especially for underprivileged individuals. Based on representative data from France, we estimate potential trend differences in the association between meat consumption and nutritional outcomes, such as body mass index (BMI) and unhealthy food intake, according to individual educational attainment. We reveal that among adults with low education levels, reduced meat consumption was significantly associated with a higher BMI, a higher risk of being overweight, and greater intake…

The influence of pricing interventions in food choices on Brazil: An agent-based modelling approach
Abstract:
This study introduces an agent-based model (ABM) to analyse beef consumption trends in Brazil from 2017 to 2020. The ABM assesses the influence of price changes, specifically a rise in beef prices, on consumption behaviours and their diverse impacts across income groups. By integrating demographic and socioeconomic factors, the model replicates beef consumption decisions within Brazil. Findings show that consumer preferences are highly responsive to beef prices, with consumption decreasing as prices increase. A 60 % price increase due to a US$ 42/tCO2e tax could potentially reduce beef consumption by 55 %, cutting livestock-related greenhouse gas emissions by 53 % in Brazil.

“We Chinese just want meat!”: An analysis of Chinese netizens’ reactions to vegetarian advocacy
Abstract:
The shift to a vegetarian diet has multiple benefits, including the promotion of public health, sustainability, and animal welfare. Despite these advantages, vegetarian food choices often provoke controversy, particularly on social media platforms. On International Vegetarian Day 2021, renowned Chinese actress Zhang Jingchu endorsed a documentary titled “Vegetarian” on Weibo, igniting widespread discussion among Chinese netizens. Considering China’s deep cultural and practical roots in vegetarianism, the predominantly negative response to the documentary was surprising. This study employs frame analysis to dissect the portrayal of vegetarianism in the documentary, utilizing topic modeling based…

Can states become wealthier while keeping livestock intensification low? Evidence from india
Abstract:
Rising demand and urbanization have led to the global increase and intensification of livestock production. Intensive production has harmful effects on the environment, public health (due to the emergence of zoonotic diseases), and animal welfare. In order to better understand how livestock production intensifies as countries develop and incomes rise, we examine the relationship between income per capita and intensification of poultry and cattle, using the states of India as a study region. We also replicate this analysis at the district level to test whether the relationship holds at different spatial scales. We identify outlying states and districts to see if there are policies that can keep agriculture production…

Linking production, processing, and consumption of plant-based protein alternatives in Europe
Abstract:
To confront current sustainability challenges, the European Commission aims to transition towards plant-based diets as well as shorter, regionalized value chains. Plant-based meat and dairy alternatives (PBAs) are seen as an important tool in the food system transition, replacing protein from animals with high-protein plant sources such as legumes. However, regionalized PBA value chains require the co-occurrence of legume producers, PBA processors, and consumers, and we lack understanding of the current status and future potential for such value chains in Europe. In this article, we integrate publicly-available datasets with a web-derived inventory of PBA processor locations to map the regional strength…

Moral disengagement in the media discourses on meat and dairy production systems
Abstract:
Meat and dairy production and consumption are the subject of ongoing public debates that touch on various sustainability issues such as biodiversity loss, climate change, animal welfare, and social and health aspects. Despite extensive discussions specifically relating to the environmental impacts of livestock farming in conjunction with animal welfare aspects, there have been no substantial changes in production or consumption patterns. Moreover, the focus of extant research is usually on consumers’ responses to public concerns around livestock production. In this study, we shed light on the discrepancy between the normative discourse and action of relevant value chain actors with the help…

From the backyard to our beds: The spectrum of care, attitudes, relationship types, and welfare in non-commercial chicken care
Abstract:
Non-commercial chickens may be the third most numerous pets in Western countries. Yet, to date, there is limited research into their welfare or the care-taking practices and attitudes of their guardians. Using a quantitative questionnaire, this study investigated non-commercial chicken owners’ care-taking practices, attitudes, and relationship types with their chickens. Additionally, the study investigated barriers to optimizing non-commercial chicken welfare. Specific questions were asked regarding niche care-taking practices, including the use of Suprelorin® implants. With 2000+ responses, this study found variable care-taking practices, yet largely positive attitudes towards chickens…

Data on Swiss citizens preferences and perceptions of agricultural policy
Abstract:
We present representative survey data from 1,542 Swiss citizens. Data were collected across the three largest Swiss language regions (German, French and Italian) in autumn 2022. In the main part of the survey, we collected qualitative and quantitative data on their perception of agricultural policy goals and potential trade-offs. For this, participants were first asked to name the three most important agricultural policy goals. Next, they rated eight pre-defined agricultural policy goals for importance and how much budget they would allocate to the pursuit of each goal if they were to decide about the governmental budget or subsidies. For the goal conflicts, the eight goals were combined into 16 conflicting pairs, where participants…

The politics of red meat consumption and climate change
Abstract:
Red meat production is one of the leading sources of carbon dioxide emission thus reducing meat production and consumption is crucial. Using a sample of American adults (n = 456), the link between right-wing sociopolitical ideologies and (i) attitudes towards red meat; (ii) willingness to reduce red meat consumption; (iii) willingness to pay more for red meat; (iv) belief about the impact of red meat consumption on the environment; and (v) and distrust (versus trust) of authorities was examined. Right-wing ideologies (i.e. right-wing-authoritarianism and social dominance orientation) were associated with more positive attitudes towards red meat, unwillingness to consume less red meat…

All creatures great and small: Faith, spirituality, environmental-animal rights activism and public relations as covenantal stewardship
Abstract:
This study extends the historical record of faith/spirituality-inspired social activism, an under-explored area of advocacy, by examining such campaigning for environmental and animal rights and the worldview and model of public relations that guide such efforts. A combination of qualitative methods was used to obtain data on public relations as conceptualized and practiced including a textual analysis of historical material and institutional media. Throughout history faith/spirituality has inspired Indigenous peoples, governments, and individuals to advocate for environmental and animal rights, playing a central role in the formation and practice of a worldview, caritas, embracing…

Behind vegan label: What’s really in some certified vegan products in Brazil
Abstract:
The number of vegetarians and vegans has been growing worldwide, increasing the food choices available to this public in the market. One way to recognise these products is the presence of a certification label, which guarantees, or should guarantee, the absence of animal ingredients. Despite the growing demand and supply of certified vegan foods, there is no overview on the nutritional composition of these products in Brazil. Thus, a survey was conducted to evaluate the labels of ninety-five certified vegan products from the groups: breads, cookies and crackers, meat substitutes and dairy substitutes. Carbohydrates were the most present macronutrient in all food groups, except for plant-based beverages.

Development of the VEGANScreener, a tool for a quick diet quality assessment among vegans in Europe
Abstract:
Background
The adoption of plant-based and vegan diets is on the rise, paralleling heightened awareness of animal welfare, environmental issues related to climate change, and potential health concerns associated with consumption of animal-source foods. However, plant-based diets are not inherently healthy. Similar to omnivorous diets, they may contain excessive amounts of sugar, sodium, and saturated fats, or lack diversity. Moreover, vegans might be at risk of inadequate intake of certain vitamins and minerals commonly found in foods they avoid, such as riboflavin, niacin…

Narratives of collective action in YouTube’s discourse on veganism
Abstract:
Narratives can be powerful tools for inspiring action on pressing societal issues such as climate change. While social science theories offer frameworks for understanding the narratives that arise within collective movements, these are rarely applied to the vast data available from social media platforms, which play a significant role in shaping public opinion and mobilizing collective action. This gap in the empirical evaluation of online narratives limits our understanding of their relationship with public response. In this study, we focus on plant-based diets as a form of pro-environmental action and employ natural language processing to operationalize a theoretical framework of moral narratives specific to the vegan movement.

Similarities and differences between vegetarians and vegans in motives for meat-free and plant-based diets
Abstract:
Plant-based diets are quickly gaining popularity for their benefits to animal welfare, the environment, and public health. Compared to meat-eaters, meat-abstainers such as vegetarians and vegans are especially motivated by animal rights and the environment. However, little is known about the motivational and psychological factors that distinguish vegetarians from vegans, and what prevents vegetarians to shift towards a fully plant-based diet. In a sample of vegans (n = 335) and vegetarians (n = 182), we investigated a) motives for reducing or quitting meat consumption and b) motives for reducing or quitting animal product (dairy and egg products) consumption, as well as moral psychological…

Theory of food: Unravelling the lifelong impact of childhood dietary habits on adult food preferences across different diet groups
Abstract:
The study investigates the behavioral manifestations of the “Theory of Food” (ToF), a novel theoretical framework centered on the early development of food perceptions. The ToF posits that childhood experiences with food shape cognitive networks influencing adult dietary choices. Stemming from the “Theory of Mind,” the ToF hypothesizes that individuals construct an associative world of food images and representations mirroring the socio-cognitive world shaped by proper theory of mind development. The study, involving 249 healthy adults, employs the Cognitive Food Preference Questionnaire (CFPQ) and the Adult Food Preference Profile (AFPP) to explore the correlation between childhood…
