Consumers’ attachment to meat: Association between sensory properties and preferences for plant-based meat alternatives
Abstract:
For the sake of both the environment and human health, it is necessary to reduce meat consumption. However, increased consumer adoption of plant-based meat alternatives (PBMAs) will only occur when such products are attractive. PBMAs with meat-like sensory attributes and those that can be cooked similarly to meat are known to be preferred, but the preference for meat-likeness varies depending on the consumer’s attitude towards meat. This study determined the relationship between consumers’ level of meat attachment (MA) on their sensory perceptions…

Consumers’ perception of novel foods and the impact of heuristics and biases: A systematic review
Abstract:
According to the definition adopted in the European Union, novel foods are foods that were not consumed to a significant degree within the Union before May 15, 1997. This includes cultivated meat and insects. Novel foods are meant to play a critical role in the transition towards sustainable food systems. However, their success depends on whether and to what extent they will be incorporated into the diets at the population level. This review investigates consumers’ perception of novel food products by narratively synthesising results on the influence of heuristics…

Cultivating curiosity: Consumer responses to ethical and product benefits in cultured foods
Abstract:
Cultured foods have the potential to profoundly transform the food industry. However, most current research focuses on cultured meat, neglecting other cultured products and begging the question of whether different promotional approaches are suited for certain types of cultured food products than others. To bridge this knowledge gap, we carried out two studies to explore how product type (cultured meat vs. cultured fruit) and benefit type (ethical vs. product attributes such as sensory and nutritional advantages) interact in determining consumers’ willingness to try the products.

Disruptive potential of microalgae proteins: Shaping the future of the food industry
Abstract:
The world population is expected to reach 9.8 billion by 2050 according to a report by the United Nations. The global demand for alternative proteins from different sources, such as microalgae, mycoproteins, insects, cell-based, cultured meat, meat substitutes, dairy alternatives, and fungi-based proteins, is projected to reach USD 290 billion by 2035. Due to their similar characteristics, offered at a relatively more affordable cost than animal proteins, alternative plant-based proteins are experiencing significant global demand. In recent years, industrial production…

Does the advertising of plant‐based burgers attract meat consumers? The influence of new product advertising on consumer responses
Abstract:
The “meat” marketing of new plant-based burgers distinguished them from traditional vegan burgers, yet it is still unknown if and to what extent this advertising appeals to meat consumers. We employ a novel digital advertisement dataset from Nielsen Ad Intel to investigate the market entry and advertising patterns of the Impossible Burger, one of the leading brands in the plant-based meat market. By merging weekly ad views at the DMA market level with Nielsen Homescan Panel, we find that prior purchases of meat burgers reduce the likelihood of consumers…

Examining muslims’ opinions toward cultured meat in singapore: the influence of presumed media influence and halal consciousness
Abstract:
This study examines how halal consciousness acts as a precursor to the influence of presumed media influence model to explain Muslims’ views (i.e., attitudes and behavioral intentions) toward cultured meat. A survey of 658 Muslim Singaporeans found that halal consciousness positively correlated with Muslims’ attention to media messages on the benefits of cultured meat, which subsequently shaped their presumed attention to these messages by family members, friends, and social media influencers. Presumed attention from family members and social media influencers…

Too anthropomorphized to keep distance: The role of social psychological distance on meat inclinations
Abstract:
Keeping a distance from food animals helps alleviate moral conflicts associated with meat consumption. Prior research on the ‘meat paradox’ has shown that physical distance from animals reduces negative emotional responses when consuming meat. However, even with physical distance, the presence of animals in meat advertisements and packaging can establish psychological contact. The impact of psychological distance on meat consumption and purchase inclinations has not been well explored. Through four experiments, we discovered that…

Finding biomarkers of experience in animals
Abstract:
At a time when there is a growing public interest in animal welfare, it is critical to have objective means to assess the way that an animal experiences a situation. Objectivity is critical to ensure appropriate animal welfare outcomes. Existing behavioural, physiological, and neurobiological indicators that are used to assess animal welfare can verify the absence of extremely negative outcomes. But welfare is more than an absence of negative outcomes and an appropriate indicator…

Irish farmers’ engagement with dairy calf welfare: An exploratory analysis
Abstract:
Dairycalf welfare is receiving increasing public attention. To ensure optimal practices, farmers need to engage and be mindful of unethical behavior. However, avoiding information on animal welfare is common and often driven by willful ignorance. We conduct an exploratory analysis on survey data from 546 Irish dairy farmers. We investigate farmers’ choice to view a picture of transported dairy calves and find that over 20 per cent of farmers prefer to remain in a state of ignorance. Higher self-reported calf mortality and education increase the odds of viewing the picture while being a female decreases them.

Space use of free-range laying hens on two differently structured outdoor ranges
Abstract:
Consumers’ awareness of animal welfare in farm animal husbandry – including laying hen systems – increased in the last few decades. As a result, more and more farmers in Austria changed from barn systems to free-range husbandry. However, only giving laying hens access to an unstructured outdoor area might cause poor use of major parts of the outdoor range. Since the ancestor of domestic chicken – the red junglefowl – inhabits dense jungle forests with manifold ground vegetation, the structural design of an outdoor area might also be of high importance for laying hens.

Loss of a grooming enrichment impacts physical, behavioural, and physiological measures of welfare in grazing beef cattle
Abstract:
Pasture-based beef cattle are raised in a range of production environments. Some paddocks may contain trees and other objects that allow for grooming, hence being naturally enriching, whilst others may be barren without these opportunities. Additionally, it is not uncommon for cattle to move between these enriched and barren environments as part of routine management. While the benefits of enrichment are well studied, how this ‘enrichment loss’ impacts cattle welfare as access to stimuli is removed is unknown.

Humane slaughter in Mediterranean sea bass and bream aquaculture: Farm characteristics, stakeholder views, and policy implications
Abstract:
In many countries, increasing concern for animal welfare is driving retailer commitments and government legislation that aim to improve the lives of farmed fish. One aspect of fish welfare involves stunning fish prior to slaughter. The feasibility of stunning depends on the species of fish and physical farm characteristics. In this article, we provide an overview of stunning before slaughter in European sea bass and sea bream aquaculture, one of the largest finfish farming industries in the developed world that does not yet stun most of its production.

Structural enrichment promotes natural behaviour and welfare of captive gilthead seabream broodstock
Abstract:
The intensification of aquaculture practices in the last decade can compromise the welfare of farmed fish. However, one strategy to be considered to improve the welfare of captive fish is the implementation of structural enrichment in the rearing environment. The behavioural and physiological effects of suspended ropes inside rearing tanks were experimentally assessed on gilthead seabream (Sparus aurata) breeders, evaluating the potential use of such structures in production units.

Sustainability benefits of transitioning from current diets to plant-based alternatives or whole-food diets in Sweden
Abstract:
Plant-based alternatives (PBAs) are increasingly becoming part of diets. Here, we investigate the environmental, nutritional, and economic implications of replacing animal-source foods (ASFs) with PBAs or whole foods (WFs) in the Swedish diet. Utilising two functional units (mass and energy), we model vegan, vegetarian, and flexitarian scenarios, each based on PBAs or WFs. Our results demonstrate that PBA-rich diets substantially reduce greenhouse gas emissions (30–52%), land use (20–45%), and freshwater use (14–27%), with the vegan diet showing…

Individual differences in effective animal advocacy: moderating effects of gender identity and speciesism
Abstract:
The present research examined whether personality and individual differences have practical implications for effective animal advocacy (i.e., how effective an animal advocacy message is) by exploring whether individual differences in gender identity, social dominance orientation, and speciesism moderate the effects of advocacy. An online study was conducted employing an experimental design (advocacy vs. control condition). Four hundred and ninety-five participants (120 men, 375 women) watched either an advocacy video showing chickens suffering…

Nudging plant-based alternatives to meat and dairy in a real-life online supermarket: A randomized controlled trial
Abstract:
A shift from predominantly animal-based to plant-based consumption can benefit both planetary and public health. Nudging may help to promote such a shift. This study investigated nudge effects on plant-based alternatives to meat and dairy in an online supermarket. We conducted a two-arm, parallel-group, randomized controlled real-life online supermarket trial. Each customer transaction was randomized to a control arm (regular online supermarket) or an intervention arm…

Food systems
Dietary shifts and the need for increased sustainability approaches in the global aquaculture seafood system
Abstract:
Recent shifts in the global dietary preferences have indicated the fast-growing choice for plant-based, or meat-reduced diets. Among the motivations for such choices, which are increasingly advocated by nations and environmental institutions, is the major concern with global environmental sustainability and impacts of food production systems. Incontestably, the animal food source industry is extremely diverse, and seafood production through the aquaculture value chain remains unfamiliar to key stakeholders possibly leading to an uncomprehensive…

Estimating global numbers of fishes caught from the wild annually from 2000 to 2019
Abstract:
Finfishes are caught from the wild for food, feed (often in the form of fishmeal and oil) and bait. According to the Food and Agriculture Organisation of the United Nations (FAO), between 74 and 83 million tonnes (averaging 77 million tonnes) were caught annually in 2000–2019. Although fishes are now widely recognised as sentient beings, capture is still quantified as biomass rather than number of individuals (in contrast to wild-caught marine mammals and crocodiles; and farmed mammals and birds). Here, we estimate global numbers of wild-caught finfishes using FAO capture production (landing) tonnages (2000–2019 data) and…

Price above all else: an analysis of expert opinion on the priority actions to scale up production and consumption of plant-based meat in Brazil
Abstract:
Introduction: Plant-based meats (PBM) are an emerging set of food technologies that could reduce the environmental impacts of food systems by mitigating consumer demand for animal products. However, scaling up the production and consumption of plant-based meats requires overcoming multiple technological, regulatory, political, and market barriers. An evidence-based prioritization of needs and actions may help actors (e.g., investors, funders, policymakers) who wish…

Investigating the impact of consumer environmental consciousness on food supply chain: The case of plant-based meat alternatives
Abstract:
With plant-based meat increasing in popularity, this study intends to analyze the challenges of popularizing plant-based meat alternatives (PBMAs) and investigate the incentives to enhance future consumption. We investigate a PBMAs producer’s distribution channel selection strategies of direct-sell-to-consumer (DSTC) and indirect-sell-to-consumer (Non-DSTC), as well as the decisions for wholesale price, product eco-friendly level and research and development (R&D) investment on sustainable food products. We first examine global meat consumption trends…

Human-animal relations
Humans and farm animals in documentary film narratives: A romantic perspective on the problem of capitalist meat production
Abstract:
The purpose of this study was to examine the role of Romantic notions in understanding contemporary human–animal relations. I examined how three documentaries dealing with the problem of farm-animal exploitation construct the relationship between farmers and meat producers on the one hand and farm animals on the other. Using the method of multimodal critical discourse analysis, I examined audiovisual and linguistic levels of documentaries. I argue that documentary narratives have a dual function in exploring these relationships.

Josh Milburn’s just fodder: the ethics of feeding animals
Abstract:
In his book Just Fodder, Josh Milburn combines insights from animal ethics, the philosophy of food, and food ethics to discuss the ethical issues concerning humans feeding nonhuman animals. His ethical framework relies on negative, interest-based rights not to be harmed and killed, which sentient animals have towards moral agents. He extends these rights with relationship-based, positive duties that humans have towards certain nonhuman animals if humans are responsible for them being dependent on humans. Milburn’s exploration of different human-animal relations makes further distinctions than Donaldson…

Research And Data As Tools In Advocates’ Decision-Making
Abstract:
While all animal advocacy organizations have clear mission statements, priorities, and tactics that guide both day-to-day activities and big-picture planning, groups vary in how they use data in their decision-making. There is a growing interest in the animal advocacy ecosystem across many focal areas in taking evidence-based actions and having a research foundation for statements and positions. However, some organizations hypothesize that research and data might not be seen as relevant or able to be integrated with these foundational commitments.

“We forgot about the donkeys!” An institutional analysis of the shift in animal welfare from direct implementation towards advocacy-based programming
Abstract:
Shifts from direct implementation to advocacy-based programming have been documented across many non-governmental organisation (NGO) sectors, including animal welfare. Semi-structured interviews with 32 staff from different positions within animal welfare NGOs explored recent programming changes. Maintaining a balance between direct implementation and advocacy-based activities emerged as a strong theme. The findings suggest that risks are associated…

From predictive analytics to emotional recognition - The evolving landscape of cognitive computing in animal welfare
Abstract:
This paper explores the fusion of data science and cognitive techniques in deciphering the behaviors and emotions of farm animals. The focus is on the strategic application of digital imaging and artificial intelligence to discern subtle behavioral patterns and micro-expressions in livestock, offering a predictive window into their emotional states. The significance of acoustic vocalization analysis in interpreting complex communicative signals and emotional subtleties is highlighted. The work extends to cognitive evaluations, such as mirror tests…

How we calculate animal savings through replacing ingredients or meals
Abstract:
Since eating patterns around the world vary substantially, the impact of changing dietary behaviours, meal composition, or ingredients is also likely to vary between countries, regions, and continents. The per-capita consumption of meat might be quite similar in two different regions, but one region might consume more pork while the other consumes more poultry – thus a meat-reduction intervention might spare more animals in the latter country. Furthermore, there are other differences that have an impact on eating patterns: for example, the yield per animal (meat, milk, eggs) might be quite different in different regions, again affecting…

Towards an epistemology of ‘speciesist ignorance’
Abstract:
The literature on the epistemology of ignorance already discusses how certain forms of discrimination, such as racism and sexism, are perpetuated by the ignorance of individuals and groups. However, little attention has been given to how speciesism—a form of discrimination on the basis of species membership—is sustained through ignorance. Of the few animal ethicists who explicitly discuss ignorance, none have related this concept to speciesism as a form of discrimination. However, it is crucial to explore this connection, I argue, as ignorance is both an integral part of the injustice done to animals as well as an obstacle to improving their treatment.

Animal welfare as the basis of One Health: A UN convention on animal welfare, health, and protection poses a realistic solution to improved animal welfare and human health
Abstract:
Animal welfare is closely linked to animal health and human welfare and health, as the World Organisation for Animal Health (WOAH) emphasizes in its Global Animal Welfare Strategy of 2017. As a result of recent pandemics, the Food and Agriculture Organization of the United Nations (FAO), the UN Environment Programme (UNEP), the World Health Organization (WHO), and the WOAH have created the One Health High Level Expert Panel (OHHLEP), committed to animal health and human health in the One Health Joint Plan of Action (2022–2026) and pledged…

Policy mix for the sustainable protein transition in Austria - Addressing repercussions of regime shifts as a prerequisite for acceleration
Abstract:
The sustainable protein transition within a broader food system transition currently lacks a consistent and coherent policy approach. Policies related to protein production are not aligned with consumption-based policies and are embedded in different jurisdictions. Exemplified by the case of Austria, this study aims to assess the current policy mix and explore how it could be designed to support a sustainable protein transition. We apply the six policy intervention points framework to identify gaps and complement…

Slaying the swiss unicorn of animal dignity
Abstract:
In this article, we describe and analyse the Swiss legislation relating to animal dignity. We conclude that previous criticisms of the law do not go far enough: far from protecting animal dignity, the Swiss law not only undermines such dignity but itself serves as a means to ensure that animals can be used merely as a means, and not treated with respect. As such, the Swiss Animal Welfare Act is deeply unethical and undermines the constitutional requirement to treat animals with dignity.

Applying the theory of behavioral choice to plant-based dietary intentions
Abstract:
Improving understanding of the intention to choose plant-based food is an important element of climate change mitigation. A cross-sectional survey of 454 North American adults was used to predict their dietary-change intentions from the theory of planned behavior (TPB) and the more-recently proposed theory of behavioral choice (TBC). The TPB accounted for 65 percent of the variance in intentions and the TBC accounted for a significantly greater (80 percent) proportion of variance. The strongest predictors of intention were the TBC’s sense of obligation…

Comparison of personality traits of two anti‐oppression groups: Vegans and anarchists
Abstract:
Veganism and anarchism are burgeoning worldwide, yet very few studies have examined the psychological characteristics of people belonging to these two anti-oppression groups. The present study investigated whether vegans and anarchists, on the one hand, and activists and non-activists belonging to these two groups, on the other hand, exhibit distinct personality profiles. To this end, a sample of 180 adults who self-identify as vegans or anarchists completed an online socio-demographic questionnaire, the HEXACO Personality Inventory, and the Dark Triad Dirty Dozen.

Factors shaping the adoption of sustainable vegan diets
Abstract:
The quality and choices of food contribute significantly to human well-being and support the development of healthy communities worldwide. Despite being the world’s largest vegetarian nation, India predominantly follows lacto-vegetarianism, allowing dairy consumption and creating a distinct dietary landscape shaped by influences from religious, social, and cultural beliefs. This complexity, where dairy and cultural-religious factors play pivotal roles, makes India a compelling and unique case for understanding the intricacies of adopting vegan dietary preferences. In the present study, an integrated model derived from the health belief…

Vegan labor: the intensification of family foodwork at the intersection of dietary and gender norms
Abstract:
Drawing from a case study of child veganism in Switzerland, I bring together parenting culture studies and food studies to ask how veganism relates to the ideology of intensive mothering. Describing five kinds of “vegan labor” – extra foodwork that vegan parents attributed to their vegan lifestyle –, I find that adopting an alternative diet intensifies parental commitment in a gendered way. Discussing these findings against the backdrop of the Swiss culture of nutrition and gender regime, I underline how examining alternative diets can further our understanding of parenting culture, gender roles, and foodwork. Intensive mothering…
