The Veg∗n Eating Motives Inventory Plus (VEMI+): A measure of health, environment, animal rights, disgust, social, pandemic and zoonotic diseases, and farm workers' rights motives. Appetite 2024; 203:107701. [PMID: 39368781 DOI: 10.1016/j.appet.2024.107701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 09/19/2024] [Accepted: 10/02/2024] [Indexed: 10/07/2024]
Abstract
Health, environmental concern, and animal rights are established motives for reduced meat consumption that can be measured by the Vegetarian Eating Motives Inventory (VEMI). This preregistered study aimed to expand the VEMI to include four less-studied motives: disgust, social, concern about zoonotic diseases and pandemics, and concern for workers' rights. We had three objectives: to combine the seven motives into a comprehensive model, to test if the VEMI+ scales function equivalently across omnivore and vegan groups, and to validate and differentiate these motives against external measures and meat reduction appeals. In samples of 731 omnivores and 731 vegans (total N = 1,462), we found support for the measurement invariance of a seven-factor structure across groups and created a scale with reliable measures for each dimension (ω total between 0.82 and 0.97). Vegans scored higher overall, with substantially higher scores on environmental concern, animal rights, disgust, and zoonotic disease concerns, while omnivores had slightly higher scores on health, social, and workers' rights scales. Scale scores had expected correlations with criterion measures and differentially predicted support for motive-tailored appeals. This study enhances our understanding of dietary motivations and provides a valuable tool for future research.

Abstract
What factors hinder the reduction of meat and/or dairy intake? In this study, we explored the perceived barriers that meat and/or dairy reducers experienced when shifting their diets. We particularly focused on how meat and/or dairy reducers were affected by their beliefs about how omnivores stereotype vegans (i.e., meta-stereotypes), as meta-stereotypes have not been previously explored in this context. Through open-ended questions in an online survey, we explored the experiences and perceived barriers among female meat and/or dairy reducers (n = 272), as well as their perceptions of vegans (i.e., stereotypes and meta-stereotypes), and how these perceptions affected their lived experiences. We analysed the data using reflexive thematic analysis and generated six themes. We highlighted perceptions of cost (Theme 1) and perceptions of health concerns (Theme 2) as the most dominant barriers to the reduction of meat and/or dairy intake. Regarding (meta) stereotypes, participants' perceptions of vegans were shaped by personal experiences and encounters with vegans (Theme 3), and how participants related to vegans was sometimes reflected in the language they used to describe vegans (Theme 4). Participants felt that they, or reducers more generally, were occasionally judged as vegans (Theme 5), which might influence participants' choices and conformity to eating norms (Theme 6). Meta-stereotypes may play a role in polarised dietary group perceptions, and we discuss how they are shaped by social identity processes as well as by aspects of Western food systems.

Abstract
Reducing meat consumption is highly effective for reducing personal carbon emissions, yet most people in Western nations still eat meat. We build on recent research highlighting that group boundaries may impede dietary change by (a) promoting pro-meat norms and (b) prohibiting critical calls for a veg* diet (vegetarian and vegan, i.e., meat-free). Past research relied on self-reports and behavioural measures of engagement, leaving open whether these effects extend to food consumption settings and ad-hoc meal choice. We conducted two pre-registered experiments in which meat-eaters read critical calls to adopt a veg* diet, either by a vegan (outgroup) or a meat-eater (ingroup). In Experiment 2, participants moreover read an article either highlighting a veg* or a meat-eating norm. We then assessed actual (Experiment 1) or hypothetical (Experiment 2) meal choice as dependent variables. As predicted, intergroup criticism (i.e., voiced by veg*s) consistently led to message rejection in comparison to the same criticism voiced by meat eaters, but we did not observe effects on meal choice. Norms neither had a main nor interaction effect on self-reports and behaviour. We discuss potential intermediary processes between engagement with and adoption of a vegan diet and derive evidence-based recommendations for constructive communication across group boundaries.

Abstract
BACKGROUND A shift away from diets high in animal-based foods towards diets high in plant-based foods is desirable considering human health, environmental sustainability, and animal welfare. As the food environment plays a crucial role in shaping consumption patterns, understanding of how changes in the food environment can facilitate plant-based consumption is crucial for the so-called protein transition. The current study aims to garner insight into barriers and facilitators for food outlet managers to take action to stimulate plant-based consumption within a local food environment. METHODS Using a maximum-variation sample approach, we examined possible barriers and facilitators to promote plant-based consumption across different types of food outlets located within a geographically shared food environment (a city in the Netherlands). We conducted in-depth semi-structured interviews among food outlet managers and applied multi-stage thematic analysis to the interview transcripts. RESULTS Most managers underscored the urgency of shifting towards more plant-based diets, and perceived a growing demand for plant-based products. However, three barriers hindered most of them from taking decisive action: Managers' perception of low consumer demand for plant-based food options; fear of consumer resistance when stimulating plant-based food options; and limited behavioral agency to offer attractive plant-based food options. The few managers who made changes, or intend to make changes, are individuals with high intrinsic motivation, knowledge and skills. CONCLUSIONS The present work suggests the key for change towards a food environment stimulating plant-based consumption lies in addressing three (perceived) barriers shared among diverse outlets. These are partly different from barriers for stimulating healthy consumption in general. Furthermore, current changes appear to be driven incidentally by individuals who are motivated and able to stimulate more plant-based purchases among a small targeted group of consumers.

Abstract
The Nutritious Eating with Soul study was a 24-month, randomized behavioral nutrition intervention among African American adults. This present study, which is a secondary analysis of the NEW Soul study, examined changes in dietary acceptability, restraint, disinhibition, and hunger. Participants (n = 159; 79% female, 74% with ≥ college degree, mean age 48.4 y) were randomized to either a soul food vegan (n = 77) or soul food omnivorous (n = 82) diet and participated in a two-year behavioral nutrition intervention. Questionnaires assessing dietary acceptability (Food Acceptability Questionnaire; FAQ) and dietary restraint, disinhibition, and hunger (Three-Factor Eating Questionnaire; TFEQ) were completed at baseline, 3, 6, 12, and 24 months. Mixed models were specified with main effects (group and time) and interaction effects (group by time) to estimate mean differences in FAQ and TFEQ scores using intent-to-treat analysis. After adjusting for employment, education, food security status, sex, and age, there were no differences in any of the FAQ items, total FAQ score, dietary restraint, disinhibition, and hunger at any timepoint except for one item of the FAQ at 12 months. Participants in the vegan group reported a greater increase in satisfaction after eating a meal than the omnivorous group (mean difference 0.80 ± 0.32, 95% CI 0.18, 1.42; P = 0.01). This is one of the first studies to examine differences in dietary acceptability, hunger, and other eating factors among African American adults randomized to either a vegan or omnivorous soul food diet. The findings highlight that plant-based eating styles are equally acceptable to omnivorous eating patterns and have similar changes in hunger, restraint, and disinhibition. These results suggest that plant-based eating styles can be an acceptable dietary pattern to recommend for cardiovascular disease prevention and may result in greater post-meal satisfaction.

Abstract
CONTEXT Shifting from current dietary patterns to diets rich in plant-based (PB) foods and lower in animal-based foods (ABFs) is generally regarded as a suitable strategy to improve nutritional health and reduce environmental impacts. Despite the recent growth in supply of and demand for novel plant-based foods (NPBFs), a comprehensive overview is lacking. OBJECTIVES This review provides a synthesis of available evidence, highlights challenges, and informs public health and environmental strategies for purposeful political decision-making by systematically searching, analyzing, and summarizing the available literature. DATA SOURCES Five peer-reviewed databases and grey literature sources were rigorously searched for publications. DATA EXTRACTION Study characteristics meeting the inclusion criteria regarding NPBF nutrient composition and health and environmental outcomes in high-income countries were extracted. DATA ANALYSIS Fifty-seven peer-reviewed and 36 grey literature sources were identified; these were published in 2016-2022. NPBFs typically have substantially lower environmental impacts than ABFs, but the nutritional contents are complex and vary considerably across brands, product type, and main primary ingredient. In the limited evidence on the health impacts, shifts from ABFs to PB meats were associated with positive health outcomes. However, results were mixed for PB drinks, with links to micronutrient deficiencies. CONCLUSION If carefully selected, certain NPBFs have the potential to be healthier and nutrient-rich alternatives to ABFs and typically have smaller environmental footprints. More disaggregated categorization of various types of NPBFs would be a helpful step in guiding consumers and key stakeholders to make informed decisions. To enable informed policymaking on the inclusion of NPBFs in dietary transitions as part of a wider net-zero and health strategy, future priorities should include nutritional food standards, labelling, and subdivisions or categorizations of NPBFs, as well as short- and long-term health studies evaluating dietary shifts from ABFs to NPBFs and standardized environmental impact assessments, ideally from independent funders.

Abstract
Introduction Although vegan and vegetarian diets and lifestyles differ significantly from each other, among other things, notably in their respective consequences regarding animal welfare and their ecological impact, vegans and vegetarians are often grouped together and usually compared to omnivores in psychological research. Considering that vegans and vegetarians often share similar motives for their lifestyle choices, namely animal and environmental issues, the question arises why similar motives lead to different conclusions and correspondingly different behaviors, most notably, of course, that vegetarians consume animal-derived foods such as cheese or milk while vegans do not consume animal-derived products (e.g., food, cosmetic products). This is why this study explored the psychological differences between vegans, vegetarians, and prospective vegans - the latter group being located in an intermediate, transitionary position. Focusing on the motivational, affective and cognitive components of dietary transition and participants' adherence to eating patterns, reasons for said patterns, possible hinderances to becoming vegan, the role of participants' social environments, and the impact of various misconceptions regarding the feasibility of a vegan diet in everyday life were all explored. Methods An observational study was conducted via online questionnaire (1420 participants). Results Significant differences were found between vegans, prospective vegans, and vegetarians, especially concerning their knowledge of issues pertaining to their respective lifestyles. Discussion The critical role of knowledge is invoked as an explanation as to why vegans and vegetarians display different behaviors although they share a similar motivation. Thus, in this study the concept of vegan literacy is introduced. Additionally, the distinctive role of cheese is explored, discussing possible indications of its potentially addictive nature and, consequently, the importance of cheese as a hindering factor for pursuing a vegan diet.

Abstract
Adopting a plant-based diet (PBD) has been shown to reduce the risk of developing certain diseases and is linked to environmental benefits. This review synthesises the evidence on the barriers adults aged 18 to 65 living in high-income countries (HIC) may experience when adopting a PBD. A systematic literature review was conducted using four search databases: Medline, Embase, Global Health, and Web of Science. Barriers were mapped to behaviour change strategies using the COM-B model. Ten studies were included in the final review, including 1740 participants. Five were qualitative, four were cross-sectional, and one was a pre- and-post-intervention study. In total, 40 barriers were identified and synthesised into 11 themes: financial, lack of knowledge, emotional, health, convenience, social, enjoyment of meat, environmental, accessibility, personal ability, and media. Of the 40 barriers, nutritional intake/requirements (categorised into the "health" theme) had the most evidence. This barrier encompassed concerns around being able to meet nutritional needs if an individual were to adopt a PBD. Habits (in the "personal ability" theme), which included established eating habits and habitual behaviours relating to animal-source foods, had the second most evidence alongside the barrier of not knowing what to eat as part of a PBD (in the "lack of knowledge" theme). Education interventions and communication/marketing policies were the behaviour change mechanisms mapped onto these barriers. Future interventions should focus on informing individuals about what to consume as part of a nutritionally balanced PBD and facilitating habitual dietary change.

Abstract
Whole foods plant-based diets (WFPBD) show potential for preventing and addressing chronic diseases. However, concerns exist about their acceptability and feasibility. Research on firsthand WFPBD adoption experiences is limited but crucial for promoting dietary change. In a 12-week remotely delivered lifestyle modification program using an ad libitum WFPBD, twenty weight-loss seeking adults (ages 18-75) with overweight or obesity completed self-report surveys and semi-structured interviews via Zoom. The study aimed to explore: (1) experiences with WFPBD adoption; (2) factors that helped or hindered adherence; and (3) perceived salient benefits. Interviews were analyzed inductively through a conventional content analysis, and associations between variables examined with correlational analyses. Participants overall reported WFPBD adoption being a positive, new experience, with an equal number (30%) finding it easy/easier than expected as challenging. Key cited challenges included overwhelm, different eating habits in the household, and meal preparation. Key cited facilitators included adopting an incremental approach to dietary change, persisting after setbacks, and having simple go-to meals. Greater self-compassion and family support, and less sabotage from friends and family corresponded to greater dietary change (rs > 0.45, ps < .05). Participants valued accountability, structure, human support, nutrition psychoeducation and recipes in the program. Three categories emerged regarding perceived benefits of following the WFPBD: physical health benefits, improvements to eating habits, and greater perceived control/agency over health. Results indicate that future interventions should include psychological strategies alongside nutrition education to enhance self-efficacy, address household barriers, and combat feelings of overwhelm through sufficient structure, support, and meal preparation guidance. Messaging around WFPBD may benefit from discussing prevailing positive experiences with adoption, common benefits experienced, and options for an incremental approach given that feasibility and acceptability concerns may deter efforts.

Abstract
Many diagnosed with cancer change their diet in response to the diagnosis, with a vegan diet being a common choice. There may be health benefits to this, but research has demonstrated that following a vegan diet can have negative social ramifications. These social ramifications seem to be experienced to a lesser extent by those who following a vegan diet for health versus moral reasons, but this is a heterogeneous group; people may choose the diet for a myriad of different health reasons. In two pre-reregistered studies, we examined the social experience of those who adopt a vegan diet following a cancer diagnosis. Study 1, an experimental study, demonstrated that omnivores responded more positively to a friend who was vegan for cancer reasons than animal or general health reasons, which was explained by increased empathy. In Study 2, a cross-sectional survey study, those who adopted a vegan diet due to cancer reported (overall) less negative social experiences than those following a vegan diet more generally. These participants reported that cancer represented a greater social challenge than their diet. Taken together, these findings suggest that "vegan due to cancer" is a unique social identity and a unique social experience, relative to that of those motivated by other reasons, including general health reasons.

Abstract
Introduction Gender differences have been identified in both the engagement in and the determinants of sustainable diet behaviours. However, as engagement in pro-environmental behaviours varies across countries, the consistency of gender differences could follow similar patterns. Understanding the factors underlying gender and country differences in diet intentions is important for determining how to promote sustainable diets in different populations. Methods Using survey data from the UK, China, Sweden and Brazil (N=4,569), this paper examines the influence of subjective norms, diet-related identity, perceived status of meat consumption, environmental identity and environmental concern on sustainable diet intentions. Multigroup analysis was used to explore gender and country differences in the influence of these variables, and whether gender differences were consistent across the four countries. Results The findings show that there are gender differences in the influence of diet-related identity and perceived status of meat consumption, as well as cross-country differences in all factors except subjective norms. Holding a strong diet-related meat identity negatively affected sustainable diet intentions in all groups. Crucially, however, gender differences are not consistent across countries. Discussion These results suggest that individuals' intentions to engage in sustainable diet behaviours are influenced by nationally unique gender associations.

Jirovsky-Platter E, Wakolbinger M, Kühn T, Hoffmann K, Rieder A, Haider S. Experiences of Vegans with General Practitioners in the Austrian Health Care System: A Qualitative Study. Nutrients 2024; 16:392. [PMID: 38337677 PMCID: PMC10856837 DOI: 10.3390/nu16030392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 01/24/2024] [Accepted: 01/24/2024] [Indexed: 02/12/2024] Open
Abstract
This article explores the factors influencing the choice of general practitioners (GPs) and their role in the health care of vegans in Austria. The number of people identifying as vegan is on the rise, and GPs are increasingly confronted with vegan patients. A qualitative method was chosen for this study, and 14 semi-structured interviews with vegans were conducted between April 2022 and July 2022. Participants were recruited primarily through vegan social media groups. In their experiences with health care, vegans felt treated unequally or sometimes incorrectly. The experiences described highlight that participants felt that most GPs were biased against their veganism. Information exchange among vegans primarily takes place online and through publications of vegan associations, while GPs play a minor role in information provision. As the number of vegans grows, an appreciative way of communicating between GPs and vegan patients ought to be promoted. Voluntary interdisciplinary nutritional training, collaboration of the medical field with support organizations, provision of evidence-based information, and collaboration with dietitians and nutritionists could enrich the care of patients with a vegan diet.

Abstract
The objective of this scoping review was to examine the breadth of the existing literature on the relation between meat consumption or meat abstention and positive psychological functioning. In April 2022, we conducted a systematic search of online databases (PubMed, PsycINFO, CINAHL Plus, Medline, Cochrane Library, and Web of Science) for primary research examining positive psychological functioning in meat consumers and those who abstain from meat. Thirteen studies met the inclusion/exclusion criteria, representing 89,138 participants (54,413 females and 33,863 males) with 78,562 meat consumers and 10,148 meat abstainers (13-102 years) from multiple geographic regions. The primary outcomes were life satisfaction, "positive mental health", self-esteem, and vigor. The secondary outcomes were "meaning in life", optimism, positive emotions, and psychological well-being. Eight of the 13 studies demonstrated no differences between the groups on positive psychological functioning, three studies showed mixed results, and two studies showed that compared to meat abstainers, meat consumers had greater self-esteem, "positive mental health", and "meaning in life". Studies varied substantially in methods and outcomes. Although a small minority of studies showed that meat consumers had more positive psychological functioning, no studies suggested that meat abstainers did. There was mixed evidence for temporal relations, but study designs precluded causal inferences. Our review demonstrates the need for future research given the equivocal nature of the extant literature on the relation between meat consumption and meat abstention and positive psychological functioning.

Abstract
INTRODUCTION The current food system is associated with negative impacts on health, food insecurity and environmental harm. Sustainable diets have attracted increasing interest and novel proposals with a global scope have emerged. This scoping review aims to give an overview of the analysis of all the available evidence related to the sustainable diet indices that have been developed based on the EAT-Lancet Commission. METHODS Searches were conducted in the PubMed, Embase, Web of Science, Scopus and Science Direct databases. This review was conducted following the PRISMA-ScR guidelines. The target population were studies addressed the use of an index or metric for assessing sustainable diets based on the EAT-Lancet Commission Summary Report were included. PCC acronym was used in the design of the study to describe eligibility criteria: P (Population)-Indexes; C (Concept)-Sustainable diets; C (Context)-Knowledge on the structure and applicability of measurement indices of sustainable diets based on EAT-Lancet recommendations available in the literature. Study eligibility criteria were restricted to papers published in English, from January 2019 through October 2022, with no population restriction. RESULTS A total of 1,458 papers were retrieved, 14 of which were included in the review. Seven measures of sustainable diets were identified as follow: EAT-Lancet diet score (ELD-I), New EAT-Lancet diet score (EAT), Planetary Health Diet Index (PHDI), Sustainable Diet Index (SDI), Sustainable-HEalthy-Diet (SHED), novel Nutrient-Based EAT index (NB-EAT) and World Index for Sustainability and Health (WISH). Most studies were conducted in developed countries, where greater adherence to this type of diet was found. Estimated greenhouse gas emissions was the most reported indicator of sustainability, followed by diet quality and the benefits of sustainable diets with regards to health outcomes. DISCUSSION We identified barriers that hinder progress towards sustainable diets, including the difficulty of comparing different indices and the tendency to neglect social aspects and the lack of common definitions and metrics. Despite being challenge, we highlight the importance of using indices that assess sustainable diets that harmonize various indicators, as recommended by the EAT-Lancet Commission, in order to promote positive changes towards a more sustainable future.

Abstract
Participants, 672 US collegians, listed four words/terms that first came to mind when thinking of vegans, non-vegan vegetarians, and omnivores. Participants generated 1264 unique descriptors, which two sets of raters, who were blind to the source of the descriptors, rated on 10 dimensions that included the valence of the descriptors (i.e., positive, negative). A series of multilevel models in which descriptors were nested within persons, found that descriptors referring to environmental issues and health were used more frequently when describing both vegans and vegetarians than when describing omnivores. Descriptors referring to deviance, lifestyle, and politics were used more frequently when describing both vegans and vegetarians than when describing omnivores. Overall, vegans were viewed more negatively than vegetarians who were viewed more negatively than omnivores. These differences were moderated by the extent to which participants restricted meat from their diet. Those who restricted meat from their diets to a greater extent had more negative perceptions and fewer positive perceptions of omnivores, whereas they had more positive perceptions of vegans and vegetarians, and fewer positive perceptions of omnivores. The present study is the first to use spontaneous verbal reports to examine attitudes and perceptions of people based on their eating habits. The results suggest that dietary habits can serve as a basis for social identity, which in turn affects perceptions of others.

Abstract
Vegan diet has emerged as a popular dietary choice for people worldwide in recent times, due to concerns such as health issues, animal rights and welfare, and the sustainability of the environment. The purpose of this literature review was to explain how a vegan diet may affect the health of adults and to point out beneficial components found in it as well as any difficulties associated with its implementation. Evidence supports that a vegan diet can reduce the risk of chronic diseases, such as type 2 diabetes, hypertension, and certain types of cancer. A well-planned vegan diet must include adequate calories and nutrients, as well as the necessary supplements, such as vitamin B12, vitamin D and EPA/DHA. Given the current growing interest in plant-based diets among the general population, it is crucial to understand both the barriers, risks, and benefits of the vegan diet among physicians, policy makers, and the general population.

"I guess it's quite trendy": A qualitative insight into young meat-eaters' sustainable food consumption habits and perceptions towards current and future protein alternatives.

[PMID: 37696470 DOI: 10.1016/j.appet.2023.107025] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 09/01/2023] [Accepted: 09/02/2023] [Indexed: 09/13/2023]
Abstract
As the market for sustainable food continues to expand, there is a need to understand how consumers' consumption habits and perceptions are changing. Targeting the younger populations is of interest as they arguably will shape the future of food. Therefore, the present study aimed to provide in-depth consumer insights on a range of topics from current consumption habits (i.e., meat reduction, plant-based meat/seafood (PBM/S)), towards future protein alternatives (i.e., cell-based meat/seafood (CBM/S), precision fermented dairy (PFD)). Online focus groups were conducted in the UK with meat-eaters (n = 38) aged 18-34. Codebook thematic analysis was applied using the Framework Matrix as a tool for data analysis. Key themes were presented using the COM-B model (Capability, Opportunity, Motivation), which identified areas of behavioural change. Results found a trend towards meat reduction, partially initiated by moving away from home and limited food budgets. Overall, participants acknowledged the environmental impact of food, but a notable knowledge gap was apparent when quantifying the effect, especially for dairy and seafood. Compared to PBM, few participants had tried PBS products, partially due to lower availability and familiarity. Enablers for PBM/S included convenience, positive sensory experiences and the influence of others, whilst barriers related to negative health connotations and over-processing. For CBM/S and PFD, animal welfare, curiosity and optimised nutrition acted as enablers, whilst barriers related to wider consumer acceptance, affordability and unnaturalness. In general, participants felt changing food consumption habits can have an impact on climate change and were optimistic about novel technologies supporting future protein transitions. Increasing public understanding around the environmental impact of food, especially seafood and dairy, and prioritising the affordability of sustainable food are suggested as intervention strategies to encourage sustainable food consumption.

Abstract
In two pre-registered experiments, we assessed how people cognitively represent meat and plant-based foods, to examine processes underlying dietary polarization in society. Food descriptions from U.K.-based omnivores (NExp. 1 = 109; NExp. 2 = 436) and vegans (NExp. 1 = 111; NExp. 2 = 407) were coded for features about consumption and reward (e.g., "rich," "indulgent," and "treat") or features independent of the consumption situation (e.g., "healthy," "protein," and "eco-friendly"). Participants used more consumption and reward features for diet-congruent dishes (meat dishes for omnivores and plant-based dishes for vegans) than for diet-incongruent dishes (vice versa). Omnivores focused on abstract, long-term consequences of plant-based foods, whereas vegans focused on the socio-political associations with meat foods. Consumption and reward features also positively predicted attractiveness ratings, the likelihood of ordering a dish, and eating intentions. These findings indicate the cognitive processes of polarized dietary groups that may hinder the mainstream transition to more sustainable food choices.

Abstract
There has been an increased emphasis on plant-based foods and diets. Although mobile technology has the potential to be a convenient and innovative tool to help consumers adhere to dietary guidelines, little is known about the content and quality of free, popular mobile health (mHealth) plant-based diet apps. The objective of the study was to assess the content and quality of free, popular mHealth apps supporting plant-based diets for Canadians. Free mHealth apps with high user ratings, a high number of user ratings, available on both Apple App and GooglePlay stores, and primarily marketed to help users follow plant-based diet were included. Using pre-defined search terms, Apple App and GooglePlay App stores were searched on December 22, 2020; the top 100 returns for each search term were screened for eligibility. Included apps were downloaded and assessed for quality by three dietitians/nutrition research assistants using the Mobile App Rating Scale (MARS) and the App Quality Evaluation (AQEL) scale. Of the 998 apps screened, 16 apps (mean user ratings±SEM: 4.6±0.1) met the eligibility criteria, comprising 10 recipe managers and meal planners, 2 food scanners, 2 community builders, 1 restaurant identifier, and 1 sustainability assessor. All included apps targeted the general population and focused on changing behaviors using education (15 apps), skills training (9 apps), and/or goal setting (4 apps). Although MARS (scale: 1-5) revealed overall adequate app quality scores (3.8±0.1), domain-specific assessments revealed high functionality (4.0±0.1) and aesthetic (4.0±0.2), but low credibility scores (2.4±0.1). The AQEL (scale: 0-10) revealed overall low score in support of knowledge acquisition (4.5±0.4) and adequate scores in other nutrition-focused domains (6.1-7.6). Despite a variety of free plant-based apps available with different focuses to help Canadians follow plant-based diets, our findings suggest a need for increased credibility and additional resources to complement the low support of knowledge acquisition among currently available plant-based apps. This research received no specific grant from any funding agency.

Abstract
OBJECTIVES The growing popularity of diets that restrict the consumption of animal-based foods is an important new challenge for the public healthcare system in Czechia. While the environmental and health-related benefits of plant-based diets are widely discussed in the media, people who follow these diets may lack professional support in terms of nutritional advice and even access to healthcare. The present study aims to map the nutritional practices and experiences with the healthcare system of people in Czechia who follow vegan diets. METHODS In a qualitative study we conducted semi-structured interviews with twenty-one self-reported adult vegans (14 women and 7 men; 18 with university education) who were on a vegan diet for at least a year. We were specifically interested in their motivation for why and how they became vegans; their everyday diet and eating routines; their use of health care and experiences with medical professionals; their nutritional knowledge and use of supplementation; and their perception of their health and embodiment. RESULTS The primary motivations for going vegan are ethical, environmental and health-related. Vegans see themselves and their diet as generally healthier, but for this to be true they must spend a considerable amount of time researching nutritional requirements and what dietary supplements they need. To this end, they tend to rely mainly on non-medical sources of information. Because of the lack of acceptance of veganism among primary-care physicians, vegans tend not to seek out medical advice or tell their doctor about their eating habits in order to avoid conflicts and negative experiences. CONCLUSIONS We identified a perceived lack of accessible educational materials and potentially limited access to primary healthcare recommendations for people who eliminate the consumption of animal-based foods. These findings deserve further research and public health risk-mitigation strategies.

Abstract
Plant-forward diets offer a potential solution to many of the health and ecological crises that we find ourselves facing today. A key barrier to the adoption and maintenance of plant-forward diets is an anticipated lack of support from family members, friends and romantic partners. The present study examined how relational climate (i.e., the cohesion and flexibility of a partnership) contributes to the tension individuals anticipate in their relationship when a member reduces their animal-product consumption, and their own openness to reducing. Four hundred and ninety-six coupled individuals took part in an online survey. Analyses revealed that couples with more flexible leadership styles anticipated less tension should they or their partner adopt a plant-forward diet. However, dimensions of relational climate were largely unrelated to openness to plant-forward diets. Romantic couples who perceived themselves to be matched in terms of dietary habits were less open to reducing their animal-product consumption than unmatched couples. Politically left-leaning couples and females were more open to plant-forward diets. The meat attachments of male partners were reported as a particular barrier to dietary goals, as were practical concerns about meal coordination, finance, and health. Implications for promoting plant-forward dietary transitions are discussed.

Abstract
Researchers interested in animal ethics have proposed the 'meat paradox' - psychological discomfort arising from people's affinity for animals and conflicting desire to consume their flesh. Yet what can be said about the psychology of consuming an animal's non-meat products, in an age where most beings in these industries are harmed, and ultimately killed? Non-meat animal products (NMAPs) such as eggs and dairy entail the same, and perhaps even worse ethical issues as meat yet receive disproportionately less critical attention. Therefore, unlike meat, very little is known about the psychology of egg and dairy consumption. This study looks at vegetarians to address this gap, because they are more likely to show empathetic concern for animals than meat-eaters, yet actively choose to include these products in their diet, a conflict ripe for exploration. Interview data were analysed via thematic analysis, finding that vegetarians perceive robust ethical issues with NMAPs but give various justifications pertaining to personal benefits and social norms. Cognitive dissonance was evident and participants used various strategies to resolve it. This paper expands research on food psychology and animal ethics and may also be used to inform NMAP reduction strategies, an important pursuit in the quest for a more sustainable and compassionate world.

Abstract
Meat reduction is gaining attention among consumers, marketers, policymakers and scientists. Yet little is known about decision-making processes and behaviour change towards meat reduction. This paper explores the applicability of the decisional balance (DB) framework to the field of meat reduction. A novel DB scale to measure the perceived importance of beliefs about meat reduction at different stages of behaviour change was developed and validated in two studies with German meat eaters. In Study 1 (N = 309), the item inventory was tested using an exploratory factor analysis and then validated in Study 2 (N = 809). The results yielded two higher-order DB factors (pros and cons), which were subdivided into five lower-order factors (perceived benefits of a plant-based diet, downsides of factory farming, health barriers, legitimation barriers and feasibility barriers). The pros and cons were summarised in a DB index. All DB factors and the DB index were tested for internal consistency (Cronbach's alpha ≥.70) and aspects of validity. The typical DB pattern of the pros and cons of behaviour change was confirmed: the cons outweighed the pros for consumers who did not intend to reduce meat consumption, while the pros outweighed the cons for consumers who intended to reduce meat consumption. The new DB scale for meat reduction has proven to be a suitable measure to gain insights into consumers' decision making and could be used to develop targeted meat reduction interventions.

Abstract
A reduction of meat consumption is crucial for addressing public health problems, especially in industrialized countries. Among low-cost interventions, emotionally provocative health-information strategies could be effective options in fostering meat reduction. Through an online experimental survey, administrated to a quota-based national sample (N = 1142), this study analysed the profile of Italians consuming red/processed meat above World Health Organization (WHO) recommended amounts. Via a between-subjects design, the research tested whether two health frame-nudges (societal impact and individual impact of over consumption) persuaded these individuals to reduce future meat consumption. Results showed that adhering to an omnivore diet, higher consumption of meat than peers, household size (larger) and positive moral perception of meat consumption increased the likelihood of overconsumption. In addition, both nudges proved to be effective in positively impacting future intentions to reduce meat consumption among individuals exceeding WHO recommended amounts. The two frame-nudges were more effective among females, respondents with children in the household and individuals with a low health status perception.

Abstract
Reducing one's consumption of foods containing animal products, or avoiding such foods altogether, has become part of everyday life for many people in the Western world. People's motivations for such "animal product limiting" are well-established, but the ways in which individuals enact and experience dietary change in the initial phase are not well understood. Nor is it clear whether, and how, these people present their dietary changes to others. Through the analysis of interviews with 28 people residing in Denmark who had recently (<9 months) embarked on flexitarian, vegetarian or vegan diets, this paper explores how people, in the initial phase of trying to consume fewer, or no, foods with animal products, (i) engage in the practicalities of daily food activities and (ii) communicate their experiences with, and opinions about, the dietary changes they are making in interpersonal interactions. The findings reveal two very different ways of organising the daily food activities: Foodism and Convenience. They also disclose three different ways of communicating in interpersonal interactions: Ethical advocacy, Plant food demonstration and Anonymisation of diet. The paper offers insights into the variation in practices underlying animal product limiting. It suggests that the plant food sector should cater for people relying on convenient food practices as well as those engaged in more advanced ("foodie") practices. Further, in discussing interpersonal communication in the light of community-based social marketing, we argue that the findings highlight how animal product limiters, in everyday social life, may be able to encourage more people to embark on animal product limiting.

Abstract
A body of research has shown that violent protests reduce support for social movements. However, few studies have examined whether the same is true for protests which are peaceful, yet disruptive (e.g., blocking traffic). Across two pre-registered experimental studies, we explored whether pro-vegan protests that are depicted as causing social disruption lead to more negative attitudes towards veganism, compared to non-disruptive protests or a control condition. Study 1 utilised a combined sample of Australian and United Kingdom residents (N = 449; Mage = 24.7 years). Study 2 employed a larger sample of undergraduate Australian students (N = 934; Mage = 19.8 years). In Study 1, disruptive protests were associated with more negative attitudes towards vegans, but only among women. In Study 2, no such effect was found. Instead, a significant main effect was found for the protest's cause (vegan vs. fast fashion), but not protest type (disruptive vs. non-disruptive). That is, reading about a vegan protest, irrespective of how disruptive it was, led to worse attitudes towards vegans, and greater defense of meat consumption (i.e., endorsement of meat eating as natural, necessary, and normal), than reading about a control protest. This effect was mediated by the perceived immorality of the protestors, and, in turn, reduced identification with them. Taking together both studies, the purported location of the protest (i.e., domestic vs. overseas) did not significantly impact attitudes toward the protestors. The current findings suggest that depictions of vegan protests elicit worse attitudes toward this movement, regardless of how peaceful that protest may be. Future research is needed to examine whether other forms of advocacy can ameliorate negative reactions to vegan activism.

Abstract
Exploring everyday life dynamics in meat reduction - a cluster analysis of flexitarians in Denmark. Flexitarians are attracting increasing attention in the research on meat reduction. But there has been limited focus on comprehensive understandings of a broader range of dynamics that can work as barriers and facilitators for meat reduction. In this article, we use social practice theory (SPT) as a comprehensive approach to barriers and facilitators in meat reduction in everyday life. We present an analysis of data from a representative Danish cross-sectional survey. We show, first, that Danish flexitarians can be divided into four distinct clusters (what we will refer to as classes) in accordance with combinations of everyday facilitators and barriers. Second, we show that the prevalence of these classes varies considerably depending on how long people have been flexitarians. We argue that the patterns in this variation indicate that over time people transition to other classes where barriers to plant-rich eating become less significant, and routinization emerges in different ways. Finally, third, we show that flexitarians do report eating less meat than consumers who label themselves as eating meat with no restrictions. But we also highlight that the difference is relatively modest. Indeed, meat intake is still quite common even in classes where routinization is highest. Throughout the paper, we discuss similarities and differences between the SPT framework and another recent framework, the COM-B model, that also provides a comprehensive approach to the understanding of behavioural change.

Abstract
A vegan diet, which excludes all animal-derived products, has been associated with some improvements in health, while also conferring environmental benefits. Understanding the psychological determinants of successfully switching to a vegan diet will help to inform the design of interventions supporting long-term dietary change. Studies to date have tended to focus on reasoned motives underlying the decision to initiate such a dietary shift. Yet, focusing on reasons for switching may overlook the importance of a broader range of psychological factors that may help or hinder attempts to maintain a vegan diet. This qualitative interview study, the timing of which coincided with UK Covid-19 lockdowns, documented experiences of 20 young adults (17 female; mean age 22y) who attempted to adopt a vegan diet in the past nine months and had or had not successfully maintained this change. Reflexive Thematic Analysis identified five themes surrounding initiation and maintenance. A theme of 'motives, expectations and cues to switching' showed that switching was motivated by ethical or health concerns, and cued by Veganuary, lockdown or health issues. 'The effortfulness of switching' captured experiences of the perceived burden imposed by adhering to the diet due to, for example, a perceived lack of accessible vegan options. The 'flexibility of dietary rules' theme showed that many found the 'no animal products' rule clear but restrictive, so allowed themselves occasional non-meat animal products. 'Social acceptability concerns' captured the importance of acceptance from vegan and non-vegan family and friends, and 'satisfaction with the switch' described the perceived benefits that sustained maintenance for many. Our findings suggest that interventions should seek to support people to overcome potentially unforeseen practical and social challenges to adhering to a vegan diet.

Abstract
Socioeconomic status has been related to poorer eating behaviors, potentially due to feeling of lower status relative to peers. Despite experimental evidence that temporarily feeling of lower status can contribute to greater caloric intake, it remains unclear how feeling of lower social status relate to eating behavior in daily life. This study aimed to test whether lower subjective social status (SSS)-the feeling of having relatively lower social status-in American society and relative to college peers were related to daily food selection. A sample of 131 young adults (Mage = 20.3, SD = 0.8; 60% female; 46% Latinos; 34% European American; 15% Asian American; 5% of other ethnicities) reported their SSS in society and in college and completed 15 daily reports regarding the number of daily servings they had of fruits, vegetables, fried foods, fast foods, desserts, and sugary drinks. Multilevel models with days nested within individuals were used to test whether low SSS in society or college related to daily food intake. Next, we examined whether associations were driven by young adults' perceived stress and daily stressors. Analyses controlled for age, gender, ethnicity, family and personal income, and parents' education to test the unique associations between subjective status and food intake. Whereas SSS in society was not related to food intake, young adults with lower SSS in their college consumed fewer daily servings of healthy foods and more daily servings of high-fat/high-sugar foods. Although lower college SSS was related to greater perceived stress, perceived stress and daily stressors were consistently unrelated to daily food intake. Findings suggested that lower SSS in local environments (e.g., college) may impact young adults' daily food choices through processes beyond heightened stress.

Abstract
BACKGROUND Nutrition information-seeking behavior is highly prevalent even though it can be challenging to find reliable nutrition information in the current media landscape. Previous quantitative research has identified which population segments use which sources, yet little is known about motivations underpinning nutrition information-seeking behavior. Understanding motivations for seeking nutrition information can increase the efficacy of future nutrition education efforts. The present study aims to identify motivations for nutrition information-seeking behavior among Belgian adults. METHODS In-depth qualitative interviews were conducted with 20 adults (n women = 15, n men = 4, n other = 1). Audio-recorded interviews were transcribed verbatim and analyzed in NVivo 12 using inductive thematic analysis. The coding process involved open and axial coding combined with constant comparison to identify themes. RESULTS The interviews revealed a diverse spectrum of motivations for nutrition information-seeking behavior. Five categories of motivations centered on health management, cognitive needs, affective needs, social integrative needs, and personal identity. Participants indicated seeking nutrition information to regain a sense of control over their health and it also helped them express their autonomy. Additionally, participants sought nutrition information out of curiosity or out of a long-standing interest. Nutrition information-seeking was also used as a form of emotion regulation with participants actively engaging in seeking behavior to pursue enjoyment, diversion, confirmation, inspiration, and even relaxation. Furthermore, nutrition information-seeking enabled participants to meet social integrative needs by helping them connect to others, gather social support, help others, and sometimes convince others. Lastly, participants indicated a need for nutrition information to express or defend their identity. CONCLUSIONS Our results indicate that beneath the surface of a more apparent need for nutrition information lies a range of motivations demonstrating that nutrition information serves more complex needs than simply information needs. To improve the efficacy of future nutrition education efforts, communication strategies must be tailored to a diverse range of motivations.

Abstract
In studies conducted in the US and Poland, vegans, non-vegan vegetarians, pescatarians, and omnivores described how they perceived they were treated by others as a function of their diet. We found that vegans thought that others treated them more negatively because of their diets than vegetarians or pescatarians did, and pescatarians thought that others treated them less negatively than vegans and vegetarians did. In Study 1 (N = 96), we found that vegans, vegetarians, and pescatarians thought that others treated them more negatively because of their diet than omnivores did. Moreover, perceptions of negative treatment were positively related to how much participants' diets differed from an omnivorous diet. We replicated these findings in Study 2 (N = 1744), and we also found that vegans, vegetarians, and pescatarians thought that others treated them more positively in some ways compared to omnivores. In Study 3 (N = 1322), we found that differences in perceptions of negative treatment by strangers among vegans, vegetarians, and pescatarians were larger than differences in perceptions of treatment by friends and family members.

Abstract
Previous studies have consistently shown that autonomous motivation - pursuing goals because one wants to, rather than has to - is associated with greater behaviour maintenance in the context of healthy eating, exercise, and diet maintenance. The present study used a 7-wave longitudinal design to examine how autonomous motivation is related to dietary goal progress in individuals (N = 222) transitioning to a veg*n (i.e., vegetarian or vegan) diet. We hypothesized that when people reported more autonomous motivation (compared to their own average) they would be more successful in reaching their dietary goals. We also explored the role of goal-facilitating behaviours in this process. We found no directional effects of relative autonomous motivation on goal progress or goal-facilitating behaviours, although the concurrent relations were significant. There were also no within-person effects of behaviours on progress. These findings shed light onto the relationship between autonomous motivation, behaviours, and goal progress both at the same time and over time, and highlight the importance of examining within-person fluctuations over time.

Abstract
Planetary and human health depend on Westerners' ability to reduce meat consumption. Meat production degrades the environment while excessive meat intake is associated with cancer and cardiovascular disease, among others. Effective reasons and motivations are needed for consumers to change their diet. The fact that modern animal agriculture inflicts a great deal of pain on animals from their birth to their slaughter, animal welfare/suffering may drive consumers to curtail their meat consumption. This systematic review examined a total of 90 papers to ascertain consumers' awareness of the pain animals experience in animal agriculture, as well as consumer attitudes towards meat reduction due to animal welfare. Results show that consumers have low awareness of animal agriculture. Awareness of animal agricultural practices and animal sentience is associated with increased negative attitudes towards animal suffering. Animal suffering due to farming practices, transportation, slaughter, and animal sentience are factors that may encourage a reduction in meat consumption, and even dietary change in the short term. There is also evidence that animal suffering may be a more compelling motivation for consumers' willingness to change their diet than for health or environmental reasons. Therefore, increasing consumers' awareness of animal suffering in meat production is paramount to contributing to reduced pressure on the environment and improved human health.

Abstract
Animal-based diets in Western countries are increasingly regarded as unsustainable because of their impact on human health, environmental and animal welfare. Promoting shifts toward more plant-based diets seems an effective way to avoid these harms in practice. Nevertheless, claims against the consumption of animal products contradict the ideology of the omnivorous majority known as carnism. Carnism supports animal-product consumption as a cherished social habit that is harmless and unavoidable and invalidates minorities with plant-based diets: vegetarians and vegans (veg*ns). In this theoretical review, we integrate socio-psychological and empirical literature to provide an identity-based motivational account of ideological resistance to veg*n advocacy. Advocates who argue against the consumption of animal products often make claims that it is harmful, and avoidable by making dietary changes toward veg*n diets. In response, omnivores are likely to experience a simultaneous threat to their moral identity and their identity as consumer of animal products, which may arouse motivations to rationalize animal-product consumption and to obscure harms. If omnivores engage in such motivated reasoning and motivated ignorance, this may also inform negative stereotyping and stigmatization of veg*n advocates. These "pro-carnist" and "counter-veg*n" defenses can be linked with various personal and social motivations to eat animal products (e.g., meat attachment, gender, speciesism) and reinforce commitment to and ambivalence about eating animal products. This does not mean, however, that veg*n advocates cannot exert any influence. An apparent resistance may mask indirect and private acceptance of advocates' claims, priming commitment to change behavior toward veg*n diets often at a later point in time. Based on our theoretical account, we provide directions for future research.

Abstract
Several scientists have shown the importance of mitigating global warming and have highlighted a need for major social change, particularly when it comes to meat consumption and collective engagement. In the present study (N = 486), we conducted a cross-sectional study to test the mismatch model, which aims at explaining what motivates individuals to participate in normative change. This model stipulates that perceiving a self—other difference in pro-environmental attitudes is the starting point and can motivate people to have high pro-environmental intentions. This mismatch effect is explained by participants’ willingness to participate in normative and social change: people that perceive a gap between their personal attitude and the social norm should be more willing to participate in normative change. This should then motivate them to have high pro-environmental intentions on an individual and group level. The results confirm the hypothesized model on an individual and group level and explain how people can be motivated to participate in normative change. Implications of these findings and the need for further studies are discussed.

Abstract
An interesting finding in the literature on vegetarianism and veganism finds that vegetarians and vegans often report that they deviate from their diets from time to time. Work examining this phenomenon finds that these dietary lapses relate to many factors; however, little research examines how these factors collectively influence dietary lapses while also controlling for the relationships that may exist among factors. Here, I fill this gap by drawing from the unified model of vegetarian identity (UMVI) and identity theory (IT) to propose an inclusive model of dietary lapses. Structural equation model results from a sample of 488 vegans reveal differences in how identity and interactional processes relate to dietary lapses across ethical and health motivations. This work is important because it highlights how identities relate to dietary behaviors differently for ethical and health vegans; it also provides fruitful avenues for future work in this area.

Abstract
Given the increasing popularity of vegan labels, our study examines the effect of vegan labeling on product perceptions and consumption intentions. We focus on randomly-vegan products which are products that have neither undergone any special reformulation to be vegan nor explicitly aim to serve the market segment of vegans and vegetarians. Food marketers are often tempted to add a vegan label to their randomly-vegan products to capitalize on the growing popularity of vegan food. Our results show that labeling randomly-vegan products biases the perceived healthiness, expected taste, and perceived sustainability, but only if consumers do not expect such randomly-vegan products to be vegan by default. This translates into altered consumption intentions for these unexpected-vegan products with a vegan label (vs. no label). Importantly, this applies to both utilitarian and hedonic products. No effects attributed to the vegan label (vs. no label) were found for randomly-vegan products that consumers expected to be vegan by default.

Abstract
Despite the established health and ecological benefits of a plant-based diet, the decision to eschew meat and other animal-derived food products remains controversial. So polarising is this topic that anti-vegan communities - groups of individuals who stand vehemently against veganism - have sprung up across the internet. Much scholarship on veganism characterizes anti-vegans in passing, painting them as ill-informed, uneducated, or simply obstinate. However, little empirical work has investigated these communities and the individuals within them. Accordingly, we conducted a study using social media data from the popular platform, Reddit. Specifically, we collected all available submissions (∼3523) and comments (∼45,528) from r/AntiVegan subreddit users (N = 3819) over a five-year period. Using a battery of computerized text analytic tools, we examined the psychosocial characteristics of Reddit users who publicly identify as anti-vegan, how r/AntiVegan users discuss their beliefs, and how the individual user changes as a function of community membership. Results from our analyses suggest several individual differences that align r/AntiVegan users with the community, including dark entertainment, ex-veganism and science denial. Several topics were extensively discussed by r/AntiVegan members, including nuanced discourse on the ethicality and health implications of vegan diets, and the naturalness of animal death, which ran counter to our expectations and lay stereotypes of r/AntiVegan users. Finally, several longitudinal changes in language use were observed within the community, reflecting enhanced group commitment over time, including an increase in group-focused language and a decrease in cognitive processing. Implications for vegan-nonvegan relations are discussed.

Abstract
In recent years, and in the current climate crisis, the interest in veganism and sustainable diet/lifestyle has increased. This growing interest can also be seen within academia. Therefore, we set out to systematically document and organize the social psychological literature on veganism and vegan identity to identify where the field currently is, and what we need to do next. Following PRISMA guidelines we identified a data set of 26 academic papers published between 2010 and 2021. Through a thematic analysis of the data, we created four categories of study focus and content: (1) vegans as a disadvantaged/stigmatized group, (2) the role of ideology in negative attitudes toward vegans, (3) the role of moral and ethical beliefs in changing or sustaining dietary preferences, and (4) veganism as a social movement and vegan activism. Our analysis emphasizes issues with merging all non-meat eaters, reduction of veganism into dietary or lifestyle choices neglecting the politicized content and movement, lack of processes underlying emergence and endurance of veganism, and decontextualization of vegan identity. What is needed is a more fine-grained exploration that addresses the identified issues to account for the content of vegan identity. This would expand, for example, the motives literature to include and emphasize intersectionality in a vegan identity context. Specifically, to facilitate a more sustainable lifestyle, the content of social dimensions needs to be qualitatively explored.

Abstract
Empirical studies have persistently reported negative attitudes of meat eaters toward vegetarians and vegans (veg*ns), but scant attention has been paid to veg*ns' attitudes toward meat eaters. We aimed to investigate the attitudes of meat eaters and veg*ns from both perspectives. In addition, we explored the attitudes of occasional meat eaters. We performed a cross-sectional study (Study 1) among meat eaters, veg*ns, and occasional meat eaters, as well as a content analysis of publicly available tweets (Study 2). Study 1 (N = 477, Mage = 23.45, SD = 5.91) showed that the attitudes of veg*ns toward meat eaters are significantly more negative compared to the attitudes of meat eaters toward veg*ns, but both were lower than the midpoint on scales measuring negative attitudes toward the other. Study 2 showed that only a small portion (<1%) of tweets (N = 1,328) on meat eating or veg*nism contained signs of negative attitudes. The two studies provide little evidence of the existence of strong negative attitudes.

Abstract
Adopting a plant-rich or plant-based diet is one of the major recommendations for addressing obesity, overweight, and related health conditions in the United States. Currently, research on African Americans' food choices in the context of plant-based diets is limited. The primary aim of this study was to understand food-related experiences and perceptions of African Americans who were participating in the Nutritious Eating with Soul (NEW Soul) study, a culturally tailored dietary intervention focused on increasing the consumption of plant-based foods. The roles of gender and ethnicity were also examined to identify how eating patterns were chosen or maintained. Twenty-one African American adults in South Carolina, who were randomly assigned to either a vegan diet (n = 11) or a low-fat omnivorous diet (n = 10) in the NEW Soul study, completed one-on-one, qualitative interviews. Emerging themes included awareness, being in control, and identity. The study revealed that access to social support and coping strategies for addressing negative comments about plant-based food choices may be important components to include in future nutrition interventions focused on African Americans.

Abstract
Switching out meat in favour of plant-based alternatives such as meat substitutes is an important step towards eating more sustainably. Here, the aim was to identify and explore the specific barriers experienced by Swedish consumers when replacing meat with more sustainable alternatives. All meat-eating participants in this study reported some interest in reducing their meat consumption. Aspects of home-use and central-location test methods were combined by using a digital conferencing system to host cooking sessions and focus group discussions online, which was shown to be a viable setup even in this hands-on setting. The discussions targeted participants' experience preparing meals using meat substitutes as well as their perceived motivators and barriers to reducing meat consumption. Four themes identified through thematic analysis indicated that meat-eating participants, despite their desire or intent to reduce their meat consumption, experienced barriers relating to the following: internal conflict due to holding multiple positive and negative beliefs about meat simultaneously (ambivalence), justification of eating meat (rationalisation), a desire for variety in and control over their food choices (agency), and sensitivity to the views and expectations of other people and the situational context regarding meat (social and structuralfactors). Possible strategies to support ambivalent individuals in aligning their behaviour with their beliefs instead of vice versa are discussed in the context of the meat paradox. Agency and practical skills, including increasing knowledge in preparing meals with plant-based proteins, likely play a role in bridging this intention-behaviour gap.
