RESUMO

Adding to research on the form and content of anti-vegan sentiment, recent scholarship has identified a group of individuals who self-subscribe as "anti-vegan". Here, we sought to determine whether anti-veganism might reflect a distinct dietarian identity with its own unique ideological profile. Two-hundred and fourteen vegans, 732 omnivores, and 222 self-identified "anti-vegans" were assessed using a survey methodology that included the Dietarian Identity Questionnaire and ideological markers related to dark humour, social dominance orientation (SDO), speciesism, male-role norms, moral relativism, and attitudes toward science. Our analysis revealed a dietarian identity unique to anti-vegans. The dietary patterns of anti-vegans were more central to their identity than for omnivores, though marginally lower than vegans. Like vegans, anti-vegans scored highly on dietarian measures of private regard and personal dietary motivations, and lower than omnivores on public regard. The diets of anti-vegans were more morally motivated than omnivores. However, anti-vegans scored higher than both omnivores and vegans on a number of ideological measures including dark humour, SDO, speciesism, male-role norms, moral relativism, and distrust of science. Somewhat surprising, anti-vegans held greater trust than omnivores in the science of plant-based nutrition. We discuss the unique dietarian identities of anti-vegans, considering both intra-group differences of omnivores and anti-vegans (e.g., in right-wing ideology), and inter-group similarities of vegans and anti-vegans (e.g., in diet centrality).

RESUMO

Social media is an increasingly important yet understudied context for eating behaviors in general and veganism in particular. In four studies, we first explored and described the information environment the platform Instagram presents related to veganism. Second, we examined how engaging with this environment is associated with offline eating intentions via psychological mechanisms. We scraped datasets of Instagram posts tagged with #vegan (44,316 posts in total) and employed network analysis with their hashtags (Study 1), as well as clustering with images and sentiment analysis with texts (Study 2). Studies 3 (N = 117) and 4 (N = 251) used online surveys to investigate associations between different forms of engaging with social media content, psychological constructs, and offline eating intentions. Posts about veganism were frequently related to food, health and fitness, cosmetics, and photography. Images most often depicted food (34.7%), non-food products (30.4%), people (7.9%), and animals (2.0%). The sentiment of most posts was positive. Being exposed to Instagram content about veganism was more strongly and consistently associated with eating intentions than active forms of engagement. Attitude and self-identity emerged as the most relevant mechanisms for these effects. Food is the most prominent yet not sole topic among posts about veganism on Instagram, and hashtags used in this context partially relate to motives for following a vegan diet. Exposure to this information environment might influence offline eating decisions via psychological mechanisms. With growing usage and its potential influence, social media should receive increasing attention in (health) psychological research and practice.

RESUMO

Vegetarianism is growing dramatically among adolescents and young adults. Professionals specialized in eating disorders (ED) may routinely face patients adhering to these popular vegetarian practices. This qualitative study aimed to investigate healthcare professionals' subjective experience of vegetarianism in ED patients. Interviews of practitioners specialized in ED, recruited from the French federation of anorexia and bulimia (FFAB), were conducted using a semi-structured guide. We reached data saturation. Thematic analysis was used to identify and analyze patterns of meaning in the dataset. Eighteen professionals (dieticians, physician-nutritionists, and a psychiatrist) with private or institutional practices were interviewed. Three meta-themes emerged from our thematic analysis: (1) heterogeneous perceptions of vegetarianism among healthcare professionals, (2) diverse nutritional care practices, (3) factors influencing professionals' nutritional strategies and approaches. This original qualitative and exploratory study reported vegetarianism is a fast-growing phenomenon observed in a majority of adolescent patients with anorexia nervosa, with various underlying motivations reported. In all cases, the nature of the timing and relation between the vegetarian practices and the ED should be carefully assessed, using specific tools. Because of the ethical dimension of this issue and the risk of professional bias, institutional policy based on specific practice guidelines, to be developed, are strongly encouraged.

RESUMO

The dietary choices of male athletes are increasingly a topic of moral and nutritional debate. Though it has long been a consensus that athletes require animal products to advance their athletic goals, this understanding is now challenged in academic and popular sources based on nutritional evidence and concern about the environmental impacts of animal products. In order to better understand how (semi-)professional male athletes perceive plant-based diets and diets containing animal products, thirteen semi-structured interviews were conducted with male athletes competing nationally and internationally, including mixed and plant-based eaters. Interviews were analysed through reflexive thematic analysis, in line with a critical, qualitative research methodology. Justifications for meat, situated knowledge and masculinity were used as theoretical lenses. Our analysis shows how athletes reproduce nutritional claims about the necessity of protein for athletes, but disagree on the suitability of plant-based sources. This nutritional discourse derives from a broad range of sources, including professional nutritionists, friends, online influencers, and media. Second, when explaining their own food practices, food being 'nice' and 'normal' - common justifications for meat as evidenced in the 4N theory - often supersede necessity. Embedding these views in their everyday lives as athletes shows that food environments and shared eating practices fortify a mixed diet as normal, and plant-based diets as anomalous. It further shows how the view of meat being normal is subject to shifting masculinity norms. Interviewees reject meat eating as normal and masculine for men, while male athletes who show dedication, constraint, and knowledge in a plant-based diet are viewed positively. As role models for diet and masculinity, this has implications for a potential role of athletes in a societal transition towards lower consumption of animal products.

RESUMO

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.

RESUMO

Background: The number of vegans in the world is growing and in Slovakia and the Czech Republic they make up 1% of the population. Vegan diet excludes all foods of animal origin and vegans who do not use vitamin B12 supplements are at risk of the vitamin B12 deficiency. Objective: The aim of this study was to determine what proportion of Czech and Slovak vegans use vitamin B12 supplements regularly, irregularly or not at all and what is their supplemental cobalamin intake. Materials and methods: The research involved 1337 self-identified vegans from Slovakia and the Czech Republic who were interviewed using the CAWI (Computer-Assisted Web Interview) method. Participants were recruited by posts in veganism-themed social media groups. Results: Out of 1337 vegans 55.5% supplemented cobalamin regularly, 32.54% irregularly and 11.97% were not supplementing. Rate of not supplementing individuals was 5.04% higher in Slovaks than in Czechs. Short-term vegans had a significantly higher rate of not supplementing individuals (17.99%) compared to medium-term (8.37%) and long-term vegans (7.50%). Mean weekly cobalamin intake from supplements was 2938.34±2566.60 µg in regularly supplementing vegans compared to 1630.31±1949.27 µg in irregularly supplementing vegans, particularly due to the lower weekly supplementation frequency among irregularly (2.93) compared to regularly supplementing vegans (5.27). Conclusions: The rate of supplementation in Slovak and particularly Czech vegans was higher than in other countries. The number of not supplementing individuals was significantly higher among short-term vegans, indicating that there is still a need for education on the importance of adequate and regular cobalamin supplementation, especially in new vegans. Our results support the hypothesis that the reason for higher rate of cobalamin deficiency in irregularly compared to regularly supplementing vegans is the lower cobalamin intake caused by lower supplementation frequency.

RESUMO

Claims that consumption of phytate-rich grains, by definition, worsens mineral status needs to be clarified as new evidence emerges about the role of phytic acids (FA) from whole grains in improving population health outcomes. In this regard, it seems appropriate to draw the attention of practitioners to the need to correct patient's diet in order to prevent non-communicable diseases. The aim of this review was to generalize and analyze the modern data on the role of phytates in human nutrition. Material and methods. A search for domestic and foreign literature in the bibliographic databases of articles on medical sciences was carried out using the PubMed, MEDLINE and eLibrary search engines. Results. Deficit of minerals and trace elements in the diet, especially deficiency of iron, calcium, selenium, zinc, iodine, is an urgent public health problem in many countries. Calcium, magnesium, zinc, selenium, and iron deficiencies are associated with impaired immune function and an increased risk of both acute and chronic diseases. Vegan and vegetarian behavior styles with the restriction and exclusion of animal sources of bioavailable minerals and trace elements are gaining more and more popularity in our country. FA is the main storage form of phosphorus in nuts, grains, legumes, and seeds, which satisfies the biosynthesis needs of growing tissues during germination. FA is known as a dietary inhibitor that chelates minerals and trace elements, limiting their bioavailability and reducing their absorption. Pre-treatment methods to reduce phytate levels and increase the nutritional value of diets are fermentation, soaking, and sprouting. Reducing phytate content in plant foods by processing leads to a measurable improvement in mineral status, however, the chelating and antioxidant properties of phytates may be beneficial and their potential in the prevention of cancer, cardiovascular disease, diabetes mellitus and kidney stone formation is currently being studied. Conclusion. Essential components of a healthy diet are whole whole grains, legumes, vegetables, seeds and nuts, despite the fact that most of them are relatively high in FA. Despite some antinutrient properties, FAs have preventive effects on public health.

RESUMO

Since the beginning of the 21st century, interest in vegan diets has been rapidly increasing in most countries. Misconceptions about vegan diets are widespread among the general population and health professionals. Vegan diets can be health-promoting and may offer certain important advantages compared to typical Western (and other mainstream) eating patterns. However, adequate dietary sources/supplements of nutrients of focus specific to vegan diets should be identified and communicated. Without supplements/fortified foods, severe vitamin B12 deficiency may occur. Other potential nutrients of focus are calcium, vitamin D, iodine, omega-3 fatty acids, iron, zinc, selenium, vitamin A, and protein. Ensuring adequate nutrient status is particularly important during pregnancy, lactation, infancy, and childhood. Health professionals are often expected to be able to provide advice on the topic of vegan nutrition, but a precise and practical vegan nutrition guide for health professionals is lacking. Consequently, it is important and urgent to provide such a set of dietary recommendations. It is the aim of this article to provide vegan nutrition guidelines, based on current evidence, which can easily be communicated to vegan patients/clients, with the goal of ensuring adequate nutrient status in vegans.

RESUMO

PURPOSE: It has been estimated that most vegans meet the total protein requirements, but whether this is also true for individual essential amino acids (AAs) is unclear. Furthermore, a shift in protein intake is suggested to alter microbiota composition, but this association is unknown in terms of veganism or individual AAs. This cross-sectional study compared vegans and omnivores regarding dietary intake and plasma concentration of AAs. The prevalence of insufficient intake of essential AAs among vegans was determined using estimated average requirements (EAR) of WHO. Moreover, correlations between AAs intake and gut microbiota were investigated. METHODS: Data of 36 vegans and 36 omnivores (30-60 years) were analysed. AA intake, AA plasma concentrations and gut microbiota were ascertained by three-day weighed food protocols, gas/liquid chromatography-tandem mass spectrometry and 16S rRNA sequencing, respectively. RESULTS: At almost the same energy intake, the intake of 9 AAs in vegans was significantly lower than in omnivores, with median differences of - 27.0% to - 51.9%. However, only one female vegan showed total protein and lysine intake below the EAR. Vegans showed lower lysine (- 25.0%), but higher glycine (+ 25.4%) and glutamate (+ 13.1%) plasma concentrations than omnivores. Correlation patterns between AA intake and bacterial microbiota differed between vegans and omnivores. In vegans 19 species and in omnivores 5 species showed correlations with AA intake. CONCLUSION: Vegans consumed apparently sufficient but lower AAs than omnivores. In addition, the different AAs intake seems to influence the microbiota composition. The use of short-term dietary data without considering usual intake limits these findings.

RESUMO

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.

RESUMO

Previous work identified the operation of an attentional bias (AB) towards healthy food related stimuli among those with increasing tendencies towards orthorexia nervosa (ON) using a modified Stroop task. The current work aimed to replicate and extend our understanding of this effect by incorporating alternative measures of AB (i.e., the dot probe task) and ON (i.e., the Teruel Orthorexia Scale [ToS]) in a sample of self-defined vegans/vegetarians. The theoretical assertion of the ToS is the conceptual broadening of orthorexia with differentiable dimensions - one characterised as a "healthy" preoccupation with healthy food/eating patterns (HeOr) and the other by a more underlying pathology (OrNe). This study also aimed to examine the pattern of responding across these two dimensions according to factors known to predict ON. Eighty-six participants (mean age = 33.0 years; 20 males, 66 females) completed measures of obsessive compulsivity, perfectionism, state/trait anxiety and ToS as well as a dot probe designed to measure AB for healthy and unhealthy-related food stimuli, threat ratings of each of words utilized and perceived identity centrality as a vegan/vegetarianism. Results showed a dissociation of predicted determinants for "healthy" ON (HeOr) and pathological ON (OrNe). HeOr was predicted by increasing identity centrality whereas OrNe was predicted by increased OCD and perfectionism, and increased interference for healthy-related food words (in particular slowed disengagement) and not unhealthy related food words. Threat-related ratings of unhealthy food words was shown to be common across both dimensions. This pattern highlights cognitive and individual differences-based correlates of pathological and non-pathological ON.

RESUMO

Adopting plant-based, or vegan, diets can have a number of benefits, including mitigating climate change, promoting animal welfare, or improving public health. In the current research, we use social psychological theory to better understand what motivates vegans to engage in collective action on behalf of this social group - that is, what motivates individuals to promote, or encourage others to adopt, a vegan lifestyle. We develop and test a Social Identity Model of Vegan Activism, which highlights the roles of individuals' social identities, sense of efficacy, emotions and moral convictions in fostering collective action. In two pre-registered studies, the first with self-identified vegans from Australia and the UK (N = 351), and the second with self-identified vegans from the UK and the US (N = 340), we found that individuals more frequently engaged in vegan activism (i.e., actions to promote vegan lifestyles) when they had stronger moral convictions (i.e., deontological or consequentialist), greater collective efficacy (i.e., beliefs that vegans can make a positive difference), anger (i.e., when thinking about the reasons why they are vegan), and identification (both with vegans, and with animals). Deontological and consequentialist moral convictions had significant indirect effects on vegan activism via different mediators. We conclude by discussing the implications and importance of studying dietary behavior from a social identity perspective, including its ability to help explain how and why individuals become motivated to not only adopt a certain (e.g., vegan) lifestyle themselves, but to also 'act collectively' on behalf of that shared group membership (e.g., promote vegan-friendly behaviors). We also highlight some key insights for policy makers and campaigners aiming to promote plant-based diets.

RESUMO

PURPOSE: Meat avoidance has long been thought to be related to eating psychopathology; however, research does not necessarily support this notion. Furthermore, commonly used eating disorder scales may be picking up on normal meat-avoiding behaviours in vegetarians and vegans. As such, we systematically reviewed the association between vegetarianism, veganism, and disordered eating, and reviewed the psychometric properties of eating disorder scales for use in these populations. METHODS: We searched electronic databases MEDLINE, PsychINFO, and CINAHL for literature published until June 2021. RESULTS: Forty-eight studies met eligibility criteria, with no consensus as to whether meat avoidance was associated with higher rates of disordered eating. Most studies reported a significant positive association with both vegetarianism and veganism, and orthorexia nervosa. Six studies provided evidence for the use of eating disorder measures in vegetarians and vegans, reporting poor psychometric fit among all scales. CONCLUSION: This systematic review highlights the extent to which vegetarians and vegans have been highly understudied, with limited research suggesting higher levels of orthorexia nervosa behaviours in vegetarians and vegans. Furthermore, our results provide tentative evidence that the factorial validity of commonly used eating disorder scales, such as the EDE-Q, may be poor in vegans. LEVEL OF EVIDENCE: Level I, systematic review.

RESUMO

Veganism is a form of nutrition that is becoming increasingly popular. There is also a pandemic-related increase in mental illness, which often manifests itself in the form of an eating disorder among children and adolescents. Particularly challenging in nutritional therapy is anorexia nervosa in combination with veganism.There is consensus that a correctly implemented vegan diet can generally cover the daily nutritional requirements. However, this does not apply to people who are in a growth period. Therefore, this article attempts to highlight the special requirements of a vegan diet along the dietary process development.The basis is provided by a specific anamnesis as well as the elicitation of nutritional status by means of nutrition protocol and bioelectrical impedance analysis. The treatment and goal setting are influenced by the motives behind a vegan diet and further diagnoses such as orthorexia or food intolerance. Regarding the course of action, it must be clarified how an adequate vegan diet can be guaranteed and which conditions are needed to create a space where different diets can be accepted simultaneously. Withing the daily care, nutritional aspects such as the reduction of anorexia-related digestive complaints as well as the selection, quantity and preparation of vegan foods are foregrounded. This is illustrated by nutritional analyses. The objective is to achieve a high level of compliance and to ensure a sufficient nutrient supply in order to make food, as well as vegan food, enjoyable.

RESUMO

OBJECTIVE: To explore adherence to a plant-based diet from the perspective of goals- and motivations-based systems. DESIGN: A cross-sectional, survey-based study was conducted regarding eating patterns, goals and motivations for current eating habits. SETTING: Data were collected using an online survey platform, including the Goal Systems Assessment Battery (GSAB) and other survey tools. PARTICIPANTS: University students were recruited, including thirty-three students reporting successful maintenance of a plant-based diet (Adherents) and sixty-three students trying to adhere to a plant-based diet (Non-adherents). RESULTS: Using GSAB subscale scores, discriminant function analyses significantly differentiated adherents v. non-adherents, accounting for 49·0 % of between-group variance (χ2 (13) = 42·03, P < 0·000). It correctly classified 72·7 % of adherents and 88·9 % of non-adherents. Constructs including value, self-efficacy, planning/stimulus control and positive affect were significant and included in the discriminant function. Logistic regression results suggested that participants who successfully adhered to a plant-based diet were seventeen times more likely to report 'To manage or treat a medical condition' as motivation and almost seven times more likely to report 'To align with my ethical beliefs' as motivation compared with non-adherents. However, these participants were 94 % less likely to report 'To maintain and/or improve my health' as motivation compared with non-adherents. Controlling for motivations, hierarchical logistic regression showed that only planning as part of the GSAB self-regulatory system predicted adherence to a plant-based diet. CONCLUSIONS: Values-based approaches to plant-based diets, including consideration for ethical beliefs, self-efficacy and proper planning, may be key for successful maintenance of this diet long-term.

RESUMO

With rates of vegetarianism and veganism (i.e., veg*nism) rising around the world, a growing body of research has begun to explore psychological characteristics that distinguish vegetarians and vegans from omnivores. However, relatively few studies have examined how veg*nism is related to differences in basic personality traits such as the "Big Five", with those that have tending to yield conflicting results. Moreover, none of these studies have examined personality at the lower levels of the personality trait hierarchy (i.e., aspects and facets of the Big Five). Thus, we sought to clarify how personality traits are related to veg*nism. In Study 1, comprising two samples (S1a: N = 797, S1b: N = 1534), participants were categorised as Veg*n vs Restricted-omnivore vs Omnivore, and completed personality questionnaires at the domain and aspect levels of the Big Five. In Study 2, participants (N = 562) completed both categorical and continuous measures of veg*nism, along with personality questionnaires at the domain, aspect, and facet levels. Across both studies, we found that people who scored higher on traits within the openness/intellect and agreeableness domains most consistently reported higher levels of veg*nism. Patterns in the data also suggested that the relation between personality and veg*nism might depend on the way veg*nism is measured. Theoretical and practical implications of these findings are discussed.

RESUMO

Concerns over potential negative effects of excessive meat consumption on both the environment and personal health, coupled with long-standing debates over animal rights, have motivated research on the prevalence and predictors of plant-based versus meat-based diets. Yet few studies have examined longitudinal trends in dietary behaviours using large national samples. We address this gap by examining the prevalence, predictors, and annual change in the self-reported dietary behaviour of a large national probability sample of New Zealand adults (categorised as omnivore, vegetarian, or vegan; Ns = 12,259-50,964). Consistent with our pre-registered hypotheses, omnivore was the most prevalent dietary category (94.1%). Moreover, higher levels of conservative ideologies (i.e., political conservatism, Right-Wing Authoritarianism, and Social Dominance Orientation), lower subjective health, lower environmental efficacy, and lower disgust sensitivity predicted having an omnivore (vs. vegetarian or vegan) diet. Longitudinal analyses further revealed that the probability of shifting from an omnivore diet to a vegetarian or vegan diet over a one-year period was low, and that veganism was the least stable dietary category. Both gender (men) and political conservatism predicted lower probabilities of transitioning from meat to no-meat diets over time.

RESUMO

Despite the strength of arguments for veganism in the animal rights literature, alongside environmental and other anthropocentric concerns posed by industrialised animal agriculture, veganism remains only a minority standpoint. In this paper, I explore the moral motivational problem of veganism from the perspectives of moral psychology and political false consciousness. I argue that a novel interpretation of the post-Marxist notion of political false consciousness may help to make sense of the widespread refusal to shift towards veganism. Specifically, the notion of false consciousness fills some explanatory gaps left by the moral psychological notion of akrasia, often understood to refer to a weakness of will. Central to my approach is the idea that animal exploitation is largely systemic and the assumption that moral motivation is inseparable from moral thinking. In this light, the primary obstacle to the adoption of veganism arises not so much from a failure to put genuine beliefs into action, but rather in a shared, distorted way of thinking about animals. Thus, common unreflective objections to veganism may be said to be manifestations of false consciousness.

RESUMO

This paper describes a pair of dietary practices I label default vegetarianism and default veganism. The basic idea is that one adopts a default of adhering to vegetarian and vegan diets, with periodic exceptions. While I do not exhaustively defend either of these dietary practices as morally required, I do suggest that they are more promising than other dietary practices that are normally discussed like strict veganism and vegetarianism. For they may do a better job of striking a balance between normative concerns about contemporary farming practices and competing considerations of life. Additionally, I argue that framing discussions in terms of defaults is useful for various reasons: it helps organize agreements and disagreements, it more accurately reflects the way people conceptualize their dietary practices, and it presents a more dialectically effective view.

RESUMO

Vegan feminist theory argues that women and other marginalized groups frequently experience discrimination in the vegan movement given its failure to apply intersectional praxis. We interviewed a small sample of older vegan women in America, hypothesizing that they would report feeling particularly vulnerable to discrimination given the vegan movement's patriarchal leanings and its heavy focus on health and vitality. Our results, however, are mixed. Some viewed older age as an asset that strengthened their ability to commit to veganism, while others reported stressed social interactions, underrepresentation in the movement, and lack of support by doctors.
