RESUMO

Vegetarian and vegan (Veg*n) diets are increasingly popular in Western societies and an increasingly common topic of psychological research. Animal-free diets hold considerable potential for helping curb the climate crisis and improving interspecies justice. This special issue presents recent contributions from research on the psychology of meat eating and veg*nism. To situate these articles in a broader context, we first establish the importance of studying veg*nism. We then review papers in this special issue, organized into themes of motivations and characteristics of veg*ns, attitudes towards veg*ns, attitudes toward meat and alternative proteins, intentions to eat meat or plant-based foods, consumption of meat or plant-based foods, and meat reduction interventions. We conclude with future directions for this blossoming field of study.

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

OBJECTIVE: Veganism may serve as a socially acceptable means to restrict food intake and disguise pathological eating behaviours. Studies that include vegan participants typically group them with other meat avoiders (e.g., vegetarians), potentially masking risk factors unique to veganism. METHOD: We addressed this issue by recruiting two Amazon Mechanical Turk samples of 110 vegan and 118 omnivore participants, with comparable gender composition. We aimed to examine whether vegans showed higher disordered eating than omnivores, and if motives for pursuing a vegan diet impacted disordered eating. We assessed disordered eating using the Eating Attitudes Test, the Eating Disorder Examination-Questionnaire, and the Eating Pathology Symptom Inventory. RESULTS: Vegans displayed more pathological eating behaviours than omnivores, which was significantly predicted by cognitive restraint. However, body dissatisfaction levels were higher in omnivores than vegans. Diet motives did not influence vegans' disordered eating. CONCLUSION: We propose vegans have high levels of cognitive restraint, possibly due to their intention to avoid animal products. In turn, cognitive restraint subscales in eating disorder measures might be over-pathologising rates of eating disorders in vegans. Future research should monitor the progression of people's eating-related attitudes and behaviours before and after they transition to veganism to establish whether veganism increases the risk of disordered eating, or vice versa. LEVEL OF EVIDENCE: IV, cross-sectional study.

RESUMO

This study aimed to evaluate the general quality of life (QoL) of Brazilian vegetarians. A cross-sectional study was conducted with Brazilian vegetarian adults (18 years old and above). Individuals were recruited to participate in a nationwide online survey that comprised the WHOQOL-BREF as well as sociodemographic and characterization questions related to vegetarianism. The WHOQOL-BREF is composed of 24 items which are divided into four domains (domain 1: physical health; domain 2: psychological well-being; domain 3: social relationships; and domain 4: environment), plus two general items which were analyzed separately, totaling 26 items. The answers from the questionnaire were converted into scores with a 0-100 scale range, with separate analyses for each domain. Results were compared among groups based on the different characteristics of the vegetarian population. A total of 4375 individuals completed the survey. General average score results were 74.67 (domain 1), 66.71 (domain 2), 63.66 (domain 3) and 65.76 (domain 4). Vegans showed better scores when compared to the other vegetarians, except in domain four, where the statistical difference was observed only for semi-vegetarians (lower score). Individuals adopting a vegetarian diet for longer (>1 year) showed better results for domains one and two, with no difference for the other domains. Having close people also adopting a vegetarian diet positively influenced the results for all domains. On the other hand, it was not possible to distinguish any clear influence of the motivation for adopting a vegetarian diet on the scores' results. Adopting a vegetarian diet does not have detrimental effects on one's QoL. In fact, the more plant-based the diet, and the longer it was adopted, the better the results were.

RESUMO

CONTEXT: Vegetarian and vegan diets are increasing in popularity. Although they provide beneficial health effects, they may also lead to nutritional deficiencies. Cognitive impairment and mental health disorders have a high economic burden. OBJECTIVE: A meta-analysis was conducted to examine the relationship between vegan or vegetarian diets and cognitive and mental health. DATA SOURCES: PubMed, Scopus, ScienceDirect, and Proquest databases were examined from inception to July 2018. STUDY SELECTION: Original observational or interventional human studies of vegan/vegetarian diets were selected independently by 2 authors. DATA EXTRACTION: Raw means and standard deviations were used as continuous outcomes, while numbers of events were used as categorical outcomes. RESULTS: Of 1249 publications identified, 13 were included, with 17 809 individuals in total. No significant association was found between diet and the continuous depression score, stress, well-being, or cognitive impairment. Vegans/vegetarians were at increased risk for depression (odds ratio = 2.142; 95%CI, 1.105-4.148) and had lower anxiety scores (mean difference = -0.847; 95%CI, -1.677 to -0.018). Heterogeneity was large, and thus subgroup analyses showed numerous differences. CONCLUSIONS: Vegan or vegetarian diets were related to a higher risk of depression and lower anxiety scores, but no differences for other outcomes were found. Subgroup analyses of anxiety showed a higher risk of anxiety, mainly in participants under 26 years of age and in studies with a higher quality. More studies with better overall quality are needed to make clear positive or negative associations. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42018097204.

RESUMO

Orthorexia nervosa (ON) has been defined as an obsessive and pathological attitude towards healthy nutrition. The aim of this study was to compare individuals who followed a vegan, vegetarian, and omnivore diet in terms of ON behaviors and to examine their prime motivations, attitudes, and behaviors towards food. The Spanish version of the ORTO-15 test - ORTO-11-ES - and the Food Choice Questionnaire (FCQ-SP) were used with a demographic questionnaire in an online survey disseminated among the social networks of different vegetarian associations and the general population. Of 466 individuals, 55% followed an omnivore diet, 23.5% were vegetarian and 21.7% were vegan. Results revealed relationships between type of diet and FCQ-SP dimensions for: health and natural content (H = 8.7, p < 0.05), sensory appeal (H = 11.4, p < 0.01), weight control (H = 40.4, p < 0.01), and familiarity (H = 37.3, p < 0.01). Our results confirm the findings of recent studies showing that individuals who follow a vegan or vegetarian diet are more likely to develop a pathological preoccupation with healthy eating versus omnivores. Further studies are required to determine the potential lines of action for the prevention of ON.

RESUMO

O vegetarianismo é uma prática que exclui carnes e pode evitar outros produtos de origem animal. Esta última modalidade está muito associada ao veganismo, uma filosofia que defende a libertação animal. Aderir a tais condições implica no seguimento de algumas normas que norteiam comportamentos alimentares e interações sociais. Partindo desse pressuposto, objetivou-se avaliar o nível de concordância, entre vegetarianos e veganos, quanto a regras que descrevem comportamentos alimentares. A pesquisa contou com 398 participantes, sendo 198 não estritos e 200 estritos, que responderam a um questionário on-line autoaplicável. Os dados, analisados via teste t, apontaram maiores níveis de concordância com comportamentos mais restritos entre vegetarianos estritos e veganos os quais também relataram maior embasamento em valores. Este estudo, que trouxe uma ótica de análise para os comportamentos alimentares em termos de localização de reforços, pode contribuir com novas práticas em saúde direcionadas às pessoas vegetarianas e veganas.

Vegetarianism is a practice that excludes meat and can avoid other products of animal origin. This latter modality is closely associated with veganism, a philosophy that advocates animal liberation. Adherence to these conditions implies following some norms that guide eating behaviors and social interactions. Based on this assumption, we aimed to evaluate the agreement level, between vegetarians and vegans, regarding rules that describe food behaviors. The survey included 398 participants, 198 non-strict and 200 strict vegetarians, who answered a self-administered online questionnaire. The data, analyzed by t-test, showed higher agreement level with more restricted behaviors between strict vegetarians and vegans, who also reported a higher base on values. This study, which provided an analysis perspective on eating behaviors in terms of reinforcement location, may contribute to new health practices aimed at vegetarians and vegans. (AU)

RESUMO

There are a significant number of studies on cognitive restraint among individuals with varying dietary patterns. Although most research has found that vegetarians report higher levels of cognitive restraint compared to non-vegetarians, many studies have contributed inconsistent results. The aim of the current study, therefore, was to assess any differences between groups with varying dietary patterns on cognitive restraint and other disordered eating pattern. The second objective was to examine determinants of cognitive restraint in individuals adhering to a vegan diet, a vegetarian diet and an omnivore diet. Two-hundred and fifty-four participants with varying dietary patterns completed the Three-Factor Eating Questionnaire, the Perseverative Thinking Questionnaire and the Eating Habits Questionnaire. Our results indicated that both vegetarian and vegan groups showed a significantly lower cognitive restraint, lower emotional eating and lower uncontrolled eating than those who followed an omnivorous diet. In addition, these both groups following a plant-based diet have shown more cognitions, behaviours and feelings related to an extreme focus on healthy eating (orthorexia nervosa) than group following an omnivorous diet. There were no significant differences between the groups in perseverative thinking. Core characteristics of repetitive negative thinking was a significant predictor of cognitive restraint in vegans. Feeling positively about healthy eating predicted cognitive restraint among vegetarians. Problems associated with healthy eating and feeling positively about healthy eating predicted cognitive restraint among individuals following an omnivorous diet. Knowledge of predictors of cognitive restraint may serve as a psychological intervention goal or psychoeducation goal among individuals with varying dietary patterns.

RESUMO

The adoption of a vegetarian diet has been associated with positive health outcomes. However, few studies evaluate the effect of this eating pattern on quality of life. Moreover, no specific instrument for the vegetarian population to measure the quality of life is available worldwide. Therefore, this study aimed to elaborate and validate a specific questionnaire to measure the quality of life in vegetarians. The Specific Vegetarian Quality of Life Questionnaire (VEGQOL) was constructed based on other instruments and studies related to vegetarianism. The content and semantic validation were performed by a group of experts, followed by a pilot study to evaluate the questionnaire acceptability and reproducibility. Discriminant validation was tested using the WHOQOL as the gold standard measure (Pearson correlation ranging from 0.302 of the domain 3 to 0.392 of the domain 2). Afterward, a nationwide survey was conducted using VEGQOL. Content and semantic validation selected 19 of the initial 30 items. VEGQOL presented good reproducibility (Cohen's Kappa coefficient ranging from 0.361 to 0.730 and intraclass correlation coefficient of 0.820) and internal consistency (0.708), both adequate to evaluate the quality of life in vegetarians. The sample size (n = 5014 individuals, error of 3% at a level of significance of 5%) and distribution was representative of the Brazilian vegetarian population. In general, the quality of life of Brazilian vegetarians was considered satisfactory (VEGQOL cut off points 70-80). Among different types of vegetarians, the vegans showed better results with a VEGQOL mean value of 79.2 ± 10.7. Older individuals, the ones who adopted the diet for a longer time (VEGQOL mean value of 75.8 ± 12.7) and the ones who had other vegetarians in their social network (VEGQOL mean value of 74.6 ± 12.2) also had a better quality of life score. Individuals who adopted it for ethical or health reasons had a higher quality of life score. The questionnaire produced in this study is a useful tool for future research in this area. Results were better for vegans and for the ones who adopt the diet for ethical or health reasons.

RESUMO

Health, the environment, and animal rights represent the three main reasons people cite for vegetarian diet in Western societies. However, it has not been shown that these motives can be distinguished empirically, and little is known about what kind of people are likely to be compelled by these different motives. This study had three goals. First, we aimed to use construct validation to test whether develop health, environmental, and animal rights motives for a vegetarian diet could be distinguished. Second, we evaluated whether these motivations were associated with different demographic, behavioral, and personality profiles in three diverse samples. Third, we examined whether peoples' motivations were related to responses to vegetarian advocacy materials. We created the Vegetarian Eating Motives Inventory, a 15-item measure whose structure was invariant across three samples (N = 1006, 1004, 5478) and two languages (English and Dutch). Using this measure, we found that health was the most common motive for non-vegetarians to consider vegetarian diets and it had the broadest array of correlates, which primarily involved communal and agentic values. Correlates of environmental and animal rights motives were limited, but these motives were strong and specific predictors of advocacy materials in a fourth sample (N = 739). These results provide researchers with a useful tool for identifying vegetarian motives among both vegetarian and non-vegetarian respondents, offer useful insights into the nomological net of vegetarian motivations, and provide advocates with guidance about how to best target campaigns promoting a vegetarian diet.

RESUMO

Previous studies have shown that humans show an implicit approach bias toward food related items which is moderated by hunger and properties of the food items displayed (such as their palatability and calorie content). However, little is known about if and how this approach bias is moderated by food preferences and/or diet choices. In this study, we compared approach-avoidance biases in a group of young female omnivore and vegetarian eaters towards images of vegetarian and non-vegetarian food items using a manikin stimulus-response compatibility task. While vegetarian eaters showed a slightly larger approach bias for vegetarian than for non-vegetarian food stimuli, this bias was of similar size to that observed in the omnivorous group. Most interestingly, vegetarian eaters' approach bias towards non-vegetarian food pictures also did not differ from that of the omnivorous group, despite vegetarians rating those pictures as much less pleasant. Our findings suggest that approach biases towards food items are quite robust and do not rapidly change with dietary practice. However, despite approach biases often guiding behaviour, vegetarian eaters successfully withstand these implicit action tendencies and avoid non-vegetarian produce. Potential implications of this finding for the addiction literature are discussed.

RESUMO

Meat-eaters report that a number of barriers inhibit them from going vegetarian-for example, perceiving vegetarian diets to be inadequately nutritious, too expensive, unfamiliar, inconvenient, inadequately tasty, and socially stigmatizing. However, research identifying which barriers uniquely predict meat-eaters' openness to going vegetarian is lacking from the current literature. In the present research, accordingly, we conducted a highly powered, preregistered study (N = 579) to identify which barriers uniquely predict openness to going vegetarian. We focused specifically on anticipated vegetarian stigma, given recent qualitative evidence highlighting this attitude as an influential barrier. That is, do meat-eaters resist going vegetarian because they fear that following a vegetarian diet would make them feel stigmatized? Being of younger age, more politically conservative, White, and residing in a rural community predicted greater anticipated vegetarian stigma among meat-eaters. Frequentist and Bayesian analyses converged, however, to suggest that anticipated vegetarian stigma was not a significant predictor of openness to going vegetarian. The strongest predictors of openness were perceived tastiness and perceived healthfulness of vegetarian dieting. These factors-but not anticipated stigma-furthermore explained why men (compared to women) and political conservatives (compared to liberals) were particularly resistant to going vegetarian.

RESUMO

Shifting people in higher income countries toward more plant-based diets would protect the natural environment and improve population health. Research in other domains suggests altering the physical environments in which people make decisions ("nudging") holds promise for achieving socially desirable behavior change. Here, we examine the impact of attempting to nudge meal selection by increasing the proportion of vegetarian meals offered in a year-long large-scale series of observational and experimental field studies. Anonymized individual-level data from 94,644 meals purchased in 2017 were collected from 3 cafeterias at an English university. Doubling the proportion of vegetarian meals available from 25 to 50% (e.g., from 1 in 4 to 2 in 4 options) increased vegetarian meal sales (and decreased meat meal sales) by 14.9 and 14.5 percentage points in the observational study (2 cafeterias) and by 7.8 percentage points in the experimental study (1 cafeteria), equivalent to proportional increases in vegetarian meal sales of 61.8%, 78.8%, and 40.8%, respectively. Linking sales data to participants' previous meal purchases revealed that the largest effects were found in the quartile of diners with the lowest prior levels of vegetarian meal selection. Moreover, serving more vegetarian options had little impact on overall sales and did not lead to detectable rebound effects: Vegetarian sales were not lower at other mealtimes. These results provide robust evidence to support the potential for simple changes to catering practices to make an important contribution to achieving more sustainable diets at the population level.

RESUMO

We examined the associations between perceived discrimination, social identity need satisfaction, and well-being among a sample of vegetarians and vegans (veg*ns) in Turkey. Drawing on the Rejection Identification Model, Motivated Identity Construction Theory, and the Social Cure approach, we tested whether perceived discrimination was related to the satisfaction of esteem, meaning, belonging, efficacy, distinctiveness, and continuity needs derived from veg*n group membership and whether the satisfaction of these needs, in turn, was associated with psychological well-being and self-esteem. A total of 350 veg*ns living in Turkey participated in an online study and completed measures of perceived discrimination based on veg*n group membership, veg*n identity need satisfaction, psychological well-being, and global level self-esteem. As expected, perceived discrimination was prevalent among Turkish veg*ns (more so among vegans) and was strongly associated with the greater satisfaction of all identity needs. In turn, the satisfaction of efficacy and continuity needs was related to greater well-being, showing an indirect association between perceived discrimination and well-being. Findings also showed that the satisfaction of the esteem need predicted (less strongly) lower levels of psychological well-being and self-esteem, indicating only some aspects of need satisfaction through veg*n identities to have positive implications for well-being. Findings are discussed in terms of the relevant socio-cultural environment, social identity theories, and stigmatization in the context of veg*n group membership.

RESUMO

Many people who self-identify as vegetarian actually eat meat on occasion. Surveys documenting this phenomenon have become abundant over the past two decades, and recent studies have begun to explain why some vegetarians are more likely to violate their diets than others are. However, qualitative research detailing the experiences of vegetarians eating meat is sparse. In the current study, we surveyed 243 vegetarians, 124 (51%) of whom indicated that they have eaten meat since going vegetarian. Of these 124 participants, 108 provided written narratives about their experiences eating meat, which we analyzed. Participants were most likely to eat meat at family gatherings and on special occasions; to eat meat in order to make a social situation flow more smoothly; and to react negatively to having eaten meat. Participants' narratives suggest that vegetarianism may be best conceived as a social identity, beyond just a diet. Some vegetarians reported that they view their diets as flexible guidelines, rather than rigid rules they ought to follow without exception. This study is the first, to our knowledge, to document in detail how vegetarians reflect on their experiences eating meat.

RESUMO

Our aim was to study Brazilian consumer attitudes towards cell-based meat and related issues. From 408 respondents from Curitiba and 218 from Joinville, the majority was women with higher level of education; 65.2% and 70.2% frequently consumed meat and 50.7% and 50.9% would not stop eating meat; 81.6% and 82.6% had little or no knowledge about cell-based meat. After watching an explanatory video, 41.9% and 34.4% stated they would eat cell-based meat without restrictions; 24.5% and 23.9% stated they would try depending on conditionals. Overall, 63.6% declared they would eat cell-based meat; among vegetarians and vegans, 24% and 8% stated they would eat cell-based meat, with additional 25.0% and 27.0% stating "it depends"; thus, the major public for cell-based meat seems to be meat eaters. Animal welfare was the principal reason for considering not eating meat and a major benefit of cell-based meat. In conclusion, the majority of respondents would not stop eating meat; additionally, they would eat cell-based meat.

RESUMO

Recent studies have found values for animal-welfare, personal-health and the environment to be the main factors motivating veg*n diets. However, studies are yet to simultaneously compare these values between Australian meat-eaters, vegetarians, and vegans, and therefore, the extent to which they motivate these groups. Further, while cognitive mechanisms (methods of reducing the psychological discomfort of eating meat while holding such values) have been found to facilitate meat intake, these mechanisms are yet to be compared against values in their ability to predict meat consumption. In the current study, meat-eaters reported the lowest concern for animal-welfare, personal-health, and the environment. With the exception of personal-health, vegans reported the greatest concern for these factors. However, cognitive mechanisms predicted meat consumption more strongly than these values. These findings may have implications for reducing meat consumption and improving outcomes for animal-welfare, public health and the environment.

RESUMO

The present study investigated cognitive reappraisal during exposure to vegetarian and nonvegetarian food cues in food-deprived vegetarian and omnivore participants. In particular, we were interested in clarifying the motivational meaning of the foods that vegetarians avoid, as revealed by self-reported food craving, valence, and arousal, as well as by ERP measures of neural processing during passive viewing and emotional regulation. Twenty-four vegetarians and twenty-one omnivores were instructed to either passively look at the pictures (Watch) or to change the appetitive value of the food (Increase or Decrease). In vegetarians, meat and fish dishes elicited lower desire to eat, pleasantness, and arousal during each condition as compared to both omnivores and vegetarian food. In contrast with the subjective data, no group differences were observed in any of the ERP measures, suggesting that similar neural processing of food-cues occurred in vegetarians and omnivores both during passive viewing and cognitive reappraisal. Concerning the late ERP effects during cognitive reappraisal, we found an enhancement of the P300 and LPP amplitudes during the Increase and the Decrease as compared to the Watch condition and a reduction of the SW amplitude in the Decrease as compared to Watch condition. These results suggest that in a food deprivation condition it is difficult to reduce the appetitive value of food stimuli, as this cognitive strategy appears to require greater effort and a longer time to be implemented with respect to up-regulation. Overall, our findings suggest that, in vegetarians, aversion towards nonvegetarian food prevails at the subjective level and is consistent with their personal beliefs. In contrast, at the neural level, the intrinsic motivational salience of this type of food is preserved.

RESUMO

INTRODUCTION: India ranks first among nations with the largest population of vegetarians, and 40% of Asian Indians are vegetarian. There seems to occur a "nutrition transition" among vegetarians in India with a decline in the consumption of whole plant food content and replacement with processed foods, fried foods, and refined carbohydrates. This study evaluates the association between the consumption of a vegetarian diet and the prevalence of morbid obesity necessitating bariatric surgery in Asian Indians. MATERIAL AND METHODS: This is a retrospective cohort study analyzing records of 235 Indian patients suffering from morbid obesity and who underwent bariatric surgery at our center through the years 2015 to 2017. Pearson's chi-square test for independence of attributes was applied to analyze the difference between a number of vegetarians versus non-vegetarians undergoing bariatric surgery. RESULTS: The difference in the number of vegetarians versus non-vegetarians undergoing bariatric surgery was not significant for years 2015 and 2017, but the number was numerically higher for vegetarians. The difference was significantly higher for vegetarians in the year 2016. The difference in female vegetarians versus female non-vegetarians undergoing bariatric surgery was not significant for the year 2017 but was significantly higher for vegetarians during the years 2015 and 2016. The difference in male vegetarians versus non-vegetarians undergoing bariatric surgery was not significant for all the years. CONCLUSION: In an Asian Indian cohort, we found that vegetarian dietary patterns were associated with a higher incidence of morbid obesity culminating in bariatric surgery. Our study is a myth breaker that all vegetarian diets are healthy diets. Our findings can be utilized to discourage refined and processed food consumption and promote healthy vegetarian food choices.
