RESUMO

BACKGROUND: Today, raw vegetarianism is considered one of the most important socio-cultural developments in contemporary societies. In this regard, the present study was conducted to describe the perceived experience of people adhering to a vegan diet through a phenomenological perspective. METHODS: This qualitative study explores the perceived experiences of individuals who follow a vegan diet and are part of the self-care campaign in Kermanshah, Iran. sampling was purposeful and face-to-face interviews were conducted with 12 individuals who follow a vegan lifestyle. The data were analyzed after being collected using the seven steps of Collizi. MAXQUDA software (version 12) was used for data management. RESULTS: After qualitative data analysis, we identified 567 codes, which were categorized into 15 sub-themes. From these sub-themes, we derived 4 main themes. The main themes include: In pursuit of redemption (Meaningful framework, In awareness path, Unequaled Disappointment, Chronic and complex conditions), Seeking the New World (Starting with doubt and hesitation, The temptation to return, Constant criticism, Unfamiliar appearance), On the path of overcoming difficulties (Associate problems, Matching the new way, Perceived recommendations), and attaining the expected outcomes (Healthy lifestyle, Therapeutic feedback, Enhancing emotional wellbeing, Feeling of youth). CONCLUSION: Based on the participants' experience, despite the challenging journey, the people with a vegetarian diet experienced partial and complete improvement of all the symptoms of the diseases. They had a healthy lifestyle and felt young and energetic. Likewise, this method had a positive effect on people's mental state and mood.

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

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.

RESUMO

This article is concerned with the dynamics of change in protein consumption practices from the perspective of the consumer. It is based on a model, informed by social representation theory, that aims to understand the role played by various types of representation of alternative proteins in the process of changing food consumption practices. It discusses the reception, by consumers, of the representations associated with alternative proteins on Instagram. Methodologically, three focus groups were organized with different consumer segments (omnivorous, flexitarian and vegetarian and vegan consumers), as well as seven individual interviews. Participants were submitted to the social representations of alternative proteins, and visual stimuli from social media were mobilized for this purpose. Results show that the publications which boast the environmental, animal welfare or health attributes of alternative proteins generally contribute to the cultivation of new elements of practices. While this kind of publications is essential to help consumers question their established practices linked to meat and dairy consumption, they can also generate a critical reception that is not conducive to change, making them a double-edge sword. Publications that relate to the representations involved in daily food consumption proteins (e.g. that alternative proteins are versatile and crowd-pleasing) emerge as being safer in terms of reception, although as standalone they may not be able to achieve a deep level of change in food consumption practices. The results of this study show the importance of deploying a diverse communication strategy about alternative proteins that appeal to a variety of consumer segments.

RESUMO

While moral concern for animals has become increasingly important for both consumer food choice and food policy makers, previous research demonstrated that meat eaters attribute lower moral status and mental capacities to animals raised for meat compared to non-food animals. The current research investigated whether this strategic flexibility in moral concern and mind perceptions also occurs when considering aquatic food animals and animals used for dairy and egg products, and the degree to which these concerns and perceptions are evident in pescatarians and vegetarians. We compared perceptions (mind attributions and moral concern) of land food animals versus aquatic food animals, and of animals in the meat versus dairy and egg industry between omnivores (n = 122), pescatarians (n = 118), vegetarians (n = 138), vegans (n = 120), and flexitarians (n = 60). Pescatarians scored lower than other dietary groups on moral concern and mind attribution for aquatic animals relative to farmed land animals. Unlike the other dietary groups, pescatarians and vegetarians scored lower on moral concern and mind attribution for dairy than beef cows and for layer chickens than broiler chickens. These findings demonstrate that pescatarians and vegetarians were flexible in their moral thinking about different types of food animals in ways that suited their consumption habits, even when the same animal was evaluated (e.g., dairy vs beef cows). This research highlights the psychological barriers that might prevent people from reducing animal product consumption and may need to be addressed in interventions to encourage transitioning towards more plant-based diets.

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

We conceptualize the journey to ethical veganism in the stages of the transtheoretical model of change, from precontemplation through contemplation, preparation, action, and maintenance. At each stage, we explore the psychological barriers to progressing towards veganism, discuss how they manifest, and explore ways to overcome them. It is hoped that this paper can be used as a guide for animal advocates to identify the stage an individual is at, and understand and overcome the social and psychological barriers they may face to progressing. We argue that, while many people are ignorant of the cruel practices entailed in animal farming, many deliberately avoid thinking about the issue, are unable to appreciate the scale of the issue, and simply tend to favour the status quo. When engaging with the issue of farm animal suffering, meat-eaters are largely driven by cognitive dissonance, which manifests as motivated reasoning aimed at protecting one's image of oneself and one's society. This is facilitated by confirmation bias and complicit media which cater to the preferred views of their meat-eating audience. Even once convinced of veganism, habit and willpower present further barriers to acting on those beliefs. This is all in the context of a speciesist and carnistic culture where meat consumption is normal, farming is noble, and vegans are 'others'. We locate and elucidate each of these biases within the stages of the transtheoretical model and discuss the implications of this model for animal advocates and for further research.

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

PURPOSE: This study aimed to analyze the association between the importance of several reasons to follow a vegan diet and the degree of orthorexic eating behavior in a sample of vegan individuals (N = 65, 53.8% women, age: M = 28.22 (SD = 9.13) years, BMI: M = 22.91 (SD = 3.44) kg/m2). RESULTS: The results reveal that orthorexic eating behavior is associated with the importance of the underlying motives health, esthetics and healing, whereas animal welfare, politics and ecology are not linked to orthorexia. CONCLUSION: Hence, this study reveals that a vegan lifestyle is not per se associated with orthorexic eating behavior, but rather that it varies with the underlying motivation for following a vegan diet.

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

One's relationship to food is an important factor that can contribute to wellbeing but can also lead to eating disturbances. Research in this area has linked vegetarianism and veganism to disordered eating. However, through social media, many young women have recently started to share their vegan experiences with many highlighting the role that veganism may have on promoting a 'healthier' psychosocial relationship to food. The current study aims to qualitatively explore the role that veganism plays in young women's wellbeing and relationship to food. Participants were ten young vegan women aged 18 to 25. Semi-structured interviews were analysed using Interpretative Phenomenological Analysis (IPA). These women were found to passionately engage in a vegan lifestyle, as opposed to just a vegan diet, which appeared to have a number of positive effects such as a healthier lifestyle, a stronger sense of control and agency, more meaningful social relationships, and a sense of connection to a vegan sub-culture. Through veganism, many of the women transitioned from social disconnection and a focus on body image, to a stronger emotional (empathic), cognitive (knowledge of animal cruelty and healthy eating), and behavioural (diet and consumption choices, connections with others) investment in their social worlds. We suggest that the healing potential of veganism, is derived from this passionate investment of the self that redefines young women's ways of being in the world. The healing benefits of engaging in a vegan lifestyle may have clinical significance for working with young women who are socially disengaged or who are at risk of disordered eating.

RESUMO

Orthorexia nervosa (ON) is a proposed diagnostic category that captures a pathological need to eat healthfully. The ORTO-15 is a self-report measure ostensibly designed to assess ON, but its suitability for capturing symptoms of pathology has been questioned. Vegans differ from omnivores in their focus on health and present with similar or lowered endorsement of eating behaviors symptoms, making them an ideal group to assess the construct validity of the ORTO-15. We tested the hypothesis that the ORTO-15 captures normative, rather than pathological, health focus. In total, 106 omnivores, 34 meat reducers, 50 lacto-ovo-vegetarians, and 191 vegans completed the ORTO-15 to quantify the presence and severity of ON and the Eating Disorder Examination Questionnaire (EDE-Q) as an established measure of eating pathology. More than 75% of respondents met criteria for a diagnosis of ON per established ORTO-15 cutoffs. Respondents above the 2.50 EDEQ cutoff (suggesting the likely presence of an eating disorder) did not differ in ORTO-15 scores from those scoring below the cutoff. There was a univariate main effect of meat avoidance type on the EDE-Q global scale (p < .01), with vegans endorsing fewer symptoms on the EDE-Q than semi-vegetarians (post-hoc p < .05). Vegans were more likely to meet the clinical ON cutoff of 40 on the ORTO-15 compared to omnivores (omnibus p < .01; post-hoc p = .01). Based on the ORTO-15, vegans' scores should be indicative of pathological eating behavior, but EDE-Q scores instead indicate the lowest levels in this group. The ORTO-15 is able to differentiate between types of meat avoiders, but given the difference in health focus between groups, the scale may be tapping into a construct other than pathological eating beliefs and behaviors.

RESUMO

PURPOSE: Although research on vegetarianism is becoming more prevalent, to date, only a few research has been conducted on relationship between vegetarian diet and orthorexia nervosa (ON). The objective of the present study was to examine the orthorexic dietary patterns and eating behaviours among individuals following a vegetarian, vegan, and meat diet. We examined the moderating role of ethical and health reasons for following a meat-free diet on the relation between vegan versus vegetarian diet and eating behaviours and ON. The study aimed to determine the predictors of ON in individuals with differential food preferences. METHODS: Seventy-nine individuals following a meat-free diet and 41 individuals following an omnivore diet completed the EHQ and the TFEQ-R18. RESULTS: Our findings indicated that individuals following a vegan diet showed a higher level of knowledge of healthy eating than those who followed a vegetarian diet and those who followed an omnivore diet. Participants maintaining a vegan diet for health reasons were more likely to have greater knowledge about healthy eating. Cognitive restraint was a predictor of ON among a sample following a meat-free diet. CONCLUSIONS: Our results could contribute to identify potential risk factors for strict health-oriented eating patterns and to gain a better insight into ON. LEVEL OF EVIDENCE: Level V, descriptive study.

RESUMO

OBJECTIVE: The Eating Disorder Examination-Questionnaire (EDE-Q) is a valid and reliable measure of eating-related pathology, but its factor structure has proven difficult to replicate. Given differences in dietary patterns in vegans compared to omnivores, proper measurement of eating disorder symptoms is especially important in studies of animal product avoiders. METHOD: This study compared goodness-of-fit of five alternative models of the EDE-Q in vegans (i.e., individuals refraining from all animal products, n = 318) and omnivores (i.e., individuals not restricting intake of animal products, n = 200). Confirmatory factor analyses were used to compare fit indices of the original four-factor model of the EDE-Q, along with alternative three-, two-, full one-, and brief one-factor models. RESULTS: No model provided adequate fit of the data in either sample of respondents. The fit of the brief one-factor model was the closest to acceptable in omnivores, but did not perform as well in vegans. Indicators of fit were comparable in vegans and omnivores across all other models. DISCUSSION: Our data confirm difficulties in replicating the proposed factor structure of the EDE-Q, including in vegans. More research is needed to determine the suitability of the EDE-Q for quantifying eating behaviors, including in those abstaining from animal products.

RESUMO

Although there are many studies of determinants of vegetarianism and veganism, there have been no previous studies of how their rates in a population jointly change over time. In this paper, we present a flexible model of vegetarian and vegan dietary choices, and derive the joint dynamics of rates of consumption. We fit our model to a pseudo-panel with 23 years of U.K. household data, and find that while vegetarian rates are largely determined by current household characteristics, vegan rates are additionally influenced by their own lagged value. We solve for equilibrium rates of vegetarianism and veganism, show that rates of consumption return to their equilibrium levels following a temporary event which changes those rates, and estimate the effects of campaigns to promote non-meat diets. We find that a persistent vegetarian campaign has a significantly positive effect on the rate of vegan consumption, in answer to an active debate among vegan campaigners.

RESUMO

It is well established that the amount eaten by other people affects how much we eat, but unanswered questions exist regarding how much the food choices of other people affect the types of food that we choose. Past research on food choice modeling has primarily been conducted in controlled laboratory situations and has focused on snack foods. The current research examines the extent to which food choice modeling of a main dish occurs in a real-life context and whether people are aware of being influenced by others. The lunch orders of café patrons were surreptitiously tracked and participants were recruited after they paid for their lunch. Participants were asked what they ordered, whether they were influenced by the prior order, and what their relationship was to the person ahead of them in line. We analyzed the data of participants who were not acquainted with the person ahead of them (N = 174). As hypothesized, participants' main-dish lunch orders matched the choice of the person ordering ahead of them in line at rates significantly higher than chance. A significant modeling effect was observed even among participants who reported that their order was not influenced by the prior order. This research provided evidence of main-dish choice modeling occurring in real-life eating situations and outside of conscious awareness - demonstrating a powerful social influence on eating behaviours.

RESUMO

This descriptive study was performed to compare signs of orthorexia nervosa and eating habits and attitudes of vegans/vegetarians and nonvegans/nonvegetarians. The study sample included 62 people, of whom 31 were vegan/vegetarian and 31 were nonvegan/nonvegetarian. Data were gathered with a personal characteristics form, Orthorexia Nervosa Evaluation Scale-11, Eating Attitudes Test-40 and Maudsley Obsessive Compulsive Inventory. There were not any significant differences between scores for Orthorexia Nervosa Evaluation Scale-11, Eating Attitudes Test-40 and Maudsley Obsessive Compulsive Inventory (p>0,05). As scores for Orthorexia Nervosa Evaluation Scale-11 decreased, predisposition to orthorexia nervosa increased. Therefore, although correlation coefficients were negative, they were considered positive. There was a significant, negative relation between Eating Habits Test-40 scores and Orthorexia Nervosa Evaluation Scale-11 scores (r=-0.290, p=0.002) and between Maudsley Obsessive Compulsive Inventory scores and Orthorexia Nervosa Evaluation Scale-11 scores (r=-0.319, p=0.012). As poor eating habits and obsessive symptoms increased, so did orthorectic symptoms. In light of obtained results, it seems that people become vegan/vegetarian mainly for ethical reasons and that veganism/vegetarianism is not associated with obsession of healthy eating.

RESUMO

PURPOSE: Orthorexic eating behaviour, restrained eating, and veganism/vegetarianism are food selection strategies sharing several characteristics. Since there are no studies investigating their interrelationships, aim of the present study was to analyse orthorexic and restrained eating behaviour in (1) a sample of vegans and vegetarians and (2) a sample of individuals on a diet to lose weight. METHOD: Division of samples according to pre-defined criteria in (1) vegans (n = 114), vegetarians (n = 63), individuals with rare meat consumption (n = 83) and individuals with frequent meat consumption (n = 91) and in (2) participants on a diet with dietary change (n = 104), without dietary change (n = 37) and a control group of individuals not on a diet (n = 258). Orthorexic eating behaviour was assessed with the Düsseldorfer Orthorexie Skala and restrained eating was assessed with the Restraint Eating Scale. RESULTS: Vegans and vegetarians do not differ in orthorexic eating behaviour, but both groups score higher in orthorexic eating behaviour than individuals consuming red meat. There are no differences regarding restrained eating. Individuals on a diet with dietary change score higher in both orthorexic and restrained eating, than individuals without dietary change and individuals not on a diet. CONCLUSIONS: Individuals who restrict their eating behaviour, either predominantly due to ethical reasons or with the intention to lose weight, display more orthorexic eating behaviour than individuals not limiting their food consumption. Further research is needed to investigate whether veganism, vegetarianism, or frequent dieting behaviour serve as risk factors for orthorexia. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

RESUMO

Studies comparing eating behaviors in individuals avoiding meat and other animal products to omnivores have produced largely inconclusive findings, in part due to a failure to obtain sufficiently large samples of vegan participants to make meaningful comparisons. This study examined eating and health behaviors in a large community sample of dietary vegans ("vegans"), compared to omnivores. Participants (n = 578, 80.4% female) completed an online questionnaire assessing a range of eating- and other health-related attitudes and behaviors. Vegans (62.0%, n = 358) and omnivores (38.1%, n = 220) were comparable in terms of demographics. Vegans scored significantly lower than omnivores the Eating Disorder Examination - Questionnaire (multivariate p < 0.001), a measure of pathological eating behavior. They also were more likely to consider themselves "healthy" (p < 0.001) and to prepare food at home (p < 0.001). Vegans more frequently consumed fruits, vegetables, nuts, beans and grains (all p < 0.001), and less frequently consumed caffeinated soft drinks (p < 0.001). There were no significant differences between vegans and omnivores on measures of eating styles, body mass index, smoking or exercise behaviors, or problems related to alcohol consumption. Effect sizes for comparisons on eating-related measures were generally small, with ηp2 ranging from <0.01 to 0.05; the size of effects for comparisons on measures of other health behaviors ranged from small to medium (Φ = 0.09 to 0.33 and ηp2 < 0.01 to 0.42). Taken together, findings suggest that ultimately, vegans do not differ much from omnivores in their eating attitudes and behaviors, and when they do, differences indicate slightly healthier attitudes and behaviors towards food. Similarly, vegans closely resembled omnivores in non-eating related health behaviors.
