Abstract
Objective To examine health behavior and environmental perception differences among vegetarian and nonvegetarian students. Participants: First-year university students (n = 1078) from eight United States universities. Methods: Data were obtained from base 2015 and followup 2016 assessments. Vegetarians and nonvegetarians were compared for anthropometrics, lifestyle behaviors, and campus environmental perceptions (CEPS). Results: Vegetarians had smaller waist circumference, lower systolic blood pressure, higher fruit and vegetable consumption, lower percentage of energy obtained from fat, and higher perceived stress. Vegetarians expressed a lower rating of perceptions of health policies on campus. Conclusion: A clear difference in indicators of physical health does not appear, however, vegetarian students show positive dietary patterns which can promote positive health outcomes. Further, vegetarians had lower perceptions of health policies on campus. Results can be used by administrators to ensure policies are in place to support health of students as currently vegetarian students see limitations in the environmental health policies.

Abstract
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.

The multidimensional nature of food neophobia. Appetite 2021; 162:105177.

Abstract
People vary in their willingness to try new foods. This variation, which is most frequently measured using the Food Neophobia Scale (FNS; Pliner & Hobden, 1992), has been interpreted as unidimensional. In four studies (N's = 210, 306, 160, and 161), we 1) demonstrate that food neophobia varies across meat and plant dimensions, 2) explore the validity of a measure of meat and plant neophobia, and 3) test whether these food neophobia dimensions predict decisions to eat a novel food item (i.e., a snack bar that contains insects). Mixed-effects model across the four studies indicated that the two dimensions differentially relate to a number of variables, including disgust sensitivity, animal empathy, and masculinity. Women scored higher on meat neophobia than men, but the sexes did not differ on plant neophobia. Only meat neophobia uniquely predicted eating a novel insect-based snack bar. Overall, these results extend knowledge regarding orientations toward novel foods.

Abstract
OBJECTIVE Previous research has suggested a link between vegetarianism, broadly defined, and symptoms of eating disorders (ED). However, the literature supporting this link is mixed and limited by possible measurement artifacts. Using data from a national sample of college students, the present study examines ED symptomatology among three groups: (a) vegetarians whose meat avoidance is motivated by weight concerns; (b) non-weight motivated vegetarians; and (c) nonvegetarians. METHOD Participants include 9,910 students from 12 colleges and universities across the United States who participated in the web-based Healthy Bodies Study. ED symptomatology was measured using the Short-Eating Disorder Examination-Questionnaire (S-EDE-Q). First, multi-group confirmatory factor analysis was conducted to test measurement invariance (MI) of the S-EDE-Q across weight-motivated vegetarians, non-weight-motivated vegetarians, and nonvegetarians. Gender- and BMI-adjusted ANCOVA was used to compare S-EDE-Q scores across groups. RESULTS 9.3% of participants were vegetarian. Cis-women and gender minority students were more likely to be vegetarian; those who became vegetarians after entering college were more likely to report weight-related motivations. Strict MI was supported for the S-EDE-Q global and subscale scores. Weight-motivated vegetarians reported higher levels of restraint, shape/weight overvaluation, body dissatisfaction, and global ED psychopathology relative to other participants. DISCUSSION To our knowledge, this is the first to explicitly link weight motivations for vegetarianism to ED psychopathology in a large, representative sample of young adults. Results suggest that students presenting with ED symptoms should be assessed for their motivations for adopting a vegetarian diet, and this information should be considered in treatment decisions.

Abstract
Objective: To examine the relation between the consumption or avoidance of meat and psychological health and well-being.Methods: A systematic search of online databases (PubMed, PsycINFO, CINAHL Plus, Medline, and Cochrane Library) was conducted for primary research examining psychological health in meat-consumers and meat-abstainers. Inclusion criteria were the provision of a clear distinction between meat-consumers and meat-abstainers, and data on factors related to psychological health. Studies examining meat consumption as a continuous or multi-level variable were excluded. Summary data were compiled, and qualitative analyses of methodologic rigor were conducted. The main outcome was the disparity in the prevalence of depression, anxiety, and related conditions in meat-consumers versus meat-abstainers. Secondary outcomes included mood and self-harm behaviors.Results: Eighteen studies met the inclusion/exclusion criteria; representing 160,257 participants (85,843 females and 73,232 males) with 149,559 meat-consumers and 8584 meat-abstainers (11 to 96 years) from multiple geographic regions. Analysis of methodologic rigor revealed that the studies ranged from low to severe risk of bias with high to very low confidence in results. Eleven of the 18 studies demonstrated that meat-abstention was associated with poorer psychological health, four studies were equivocal, and three showed that meat-abstainers had better outcomes. The most rigorous studies demonstrated that the prevalence or risk of depression and/or anxiety were significantly greater in participants who avoided meat consumption.Conclusion: Studies examining the relation between the consumption or avoidance of meat and psychological health varied substantially in methodologic rigor, validity of interpretation, and confidence in results. The majority of studies, and especially the higher quality studies, showed that those who avoided meat consumption had significantly higher rates or risk of depression, anxiety, and/or self-harm behaviors. There was mixed evidence for temporal relations, but study designs and a lack of rigor precluded inferences of causal relations. Our study does not support meat avoidance as a strategy to benefit psychological health.

Abstract
Individuals with disordered eating commonly exclude salt and animal products from their diets, which may predispose them to iodine deficiency even without significant weight loss. Overconsumption of dietary supplements and "natural" foods are also commonly observed among eating disorder patients. This report describes an adolescent female with disordered eating presenting with growth and pubertal delay, found to have severe iodine deficiency (urine iodine of 18 mcg/L) and abnormal thyroid function resulting from strict avoidance of salt and animal products despite adequate caloric intake. To avoid having to start eating animal products, she began consuming excessive quantities of seaweed supplements to increase her iodine intake resulting in excessive iodine levels (urine iodine of >1,500 mcg/L) and worsening of thyroid function. When her parents began supervising her nutritional intake, her abnormal iodine levels, abnormal thyroid function tests, and hypogonadotropic hypogonadism all resolved. This is the first report of both iodine deficiency and iodine excess developing from disordered eating behavior.

Abstract
A carefully planned vegetarian diet meets nutrition recommendations by providing essential nutrients and lowering levels of saturated fat and cholesterol. Because balanced diets that limit or exclude meat tend to be lower in calories than omnivorous diets, it has been suggested that vegetarian eating patterns may be motivated by weight control. This view has been supported by findings demonstrating that vegetarians have a higher rate of disordered and restrained eating than non-vegetarians. Other findings suggest that weight control is a primary reason identified by adolescents and young adults for eliminating items such as meat and other animal products from their diet. Thus, it has been suggested that vegetarianism may provide a socially acceptable means to control body weight. However, this may be an over-generalization. Vegetarians are a heterogeneous group of individuals with radically different eating habits. Moreover, they are often compared to omnivores who eat meat on a regular basis. These omnivorous eating habits do not represent a growing subset of the population, many of whom are adopting a flexitarian diet that involves only the occasional consumption of meat. The goal of the current paper will be to demonstrate that semi-vegetarians and flexitarians are categorically different from vegans, lacto-ovo-vegetarians, and omnivores and describe the motivations as well as the positive and negative health implications that are associated with dietary patterns that limit the intake of meat. It is important for us to understand the motivations and behaviors that are characteristic of flexitarians in order to develop effective evidence-based strategies to address unhealthy eating behaviors.

Abstract
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.

Abstract
BACKGROUND Vegetarian nutrition is gaining increasing public attention worldwide. While some studies have examined differences in motivations and personality traits between vegetarians and omnivores, only few studies have considered differences in motivations and personality traits between the 2 largest vegetarian subgroups: lacto-ovo-vegetarians and vegans. OBJECTIVES To examine differences between lacto-ovo-vegetarians and vegans in the distribution patterns of motives, values, empathy, and personality profiles. METHODS An anonymous online survey was performed in January 2014. Group differences between vegetarians and vegans in their initial motives for the choice of nutritional approaches, health-related quality of life (World Health Organization Quality of Life-BREF (WHOQOL-BREF)), personality traits (Big Five Inventory-SOEP (BFI-S)), values (Portraits Value Questionnaire (PVQ)), and empathy (Empathizing Scale) were analyzed by univariate analyses of covariance; P values were adjusted for multiple testing. RESULTS 10,184 individuals completed the survey; 4,427 (43.5%) were vegetarians and 4,822 (47.3%) were vegans. Regarding the initial motives for the choice of nutritional approaches, vegans rated food taste, love of animals, and global/humanitarian reasons as more important, and the influence of their social environment as less important than did vegetarians. Compared to vegetarians, vegans had higher values on physical, psychological, and social quality of life on the WHOQOL-BREF, and scored lower on neuroticism and higher on openness on the BFI-S. In the PVQ, vegans scored lower than vegetarians on power/might, achievement, safety, conformity, and tradition and higher on self-determination and universalism. Vegans had higher empathy than vegetarians (all p < 0.001). DISCUSSION This survey suggests that vegans have more open and compatible personality traits, are more universalistic, empathic, and ethically oriented, and have a slightly higher quality of life when compared to vegetarians. Given the small absolute size of these differences, further research is needed to evaluate whether these group differences are relevant in everyday life and can be confirmed in other populations.

Abstract
Background The present study investigated associations between vegetarian diet and mental disorders. Methods Participants were drawn from the representative sample of the German Health Interview and Examination Survey and its Mental Health Supplement (GHS-MHS). Completely vegetarian (N = 54) and predominantly vegetarian (N = 190) participants were compared with non-vegetarian participants (N = 3872) and with a non-vegetarian socio-demographically matched subsample (N = 242). Results Vegetarians displayed elevated prevalence rates for depressive disorders, anxiety disorders and somatoform disorders. Due to the matching procedure, the findings cannot be explained by socio-demographic characteristics of vegetarians (e.g. higher rates of females, predominant residency in urban areas, high proportion of singles). The analysis of the respective ages at adoption of a vegetarian diet and onset of a mental disorder showed that the adoption of the vegetarian diet tends to follow the onset of mental disorders. Conclusions In Western cultures vegetarian diet is associated with an elevated risk of mental disorders. However, there was no evidence for a causal role of vegetarian diet in the etiology of mental disorders.

Abstract
There is considerable variation in reference values for micronutrient intake during lactation across Europe. The European Micronutrients Recommendations Aligned project aims to harmonize dietary recommendations throughout Europe. Recommended nutrient intakes during lactation are based on limited data and are often extrapolated from known secretion of the nutrient in milk with adjustments for bioavailability, so that differences between values can be partly ascribed to differences in methodological approaches and how these approaches were applied. Few studies have considered the impact of lactation on the mother's nutritional status. Rather, focus has been placed on the influence of maternal nutritional status on the composition of her breast milk. Most common nutritional deficits in breast milk are the result of maternal deficiencies of the water-soluble vitamins, thiamine, riboflavin and vitamins B6 and B12. Other than maternal vitamin A status, which to some extent is reflected in breast milk, concentrations of fat-soluble vitamins and most minerals in breast milk are less affected by maternal status. Factors relating to suboptimal maternal nutritional status during lactation include maternal age, diet and lifestyle factors and spacing of consecutive births. Recent research is providing new knowledge on the micronutrient requirements of lactating women. Identifying needs for research and improving understanding of the differences in values that have been derived by various committees and groups across Europe will enhance transparency and facilitate the application of dietary recommendations in policy-making decision and their translation into recommendations for lactating women. Given the wide variation in breastfeeding practices across Europe, making nutritional recommendations for lactating women is complex and challenging. Thus, it is crucial to first examine the cultural practices within and across European populations and to assess its relevance before making recommendations.

Abstract
This article proposes a new bio-psychosocial perspective on the links between mental health, more specifically suicide, and nutrition. We first discuss the links between nutrition, its social role and suicide. The act of eating is studied as a social integrator and regulator, in the light of Durkheim's theorization. Nutrition is also examined as self-destruction, with particular cases of "diet-related suicide." De-structuring of meals and alienating foods are identified as contributing factors to the de-structuring of "nutrition models." We then discuss the place of food within the psychopathology, and finally, the links between biological parameters reflected in food and suicide risk. Avenues of research and intervention along this bio-psychosocial approach are also proposed.

An International Comparison of Female and Male Students' Attitudes to the Use of Animals. Animals (Basel) 2010; 1:7-26. [PMID: 26486211 PMCID: PMC4552214 DOI: 10.3390/ani1010007] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2010] [Accepted: 12/08/2010] [Indexed: 12/04/2022] Open
Abstract
Previous research has demonstrated that in households where the male partner is more dominant, there is convergence in male and female attitudes towards animals, whereas if the female partner is empowered they exhibit greater empathy towards animals than the male partner. We tested this theory of 'female empowered empathy' internationally in a survey of female and male students' attitudes towards use of animals, conducted in 11 Eurasian countries: China, Czech Republic, Great Britain, Iran, Ireland, South Korea, Macedonia, Norway, Serbia, Spain and Sweden. Gender empowerment was estimated for each country using the Gender Empowerment Measure designed by the United Nations. The survey was administered via the internet in universities within countries, and 1,902 female and 1,530 male student responses from 102 universities were received. Respondents rated the acceptability of 43 major concerns about human use of animals, and the importance of 13 world social issues, including animal protection, environmental protection and sustainable development. Females had greater concern for animal welfare and rights than males. There was a positive correlation between the Gender Empowerment Measure and the ratio of female to male concern for animal welfare and rights, but not for other world issues. Thus in countries where females were more empowered, principally Sweden, Norway and Great Britain, females had much greater concern than males for animal issues, whereas in other countries the responses of males and females were more similar. Across countries female students were more likely to avoid meat and less likely to avoid eggs, milk and seafood than male students, and were more likely to have kept pets than males. Females rated cats as more sentient than males did. The results demonstrate that females have greater concern for animal welfare and rights than males, and that this is more likely to be expressed in countries where females are relatively empowered, suggesting that 'emancipated female empathy' operates across countries as well as at a local level.

Legume consumption and severe depressed mood, the modifying roles of gender and menopausal status. Public Health Nutr 2010; 13:1198-206.

Abstract
OBJECTIVE Legumes have been recommended as staple foods in the anticipation of disease prevention. However, the scientific evidence of their benefits, particularly on mental well-being, remains preliminary. We longitudinally assessed the association between legume consumption and the risk of severe depressed mood (SDM) among a national cohort. DESIGN The study included adults aged 25-74 years who were examined in 1971-1975 as a part of the National Health and Nutrition Examination Survey. Legume consumption at baseline was obtained from a 3-month FFQ and categorised as infrequent (<1 time/week), moderate (1-2 times/week) and frequent (> or = 3 times/week). SDM was defined as Center for Epidemiologic Studies Depression Scale score > or = 22 or taking anti-depression medication after an average of 10.6 years of follow-up (from 8.0 to 12.5 years). RESULTS Among women, the proportion of individuals with SDM was 17.75 %. For premenopausal women (n 1778), a significant linear trend of deleterious effect from legume consumption was observed (P for trend = 0.0148). The relative risks (RR) for infrequent, moderate and frequent consumptions were 1 (reference), 1.24 (95 % CI = 0.91, 1.70) and 1.75 (1.12, 2.75), respectively. However, moderate consumption showed a significant protective effect (RR = 0.52 (0.27, 1.00)) among women undergoing the menopausal transition (n 454). No association was obtained from either postmenopausal women (n 601) or men (n 2036). CONCLUSIONS These findings suggest that gender and menopausal status were effect modifiers of the association between legume consumption and SDM. Detrimental effects of frequent consumption of legumes may exist among premenopausal women; moderate consumption, however, may protect perimenopausal women against SDM.

Abstract
Increased evidence indicates an association between psychiatric disorders and dietary pattern. The objective of this study is to describe the differences in food consumption between suicide attempters and non-attempters. We analyzed the dietary information retrospectively collected from 6803 adults, aged 17 to 39 years, who also completed a mental disorder diagnostic interview as a part of the Third National Health and Nutrition Examination Survey, 1988-1994. The Healthy Eating Index score was used to measure the degree of compliance with the national diet guidelines. In men, attempters (n=92) had a high odds of low consumption of vegetables (OR=2.47, 95%CI=1.19, 5.15). In women, attempters (n=275) had a high odds of insufficient fruit consumption (OR=2.36, 95%CI=1.15, 4.85). For both men and women, the component scores for meat were lower in non-attempters compared with attempters. On a scale of zero (no serving) to 10 (meeting the serving recommendations), the scores were 6.74 (SE: 0.39) and 7.76 (0.10), respectively, for attempters and non-attempters among men, and 5.81 (0.33) and 6.43 (0.07), respectively, for attempters and non-attempters among women. It was further observed that female attempters ate significantly less fish and seafood. These results were obtained after adjustment for various factors, including the history of medical and psychiatric illnesses. The data suggest that fruits, vegetables and meat were significantly under-consumed in adults who had ever attempted suicide. The deleterious contribution of insufficient consumption of these foods to physical and psychiatric status in attempters merits investigation. In clinical practice, psychiatrists should pay more attention to what patients eat.

Abstract
AIMS Sociocultural factors are thought to be important in the pathogenesis of eating disorders. However, there have been few studies comparing eating behavior among various cultural populations. The aim of the present study is to compare attitudes towards bodyweight and shape, and desire for thinness in Japanese male and female subjects with those in people from other countries and of different ethnic origin. METHODS The subjects were 411 Japanese, 130 Indian, 135 Omani, 113 Euro-American and 196 Filipino adolescents. The Eating Attitude Test-26 and the Drive for Thinness subscale of the Eating Disorder Inventory-2 were used to assess eating attitudes and fat phobia. RESULTS Subjects from India, Oman and the Philippines demonstrated eating attitudes that were similar to or worse than subjects from Western countries and Japan, although their desire for thinness was not as strong. The relationship between body mass index and eating attitudes or fat phobia in Indian, Omani and Filipino subjects differed from that in subjects from Western countries and Japan. In addition, both males and females showed disturbed eating attitudes in the Indian, Omani, and Filipino subjects. CONCLUSION There are differences in eating attitudes and the drive for thinness among different cultural groups.

Abstract
This study aimed to identify attitudes, health behaviours, social adjustment and self-reported health of vegetarian and omnivore teenagers and determine characteristics independently related to vegetarian status. Participants were 630 Grade 9 students, ages 13-15 years, in seven schools in Ontario, Canada. Vegetarian status was determined using a 19-item food inventory. The vegetarian group included lacto, ovo and/or lacto-ovo and semi-vegetarians. Omnivores consumed red meat at least monthly. Social adjustment factors included school misbehaviour, low academic performance, authority-defying risks and unsafe/illegal risks. Logistic regression estimated the relationship of characteristics to vegetarian status. The sample comprised 25 vegetarians (4%) and 605 omnivores. Analyses focussed mainly on females; 22 vegetarians and 315 omnivores. Dieting behaviours (current, frequent and past year), alcohol use, poorer social adjustment and poorer self-rated health were positively related to vegetarian eating (p<.05). Among females (using logistic regression), past year dieting (OR 9.88; 95% CI 2.19-44.47) and alcohol use (OR 2.91; 95% CI 1.02-8.32) predominated in the presence of attitudes that personal health and animal rights are very important. The model predicted 79.9% of cases. Teenage vegetarians were distinctive in health behaviours. The independent, positive association of alcohol use with vegetarian eating is a unique and concerning finding. Dieting behaviours were strongly, independently and positively linked to female vegetarian eating. Further studies with a greater range of behaviours would be useful to more fully characterize teenage vegetarians and explore subgroups.

Abstract
AbstractObjectiveTo compare the sociodemographic characteristics, health status and health service use of vegetarians, semi-vegetarians and non-vegetarians.DesignIn cross-sectional data analyses of the Australian Longitudinal Study on Women's Health in 2000, 9113 women (aged 22–27 years) were defined as non-vegetarians if they reported including red meat in their diet, as semi-vegetarians if they excluded red meat and as vegetarians if they excluded meat, poultry and fish from their diet.ResultsThe estimated prevalence was 3% and 10% for vegetarian and semi-vegetarian young women. Compared with non-vegetarians, vegetarians and semi-vegetarians were more likely to live in urban areas and to not be married. Vegetarians and semi-vegetarians had lower body mass index (mean (95% confidence interval): 22.2 (21.7–22.7) and 23.0 (22.7–23.3) kg m− 2) than non-vegetarians (23.7 (23.6–23.8) kg m− 2) and tended to exercise more. Semi-vegetarians and vegetarians had poorer mental health, with 21–22% reporting depression compared with 15% of non-vegetarians (P < 0.001). Low iron levels and menstrual symptoms were also more common in both vegetarian groups. Vegetarian and semi-vegetarian women were more likely to consult alternative health practitioners and semi-vegetarians reported taking more prescription and non-prescription medications. Compared with non-vegetarians, semi-vegetarians were less likely and vegetarians much less likely to be taking the oral contraceptive pill.ConclusionThe levels of physical activity and body mass indices of the vegetarian and semi-vegetarian women suggest they are healthier than non-vegetarians. However, the greater reports of menstrual problems and the poorer mental health of these young women may be of clinical significance.

Abstract
The purpose of this study was to replicate and expand upon previous research that has examined the potential association between vegetarianism and disordered eating. Limitations of previous research studies are addressed, including possible low reliability of measures of eating pathology within vegetarian samples, use of only a few dietary restraint measures, and a paucity of research examining potential differences in body image and food choice motives of vegetarians versus nonvegetarians. Two hundred and fifty-six college students completed a number of measures of eating pathology and body image, and a food choice motives questionnaire. Interestingly, no significant differences were found between vegetarians and nonvegetarians in measures of eating pathology or body image. However, significant differences in food choice motives were found. Implications for both researchers and clinicians are discussed.

Abstract
OBJECTIVE Research examining the relationship between dietary restraint and vegetarianism has yielded inconsistent results due to differing definitions of vegetarianism and the possible modifying role of feminist identity. The current study sought to further clarify these relationships by examining three levels of vegetarianism, motivation for vegetarianism, and feminist identity (using an updated measure). METHOD Participants were 90 female undergraduate students and community members (mean age=24.34 years). Dietary restraint was measured using the TFEQ; feminism was assessed using the LFAIS. RESULTS Weight-motivated semi-vegetarians reported higher levels of dietary restraint than those not motivated by weight. This effect did not appear among full-vegetarians. Lowest levels of dietary restraint were found among full-vegetarians with no difference between non- and semi-vegetarians. Contrary to previous research, feminist identity did not moderate the relationship between dietary restraint and vegetarianism. DISCUSSION Limitations resulting from a scale with a narrow definition of feminism and the use of multiple sources of recruitment are discussed. Directions for future research are highlighted.

Abstract
During the past decade, vegetarianism has risen in popularity among American families. Well-planned vegetarian diets can satisfy the nutritional needs and promote normal growth of infants and children. Research has highlighted nutritional advantages to vegetarian diets and has indicated that this style of eating can lead to lifelong healthy eating habits when adopted at a young age. Several vitamins, minerals, and macronutrients may be deficient within a vegetarian diet. Careful nutrition assessment and counseling will allow nurse practitioners to play a key role in encouraging families to adopt healthy eating habits to assist in disease prevention.

Abstract
STUDY OBJECTIVE Using four cases, this study describes common etiological factors and clinical sequelae in anorexia nervosa and athletic anorexia to present a biological explanation for interactions. DESIGN Four anorectic girls were interviewed regarding their training programs and dietary intake. Bone mineral content, hormonal status, and energy intake were assessed during follow-ups. RESULTS All the girls began training before puberty and had a low energy intake for age and height. Amenorrhea, low bone mineral content with stress fractures in three cases, and growth retardation in one case, were present at the follow-up after 6 years. Low amount of body fat and high serum cortisol is indicated and included in the discussion. The etiology is presented in an integrated model in addition to a biological explanation based on a negative energy balance, an acidic condition. CONCLUSION Energy deficits during puberty can result in the clinical sequela of the anorexia syndrome.

Abstract
The aim of this study was to identify sources of nutrients in diets of young Swedish vegans and omnivores. Three months of dietary intakes were investigated by diet history interviews. Volunteers were recruited through advertising and visits to schools in the city of Umeå, Sweden. Thirty vegans, 15 female and 15 male, aged 17.5+/-1.0 years, were compared with 30 sex-, age-, and height-matched omnivores. Vegans had different sources of nutrients than young omnivores and relied to a great extent on dietary supplements as a source of vitamin B-12, vitamin D, calcium, and selenium. Dietary intake of vegetables, fruits, and berries exceeded 500 g/day for 21 of the 30 vegans, whereas the same held true for only 1 of the 30 omnivores. Instead of animal products, young vegans rely on dietary supplements, legumes, vegetables, fruits, and berries as sources of nutrients.

Abstract
The purpose of this study was to determine whether differences exist in eating attitudes, self-esteem, social trait anxiety and social physique anxiety of self-reported vegetarian and nonvegetarian Turkish adolescents. The sample for the Turkish University' students is designed to provide the estimates of vegetarian indicators and prevalence. The participants were 608 females and 597 males, in total 1205 adolescents aged between 17 and 21 years. Disturbed eating behaviors (EAT-26> or =20) was found in 45.2% (14 of vegetarian) of the total vegetarian sample; which included two of the male vegetarians and 12 of the female vegetarians. The mean BMI was 19.78+/-1.49 kg/m(2) for female vegetarians and 20.78+/-2.46 kg/m(2) for female nonvegetarians (p<0.05). Male vegetarians had significantly higher score than male nonvegetarians on EAT-26 (17.25+/-11.18 for male vegetarians and 9.38+/-6.60 for male nonvegetarians), dieting (6.50+/-7.65 for male vegetarians and 2.55+/-3.87 for male nonvegetarians) and oral control (6.13+/-4.67 for male vegetarians and 3.20+/-3.19 for male nonvegetarians) scores (p<0.05). Besides, female vegetarians had significantly higher score than female nonvegetarians on EAT-26 (22.04+/-13.62 for female vegetarians and 11.38+/-8.28 for female nonvegetarians), dieting (10.35+/-9.58 for female vegetarians and 4.41+/-5.30 for female nonvegetarians), oral control (7.78+/-5.13 for female vegetarians and 3.33+/-3.51 for female nonvegetarians) and STAI (51.39+/-7.28 for female vegetarians and 47.29+/-5.13 for female nonvegetarians) scores (p<0.05). As a conclusion, the present study indicated abnormal eating attitudes, low self-esteem, high social physique anxiety, and high trait anxiety in Turkish vegetarian adolescents. The vegetarian adolescents may be more likely to display disordered eating attitudes and behaviors than nonvegetarians.

Abstract
BACKGROUND This study aimed to describe the dietary intakes of adolescent vegetarians and omnivores and determine if, and how, attitude toward personal health related to food consumption. METHODS Among grade 9 students in Ontario, Canada (n = 630), vegetarian status and estimated consumption of foods and food groups were determined by food frequency questionnaire. Personal health was self-categorized as very important (the "health conscious") or somewhat/not important (the "non-health conscious"). RESULTS The prevalence of vegetarianism was 6.5% (CI = 4.6-8.4%) among females and 1.0% (CI = 0.2-1.8%) among males. Health-conscious omnivores consumed more grain, vegetables and fruit, and milk product than non-health-conscious omnivores (P < 0.05). Health-conscious vegetarians ingested more grain products, vegetables and fruit, and meat and alternatives than non-health-conscious vegetarians (P < 0.05). Among non-health-conscious vegetarians, none consumed two daily servings of meat and alternatives compared to 60.5% of non-health-conscious omnivores (P < 0.001). Among health-conscious vegetarians, milk product consumption was lower than that of health-conscious omnivores (P = 0.015). CONCLUSIONS Large proportions of both vegetarian and omnivore adolescents consumed suboptimal diets. Health consciousness had value as an indicator of dietary adequacy and may be useful as a rudimentary screen for problematic dietary consumption patterns.

Abstract
There has been little research examining the link between dietary fat intake and the symptoms and consequences of anorexia nervosa. In this selective literature review, the potential significance of poly-unsaturated fatty acids is discussed. It is hypothesised that dietary restriction causes essential fatty acid deficiencies and poly-unsaturated fatty acid abnormalities, which might contribute to the physical and mental symptoms and the maintenance of the disorder. The examination of epidemiology, symptoms, co-morbidity, and consequences suggest that poly-unsaturated fatty acid and phospholipid abnormalities are significant in anorexia nervosa. This will be an important area for future research, and may lead to the development of new interventions.

Abstract
In the last twenty years, several studies have suggested the existence of an association between vegan diets and adolescent menstrual disorders. We share our experience with this problem and a review of the literature on the subject. We conclude that despite the existence of some evidence to the possible association between vegetarian diet and menstrual disorders, it is still not clear if this association is due solely to the vegetarian diet or due to the overall inadequate nutrition with decreased proportions of fat and protein in the diet. We believe that more prospective, well controlled studies are needed to truly explain this association.

Abstract
Emotivist perspectives on moral reasoning hold that emotional reactions precede propositional reasoning. Published findings indicate that, compared with health vegetarians, those who avoid meat on moral grounds are more disgusted by meat [Psychol. Sci. 8 (1997) 67]. If, as per emotivist perspectives, such disgust precedes moral rationales for meat avoidance, then the personality trait of disgust sensitivity should generally be inversely related to meat eating. We surveyed 945 adults regarding meat consumption, reasons for meat avoidance, and disgust sensitivity. Contrary to the emotivist prediction, (a) meat consumption was positively correlated with disgust sensitivity, and (b) individuals who reported avoiding meat for moral reasons were not more sensitive to disgust than those who avoided meat for other reasons. We conclude that moral vegetarianism conforms to traditional explanations of moral reasoning, i.e. moral vegetarians' disgust reactions to meat are caused by, rather than causal of, their moral beliefs.

Abstract
It is the position of the American Dietetic Association and Dietitians of Canada that appropriately planned vegetarian diets are healthful, nutritionally adequate, and provide health benefits in the prevention and treatment of certain diseases. Approximately 2.5% of adults in the United States and 4% of adults in Canada follow vegetarian diets. A vegetarian diet is defined as one that does not include meat, fish, or fowl. Interest in vegetarianism appears to be increasing, with many restaurants and college foodservices offering vegetarian meals routinely. Substantial growth in sales of foods attractive to vegetarians has occurred and these foods appear in many supermarkets. This position paper reviews the current scientific data related to key nutrients for vegetarians including protein, iron, zinc, calcium, vitamin D, riboflavin, vitamin B-12, vitamin A, n-3 fatty acids, and iodine. A vegetarian, including vegan, diet can meet current recommendations for all of these nutrients. In some cases, use of fortified foods or supplements can be helpful in meeting recommendations for individual nutrients. Well-planned vegan and other types of vegetarian diets are appropriate for all stages of the life-cycle including during pregnancy, lactation, infancy, childhood, and adolescence. Vegetarian diets offer a number of nutritional benefits including lower levels of saturated fat, cholesterol, and animal protein as well as higher levels of carbohydrates, fibre, magnesium, potassium, folate, antioxidants such as vitamins C and E, and phytochemicals. Vegetarians have been reported to have lower body mass indices than non-vegetarians, as well as lower rates of death from ischemic heart disease, lower blood cholesterol levels, lower blood pressure, and lower rates of hypertension, type 2 diabetes, and prostate and colon cancer. While a number of federally funded and institutional feeding programs can accommodate vegetarians, few have foods suitable for vegans at this time. Because of the variability of dietary practices among vegetarians, individual assessment of dietary intakes of vegetarians is required. Dietetics professionals have a responsibility to support and encourage those who express an interest in consuming a vegetarian diet. They can play key roles in educating vegetarian clients about food sources of specific nutrients, food purchase and preparation, and any dietary modifications that may be necessary to meet individual needs. Menu planning for vegetarians can be simplified by use of a food guide that specifies food groups and serving sizes.

Abstract
The purpose of this study was to determine whether differences exist in eating attitudes and behaviors of vegetarian and nonvegetarian college women. The Eating Attitudes Test (EAT) and a questionnaire were used to gather information on eating attitudes and behaviors of 143 female college students. Thirty participants were self-reported vegetarians, and 113 participants were nonvegetarians. There was no significant difference between the vegetarians and nonvegetarians in height, weight, age, or body mass index. The median EAT score of the vegetarians (16.5) was significantly higher (P<.0001) than that of the nonvegetarians (9.0). A significantly higher (P<.0001) proportion of the vegetarians (37%) compared with nonvegetarians (8%) had EAT scores greater than 30 (indicating eating disorder risk). There was no difference in supplement use or meal skipping between the two groups. In conclusion, self-reported vegetarian college women may be more likely to display disordered eating attitudes and behaviors than nonvegetarians.

Abstract
As a rule, children and most adults eat what they like and leave the rest. They like and consume foods high in fat and sugar. Parental behaviour shapes food acceptance, and early exposure to fruit and vegetables or to foods high in energy, sugar and fat is related to children's liking for, and consumption of, these foods. Some parents are imposing child-feeding practices that control what and how much children eat. However, over-control can be counter-productive, teaching children to dislike the very foods we want them to consume, and generally undermining self-regulation abilities. The external environment is also important, with concerns expressed about food advertising to children and girls dieting for an ideal thin body shape. Up to one-quarter of young adolescent girls report dieting to lose weight, their motivation driven by weight and shape dissatisfaction. For some, dieting and vegetarianism are intertwined and both legitimised as healthy eating. For others, striving for nutritional autonomy, the choice of less-healthy foods is not just because of their taste, but an act of parental defiance and peer solidarity. The determinants of what children choose to eat are complex, and the balance changes as children get older. A better understanding is crucial to informing how we might modify nutritional behaviour. Adults occupy a central position in this process, suggesting that children should be neither the only focus of nutritional interventions nor expected to solve the nutritional problems with which adults around them are continuing to fail.

Abstract
Eating disorders are one of the rare psychiatric disorders with a large preponderance of female patients. The other articles in this issue review eating disorders in children and adolescents and focus primarily on female patients. This article reviews the eating disorders that occur in male children and teenagers, including anorexia nervosa, bulimia nervosa, binge eating disorder, a subtype of body dysmorphic disorder named muscle dysmorphobia, and obesity. This article reviews subgroups of boys who are at higher risk for developing eating disorders. The article commences with the difference in male perceptions of body image and dieting behaviors.

Abstract
PURPOSE To examine the prevalence of adolescents' vegetarianism in a multiethnic, urban population, and its correlates with demographic, personal, weight-related, and behavioral factors. METHODS Self-report and anthropometric data were collected from a representative sample of 4746 adolescents from 31 public middle schools and high schools in the Twin Cities area of Minnesota. Students answered questions concerning vegetarianism, food and weight, and health behaviors. Height and weight were directly measured. Comparisons were made between self-reported vegetarians and nonvegetarians; these analyses also assessed gender and race/ethnicity interactions. In the second set of analyses, demographic and behavioral characteristics of more restricted and semi-vegetarians were examined. Analyses were done by logistic regression. RESULTS Teenage vegetarians comprise about 6% of the sample. The vegetarians were more likely than nonvegetarians to be female, not black, weight- and body-conscious, dissatisfied with their bodies, and involved in a variety of healthy and unhealthy weight control behaviors. Vegetarians more often reported having been told by a physician that they had an eating disorder and were more likely to have contemplated and attempted suicide. Vegetarian males were found to be an especially high risk group for unhealthy weight control practices. Few ethnic group differences among vegetarians were noted. Adolescents who did not eat chicken and fish were at lower risk than those who also ate chicken and fish. CONCLUSIONS Adolescent vegetarians are at greater risk than others for involvement in unhealthy and extreme weight control behaviors. Vegetarian males are at particularly high risk. Vegetarianism among adolescents may therefore be a signal for preventive intervention. Adolescents who choose to become vegetarians may also need to learn how to healthfully do so.

Abstract
OBJECTIVE To determine the prevalence of vegetarianism and compare food habits among vegetarian and omnivorous adolescents in Sweden and Norway. DESIGN Cross-sectional study by questionnaire in Sweden and Norway to gather information about food habits. SETTING The municipalities of Umeå and Stockholm in Sweden, and Bergen in Norway. SUBJECTS In total 2041 ninth-grade students (578 from Umeå, 504 from Stockholm and 959 from Bergen), mean age 15.5 years, were included. The response rate was 95% in Umeå, 91% in Stockholm and 83% in Bergen. RESULTS There was a significantly higher prevalence of vegetarianism in Umeå (15.6%) than in Stockholm (4.8%) and Bergen (3.8%). Vegetarians generally wanted more information about a healthy diet and vegetarian females ate dietary supplements to prevent deficiencies more often than omnivorous females (P < 0.01). The young male vegetarians more or less excluded animal products from their diet without changing their food frequency intake or modifying their dietary habits in other respects, while the young female vegetarians more often consumed vegetables and dietary supplements (P < 0.05). However, there was no difference between the intake of fruits/berries, alcoholic beverages, ice cream, sweets/chocolates and fast foods by vegetarians compared with omnivores. CONCLUSIONS There were three to four times more vegetarians in Umeå than in Stockholm and Bergen. The food habits of the young vegetarians differed from those of omnivorous adolescents and also in some respects from previously published comparative studies of vegetarians' and omnivores' food habits. It is uncertain whether the health benefits shown in previous studies on vegetarianism will be experienced by this young generation of vegetarians.

Abstract
This article reviews research on the growth and nutrient intake of vegan children and provides guidelines for counselling parents of vegan children. Although diets of vegan children meet or exceed recommendations for most nutrients, and vegan children have higher intakes of fiber and lower intakes of total fat, saturated fat, and cholesterol than omnivore children, some studies indicate that they may be low in calcium. In addition, bioavailability of zinc and iron from plant foods can be low. Protein needs are slightly higher for vegan children but are easily met with a varied diet that provides adequate energy. Special attention should be given to dietary practices that enhance absorption of zinc and iron from plant foods. Further, good sources of the omega-3 fatty acid linolenic acid should be emphasized to enhance synthesis of the long-chain fatty acid docosahexanoic acid. Dietetics professionals who counsel vegan families should help parents identify good sources of vitamin B-12, riboflavin, zinc, calcium and, if sun exposure is not adequate, vitamin D. This should not be problematic, due to the growing number and availability of fortified vegan foods that can help children meet all nutrient needs. Therefore, with appropriate food choices, vegan diets can be adequate for children at all ages.

Abstract
OBJECTIVE To compare relative weight, weight loss efforts and nutrient intakes among similarly health-conscious vegetarian, past vegetarian and nonvegetarian premenopausal women. METHODS Demographic data, lifestyle practices and weight loss efforts (by questionnaire), body mass index (BMI;kg/m2) and dietary intake (via multiple-pass 24-hour diet recall) were compared in a convenience sample of 90 current vegetarians, 35 past vegetarians and 68 nonvegetarians. RESULTS Age (31.9 +/- 8.8), educational attainment, smoking status, alcohol use, physical activity and perceived health status were similar among the three groups of women. BMI did not differ by dietary pattern and averaged 23.7 +/- 4.7 for all women combined. Participants had intentionally lost > or = 10 pounds a mean of 2.1 times, and 39% of women perceived themselves to be overweight; again, no differences were observed among dietary groups. Dietary intakes of vegetarians and current nonvegetarians were consistent with current recommendations for macronutrient composition (< 30% fat, < 10% saturates). Compared to current nonvegetarians, current vegetarians had lower intakes of protein, saturated fat, cholesterol, niacin, vitamins B12 and D, and higher fiber and magnesium intakes. Vegetarians' mean vitamin B12 and D intakes were well below recommendations. CONCLUSIONS Relative weight and weight loss efforts do not differ by dietary pattern among similarly health-conscious vegetarian and nonvegetarian women. The only differences in nutrient intake with potential health implications were vitamins D and B12.

Abstract
The goals of manual-based cognitive-behavioral therapy (CBT) and nutritional counseling for eating disorders are similar, namely, eliminating dysfunctional patterns of eating. Modifying these behaviors requires specific therapeutic expertise in the principles and procedures of behavior change that is not typically part of the training of nutritionists and dieticians or mental health professionals without specific expertise. We discuss ways in which principles of behavior change can be applied to eating disorders by non-CBT experts. Specific nutritional rehabilitation programs have the potential to augment CBT in addressing the array of appetitive abnormalities present in eating disorder patients. The dysfunctional appetitive, hedonic, and metabolic characteristics of patients with bulimia nervosa (BN) and binge eating disorder are reviewed. These abnormalities constitute potential target areas that might be more fully addressed by nutritional interventions designed to restore normal appetitive function.
