Background: Given the growing popularity of plant‐based diets, this study investigated the dietary habits and self‐reported health outcomes of health‐conscious adults consuming plant‐based diets. Methods: A cross‐sectional online survey (n = 315) was distributed to members of Plant‐Based Health Professionals UK, a community interest company. Dietary intake was assessed through a food frequency questionnaire. Data were summarised descriptively. Dietary habits among respondents following a whole food plant‐based (WFPB) and vegan diet were compared using hypothesis tests. Results: Respondents reported following a WFPB (61%), vegan (28%) and semi plant‐based (11%) diet. Median time on current dietary pattern was 5 years. Daily or more frequent consumption was reported for the following foods: fruits 77%, berries 51%, green vegetables 48%, cruciferous vegetables 45%, other vegetables 64%, beans/legumes 41%, whole grains 62%, nuts and all seeds 63%. Consumption of ultra‐processed foods and plant‐based meat alternatives was low. About 93% of those on a WFPB or vegan diet supplemented with vitamin B12 and 61% with vitamin D. The median body mass index was 22.4 kg/m2. Fifty per cent of participants reported weight loss after adopting a plant‐based diet, with a median loss of 6.4 kg. Thirty‐five per cent reported reversing or improving an underlying health condition, and 15% were able to stop or reduce prescribed medication use as a result of dietary changes. Conclusions: This study suggests that a well‐planned plant‐based diet is achievable and sustainable in a community setting and can be associated with health benefits. How to best encourage such sustainable diets among the broad population requires further research. Key points: Dietary intakes were consistent with a high‐quality diet, with a variety of whole plant foods consumed and minimal ultraprocessed foods, refined grains, sugar‐sweetened beverages and meat alternatives.Whole food plant‐based (WFPB) participants followed, on average, healthier diets than vegan participants and engaged in more physical activity.In this plant‐based population, there were indicators of favourable health outcomes such as low body mass index (BMI) and low levels of common chronic conditions.Participants reported improvements in a range of health conditions and a reduction in medication as a result of adopting plant‐based diets, with some requiring further research.This study suggests that a well‐planned plant‐based diet is achievable and sustainable in a community setting and can be associated with health benefits.

The current study investigated meat‐reducers' (vegan, vegetarian, and flexitarian) dietary identities using an identity process approach. Drawing on identity development theories, we aimed to (i) classify meat‐reducers from the United Kingdom and United States (N = 375) based on their level of identity exploration and commitment, and (ii) examine the effect of dietary identity status on diet and group‐based behaviours. Findings demonstrated evidence for three identity clusters: achieved (high exploration and high commitment), foreclosed (lower exploration and higher commitment), and diffused (low exploration and low commitment) meat‐reducers. Vegans were more likely to display an achieved dietary identity, whereas the majority of flexitarians indicated a diffused identity. More importantly, identity status had significant effects on all outcome measures, with achieved meat‐reducers reporting greatest dietary strictness, greatest centrality and private regard, but lowest public regard, as well as most negative attitudes towards meat‐eaters and greatest activism. We discuss how investigating dietary identities with a 'process framework' may point to a more inclusive view of social identities among people who follow a plant‐based diet. [ABSTRACT FROM AUTHOR]

Background Substantial evidence supports the inverse association between adherence to healthy dietary patterns and frailty risk. However, the role of plant-based diets, particularly their quality, is poorly known. Objective To examine the association of two plant-based diets with incidence of physical frailty in middle-aged and older adults. Design Prospective cohort. Setting United Kingdom Subjects 24,996 individuals aged 40–70 years, followed from 2009–12 to 2019–22. Methods Based on at least two 24-h diet assessments, we built two diet indices: (i) the healthful Plant-based Diet Index (hPDI) and (ii) the unhealthful Plant-based Diet Index (uPDI). Incident frailty was defined as developing ≥3 out of 5 of the Fried criteria. We used Cox models to estimate relative risks (RR), and their 95% confidence interval (CI), of incident frailty adjusted for the main potential confounders. Results After a median follow-up of 6.72 years, 428 cases of frailty were ascertained. The RR (95% CI) of frailty was 0.62 (0.48–0.80) for the highest versus lowest tertile of the hPDI and 1.61 (1.26–2.05) for the uPDI. The consumption of healthy plant foods was associated with lower frailty risk (RR per serving 0.93 (0.90–0.96)). The hPDI was directly, and the uPDI inversely, associated with higher risk of low physical activity, slow walking speed and weak hand grip, and the uPDI with higher risk of exhaustion. Conclusions In British middle-age and older adults, greater adherence to the hPDI was associated with lower risk of frailty, whereas greater adherence to the uPDI was associated with higher risk.

Reducing animal product consumption has benefits for population health and the environment. The relationship between vegetarianism and mental health, however, remains poorly understood. This study explores this relationship in a nationally representative cohort in Great Britain. We use data from the 1970 British Cohort Study, which collected information on vegetarianism at age 30 in 2000 (n = 11,204) and psychological distress (PD) at ages 26, 30, 34, 42, and 46–48 in 2016/18. We first developed a statistical adjustment strategy by regressing PD at age 30 on vegetarianism and 14 confounders measured at ages 10 and 26. We then ran multilevel growth curve models, testing whether within-person changes in PD between ages 30 and 46–48 differed by vegetarianism, before and after statistical adjustment. At age 30, 4.5 % of participants reported being vegetarian. In the cross-sectional models at age 30, vegetarians reported more distress compared with non-vegetarians in bivariate analysis (b = 0.30, 95%CI 0.09, 0.52), but this difference disappeared in the fully-adjusted model (b = 0.02, 95%CI −0.17, 0.21). In the longitudinal models between ages 30 and 46/48, there were no differences in within-person changes in psychological distress between vegetarians and non-vegetarians (p =.723). Sensitivity analyses using red meat consumption yielded similar findings. In this British cohort, vegetarianism at age 30 was not associated with changes in psychological distress during mid-adulthood. Since psychological distress in early adulthood predicted vegetarianism at age 30, more studies are needed to disentangle the progression of this relationship over the life-course. • Most studies on vegetarianism and mental health are methodologically weak. • Vegetarianism at age 30 was not associated with subsequent changes in psychological distress in the 1970 British Cohort Study. • Vegetarianism and mental health may still be related during the transition to aduthood.

A substantial body of evidence points to the heritability of dietary preferences. While vegetarianism has been practiced for millennia in various societies, its practitioners remain a small minority of people worldwide, and the role of genetics in choosing a vegetarian diet is not well understood. Dietary choices involve an interplay between the physiologic effects of dietary items, their metabolism, and taste perception, all of which are strongly influenced by genetics. In this study, we used a genome-wide association study (GWAS) to identify loci associated with strict vegetarianism in UK Biobank participants. Comparing 5,324 strict vegetarians to 329,455 controls, we identified one SNP on chromosome 18 that is associated with vegetarianism at the genome-wide significant level (rs72884519, β = -0.11, P = 4.997 x 10−8), and an additional 201 suggestively significant variants. Four genes are associated with rs72884519: TMEM241, RIOK3, NPC1, and RMC1. Using the Functional Mapping and Annotation (FUMA) platform and the Multi-marker Analysis of GenoMic Annotation (MAGMA) tool, we identified 34 genes with a possible role in vegetarianism, 3 of which are GWAS-significant based on gene-level analysis: RIOK3, RMC1, and NPC1. Several of the genes associated with vegetarianism, including TMEM241, NPC1, and RMC1, have important functions in lipid metabolism and brain function, raising the possibility that differences in lipid metabolism and their effects on the brain may underlie the ability to subsist on a vegetarian diet. These results support a role for genetics in choosing a vegetarian diet and open the door to future studies aimed at further elucidating the physiologic pathways involved in vegetarianism.

Our study aimed to explore vegan mothers' experiences and decision-making processes when feeding their children (up to 3 years old). We conducted a qualitative photo-elicitation interview study in the United Kingdom. Eight vegan mothers provided 5 photographs of food choices they had made for their children and completed online photo-elicitation interviews to discuss these images. Data were transcribed verbatim and analyzed using reflexive thematic analysis. Five themes were developed: role modeling eating behavior, shared decision-making, nutritional guidance for vegan parents, fear of judgment for being vegan, and desire for convenience. Findings illustrate the complexity of the decision-making process and highlight the need for targeted resources for vegan parents. There is a need for awareness raising and training for health care professionals and the development of vegan-specific child-feeding resources to facilitate the provision of evidence-based nutritional guidance for vegan parents.

Iodine is essential for thyroid hormone synthesis. Individuals adhering to vegan and vegetarian diets have been found to be vulnerable to iodine deficiency. Yet, iodine has not been monitored in these groups across time. This study aims to investigate iodine status, intake and knowledge in vegans, vegetarians and omnivores and determine changes between 2016–2017 and 2019. Dietary intake (µg/d) was estimated by 3-d food diaries and iodine FFQ. Urinary iodine concentration, analysed by inductively coupled plasma mass spectrometry, assessed iodine status according to WHO criteria. Iodine knowledge was scored by an adapted questionnaire. IBM SPSS was used for statistical analysis. Ninety-six adults (18–60 years) were recruited in October 2016–2017 (vegans: 12; vegetarians: 5; omnivores: 43) and June 2019 (vegans: 7; vegetarians: 10;omnivores: 19). Median dietary iodine was below the Reference Nutrient Intake for all groups. Vegans and vegetarians had the lowest iodine intake. Vegans had significantly lower iodine intake than omnivores (2016–2017, P = 0 032; 2019, P = 0 001). Omnivores had the highest iodine status (2016–2017, 79 4 µg/l; 2019, 72 4 µg/l) and vegans the lowest (2016–2017, 31 2 µg/l; 2019, 12 2 µg/l). Iodine knowledge was poor but did not differ between dietary groups (2016–2017, P = 0 219; 2019, P = 0 532). Vegans and vegetarians continue to be at risk of iodine deficiency. Further, iodine intake in the UK is poor independent of dietary choice. Iodine education is needed along with research into improving iodine nutrition at national level. [ABSTRACT FROM AUTHOR]

Two studies compared omnivores' and veg*ns' attitudes and dehumanization tendencies toward each other and identified the social psychological factors explaining them. Study 1 (N = 208, Italians) showed that veg*ns' hold less positive attitudes toward omnivores than the reverse, and attributed to them less human uniqueness and nature; these differences were explained by veg*ns' stronger identification with the ingroup and higher perceptions of reproach from the outgroup, even if omnivores' higher levels of social dominance orientation worsened their attitude toward veg*ns. Study 2 (preregistered, N = 200, mostly from UK) overall replicated Study 1 findings at the explicit level. Interestingly, omnivores' and veg*ns' implicit attitudes were equally positive (but less positive than self‐reported attitudes) and not predicted by the same mediators associated with the explicit measures. This work suggests that neither veg*ns nor omnivores hold negative attitudes toward each other: they were both positive or neutral toward the outgroup, even if at the explicit level this positivity is greater for omnivores.

Background: In many Westernised countries, children do not consume a sufficient amount of vegetables for optimal health and development. Child-feeding guidelines have been produced to address this, but often only promote offering vegetables at midday/evening meals and snack times. With guidance having limited success in increasing children's vegetable intake at a population level, novel approaches to address this must be developed. Offering vegetables to children at breakfast time in nursery/kindergarten settings has the potential to increase children's overall daily vegetable consumption as children typically attend nursery/kindergarten and many routinely eat breakfast there. However, the feasibility and acceptability of this intervention (Veggie Brek) to children and nursery staff has not been investigated. Methods: A feasibility and acceptability cluster randomised controlled trial (RCT) was undertaken in eight UK nurseries. All nurseries engaged in one-week baseline and follow-up phases before and after an intervention/control period. Staff in intervention nurseries offered three raw carrot batons and three cucumber sticks alongside children's main breakfast food each day for three weeks. Control nurseries offered children their usual breakfast. Feasibility was assessed by recruitment data and nursery staff's ability to follow the trial protocol. Acceptability was assessed by children's willingness to eat the vegetables at breakfast time. All primary outcomes were assessed against traffic-light progression criteria. Staff preference for collecting data via photographs versus using paper was also assessed. Further views about the intervention were obtained through semi-structured interviews with nursery staff. Results: The recruitment of parents/caregivers willing to provide consent for eligible children was acceptable at 67.8% (within the amber stop–go criterion) with 351 children taking part across eight nurseries. Both the feasibility and acceptability of the intervention to nursery staff and the willingness of children to consume the vegetables met the green stop–go criteria, with children eating some part of the vegetables in 62.4% (745/1194) of instances where vegetables were offered. Additionally, staff preferred reporting data using paper compared to taking photographs. Conclusions: Offering vegetables to children at breakfast time in nursery/kindergarten settings is feasible and acceptable to children and nursery staff. A full intervention evaluation should be explored via a definitive RCT. Trial registration: NCT05217550. [ABSTRACT FROM AUTHOR]

Yoga is a spiritual discipline originating from ancient India. Most notably, yoga has links with Hinduism, Buddhism, and Jainism. This research explores UK yoga teachers' attitudes toward plant-based diets and beliefs about the moral status of farmed animals. It uses qualitative interviews as the second phase of a mixed-methodology study. In the first phase, an online questionnaire found that over two thirds of UK yoga teachers believed a plant-based diet was most aligned with their yoga practice due to the teaching of ahimsa , or non-harm. Nevertheless, over 70 % were not following a plant-based diet. Interviews revealed this dissonance was related to views about the necessity of consuming animal products for health, especially when pregnant, breastfeeding, or nourishing growing children. The communal nature of eating also meant that family moderated dietary ideals. Interviews further revealed an alternative conception of ahimsa , permitting the consumption of animals in order to prioritize personal non-harm. [ABSTRACT FROM AUTHOR]

People are increasingly concerned about how meat affects the environment, human health, and animal welfare, yet eating and enjoying meat remains a norm. Unsurprisingly, many people are ambivalent about meat--evaluating it as both positive and negative. Here, we propose that meat-related conflict is multidimensional and depends on people's dietary group: Omnivores' felt ambivalence relates to multiple negative associations that oppose a predominantly positive attitude towards meat, and veg*ans' ambivalence relates to various positive associations that oppose a predominantly negative attitude. A qualitative study (N = 235; German) revealed that omnivores and veg*ans experience meat-related ambivalence due to associations with animals, sociability, sustainability, health, and sensory experiences. To quantify felt ambivalence in these domains, we developed the Meat Ambivalence Questionnaire (MAQ). We validated the MAQ in four pre-registered studies using self-report and behavioral data (N = 3,485; German, UK, representative US). Both omnivores and veg*ans reported meat-related ambivalence, but with differences across domains and their consequences for meat consumption. Specifically, ambivalence was associated with less meat consumption in omnivores (especially sensory-/animal-based ambivalence) and more meat consumption in veg*ans (especially sensory-/socially-based ambivalence). Network analyses shed further light on the nomological net of the MAQ while controlling for a comprehensive set of determinants of meat consumption. By introducing the MAQ, we hope to provide researchers with a tool to better understand how ambivalence accompanies behavior change and maintenance. [ABSTRACT FROM AUTHOR]

This paper explores the historical development of protein-enhanced foods in Great Britain and how they were marketed by food manufacturers to convince consumers that protein was essential to maintaining a healthy lifestyle. It focuses particularly on Plasmon and Emprote – the two biggest brands of the early twentieth century – and uses multimodal critical discourse analysis to identify how semiotic resources are used to embed products in scientific rationality, promote health discourses and develop concepts of masculinity in accordance with the two strands of the physical culture movement. It argues that, just as today, food manufacturers capitalized upon the growing middle-class interest in functional foods and presented protein as an "elixir" that consumers should take to safeguard their health, the health of their families and the state of the nation. Overall, this study demonstrates that, even with today's strict legislation on food packaging and advertising, protein food manufacturers still use similar techniques to sell their products. In gaining a better understanding of the historical use of semiotic resources in food advertising, we can assess the legitimacy of current food regulations and ensure that people make informed choices when shopping.

Background: Prospective studies have shown differences in some disease risks between vegetarians and nonvegetarians, but the potential biological pathways are not well understood.Objectives: We aimed to assess differences in concentrations of biomarkers related to disease pathways in people with varying degrees of animal foods exclusion.Methods: The UK Biobank recruited 500,000 participants aged 40-69 y (54.4% women) throughout the United Kingdom in 2006-2010. Blood and urine were collected at recruitment and assayed for more than 30 biomarkers related to cardiovascular diseases, bone and joint health, cancer, diabetes, renal disease, and liver health. In cross-sectional analyses, we estimated adjusted geometric means of these biomarkers by 6 diet groups (regular meat eaters, low meat eaters, poultry eaters, fish eaters, vegetarians, vegans) in 466,058 white British participants and 2 diet groups (meat eaters, vegetarians) in 5535 British Indian participants.Results: We observed differences in the concentrations of most biomarkers, with many biomarkers showing a gradient effect from meat eaters to vegetarians/vegans. Of the largest differences, compared with white British regular meat eaters, white British vegans had lower C-reactive protein [adjusted geometric mean (95% CI): 1.13 (1.03, 1.25) compared with 1.43 (1.42, 1.43) mg/L], lower low-density lipoprotein cholesterol [3.13 (3.07, 3.20) compared with 3.65 (3.65, 3.65) mmol/L], lower vitamin D [34.4 (33.1, 35.9) compared with 44.5 (44.4, 44.5) nmol/L], lower serum urea [4.21 (4.11, 4.30) compared with 5.36 (5.36, 5.37) mmol/L], lower urinary creatinine [5440 (5120, 5770) compared with 7280 (7260, 7300) μmol/L], and lower γ-glutamyltransferase [23.5 (22.2, 24.8) compared with 29.6 (29.6, 29.7) U/L]. Patterns were mostly similar in British Indians, and results were consistent between women and men.Conclusions: The observed differences in biomarker concentrations, including lower C-reactive protein, lower LDL cholesterol, lower vitamin D, lower creatinine, and lower γ-glutamyltransferase, in vegetarians and vegans may relate to differences in future disease risk.

Vegetarianism and veganism are increasingly popular. The Food Standards Agency, biennial Food and You Survey of adults aged 16 years and over living in the UK, found that between 2012 and 2018 the proportion of people who reported never consuming dairy products had increased from 2% to 5%. However, veganism risks development of vitamin B12 deficiency as it is not available from plant sources. Moreover, its impact may be slow to be detected because body stores of vitamin B12 can last years. There is currently no published guidance on antenatal diagnosis and management of vitamin B12 deficiency. This paper reviews the metabolism, diagnosis and treatment of vitamin B12 in pregnancy. It concludes that national screening policymakers should consider introducing screening for B12 deficiency into the Antenatal and Newborn Screening Programmes for mothers and their infants if at risk of vitamin B12 deficiency. In the interim, national policy should be developed for prophylactic vitamin B12 supplementation in high‐risk groups around the time of pregnancy. [ABSTRACT FROM AUTHOR]

Rather than viewing these developments as mere fads spurred by charlatans with fabricated medical credentials, Stark argues that hormone products were an aspect of interwar emphasis in direct-to-consumer marketing. In the twentieth-century British marketplace of rejuvenation, consumers could select amongst a multitude of desirable products and therapies offering the prospect of enhancing youthfulness. Marketers amped up their product's rejuvenation narratives, deploying advertising strategies that emphasized the pretense of medical or scientific credentials and outlining rejuvenation as a life-long process.

Accessible summary: People with learning disabilities who are vegetarian or vegan in this study choose not to eat meat because of their love of animals, the concern for their welfare and a dislike of them being killed to eat.People with learning disabilities in this study did not think other people with learning disabilities are aware that animals are killed for meat and do not have the information to make an informed choice about eating meat.Participants in this study have supportive staff and families who help them to cook and eat a vegetarian or vegan diet.Some people with learning disabilities worry about the healthiness and fat content of meat, and also diseases that animals may have which go into meat. Background: Adopting a vegetarian diet is becoming increasingly popular within the UK, for reasons such as perceived health benefits and concerns over animal welfare. The study explores attitudes towards vegetarianism/veganism among adults with learning disabilities. Materials and Methods: Semi‐structured interviews were conducted with eight people with learning disabilities who did not eat meat across the UK. Results: Participants who adopted a meat‐free diet did so predominantly for animal welfare. Participants cared passionately about the welfare of animals but were reluctant to advocate their lifestyle to other people with learning disabilities, where they are in the minority for their dietary choices. Participants felt most people with learning disabilities were not made aware of the reality that animals are killed for food and that they should have accessible information to make an informed choice about whether to eat meat. Conclusions: Holding the identity as a vegetarian could potentially facilitate integration into mainstream organisations where people hold similar ethical beliefs; however, this is unlikely unless organisations increase their inclusivity such as providing accessible information.

Research suggests that eating vegetables benefits both human health and the environment. However, in the UK, very few people are eating enough vegetables. This is contributing to the global burden of diet‐related disease and associated costs, as well as undermining the possibility of a sustainable UK food system. The Peas Please initiative was launched in 2017 to encourage organisations and businesses across the food system to pledge their commitment to helping the British public increase their vegetable consumption. Since the implementation of the Peas Please initiative 95 organisations have pledged to support Peas Please and, at the time of writing, an additional 89.9 million portions of vegetables have been grown, served and sold by pledgers. This article describes the Peas Please initiative and its rationale, highlights some of the key outcomes of the programme, and outlines next steps for increasing commitment to the programme.

Sustainable diets are proposed as a means to improve public health and food security and to reduce the impact of the food system on the environment. Guidance around sustainable diets includes a reduction of animal products in order to move towards a more plant‐based diet, meaning that plant‐originated foods are a predominant, but not the sole component of a diet. The main principles of a sustainable diet (as provided by the Food and Agriculture Organization of the United Nations/World Health Organization) are to consume a variety of unprocessed or minimally processed foods, mainly as wholegrains, pulses, fruits and vegetables, with moderate amounts of eggs, dairy, poultry and fish and modest amounts of ruminant meat, which are consistent with the current UK healthy eating recommendations (e.g. Eatwell Guide). The aim of this review was twofold: (i) to discuss public health challenges associated with consumers' knowledge regarding protein sustainability, healthier protein sources and protein requirements, and (ii) to review potential approaches to facilitate the shift towards a more sustainable diet. Consumers would benefit from receiving clear guidance around how much protein is needed to meet their daily requirements. The public health message directed to a consumer could highlight that desired health outcomes, such as muscle protein synthesis and weight control, can be achieved with both sources of protein (i.e. animal and plant‐based), and that what is more important is the nature of the 'protein package'. Health promotion and education around the benefits of plant‐based protein could be one of the strategies encouraging the wider population to consider a shift towards a predominantly plant‐based diet.

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

Background There may be differences in hematological parameters between meat-eaters and vegetarians. Objective The aim of this study was to perform cross-sectional analyses of hematological parameters by diet group in a large cohort in the United Kingdom. Methods A complete blood count was carried out in all UK Biobank participants at recruitment (2006–2010). We examined hemoglobin, red and white blood cell counts, and platelet counts and volume in regular meat eaters (>3 times/wk of red/processed meat consumption, n  = 212,831), low meat eaters (n  = 213,092), poultry eaters (n  = 4815), fish eaters (n  = 10,042), vegetarians (n  = 6548), and vegans (n  = 398) of white ethnicity and meat eaters (n  = 3875) and vegetarians (n  = 1362) of British Indian ethnicity. Results In both white and British Indian populations, compared with regular meat eaters (or meat eaters in Indians), the other diet groups had up to 3.7% lower age-adjusted hemoglobin concentrations (difference not significant in white vegan women) and were generally more likely to have anemia (e.g. 8.7% of regular meat eaters compared with 12.8% of vegetarians in white premenopausal women; P  < 0.05 after Bonferroni correction). In the white population, compared with regular meat eaters, all other diet groups had lower age- and sex-adjusted total white cells, neutrophils, lymphocytes, monocytes, and eosinophils (P -heterogeneity < 0.001 for all), but basophil counts were similar across diet groups; in British Indians, there was no significant difference in any of the white blood cell counts by diet group. Compared with white regular meat eaters, the low meat eaters, poultry eaters, fish eaters, and vegans had significantly lower platelet counts and higher platelet volume, whereas vegetarians had higher counts and lower volume. Compared with British Indian meat eaters, vegetarians had higher platelet count and lower volume. Conclusions In the UK Biobank, people with low or no red meat intake generally had lower hemoglobin concentrations and were slightly more likely to be anemic. The lower white blood cell counts observed in low and non-meat eaters, and differences in mean platelet counts and volume between diet groups, warrant further investigation. This observational study was registered at http://www.isrctn.com/ as ISRCTN10125697. [ABSTRACT FROM AUTHOR]

In many countries around the world, significant proportions of consumers report intentions to reduce their meat consumption. If followed through on, the intentions of these meat reducers could yield substantial environmental, health and animal welfare benefits. Existing research warns, however, that good intentions often go astray. In the current study, we examine the prevalence of intentions to reduce meat consumption in a representative sample of 1492 UK residents. We then investigate the situational correlates of intention-behaviour gaps in meat consumption among a group of 633 people with intentions to reduce their intake in a longitudinal survey involving event reconstruction exercises. Through these exercises, we collect data on the objective situational cues and psychological situational characteristics that predict when this group desired, ate and regretted eating meat during 2777 meal episodes. The results indicate that situational factors are predictive of the range of outcomes of interest. Situations that lend themselves to hedonic, rather than instrumental style, consumption, (e.g., non-routine meals, when the situation is perceived as being pleasant and when taste and craving are important decision factors), eating outside the home in cafés and restaurants and over at family or friend's homes and eating in the presence of others who are eating meat when are particularly predictive of intention-behaviour gaps. The findings highlight the need for intervention work which targets these situations to help meat reducers act as they intend. • We examine the prevalence of intentions to reduce meat consumption in a representative sample of 1492 UK residents. • We investigate the objective situational cues and psychological situational characteristics that predict when a sample of 633 meat reducers group desired, ate and regretted eating meat during 2777 meal episodes. • We find that situations that lend themselves to hedonic, rather than instrumental style, consumption, eating outside the home and eating in the presence of others who are eating meat when are particularly predictive of intention-behaviour gaps.

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. [ABSTRACT FROM AUTHOR]

Background: A detailed description of anthropometric and physiologic characteristics of persons in different diet groups is lacking. Objective: We aimed to perform cross-sectional analyses of diet group with anthropometric and physiologic characteristics in a large cohort in the United Kingdom. Design: The UK Biobank recruited ~500,000 middle-aged participants throughout the United Kingdom in 2006-2010. Anthropometric indexes (height, weight, waist and hip circumference, body composition) and other physiologic characteristics (heel bone mineral density, grip strength, blood pressure, pulse rate) were measured following standardized protocols.We estimated the age-adjusted means of each characteristic in 6 diet groups (198,166 regular meat eaters, 199,784 low meat eaters, 4381 poultry eaters, 9674 fish eaters, 6366 vegetarians, and 378 vegans) in white women and men, and in 2 diet groups (3322 meat eaters and 1186 vegetarians) in British Indian women and men. Results: In white women, after adjustment for age and compared with regular meat eaters, non--red meat eaters had lower adiposity (e.g., 4.5% lower body fat in vegan women) and lower systolic and diastolic blood pressure (-4.2 and 13.3 mm Hg, respectively), and generally lower heel bone mineral density t-score (10.26). Patterns of differences by diet group were similar in white men. In the Indian population, compared with meat eaters, vegetarian women were shorter (11.1 cm) and had lower lean mass (10.5 kg), and both vegetarian women and men had lower grip strength (11.3 and 11.4 kg, respectively). No significant differences in the other characteristics were observed. Conclusions: Differences in anthropometric and physiologic characteristics were observed across diet groups in white participants, but fewer differences were observed in British Indian participants. The observed differences may be important as intermediate markers of long-term health in different diet groups. This observational study was registered at http://www.isrctn.com/ as ISRCTN10125697.

The article presents the views of diet specialists on bringing up children on a vegan diet in Great Britain. Aisling Pigott claims that a vegan diet is applicable for anyone provided it is based on thorough nutrition knowledge and is well planned, while Heather Russell notes that all the nutrients in a healthy vegan diet for children can be provided through careful research and planning. On other hand, Carrrie Ruxton states that children require higher nutrients than a vegan diet can provide.

Objective: There is evidence to suggest that individual components of dietary intake are associated with depressive symptoms. Studying the whole diet, through dietary patterns, has become popular as a way of overcoming intercorrelations between individual dietary components; however, there are conflicting results regarding associations between dietary patterns and depressive symptoms. We examined the associations between dietary patterns extracted using principal component analysis and depressive symptoms, taking account of potential temporal relationships.Design: Depressive symptoms in parents were assessed using the Edinburgh Postnatal Depression Scale (EPDS) when the study child was 3 and 5 years of age. Scores >12 were considered indicative of the presence of clinical depressive symptoms. Diet was assessed via FFQ when the study child was 4 years of age.Setting: Longitudinal population-based birth cohort.Subjects: Mothers and fathers taking part in the Avon Longitudinal Study of Parents and Children when their study child was 3-5 years old.Results: Unadjusted results suggested that increased scores on the 'processed' and 'vegetarian' patterns in women and the 'semi-vegetarian' pattern in men were associated with having EPDS scores ≥13. However, after adjustment for confounders all results were attenuated. This was the case for all those with available data and when considering a sub-sample who were 'disease free' at baseline.Conclusions: We found no association between dietary patterns and depressive symptoms after taking account of potential confounding factors and the potential temporal relationship between them. This suggests that previous studies reporting positive associations may have suffered from reverse causality and/or residual confounding. [ABSTRACT FROM AUTHOR]

Dietary nitrate is mainly obtained from vegetables, especially green leafy vegetables and beetroot. As a result of early research, dietary nitrate is currently viewed as a contaminant linked to increased risks of stomach cancer and methaemoglobinaemia. Consequently, nitrate levels are restricted in certain vegetables and in water supplies to ensure exposure levels remain below an acceptable daily intake of 3.7 mg/kg per d. The average nitrate intake in the UK is approximately 70 mg/d, although some population groups, such as vegetarians, may consume three times that amount. However, recent studies in the last decade suggest that dietary nitrate can significantly reduce systolic blood pressure via the nitrate-nitrite-NO pathway. A small, downward shift in systolic blood pressure across the population could significantly reduce the incidence of hypertension and mortality from CVD such as stroke. Interestingly, vegetarians tend to have lower levels of blood pressure than omnivores and epidemiological studies suggest that vegetarians have lower risks of CVD. Recent evidence is mainly focused on the acute effects of dietary nitrate supplementation and there is a lack of data looking at the chronic effects of high nitrate consumption in humans. Nevertheless, due to potential health benefits, some authors are recommending that nitrate should be considered as a nutrient necessary for health, rather than as a contaminant which needs to be restricted. This review will discuss the emerging role of dietary nitrate in the control of blood pressure and whether there is sufficient evidence to state that nitrate is a 'new' nutrient.

Shorter telomere length (TL) is associated with risk of several age-related diseases and decreased life span, but the extent to which dietary patterns and practices associate with TL is uncertain. This study aimed to investigate the association of dietary patterns and practices and leucocyte TL (LTL). This was a cross-sectional study. Data collected voluntarily from up to 422,797 UK Biobank participants, during 2006-2010. LTL was measured as a ratio of the telomere repeat number to a single-copy gene and was log e -transformed and standardized (z-LTL). Adherence a priori to a Mediterranean-style diet was assessed through the MedDietScore. Principal component analysis was used to a posteriori extract the "Meat" and "Prudent" dietary patterns. Additional dietary practices considered were the self-reported adherence to "Vegetarian" diet, "Eating 5-a-day of fruit and vegetables" and "Abstaining from eggs/dairy/wheat/sugar." Associations between quintiles of dietary patterns or adherence to dietary practices with z-LTL were investigated through multivariable linear regression models (adjusted for demographic, lifestyle, and clinical characteristics). Adherence to the "Mediterranean" and the "Prudent" patterns, was positively associated with LTL, with an effect magnitude in z-LTL of 0.020 SD and 0.014 SD, respectively, for the highest vs the lowest quintile of adherence to the pattern (both P values < 0.05). Conversely, a reversed association between quintile of the "Meat" pattern and LTL was observed, with z-LTL being on average shorter by 0.025 SD (P = 6.12×10–05) for participants in the highest quintile of the pattern compared with the lowest quintile. For adherents to "5-a-day" z-LTL was on average longer by 0.027 SD (P = 5.36×10–09), and for "abstainers," LTL was shorter by 0.016 SD (P = 2.51×10–04). The association of LTL with a vegetarian diet was nonsignificant after adjustment for demographic, lifestyle, and clinical characteristics. Several dietary patterns and practices associated with beneficial health effects are significantly associated with longer LTL. However, the magnitude of the association was small, and any clinical relevance is uncertain. [ABSTRACT FROM AUTHOR]

A correction is presented to the article "Cancer in British Vegetarians: Updated Analyses of 4998 Incident Cancers in a Cohort of 32,491 Meat Eaters, 8612 Fish Eaters, 182,298 Vegetarians and 2246 Vegans" which appeared in the 2014 issue of the magazine.

Background: Despite the consistent findings of lower total cancer incidence in vegetarians than in meat-eaters in the UK, the results of studies of colorectal cancer (CRC) risk in British vegetarians have largely been null. This was in contrast to the hypothesis of a decreased risk of CRC in this population due to null intake of red and processed meats and increased intake of fibre. Although the data are inconsistent, it has been suggested that selenium (Se) status may influence CRC risk. Methods: A literature review was performed of studies on CRC risk in vegetarians, Se intakes and status in vegetarians, and changes of Se intakes and status in the UK throughout the follow-up periods of studies on CRC risk in British vegetarians. Results: Vegetarians in the UK and other low-Se areas were found to have low Se intakes and status compared to non-vegetarians. There was some evidence of a reverse J-shaped curve of Se intakes and status in the UK throughout the last three decades. These presumed patterns were followed by the changes in CRC mortality or incidence in British vegetarians during this period. Conclusions: Available data on Se intake and status in British vegetarians, as well as the relationship between their secular changes in the UK and changes in CRC risk in this dietary group, are compatible with the hypothesis that low Se status may contribute to the largely null results of studies of CRC risk in vegetarians in the UK.

Background: Vegetarians and others who do not eat meat have been observed to have lower incidence rates than meat eaters of some chronic diseases, but it is unclear whether this translates into lower mortality. Objective: The purpose of this study was to describe mortality in vegetarians and comparable nonvegetarians in a large United Kingdom cohort. Design: The study involved a pooled analysis of data from 2 prospective studies that included 60,310 persons living in the United Kingdom, comprising 18,431 regular meat eaters (who ate meat ≥5 times/wk on average), 13,039 low (less-frequent) meat eaters, 8516 fish eaters (who ate fish but not meat), and 20,324 vegetarians (including 2228 vegans who did not eat any animal foods). Mortality by diet group for each of 18 common causes of death was estimated with the use of Cox proportional hazards models. Results: There were 5294 deaths before age 90 in >1 million y of follow-up. There was no significant difference in overall (all-cause) mortality between the diet groups: HRs in low meat eaters, fish eaters, and vegetarians compared with regular meat eaters were 0.93 (95% CI: 0.86, 1.00), 0.96 (95% CI: 0.86, 1.06), and 1.02 (95% CI: 0.94, 1.10), respectively; P-heterogeneity of risks = 0.082. There were significant differences in risk compared with regular meat eaters for deaths from circulatory disease [higher in fish eaters (HR: 1.22; 95% CI: 1.02, 1.46)]; malignant cancer [lower in fish eaters (HR: 0.82; 95% CI: 0.70, 0.97)], including pancreatic cancer [lower in low meat eaters and vegetarians (HR: 0.55; 95% CI: 0.36, 0.86 and HR: 0.48; 95% CI: 0.28, 0.82, respectively)] and cancers of the lymphatic/hematopoietic tissue [lower in vegetarians (HR: 0.50; 95% CI: 0.32, 0.79)]; respiratory disease [lower in low meat eaters (HR: 0.70; 95% CI: 0.53, 0.92)]; and all other causes [lower in low meat eaters (HR: 0.74; 95% CI: 0.56, 0.99)]. Further adjustment for body mass index left these associations largely unchanged. Conclusions: United Kingdom--based vegetarians and comparable nonvegetarians have similar all-cause mortality. Differences found for specific causes of death merit further investigation. [ABSTRACT FROM AUTHOR]

Background: Human metabolism is influenced by dietary factors and lifestyle, environmental, and genetic factors; thus, men who exclude some or all animal products from their diet might have different metabolic profiles than meat eaters. Objective: We aimed to investigate differences in concentrations of 118 circulating metabolites, including acylcarnitines, amino acids, biogenic amines, glycerophospholipids, hexose, and sphingolipids related to lipid, protein, and carbohydrate metabolism between male meat eaters, fish eaters, vegetarians, and vegans from the Oxford arm of the European Prospective Investigation into Cancer and Nutrition. Design: In this cross-sectional study, concentrations of metabolites were measured by mass spectrometry in plasma from 379 men categorized according to their diet group. Differences in mean metabolite concentrations across diet groups were tested by using ANOVA, and a false discovery rate-controlling procedure was used to account for multiple testing. Principal component analysis was used to investigate patterns in metabolic profiles. Results: Concentrations of 79% of metabolites differed significantly by diet group. In the vast majority of these cases, vegans had the lowest concentration, whereas meat eaters most often had the highest concentrations of the acylcarnitines, glycerophospholipids, and sphingolipids, and fish eaters or vegetarians most often had the highest concentrations of the amino acids and a biogenic amine. A clear separation between patterns in the metabolic profiles of the 4 diet groups was seen, with vegans being noticeably different from the other groups because of lower concentrations of some glycerophospholipids and sphingolipids. Conclusions: Metabolic profiles in plasma could effectively differentiate between men from different habitual diet groups, especially vegan men compared with men who consume animal products. The difference in metabolic profiles was mainly explained by the lower concentrations of glycerophospholipids and sphingolipids in vegans. [ABSTRACT FROM AUTHOR]

CVD remains the major cause of death for dialysis patients. Dialysis patients have both traditional and nontraditional risk factors, including the retention of advanced glycation end products (AGE). Tissue AGE can be measured by skin autofluorescence (SAF) and are a reliable measurement of chronic exposure. Dietary intake of AGE may be lower in vegetarian patients than in non-vegetarian patients, so we determined whether vegetarian patients had lower SAF than non-vegetarian patients. We measured SAF in 332 adult haemodialysis patients using a UV technique in a standardised manner. Information about patients' demographic data, laboratory results and current medicinal prescriptions was collected retrospectively from the hospital's computerised database. The mean patient age was 65·2 (sd 15·1) years, 64 % were men, 42 % were diabetic, and 66 % were Caucasian. The mean SAF was 3·26 (sd 0·95) arbitrary units (AU), and SAF was lower in vegetarians as compared to non-vegetarians (2·71 (sd 0·6) v. 3·31 (sd 0·97) AU, P= 0·002). SAF was negatively correlated on both univariate (r − 0·17, P= 0·002) and multiple linear regression (β coefficient − 0·39, 95 % CI − 0·7, − 0·07, P= 0·019). SAF, a marker of tissue AGE deposition, was reduced in vegetarian haemodialysis patients after correction for known confounders, which suggests that a vegetarian diet may reduce exposure to preformed dietary AGE. Dietary manipulation could potentially reduce tissue AGE and SAF as well as CVD risk, but further prospective studies are warranted to confirm the present findings. [ABSTRACT FROM PUBLISHER]

The article explores playwright Bernard Shaw's views on health, a subject he frequently discussed in most of his work done during his early years in London, England and mostly focused on vegetarianism, smallpox and other health issues. Topics discussed include Shaw's approach of integrating health issues into theater with his work "The Doctor's Dilemma," his opinion on collective wellness, progressive growth and fitness and Shaw's reformist views on public health.

Background: There is limited evidence with regard to the effect of different sources of protein on appetite during weight loss. Vegetarian and meat-based high-protein diets may have contrasting effects on appetite and biomarkers of protein-induced satiety. Objective: The aim was to assess appetite response to meat or vegetarian high-protein weight-loss (HPWL) diets in obese men to monitor plasma amino acid profile and gut peptide response as potential satiety biomarkers. Design: Twenty obese [body mass index (in kg/m²): 34.8] men participated in a dietary intervention study. After 3 d of a maintenance diet, they were provided in a crossover design with either a vegetarian HPWL (Soy-HPWL) or a meat-based HPWL (Meat-HPWL) diet for 2 wk. Both diets comprised 30% protein, 30% fat, and 40% carbohydrate, provided to measured resting metabolic rate. Body weight and the motivation to eat were measured daily. Plasma satiety biomarkers were collected during a test-meal challenge (5 h) at the end of each diet period. Results: Over the 2 wk, subjects lost, on average, 2.41 and 2.27 kg with consumption of the Soy- and Meat-HPWL diets, respectively [P = 0.352; SE of the difference (SED): 0.1]. ANOVA confirmed that subjectively rated hunger (P = 0.569; SED: 3.8), fullness (P = 0.404; SED: 4.1), desire to eat (P = 0.356; SED: 3.7), preservation of lean body mass (P = 0.334; SED: 0.2), and loss of percentage fat mass (P = 0.179; SED: 0.2) did not differ between the 2 HPWL diets. There were differences in absolute concentrations of ghrelin and peptide YY between the 2 HPWL diets, although the response as net area under the curve was not different. Conclusions: Appetite control and weight loss were similar for both HPWL diets. Gut hormone profile was similar between the diets, which suggests that vegetarian diets can be as effective as meat-based diets for appetite control during weight loss. This trial was registered at www.clinicaltrials.gov as NCT02080325. [ABSTRACT FROM AUTHOR]

Background: Vegetarian diets might affect the risk of cancer. Objective: The objective was to describe cancer incidence in vegetarians and nonvegetarians in a large sample in the United Kingdom. Design: This was a pooled analysis of 2 prospective studies including 61,647 British men and women comprising 32,491 meat eaters, 8612 fish eaters, and 20,544 vegetarians (including 2246 vegans). Cancer incidence was followed through nationwide cancer registries. Cancer risk by vegetarian status was estimated by using multivariate Cox proportional hazards models. Results: After an average follow-up of 14.9 y, there were 4998 incident cancers: 3275 in meat eaters (10.1%), 520 in fish eaters (6.0%), and 1203 in vegetarians (5.9%). There was significant heterogeneity between dietary groups in risks of the following cancers: stomach cancer [RRs (95% CIs) compared with meat eaters: 0.62 (0.27, 1.43) in fish eaters and 0.37 (0.19, 0.69) in vegetarians; P-heterogeneity = 0.006], colorectal cancer [RRs (95% CIs): 0.66 (0.48, 0.92) in fish eaters and 1.03 (0.84, 1.26) in vegetarians; P-heterogeneity = 0.033], cancers of the lymphatic and hematopoietic tissue [RRs (95% CIs): 0.96 (0.70, 1.32) in fish eaters and 0.64 (0.49, 0.84) in vegetarians; P-heterogeneity = 0.005], multiple myeloma [RRs (95% CIs): 0.77 (0.34, 1.76) in fish eaters and 0.23 (0.09, 0.59) in vegetarians; P-heterogeneity = 0.010], and all sites combined [RRs (95% CIs): 0.88 (0.80, 0.97) in fish eaters and 0.88 (0.82, 0.95) in vegetarians; P-heterogeneity = 0.0007]. Conclusion: In this British population, the risk of some cancers is lower in fish eaters and vegetarians than in meat eaters. [ABSTRACT FROM AUTHOR]

This study explores the importance of food and the negotiation of kosher laws in the context of strategies to maintain an individual and collective Jewish identity among a British Reform Jewish community in a non-metropolitan area. Based on interviews with active members of the local synagogue, it explores the challenges to maintaining Jewish life in a small, disparate community remote from any major Jewish settlement. In the interview data, food emerges as a major point of reference for defining identity and for positioning members of the community in relation to religious traditions. Food observance further serves as a means of defining boundaries within as well as outside the community. This discussion raises several important issues: the place of religious observance in modern societies, the question of membership and boundaries of communities, the diversity of contemporary Jewish Reform observance and, finally, the specific role of food and foodways in negotiating these challenges.

Maternal body weight and diet quality, even pre-pregnancy, can affect the uterine environment, birth weight and the baby's subsequent health into adulthood. This article briefly discusses dietary and nutritional advice for women around pregnancy. However, some groups of women may be particularly vulnerable to suboptimal nutrition and therefore may require more targeted diet and nutrition advice. Specific nutrient issues among several vulnerable groups are discussed in this article. [ABSTRACT FROM AUTHOR]

The article discusses importance of good nutrition in children. It highlights the nutrition needed by children and adolescents which are high in relation to their size due to their demands for growth. It also explores the results of the National Diet and Nutrition Surveys (NDNS) wherein data on the eating patterns of people living in private households in Great Britain is provided.

This article explores the complex inter-relationship between evangelicalism and the formation of an organised vegetarian movement in Britain in the period 1847-1860. As well as adding insight into existing historical research into the diet, I will comment on the potential of evangelicalism's influence to reach into various areas of society, a claim that has often been contested in the existing historiography. I will explore the manner by which religious belief interacted with medico-scientific views pertaining to diet; and how it penetrated views on the role of diet to family life. [ABSTRACT FROM AUTHOR]

Little is known about the role of maternal nutrition in the development of hypospadias, which is the most common urogenital congenital anomaly. This study investigated the relationship between maternal nutrition and the risk of hypospadias, particularly focusing on maternal food patterns. We compared 471 hypospadias cases with 490 controls in the United Kingdom. A questionnaire including information on life style, occupation, usual maternal diet and dietary supplements was administered using telephone interviews. Cases and controls were compared for individual food item intake and food patterns derived by cluster analysis. Multivariable logistic regression analysis adjusted for income, maternal age, low birthweight, smoking and folic acid supplement use was used to assess the relationship between maternal nutrition and hypospadias. Three food patterns were created with the labels 'health conscious', 'mixed' and 'non-health conscious'. 'Non-health conscious' subjects (low frequency of consumption of yoghurt, cheese, eggs, fruit and vegetables, fish, beans and pulses, olive oil and organic food) had a higher risk of hypospadias (odds ratio 1.54; 95% confidence interval 1.06, 2.26) compared with 'health conscious' subjects (high frequency of consumption of fresh fruit and vegetables, dried fruit, fresh or frozen fish, beans, pulses, soya products, olive oil and organic food), after adjustment for potential confounders. Intakes of individual foods were not strongly associated with hypospadias. We could not exclude the possibility of residual confounding, and this needs to be further investigated. We found an association between food pattern and hypospadias, with those with less health conscious food patterns having a higher risk. Further study is needed to confirm this association.

Dorothy Richardson is regarded as one of the epitomes of female modernism and her magnum opus, Pilgrimage, is celebrated for its depiction of 'feminine consciousness'. What has not been explored, however, is Richardson's interest in the possibilities of Fabian Socialism, and specifically her belief in land reform. This is, in fact, a significant aspect of her egalitarian vision and one that Richardson's protagonist, Miriam Henderson, never abandons. Richardson's literary and, for a time, ideological contemporaries were George Bernard Shaw and H.G. Wells and Pilgrimage engages sporadically with their political ideals. This thinking underpins Richardson's airing of utopian values, concerns about economic migration and her interest in vegetarianism at the beginning of the twentieth century. By setting Pilgrimage in this Fabian context, aspects of the text are transformed into a political critique centred on furthering the idea of a spatially re-arranged future, whilst Richardson's use of irony questions the adequacy of the Fabian response to a series of entrenched social problems.

Background: Few prospective studies have examined cancer incidence among vegetarians.Methods: We studied 61,566 British men and women, comprising 32,403 meat eaters, 8562 non-meat eaters who did eat fish ('fish eaters') and 20,601 vegetarians. After an average follow-up of 12.2 years, there were 3350 incident cancers of which 2204 were among meat eaters, 317 among fish eaters and 829 among vegetarians. Relative risks (RRs) were estimated by Cox regression, stratified by sex and recruitment protocol and adjusted for age, smoking, alcohol, body mass index, physical activity level and, for women only, parity and oral contraceptive use.Results: There was significant heterogeneity in cancer risk between groups for the following four cancer sites: stomach cancer, RRs (compared with meat eaters) of 0.29 (95% CI: 0.07-1.20) in fish eaters and 0.36 (0.16-0.78) in vegetarians, P for heterogeneity=0.007; ovarian cancer, RRs of 0.37 (0.18-0.77) in fish eaters and 0.69 (0.45-1.07) in vegetarians, P for heterogeneity=0.007; bladder cancer, RRs of 0.81 (0.36-1.81) in fish eaters and 0.47 (0.25-0.89) in vegetarians, P for heterogeneity=0.05; and cancers of the lymphatic and haematopoietic tissues, RRs of 0.85 (0.56-1.29) in fish eaters and 0.55 (0.39-0.78) in vegetarians, P for heterogeneity=0.002. The RRs for all malignant neoplasms were 0.82 (0.73-0.93) in fish eaters and 0.88 (0.81-0.96) in vegetarians (P for heterogeneity=0.001).Conclusion: The incidence of some cancers may be lower in fish eaters and vegetarians than in meat eaters.

Perceived social norms refer to beliefs that people hold about what other people do (descriptive norms) and approve of (injunctive norms), and are associated with food intake. However, less is known about whether perceived social norms are associated with meat and plant-based meal intake. Using a cross-sectional survey design 136 participants (aged 19-66 years, mean age = 39.63, SD = 12.85 years, mean BMI = 25.77, SD = 5.30, 80.9 % female, 77.9 % omnivores, 22.1 % flexitarians) answered questions about how frequently they consumed meat and plant-based meals, and how frequently they perceived people in their social environment to consume (perceived descriptive norms), and approve of consuming (perceived injunctive norms) meat and plant-based meals. Perceived descriptive and injunctive norms were positively associated with participants' frequency of meat intake: participants ate meat more frequently when they perceived their significant other to frequently eat meat (descriptive norm), and when they perceived their significant other and friends to approve of (injunctive norm) frequently eating meat. Perceived descriptive norms were positively associated, but injunctive norms were negatively associated with participants' frequency of plant-based meal intake: participants ate plant-based meals more frequently when they perceived their extended family, friends, and significant other to frequently eat plant-based meals. However, participants ate plant-based meals more frequently when they perceived their extended family to approve of less frequent plant-based meal intake. These results suggest that different social groups may be important for meat and plant-based meal intake, with significant others and friends appearing to be important reference points for both food types. Further research examining the contexts in which the different social groups influence eating behaviour would be of value. [ABSTRACT FROM AUTHOR]

Objective To examine the relation between IQ in childhood and vegetarianism in adulthood. Design Prospective cohort study in which IQ was assessed by tests of mental ability at age 10 years and vegetarianism by self-report at age 30 years. Setting Great Britain. Participants 8170 men and women aged 30 years participating in the 1970 British cohort study, a national birth cohort. Main outcome measures Self-reported vegetarianism and type of diet followed. Results 366 (4.5%) participants said they were vegetarian, although 123 (33.6%) admitted eating fish or chicken. Vegetarians were more likely to be female, to be of higher social class (both in childhood and currently), and to have attained higher academic or vocational qualifications, although these socioeconomic advantages were not reflected in their income. Higher IQ at age 10 years was associated with an increased likelihood of being vegetarian at age 30 (odds ratio for one standard deviation increase in childhood IQ score 1.38, 95% confidence interval 1.24 to 1.53). IQ remained a statistically significant predictor of being vegetarian as an adult after adjustment for social class (both in childhood and currently), academic or vocational qualifications, and sex (1.20,1.06 to 1.36). Exclusion of those who said they were vegetarian but ate fish or chicken had little effect on the strength of this association. Conclusion Higher scores for IQ in childhood are associated with an increased likelihood of being a vegetarian as an adult. [ABSTRACT FROM AUTHOR]
