Thou Shall Not Kill: Vegetarianism in the Christian Faith

Biblical justifications for a vegetarian diet seem to meet with much adversity within mainstream American culture. Texts suggesting that people were intended to be vegetarians can be found in the Bible. However, this interpretation of Biblical texts has not been widely accepted by Protestant Christianity. This research attempts to identifY social and religious characteristics of people who are vegetarian. Fundamentalism, denomination, belief in the inerrancy of the Bible, and strength of belief in Christianity are examined as factors related to supporting vegetarianism. The General Social Survey's data from 1993 and 1994 were used in this study. The data were analyzed using frequencies, means, cross tabulations. correlations, and regressions. The sample was 57% female and 87% white, the mean age was 46 and the average level of education was 13 years. The study found that, among the independent variables. belief in animal rights, rather than any specific religious views, had the strongest influence on vegetarianism.

Manipolazione del metabolismo degli xenobiotici da frutta convenzionale ed attività chemiopreventiva

A reduced cancer risk associated with fruit and vegetable phytochemicals initially dictated chemopreventive approaches focused on specific green variety consumption or even single nutrient supplementations. However, these strategies not only failed to provide any health benefits but gave rise to detrimental effects. In parallel, public-health chemoprevention programmes were developed in the USA and Europe to increase whole vegetable consumption. Among these, the National Cancer Institute (NCI) sponsored plan “5 to 9 a day for a better health” was one of the most popular. This campaign promoted wide food choice through the consumption of at least 5 to 9 servings a day of colourful fruits and vegetables. In this study the effects of the diet suggested by NCI on transcription, translation and catalytic activity of both xenobiotic metabolizing (XME) and antioxidant enzymes were studied in the animal model. In fact, the boost of both antioxidant defences and “good” phase-II together with down-regulation of “bad” phase-I XMEs is still considered one of the most widely-used strategies of cancer control. Six male Sprague Dawley rats for each treatment group were used. According to the Italian Society of Human Nutrition, a serving of fruit, vegetables and leafy greens corresponds to 150, 250 and 50 g, respectively, in a 70 kg man. Proportionally, rats received one or five servings of lyophilized onion, tomato, peach, black grape or lettuce – for white, red, yellow, violet or green diet, respectively - or five servings of each green (“5 a day” diet) by oral gavage daily for 10 consecutive days. Liver subcellular fractions were tested for various cytochrome P450 (CYP) linked-monooxygenases, phase-II supported XMEs such as glutathione S-transferase (GST) and UDP-glucuronosyl transferase (UDPGT) as well as for some antioxidant enzymes. Hepatic transcriptional and translational effects were evaluated by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis, respectively. dROMs test was used to measure plasmatic oxidative stress. Routine haematochemical parameters were also monitored. While the five servings administration didn’t significantly vary XME catalytic activity, the lower dose caused a complex pattern of CYP inactivation with lettuce exerting particularly strong effects (a loss of up to 43% and 45% for CYP content and CYP2B1/2-linked XME, respectively; P<0.01). “5 a day” supplementation produced the most pronounced modulations (a loss of up to 60% for CYP2E1-linked XME and a reduction of CYP content of 54%; P<0.01). Testosterone hydroxylase activity confirmed these results. RT-PCR and Western blot analysis revealed that the “5 a day” diet XMEs inactivations were a result of both a transcriptional and a translational effect while lettuce didn’t exert such effects. All administrations brought out none or fewer modulation of phase-II supported XMEs. Apart from “5 a day” supplementation and the single serving of lettuce, which strongly induced DT- diaphorase (an increase of up to 141 and 171%, respectively; P<0.01), antioxidant enzymes were not significantly changed. RT-PCR analysis confirmed DT-diaphorase induction brought about by the administration of both “5 a day” diet and a single serving of lettuce. Furthermore, it unmasked a similar result for heme-oxygenase. dROMs test provided insight into a condition of high systemic oxidative stress as a consequence of animal diet supplementation with “5 a day” diet and a single serving of lettuce (an increase of up to 600% and 900%, respectively; P<0.01). Haematochemical parameters were mildly affected by such dietary manipulations. According to the classical chemopreventive theory, these results could be of particular relevance. In fact, even if antioxidant enzymes were only mildly affected, the phase-I inactivating ability of these vegetables would be a worthy strategy to cancer control. However, the recorded systemic considerable amount of reactive oxygen species and the complexity of these enzymes and their functions suggest caution in the widespread use of vegan/vegetarian diets as human chemopreventive strategies. In fact, recent literature rather suggests that only diets rich in fruits and vegetables and poor in certain types of fat, together with moderate caloric intake, could be associated with reduced cancer risk.

DIETARY RELATIONSHIPS TO FATAL BREAST CANCER AMONG SEVENTH-DAY ADVENTISTS

Laboratory experiments in animals, correlational and migrant studies in humans suggest a role for diet in the etiology of breast cancer. Data gathered from individuals via case-control studies are less consistent. Seventh-day Adventist women experience lower mortality from breast cancer than comparable U.S. populations and this decrease is thought to be, at least in part, related to dietary practices (half are vegetarian). In 1960, 25,000 California Seventh-day Adventists completed a questionnaire which included a 21 item food frequency section. Cancer mortality in this population was monitored between 1960 and 1980 and the relationship of high fat food intake and fatal breast cancer was evaluated. Although established risk factors for breast cancer were observed in this population (e.g. age at menarche, age at first pregnancy, age at menopause and obesity) consumption of high fat foods were not observed to exert a strong influence on fatal breast cancer risk. Odds ratios (O.R.) for fatal breast cancer among non-vegetarians was 1.2. Increasing meat consumption bore little relation to risk; O.R. = 1.0, 1.2, 1.1 for consumption categories of none/occasional, 1-3 days/week and 4+ days/week respectively. Nor did the consumption of other high fat foods of animal origin (e.g. butter, cheese, milk, eggs) show any relationship to risk. These results remained unchanged after simultaneously controlling for the effect of other, potentially confounding variables (menstrual characteristics, obesity) via logistic regression analysis. ^

Análise da microbiota intestinal em adultos com hábitos alimentares distintos e de associações com a inflamação e resistência à insulina

Introdução: A microbiota intestinal possui grande diversidade de bactérias, predominantemente dos filos Bacteroidetes e Firmicutes, com múltiplas funções. A alimentação pode alterar sua composição e função. Alto teor de gordura saturada altera a permeabilidade intestinal, eleva os lipopolissacarídeos e predispõe à inflamação subclínica crônica. Dieta rica em fibras, como a vegetariana, induz elevação de ácidos graxos de cadeia curta e benefícios metabólicos. Objetivos: Para analisar a composição da microbiota intestinal de adventistas com diferentes hábitos alimentares e associá-los à inflamação subclínica e resistência à insulina, esta tese incluiu: 1) revisão dos mecanismos que associam a alimentação à microbiota intestinal e ao risco cardiometabólico; 2) verificação da composição da microbiota intestinal segundo diferentes hábitos alimentares e de associações com biomarcadores de doenças cardiometabólicas; 3) avaliação da associação entre a abundância de Akkermansia muciniphila e o metabolismo da glicose; 4) análise da presença de enterótipos e de associações com características clínicas. Métodos: Este estudo transversal incluiu 295 adventistas estratificados segundo hábitos alimentares (vegetariano estrito, ovo-lacto-vegetariano e onívoro). Foram avaliadas associações com dados clínicos, bioquímicos e inflamatórios. O perfil da microbiota foi obtido por sequenciamento do gene 16S rRNA (Illumina® Miseq). Resultados: 1) Há evidências de que as relações entre dieta, inflamação, resistência à insulina e risco cardiometabólico são em parte mediadas pela composição da microbiota intestinal. 2) Vegetarianos apresentaram melhor perfil clínico quando comparados aos onívoros. Confirmou-se maior abundância de Firmicutes e Bacteroidetes, que não diferiram segundo a adiposidade corporal. Entretanto, vegetarianos estritos apresentaram mais Bacteroidetes, menos Firmicutes e maior abundância do gênero Prevotella quando comparados aos outros dois grupos de hábitos alimentares. Entre os ovo-lactovegetarianos verificou-se maior proporção de Firmicutes especialmente do gênero Faecalibacterium. Nos onívoros, houve super-representação do filo Proteobacteria (Succinivibrio e Halomonas) comparados aos vegetarianos. 3) Indivíduos normoglicêmicos apresentaram maior abundância de Akkermansia muciniphila que aqueles com glicemia alterada. A abundância desta bactéria correlacionou-se inversamente à glicemia e hemoglobina glicosilada. 4) Foram identificados três enterótipos (Bacteroides, Prevotella e Ruminococcaceae), similares àqueles previamente descritos. As concentrações de LDL-C foram menores no enterótipo 2, no qual houve maior frequência de vegetarianos estritos. Discussão: 1) Conhecimentos sobre participação da microbiota na fisiopatologia de doenças poderão reverter em estratégias para manipulá-la para promover saúde. 2) Apoia-se a hipótese de que hábitos alimentares se associam favorável ou desfavoravelmente a características metabólicas e inflamatórias do hospedeiro via alterações na composição da microbiota intestinal. Sugerimos que a exposição a alimentos de origem animal possa impactar negativamente nas proporções de comunidades bacterianas. 3) Sugerimos que a abundância da Akkermansia muciniphila possa participar do metabolismo da glicose. 4) Reforçamos que a existência de três enterótipos não deva ser específica de certas populações/continentes. Apesar de desconhecido o significado biológico destes agrupamentos, as correlações com o perfil lipídico podem sugerir sua utilidade na avaliação do risco cardiometabólico. Conclusões: Nossos achados fortalecem a ideia de que a composição da microbiota intestinal se altera mediante diferentes hábitos alimentares, que, por sua vez, estão associados a alterações nos perfis metabólicos e inflamatórios. Estudos prospectivos deverão investigar o potencial da dieta na prevenção de distúrbios cardiometabólicos mediados pela microbiota.

Not being what you claim to be: impostors as sources of group threat

We examine the notion of impostors within groups, defined in this paper as people who make public claims to an identity while disguising their failure to fulfil key criteria for group membership. In Experiment 1, vegetarians showed heightened levels of negative affect toward vegetarians who ate meat occasionally compared to an authentic vegetarian. In contrast, non-vegetarians saw the impostor to be marginally more likeable than the authentic vegetarian. In Experiments 2 and 3, participants evaluated only a vegetarian who ate meat. Evaluations of the target were influenced by group attachment, such that participants who identified strongly as vegetarians downgraded the target more strongly and experienced more negative affect than did moderate identifiers and non-vegetarians. Participants were also sensitive to the size of the gulf between the target's claims for identity and their behaviour. Thus, targets who made public claims to being a vegetarian but ate meat were evaluated more negatively than were people who kept their claims for identity private (Experiment 2). Similarly, targets who tried to keep their deviant behaviour secret were evaluated more negatively than were people who openly admitted their deviant behaviour (Experiment 3). The reasons why impostors might threaten the integrity of group identities are discussed. Copyright (C) 2003 John Wiley Sons, Ltd.

When differences matter: Intergroup distinctiveness and the evaluation of impostors

The present study examined the effect of intergroup distinctiveness and group membership on evaluations of impostors. We predicted that ingroup members would be harsher than outgroup members on an impostor and that perceptions of intergroup distinctiveness would further moderate these evaluations. Specifically, we tested the social identity theory prediction that low intergroup distinctiveness would lead to greater derogation of the impostor (the 'reactive distinctiveness' hypothesis) against the self-categorization hypothesis that high intergroup distinctiveness would instigate more derogation of an impostor (the 'reflective distinctiveness' hypothesis). In this study, vegetarians (ingroup members) and meat eaters (outgroup members) were presented with a target claiming to be vegetarian, but caught indulging in a meat dish. We found that ingroup members derogated the impostor more and felt less pleased about discovering the impostor behaviour than did outgroup members. In line with the reflective distinctiveness hypothesis, the heightened derogation displayed by ingroup members only emerged when intergroup distinctiveness was high, an effect that was mediated by ratings of group identification. The discussion focuses on the different responses intergroup distinctiveness may evoke. Copyright (c) 2005 John Wiley & Sons, Ltd.

Vegetarians: A Typology for Foodservice Menu Development

There is currently a lack of research about the needs of vegetarians, from a practitioner or academic perspective. This paper contributes to filling this research gap, by discussing the needs of vegetarians who dine out and their current difficulties in participating in the dining experience, in the present context. Specifically, it is argued that the typology of vegetarians presented in this paper, based on their motivations to adopt the chosen diet, might prove useful for restaurants in order to understand the vegetarian guest and develop menu items and services that will better cater to their needs. Recommendations for practitioners and future research areas are presented.

The cost of a minimum essential food basket in the Republic of Ireland: Study for six household types.

A Minimum Essential Standard of Living (MESL) is derived from a negotiated consensus on what people believe is a minimum standard. It is a standard of living that meets an individual’s or a household’s physical, psychological and social needs. This is calculated by identifying the goods and services required by different household types in order to meet their needs. While an MESL is based on needs, not wants, it is a standard of living below which nobody should be expected to live. This report focuses on food, one of the 16 elements of the Minimum Essential Standard of Living (MESL) data. It is based on a methodology called Consensual Budget Standards (CBS). The report is presented in the context of increasing concerns about the issue of food poverty in the Republic of Ireland (ROI) and an increase in the number of people reporting that they do not have enough money to buy food. Recent data from The Organisation for Economic Co-operation and Development (OECD) have shown that the number of people believing they cannot afford food doubled from 4.2% in 2008 to 9% in 2014. Data from Eurostat show that in 2013, food and non-alcoholic beverage prices in Ireland were 17% higher than the EU average. Moreover, research by Carney and Maitre, using data from the Survey on Income and Living Conditions (SILC), found that one in ten people are living in food poverty in Ireland. Food poverty is defined as the inability to have an adequate and nutritious diet due to issues of affordability and access to food. This has related effects on health, culture and social participation. The 2013 data from the Survey on Income and Living Conditions (SILC) show that 1.4 million people, almost 31% of the population, suffer from deprivation. This means that they are unable to afford two items from a list of 11 very basic items (of which one is not being able to eat a meal with meat, chicken, fish or a vegetarian equivalent every second day). The highest levels of deprivation are experienced by lone parents (63%), unemployed people (55%) and people not at work because of illness or disability (53%). The experience of the Vincentian Partnership for Social Justice (VPSJ) is that expenditure on food tends to be one of the least important considerations when households are dealing with competing demands on an inadequate income.

An Unexpected Cause of Marked Weight Loss Associated with Vomiting in an Adult Man: Gastric Phytobeozar

Objectives: We present the case of an edentulous 47-year-old farmer referred to our Department of Internal Medicine because of postprandial vomiting, hyporexia, asthenia and weight loss. He ate a mostly vegetarian diet. Materials and methods: An oesophagogastroduodenoscopy revealed the presence of a phytobezoar at the level of the fundus and body of the stomach. Endoscopic fragmentation and removal of the phytobezoar were unsuccessful and the patient had to undergo open surgery. Results: Recovery was uneventful and free of complications. Conclusion: Phytobezoars should be taken into account in the differential diagnosis of unexplained vomiting and weight loss.

Factors Affecting the Body Mass Index in Adolescents in Portuguese Schools

The prevalence of overweight and obesity among children is increasing; hence, it was aimed to assess the Body Mass Index (BMI) in school children aged from 10 to 18 years for girls and to 17 for boys, as well as to identify the factors influencing BMI. This study included 742 students who answered a questionnaire previously approved for application in schools. The results showed some sociodemographic factors associated with BMI classes: age, school year, practicing high competition sport, being federate in a sport or having a vegetarian diet. The educational factors associated with BMI classes included only seminars given at school by a nutritionist. Behavioural factors significantly associated with BMI included: learning in classes, playing in the open air, reading books or use of internet. As conclusion, the results demonstrated that several factors affect BMI, and hence some actions could be taken in order to change them so as to reduce the prevalence of overweight, namely reinforcing the role of school and a more active participation of nutritionists in the education of the adolescents.
