Lifestyle-related disease in Crohn’s disease: Relapse prevention by a semi-vegetarian diet

AIM: To investigate whether semi-vegetarian diet (SVD) has a preventive effect against relapse of Crohn’s disease (CD) in patients who have achieved remission,who are a high-risk group for relapse.METHODS: A prospective,single center,2-year clinical trial was conducted.Twenty-two adult CD patients who achieved clinical remission either medically (n = 17) or surgically (n = 5) and consumed an SVD during hospitalization were advised to continue with an SVD and avoid known high-risk foods for inflammatory bowel disease.The primary endpoint was clinical relapse defi ned as the appearance of active symptoms of CD.Kaplan-Meier survival analysis was used to calculate the cumulative proportion of patients who had a relapse.A 2-year analysis of relapse rates of patients who followed an SVD and those who did not (an omnivorous diet group) was undertaken.RESULTS: SVD was continued by 16 patients (compliance 73%).Remission was maintained in 15 of 16 patients (94%) in the SVD group vs two of six (33%)in the omnivorous group.Remission rate with SVD was 100% at 1 year and 92% at 2 years.SVD showed signif icant prevention in the time to relapse compared to that in the omnivorous group (P = 0.0003,log rank test).The concentration of C-reactive protein was normal at the f inal visit in more than half of the patients in remission who were taking an SVD,who maintained remission during the study (9/15;60%),who terminated follow-up (8/12;67%),and who completed 2 years follow-up (7/10;70%).There was no untoward effect of SVD.CONCLUSION: SVD was highly effective in preventing relapse in CD.

Cultured meat in western media: The disproportionate coverage of vegetarian reactions, demographic realities, and implications for cultured meat marketing

This paper examines the media coverage of the 2013 London cultured meat tasting event, particularly in the United States, Canada, and the United Kingdom. Using major news outlets, prominent magazines covering food and science issues, and advocacy websites concerning meat consumption, the paper characterizes the overall emphases of the coverage, the tenor of the coverage, and compares the media portrayal of the important issues to the demographic and psychological realities of the actual consumer market into which cultured meat will compete. In particular, the paper argues that Western media gives a distorted picture of what obstacles are in the path of cultured meat acceptance, especially by overemphasizing and overrepresenting the importance of the reception of cultured meat among vegetarians. Promoters of cultured meat should recognize the skewed impression that this media coverage provides and pay attention to the demographic data that suggests strict vegetarians are a demographically negligible group. Resources for promoting cultured meat should focus on the empirical demographics of the consumer market and the empirical psychology of mainstream consumers.

Risks of iron deficiency among vegetarian college women

Iron deficiency anemia is the most common nutritional deficiency disease worldwide and poses a major threat in women of child-bearing age and those who follow a vegetarian diet. The objective of this study was to ascertain whether differences exist in iron status markers between female university students following a vegetarian and non-vegetarian diet. This study took a cross sectional analysis of 39 female students at California Polytechnic State University (Cal Poly State University) in San Luis Obispo, CA between the ages of 18 and 22. Of the participants, 19 followed a vegetarian diet and 20 followed a nonvegetarian diet. Characteristic, demographic, and anthropometric data were collected and analyzed. The results showed no significant difference in iron intake between the two groups. However, nearly 66% of vegetarians and 65% of non-vegetarians failed to meet the Recommended Daily Allowance for iron. No significant difference was found for serum iron, serum ferritin, transfer-rin saturation, and total iron binding capacity between subjects. Serum ferritin tended to be lower for vegetarians compared to non-vegetarians. Both vegetarians and non-vegetarians were in stage IV negative iron balance, with more vegetarians tending to be in stage IV negative iron balance than non-vegetarians. Thus, female college students, irrespective of their meat intake, may be at higher risk of developing negative iron balance and should be educated about iron deficiency anemia and the prevention of iron depletion.

Effects of vegetarian diet-associated nutrients on gut microbiota and intestinal physiology

People are increasingly aware of the role of vegetarian diets in modulating human gut microbial abundance and intestinal physiology.A plant-based diet is thought to benefit host health by contributing to establish a diverse and stable microbiome.In addition,microbe-derived metabolites of specific nutrients known to be abundant in vegetarian diets(such as indigestible carbohydrates,arginine,and others) are important to promote effective intestinal immune responses,maintain intestinal barrier function,and protect against pathogens.This review explores the characteristics of the gut microbiome formed by vegetarian diets and the effects of diet-associated nutrients on intestinal microbial abundance.The interactions between the microbe-derived metabolites of vegetarian diet-associated nutrients and intestinal physiology are also discussed.

Preparation of Dried Vegetarian Soup Supplemented with Some Legumes

The present work was aimed to prepare dried vegetarian soup supplemented with some legumes. Potatoes, hull-less barley flour, carrot, tomatoes, onion, garlic, salt, black pepper, coriander and cumin (served as F1) were used in combination with lentil, green pea and chickpea to formulate F2, F3, and F4, respectively. Chemical, physical, rheological and sensory evaluation was performed. The results indicated that supplementation with legumes significantly enhanced the nutritional characteristics, where the dried vegetarian soup mixtures had reasonable amounts of the required nutrients particularly, protein, carbohydrates, fats, Fe and Zn with good in vitro protein digestibility and mineral availability. Moisture content and water activity predicted the extended shelf-life and stability of the dried soup mixtures. The four resultant soup samples F1, F2, F3 and F4 had a noticeable viscosity pattern characterized by a non-Newtonian pseudoplastic flow behavior. Supplementation with legumes significantly (p ≤ 0.05) affects taste, color, flavor attributes and overall acceptability of the resultant soup samples. But, it had no significant effect on thickness and appearance. The results clearly demonstrated the usefulness of supplementing the dried vegetarian soup mixtures with legumes to enhance nutritional and technological quality of the resultant soup and lentil was the most valuable addition with the highest acceptability.

Is Vegetarianism a Solution for Obesity and NCDs? A Review

Purpose of Review: Obesity is defined as an abnormal fat accumulation associated with disease development risk. The prevalence of obesity and non-communicable diseases (NCDs) continues to increase at a concerning pace. The modern lifestyle requires people to rely on processed foods because of their efficiency and low-cost, which are associated with obesity and NCDs. Vegetarian diet refers to the exclusion of meat, fish, seafood and can also exclude animal products such as dairy and eggs. Therefore, the purpose of this review is to explore vegetarianism as a potential solution for obesity and the development of non-communicable diseases. Recent Findings: Meat intake is also related to unhealthy food groups consumption, contributing to overall poor diet quality. In contrast, vegetarian diets are associated with higher satiety, resulting in less food intake, favoring weight reduction. Lowering the prevalence of NCDs should be a priority, and nutritional interventions are pivotal to accomplish this goal. Summary: Vegetarian diets are associated with weight loss due to: fiber content, lower caloric density, microbiota regulation, and the release of gastrointestinal appetite-regulating hormones. Plant-based eating patterns have demonstrated an overall healthier diet and can be a potential solution for obesity and NCDs’ development.

Vegetarian Diets in Children—Some Thoughts on Restricted Diets and Allergy

Vegetarianism is a common diet worldwide. For a large proportion of people, meat or fish is not available at all or not regularly as a meal. But also in the industrialised countries, vegetarian nutrition is becoming more and more popular for various reasons. Many vegetarian parents also want a suitable diet for their children. But are restrictive diets beneficial or potentially harmful in certain situations, such as a predisposition to severe atopy? Are vegetarian diets equally suitable for pregnant women, nursing mothers, infants, children, and adolescents? What critical nutrients should parents, children, pediatricians, and nutritionists pay particular attention to? This article is focused on questions like these and discusses scientifically based concepts of nutrition. Main findings are that exposure to a variety of food antigens during early life may play a role in the development of healthy eating habits and that restrictive diets have not been found in studies to prevent allergic disease.

Effect of Frying-Cooking on Nutritional and Bioactive Compounds of Innovative Ovo-Vegetarian Diets

Vegetarian diets are becoming increasingly popular as meat prices as well as health concerns rise. Many people are cutting down or cutting out meat in favor of a full vegetarian diet. In present study, the applicability of different vegetables for producing ready-to-use and ready-to-eat chickpea-based ovo-vegetarian diets (OVDs) was investigated. Herein, six different vegetables (cauliflower, taro, green zucchini, pea, bean and spinach) were formulated with 25% chickpea and additional edible ingredients to produce ready-to-use OVDs. Subsequently, chemical composition, minerals content, bioactive compounds and antioxidant activity of those OVDs were investigated. However, ready-to-eat OVDs were organoleptically evaluated after frying as common cooking method. Results of composite analysis indicated 67.73% to 73.17%, 23.20% to 37.12%, 1.86% to 2.63%, 7.63% to 9.53%, 9.06% to 9.82% and 39.24% to 55.28% for moisture, crude protein, lipids, ash, fiber, and carbohydrates contents in ready-to-use OVDs, respectively. After frying, lipid content was increased in fried diets which changed the chemical composition and caloric value. Significant differences (p < 0.05) were found between macro- and micro-nutrients content of ready- to-use and ready-to-eat OVDs. The ready-to-use OVDs exhibit appropriate content of ascorbic acid, chlorophylls, carotenoids, flavonoids, and flavonols which basically depends on their ingredients. Frying process dramatically affected the ascorbic acid, chlorophylls, flavonoids, flavonols, and carotenoids contents. High organoleptic acceptability of ready-to-eat OVDs was recorded to confirm theconsumer attractiveness further. In conclusion, the possibility of producing healthy ready-to-eatand ready-to-use OVDs incorporated with common consumed vegetables could provide a promising approach for improving human health and dietary pattern as well as for selecting the optimum processing conditions for innovative OVDs.

A Brief Research of Vegetarianism in Religious Cultures Between the West and China

Vegetarian is a kind of dietary mode, mainly including plant foods. The vegetarian diet has gradually become a core cultural phenomenon that is deeply rooted in China and the West, which is also closely related to many other factors, especially religions.Practicing vegetarianism in Taoism originates from the pursuit of the unity of man and nature.ln Buddhist, it is profoundly influenced by karma, cleat＂ discipline rules, and six major parts of its reincarnation. While in Christianity, it is affected by the idea of ＂the equality of all creatures＂ and holds the view that everything is created by God, and belongs to God. This paper first discusses the religious beliefs and doctrines of various religions, and then studies their causes and impact on modern society. The aim of this paper is to call on people＇s reverence for life, respect for the natural environment, and the creation of harmonious relationship between man and nature, as well as human beings themselves.

Effects of a shift from a mixed diet to a lacto-vegetarian diet on some coronary heart disease risk markers

Background: There is convincing evidence that vegetarians have lower incidence of coronary heart disease, but there is a debate as to why this is the case. Objective: The aim of the study was to investigate whether a shift from a mixed diet to a lacto-vegetarian diet would lead to a decrease in risk for coronary heart diseases indicated by surrogate markers. Design: Twenty volunteers participated in the study (4 men and 16 women, mean age 44 years, range 27 - 61) from a town in western Sweden. Clinical examinations were performed, blood samples were drawn and dietary survey, i.e. repeated 24-h recalls were carried out before (0 months) and 3, 6 and 12 months after the change from a mixed diet to a lacto-vegetarian diet. A dietician educated the volunteers with regard to the vegetarian dietary regimen, organized and taught the vegetarian cooking courses. Results: The dietary shift lead to an increase in the intake of total carbohydrates and fibre and a decrease in fat, protein and sucrose. The coronary heart disease risk markers body weight, body mass index, systolic and diastolic blood pressure, total cholesterol and low-density lipoptrotein cholesterol decreased significantly. Conclusions: There was a decrease in disease risk markers even though the ratio polyunsaturated to saturated fatty acids was unchanged. The main finding in this study is that there was a weight loss, sustained for one year, without any recommendation to decrease the energy intake or any focus on weight reduction.

Vegetarian diets,circulating miRNA expression and healthspan in subjects living in the Blue Zone

A long-term vegetarian diet plays a role in the longevity and maintenance of the healthspan,but the underlying mechanisms for these observations are largely unknown.Particularly,it is not known whether a longterm vegetarian dietary pattern may affect the circulating miRNA expression in such a way as to modulate the healthspan.The Adventist Health Study-2(AHS-2)cohort includes a large number of older adults who primarily follow vegetarian dietary patterns and reside in Loma Linda,California,one of five“Blue Zones”in the world in which a higher proportion of the population enjoys a longer than average lifespan.We performedmiRNA-seq in 96 subjects selected from the AHS-2 cohort with different dietary patterns.We identified several differentially expressed miRNAs between vegetarians and non-vegetarians,which are involved in immune response and cytokine signaling,cell growth and proliferation as well as age-related diseases such as cardiovascular diseases and neurodegenerative diseases.Overall,our study showed that a vegetarian diet modulates aging-associated circulating miRNAs in a sex-dependent manner of differential expression for certain miRNAs,which may be related in a beneficial manner to the healthspan.Further investigation is needed to validate these miRNAs as potential biomarkers for diet-modulated longevity in humans.
