Hormonal and dietary factors in acne vulgaris versus controls.

Background: Acne vulgaris is an inflammatory skin disorder with not as yet fully understood pathogenesis. In this controlled study, we assessed acne vulgaris patients for several possible pathogenic factors such as vitamin D deficiency, vegan diet, increased body mass index (BMI) and positive anti-transglutaminase antibody. Methods: We screened 10 years of records at a family medicine clinic for patients diagnosed with acne vulgaris. In eligible subjects, we collected data regarding 25-hydroxylvitamin D levels, BMI, dietary preference and serum IgA tissue transglutaminase levels.

Web-Based Recruitment and Survey Methodology to Maximize Response Rates from Followers of Popular Diets: the Adhering to Dietary Approaches for Personal Taste (ADAPT) Feasibility Survey.

Background:Although there is interest in popular diets such as vegan and vegetarian, Paleo, and other "whole food" diets, existing cohort studies lack data for these subgroups. The use of electronic data capture and Web-based surveys in nutrition research may be valuable for future studies by allowing targeting of specific dietary subgroups. Objective:The aim was to perform a Feasibility Survey (FS) to assess the practicality of Web-based research methods to gather data and to maximize response rates among followers of popular diets.

Individual characteristics associated with changes in the contribution of plant foods to dietary intake in a French prospective cohort.

PURPOSE: Rebalancing the contribution of animal- and plant-based foods is needed to achieve sustainable diet. However, little is known concerning individual characteristics that may influence intake of plant-based foods and their changes over time.

Vitamin B-12 content in breast milk of vegan, vegetarian, and nonvegetarian lactating women in the United States.

BACKGROUND: The nutritional profile of human milk varies significantly between women, and the impact of maternal diet on these variations is not well understood. OBJECTIVE: We analyzed breast-milk vitamin B-12 concentration and vitamin B-12 supplement use pattern among women who adhered to different dietary patterns: vegan, vegetarian, and nonvegetarian. DESIGN: A total of 74 milk samples, 29 from vegan, 19 from vegetarian, and 26 from nonvegetarian breastfeeding mothers, were analyzed. RESULTS: The prevalences of low vitamin B-12 (<310 pmol/L) were 19.2% for vegans, 18.2% for vegetarian

Similarities and differences in gut microbiome composition correlate with dietary patterns of Indian and Chinese adults.

The interaction between diet and gut microbiota, and ultimately their link to health, has turned into the concentration of huge research. However, this relationship still needs to be fully characterized, particularly in case of the Asian population. We compared the fecal bacterial diversity and composition of healthy Indian and Chinese adults, ages 22-35 years, using next-generation sequencing analysis on IlluminaHiSeq 2500 platform. Our analysis revealed unique community structure, dominant Firmicutes, Actinobacteria and underrepresented Bacteroides, of Indian and Chinese gut bacteria.

Ancient Thali Diet: Gut Microbiota, Immunity, and Health.

Diet provides macronutrients (carbohydrates, proteins, and fats), micronutrients (vitamins and minerals), and phytochemicals (non-nutrient bioactive compounds). Emerging evidence suggests that above dietary components can directly impact the composition and metabolic activity of the mammalian gut microbiota and in turn, affect both physical and mental health. There is a growing recognition that rise in chronic disease burden in Western countries may due to progressive loss of beneficial bacteria and microbial diversity.

Methylmalonic Acid Levels and their Relation with Cobalamin Supplementation in Spanish Vegetarians.

Cobalamin deficiency represents a health issue for vegetarians, especially vegans, if supplements are not consumed. Vitamin B12 serum levels, traditionally used to assess the vitamin B12 status, can be normal under functional deficiency conditions. In this regard, methylmalonic acid (MMA) has proven to be a more specific marker to detect subclinical vitamin B12 deficiency. In this study, we present for the first time the cobalamin status of Spanish vegetarians using both vitamin B12 and MMA markers, and the effects of the plant-based diet and the intake of vitamin B12 supplements.
