Spinal bone mineral density in premenopausal vegetarian and nonvegetarian women: cross-sectional and prospective comparisons.

OBJECTIVE:To compare spinal bone mineral density (BMD) and 1-year BMD change between premenopausal vegetarian and nonvegetarian women. DESIGN:Cross-sectional comparison of spinal BMD at baseline and prospective comparison of a subsample. SETTING:A western Canadian metropolitan area. SUBJECTS/SAMPLES:Healthy vegetarian (n = 15 lacto-ovo-vegetarian, n = 8 vegan) and nonvegetarian (n = 22) women aged 20 to 40 years, with regular menstrual cycles and stable body weight completed baseline measurements.

The Oxford Vegetarian Study: an overview.

The Oxford Vegetarian Study is a prospective study of 6000 vegetarians and 5000 nonvegetarian control subjects recruited in the United Kingdom between 1980 and 1984. Cross-sectional analyses of study data showed that vegans had lower total- and LDL-cholesterol concentrations than did meat eaters; vegetarians and fish eaters had intermediate and similar values. Meat and cheese consumption were positively associated, and dietary fiber intake was inversely associated, with total-cholesterol concentration in both men and women.

[Results of a dynamic study on the status of health and nutrition of a Siberian vegan settlement].

In 1996 for the first time a study of state of health, living conditions and nutrition status of 84 persons from the Siberian settlement of the rigorous vegetarians--vegans and 26 aboriginal inhabitants who feed on a traditional mixed diet was carried out. The clinical and laboratory investigations are kept. The positive influencing vegan ration on a serum lipids, body weight, state of cardiovascular system was showed. The contents of vitamin B12 and serum iron in vegans was in normal physiological range. The level of blood calcium was reduced in comparison with control.

Changing from a mixed to self-selected vegetarian diet--influence on blood lipids.

OBJECTIVE:To observe any changes in serum concentrations of lipids, when UK meat-eaters switch to a self selected vegetarian diet for 6 months. DESIGN:Observational study using capillary blood samples and 3-day estimated dietary diary. SETTING:Free-living subjects in the North-West of England. SUBJECTS:Twelve male and 31 female adult volunteers aged between 18 and 42 years. OUTCOME MEASURES:Serum lipids; nutrient intake and anthropometric measurements at baseline and 6 months after switching to a self-selected vegetarian diet.

Effect of changing to a self-selected vegetarian diet on anthropometric measurements in UK adults

BACKGROUND:Vegetarians are often a little leaner compared with nonvegetarians and suffer less from obesity and its associated complications than nonvegetarians. Whether this is because of not eating meat specifically is unclear. OBJECTIVE:We investigated whether changing to a self-selected vegetarian diet resulted in changes to anthropometric measurements. Design Subjects (n = 33; seven males and 26 females) who were in the earliest stages of becoming vegetarian were observed for 6 months.

Long-term ovo-lacto vegetarian diet impairs vitamin B-12 status in pregnant women.

A well-planned vegetarian diet has been stated to be adequate during pregnancy. The aim of the present study was to compare serum vitamin B-12 and homocysteine concentrations in pregnant women (n = 109) consuming vegetarian and Western diets and to evaluate the adequacy of current dietary reference intakes of vitamin B-12 for these women. Pregnant women adhering to vegetarian diets for at least 3 y, with subgroups of ovo-lacto vegetarians (OLVs; n = 27), low-meat eaters (LME, n = 43), and women eating an average Western diet (control group, n = 39), were recruited.

Weight gain over 5 years in 21,966 meat-eating, fish-eating, vegetarian, and vegan men and women in EPIC-Oxford.

BACKGROUND:Cross-sectional studies have shown that vegetarians and vegans are leaner than omnivores. Longitudinal data on weight gain in these groups are sparse. OBJECTIVE:We investigated changes in weight and body mass index (BMI) over a 5-year period in meat-eating, fish-eating, vegetarian, and vegan men and women in the UK. DESIGN:Self-reported anthropometric, dietary and lifestyle data were collected at baseline in 1994-1999 and at follow-up in 2000-2003; the median duration of follow-up was 5.3 years.
