Dietary intake among young adolescents in Ontario: associations with vegetarian status and attitude toward health.

BACKGROUND:This study aimed to describe the dietary intakes of adolescent vegetarians and omnivores and determine if, and how, attitude toward personal health related to food consumption. METHODS:Among grade 9 students in Ontario, Canada (n = 630), vegetarian status and estimated consumption of foods and food groups were determined by food frequency questionnaire. Personal health was self-categorized as very important (the "health conscious") or somewhat/not important (the "non-health conscious").

Vegetarian diets: what are the advantages?

A growing body of scientific evidence indicates that wholesome vegetarian diets offer distinct advantages compared to diets containing meat and other foods of animal origin. The benefits arise from lower intakes of saturated fat, cholesterol and animal protein as well as higher intakes of complex carbohydrates, dietary fiber, magnesium, folic acid, vitamin C and E, carotenoids and other phytochemicals. Since vegetarians consume widely divergent diets, a differentiation between various types of vegetarian diets is necessary.

The effect of cooking method upon the titratable acidity of a popular vegetarian dish--scope for reducing its erosive potential?

The purpose of this in vitro study was to determine the effect of cooking method on the erosive potential of ratatouille. Two cooking methods, stewing and oven roasting, were applied to standardised ingredients taken from the same fruits and vegetables. The resultant dishes were liquidised and diluted with 100 mls of distilled water. Five 25 ml samples of each group were titrated to pH 7.0 against 0.1 Molar Sodium Hydroxide.

How does the health and well-being of young Australian vegetarian and semi-vegetarian women compare with non-vegetarians?

OBJECTIVE: To compare the sociodemographic characteristics, health status and health service use of vegetarians, semi-vegetarians and non-vegetarians. DESIGN: In cross-sectional data analyses of the Australian Longitudinal Study on Women's Health in 2000, 9113 women (aged 22-27 years) were defined as non-vegetarians if they reported including red meat in their diet, as semi-vegetarians if they excluded red meat and as vegetarians if they excluded meat, poultry and fish from their diet. RESULTS: The estimated prevalence was 3% and 10% for vegetarian and semi-vegetarian young women.

Overall glycemic index and glycemic load of vegan diets in relation to plasma lipoproteins and triacylglycerols.

BACKGROUND:To investigate the overall glycemic index (GI), glycemic load (GL), and intake of dietary fiber, and to examine the associations between these factors and plasma lipoproteins and triacylglycerols in adult vegans in the German Vegan Study (GVS). METHODS:Cross-sectional study, Germany. Healthy men (n = 67) and women (n = 87), who fulfilled the study criteria (vegan diet for >or=1 year prior to study start; minimum age of 18 years; no pregnancy/childbirth during the last 12 months) and who participated in all study segments.

A very-low-fat vegan diet increases intake of protective dietary factors and decreases intake of pathogenic dietary factors.

There is increasing evidence that dietary factors in plant-based diets are important in the prevention of chronic disease. This study examined protective (eg, antioxidant vitamins, carotenoids, and fiber) and pathogenic (eg, saturated fatty acids and cholesterol) dietary factors in a very-low-fat vegan diet. Ninety-three early-stage prostate cancer patients participated in a randomized controlled trial and were assigned to a very-low-fat (10% fat) vegan diet supplemented with soy protein and lifestyle changes or to usual care.

Monitoring of pesticide residues in vegetarian diet.

Examples (28) of complete vegetarian diet consumed from morning till night i.e. tea, milk, breakfast, lunch, snacks, dinner, sweet dish etc. were collected from homes, hostels and hotels periodically from Hisar and analysed for detecting the residues of organochlorine, synthetic pyrethriod, organophosphate and carbamate insecticides. The estimation was carried out by using multi-residue analytical technique employing gas chromatograph (GC)-electron capture detector and GC-nitrogen phosphorous detector systems equipped with capillary columns.
