Dietary intakes of adolescent females consuming vegetarian, semi-vegetarian, and omnivorous diets.

PURPOSE:To determine the energy and nutrient intakes of some omnivorous and vegetarian female adolescents to compare their risk for nutrient inadequacies. METHODS:A convenience sample of 78 lacto-ovo-vegetarians (LOV), 15 semi-vegetarians (SV), and 29 omnivorous (OM) females aged 14-19 years completed three-day weighed records from which mean intakes and major food sources of energy, nutrients, and dietary fiber (as nonstarch polysaccharides (NSP)) were calculated.

[Estimation of action of lactoovovegetarian and vegan diets on blood level of atherogenic lipoproteins in healthy people].

The biochemical status of 72 vegetarians (aged 40-60) was studied; 35 persons kept to a lactoovovegetarian diet and 37 persons followed a vegan diet (vegetable food only). As the results of the investigation showed, almost all of the biochemical parameters of blood tests in the both groups were kept to the physiological norm.

The factors associated with the belief that vegetarian diets provide health benefits.

The aim of this paper is to examine the factors associated with the belief that vegetarian diets provide health benefits. A random population mail survey about food choice was conducted among a sample of 1000 South Australians. An additional (non-random) survey of 106 vegetarians and semi-vegetarians was also conducted, giving a total of 707 participants from both samples.

German vegan study: diet, life-style factors, and cardiovascular risk profile.

BACKGROUND/AIM:Evaluation of cardiovascular risk profile in 154 German vegans. METHODS:Cross-sectional study, Germany. Study instruments: 2 FFQ, 2 questionnaires, analyses of fasting venous blood samples. RESULTS:The total study population had a low BMI (mean: 22.3 kg/m(2)), a moderate blood pressure (mean: 120/75 mm Hg), an extremely low consumption of alcohol (mean: 0.77 g/day) and 96.8% were nonsmokers. Moderate physical activity (PAL) was reported by nearly 50%, whereas 22.7% declared to have a high PAL (>3 h/week).

Public views of the benefits and barriers to the consumption of a plant-based diet.

OBJECTIVE:The aim of this study was to examine consumers' perceived benefits and barriers to the consumption of a plant-based diet. DESIGN:Mail survey that included questions on perceived benefits and barriers to the consumption of a plant-based diet. SETTING:Victoria, Australia. SUBJECTS:Four hundred and fifteen randomly selected Victorian adults. RESULTS:The main perceived barrier to adoption of a plant-based diet was a lack of information about plant-based diets (42% agreement). Sex, age and education differences were present in over a quarter of the barrier items.

Alteration of cardiovascular autonomic functions by vegetarian diets in postmenopausal women is related to LDL cholesterol levels.

This study was designed to test the hypothesis that alteration of cardiovascular autonomic functions by vegetarian diets in healthy postmenopausal women is related to lipid metabolism. A total of 70 healthy postmenopausal women not on hormone therapy participated in this study: 35 were vegetarians (mean age 55.0 years) and 35 were omnivores (mean age 55.1 years). Cardiovascular autonomic functions and baroreflex sensitivity were evaluated by specific frequency-domain measures of heart rate variability (HRV) and arterial blood pressure fluctuation.

Quantifying the food sources of basal vitamin d input.

Cutaneous synthesis and traditional food sources do not fully account for unsupplemented vitamin D status. Non-traditional food sources may be an undiscovered input. In a cohort of 780 non-supplement-taking adults with a mean serum 25-hydroxyvitamin D [25(OH)D] of 33 (±14)ng/ml we assessed the relationship between vitamin D status and selected food sources. Serum 25(OH)D concentration was adjusted for season, UVB exposures, and body size. These adjusted values were then regressed against multiple food items and combinations.
