Vegetarian diet, blood pressure and cardiovascular risk

his paper reviews the association between a vegetarian diet and a number of risk factors for cardiovascular disease investigated in a series of epidemiological and experimental studies. Ninety-eight Seventh-day Adventist "vegetarians" were similar to 113 Mormon omnivores for strength of religious affiliation, consumption of alcohol, tea and coffee and use of tobacco, but were significantly less obese and had significantly lower blood pressures adjusted for age, height and weight.

Vegetarian diet in the treatment of mild hypertension: a randomized controlled trial.

he effect on blood pressure of an ovo-lacto-vegetarian (OLV) diet was assessed in a randomized controlled crossover trial. Fifty-eight mild untreated hypertensive subjects recruited from the Perth Centre for the 1983 National Heart Foundation (NHF) Risk Factor Prevalence Survey were randomly allocated to one of three groups: the first maintained their usual diet throughout 12 weeks; the other two were given an OLV diet for either the first or second 6 weeks of the 12-week trial.

Vegan regimen with reduced medication in the treatment of bronchial asthma.

Thirty-five patients who had suffered from bronchial asthma for an average of 12 yr, all receiving long-term medication, 20 including cortisone, were subject to therapy with vegan food for 1 yr. In almost all cases, medication was withdrawn or drastically reduced. There was a significant decrease in asthma symptoms. Twenty-four patients (69%) fulfilled the treatment. Of these, 71% reported improvement at 4 months and 92% at 1 yr.

Vitamin B-6 status and bioavailability in vegetarian women.

t has been hypothesized that the vitamin B-6 status of vegetarians and nonvegetarians may differ in relation to bioavailability of vitamin B-6. Fasting blood samples and 24-h urine collections were obtained from 13 Seventh-day Adventist (SDA) vegetarian and 16 non-SDA nonvegetarian women aged 50-83 y. The two groups were further subdivided into vitamin users and nonusers. Dietary intake was estimated from a 3-d diet record. Plasma pyridoxal 5'-phosphate (PLP) was measured by an enzymatic method. Vitamin B-6 intakes were similar and provided 85% of the RDA for both groups.

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.

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).
