Your Online Source for Plant-Based Research Articles

Welcome to, an online narrative review of peer-reviewed, scientific research papers and educational resources that are relevant to plant-based nutrition. Links to the abstract are included with every article, and links to the free full articles are included when possible! A narrative review is a collection of research papers supporting a particular theory - this website is by no means an exhaustive directory of all research on nutrition and disease but presents the growing body of evidence supporting the theory that whole food, plant-based diets offer the best chance for avoiding chronic disease, and in some cases, reversing it.

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).

Plant-based diet, serum fatty acid profile, and free radicals in postmenopausal women: the diet and androgens (DIANA) randomized trial.

High calorie and fat consumption and the production of free radicals are two major mechanistic pathways between diet and disease. In this study we evaluated the effect of a plant-based diet poor in animal fat and rich in (n-3) fatty acids on fatty acids of serum phospholipids and on the production of reactive oxygen metabolites (ROMs). One hundred and four healthy female postmenopausal volunteers were recruited and randomized to a dietary intervention or a control group. Dietary intervention included a program of food education and biweekly common meals for 18 weeks.

Effects of docosahexaenoic acid supplementation on blood lipids, estrogen metabolism, and in vivo oxidative stress in postmenopausal vegetarian women.

BACKGROUND:Vegetarians are generally deficient in long-chain n-3 fatty acids. Long-chain n-3 fatty acids have a beneficial effect on plasma lipid levels, and some studies showed that they had breast cancer suppression effect. One of the biomarkers of breast cancer risk is the ratio of urinary 2-hydroxyestrone (2-OHE(1)) to 16alpha-hydroxyestrone (16alpha-OHE(1)). OBJECTIVE:To investigate the effect of docosahexaenoic acid (DHA, 22:6n-3) supplementation on blood lipids, estrogen metabolism and oxidative stress in vegetarians. DESIGN:Single-blind, randomized, placebo-controlled trial.

Consumers' readiness to eat a plant-based diet.

OBJECTIVE:The aim of this study was to examine consumers' readiness to change to a plant-based diet. DESIGN:Mail survey that included questions on readiness to change, eating habits and perceived benefits and barriers to the consumption of a plant-based diet. SETTING:Victoria, Australia. SUBJECTS:A total of 415 randomly selected adults. RESULTS:In terms of their readiness to eat a plant-based diet, the majority (58%) of participants were in the precontemplation stage of change, while 14% were in contemplation/preparation, and 28% in action/maintenance.

Vegetarian eating for children and adolescents.

During the past decade, vegetarianism has risen in popularity among American families. Well-planned vegetarian diets can satisfy the nutritional needs and promote normal growth of infants and children. Research has highlighted nutritional advantages to vegetarian diets and has indicated that this style of eating can lead to lifelong healthy eating habits when adopted at a young age. Several vitamins, minerals, and macronutrients may be deficient within a vegetarian diet.

Health effects of vegetarian and vegan diets.

Vegetarian diets do not contain meat, poultry or fish; vegan diets further exclude dairy products and eggs. Vegetarian and vegan diets can vary widely, but the empirical evidence largely relates to the nutritional content and health effects of the average diet of well-educated vegetarians living in Western countries, together with some information on vegetarians in non-Western countries. In general, vegetarian diets provide relatively large amounts of cereals, pulses, nuts, fruits and vegetables.

Effects of long-term vegetarian diets on cardiovascular autonomic functions in healthy postmenopausal women.

The incidence of cardiovascular disease is higher in postmenopausal women than in premenopausal women. We hypothesized that long-term vegetarian diets might modulate cardiovascular autonomic functions measured by frequency-domain techniques in healthy postmenopausal women. A total of 35 healthy vegetarians (mean age +/- SEM 55.0 +/- 1.3 years) who had been vegetarians for > or =2 years and 35 omnivores (55.1 +/- 1.4 years) participated in this study. These subjects were all postmenopausal without hormone replacement therapy.
