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.

Bending the curve of terrestrial biodiversity needs an integrated strategy.

Increased efforts are required to prevent further losses to terrestrial biodiversity and the ecosystem services that it  provides(1,2). Ambitious targets have been proposed, such as reversing the declining trends in biodiversity(3); however, just feeding the growing human population will make this a challenge(4). Here we use an ensemble of land-use and biodiversity models to assess whether-and how-humanity can reverse the declines in terrestrial biodiversity caused by habitat conversion, which is a major threat to biodiversity(5).

Donor Fecal Microbiota Transplantation Alters Gut Microbiota and Metabolites in Obese Individuals With Steatohepatitis.

The intestinal microbiota has been linked to the development and prevalence of steatohepatitis in humans. Interestingly, steatohepatitis is significantly lower in individuals taking a plant-based, low-animal-protein diet, which is thought to be mediated by gut microbiota. However, data on causality between these observations in humans is scarce. In this regard, fecal microbiota transplantation (FMT) using healthy donors is safe and is capable of changing microbial composition in human disease.

Nutrient intake and health status of vegans. Chemical analyses of diets using the duplicate portion sampling technique.

A strict vegetarian diet [vegan diet (VD)] was investigated. Six middle-aged vegans (three men and three women) collected copies of 24-h diets using the duplicate portion sampling technique. By chemical analyses, the nutrient composition was determined in detail and compared with corresponding figures of a normal mixed Swedish diet. In the VD 30% of the energy originated from fat compared with 40% in normal Swedish mixed diet (MD). Linoleic acid was the dominant fatty acid (60% of total fat in VD versus 8% in MD).

Low blood pressure in vegetarians: the possible role of potassium.

Ninety-eight confirmed adult vegetarians were examined against a matched group of nonvegetarians living in the same urban environment in order to evaluate the prevalence of arterial hypertension. The average blood pressure was 126/77 for the vegetarians and 147/88 for the control group (p less than 0.05). Significantly lower blood pressure was found in every decade of age. Only 2% of the vegetarians had hypertension (higher than 160/95) as compared to 26% hypertensives in the nonvegetarians.

Lack of an effect of dairy protein (casein) and soy protein on plasma cholesterol of strict vegetarians. An experiment and a critical review.

In animals, ingestion of casein, the principal protein in milk, causes hypercholesterolemia, whereas in humans this effect has not been documented. We added 27 g of casein (the amount in 1.1 liters of skim milk and nearly twice the average U.S. intake) for 20 days, and 27 g of soy protein for an additional 20 days to the daily diet of 13 strict vegetarians who consumed no other animal protein during the study period. The protein supplementation increased the ad libitum daily protein intake from 59 g to 82 g.

Dietary fat intake and blood pressure: a double blind controlled trial of changing polyunsaturated to saturated fat ratio.

The effect on blood pressure of elevating the dietary polyunsaturated/saturated fat (P/S) ratio was assessed in a double-blind, randomized control trial. Fifty-four healthy, normotensive volunteers aged between 20 and 59 years were randomly allocated either to a control group who ate a low P/S ratio diet throughout, or to one of two experimental groups who ate a high P/S ratio diet for one of two six-week experimental periods. Other nutrient changes were avoided.
