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.

Dietary trial in prostate cancer: Early experience and implications for clinical trial design.

Much epidemiologic and case-controlled evidence suggests that diet may be a modifier of prostate cancer risk. However, the role of dietary modification in men known to have prostate cancer is a matter of some debate. To elucidate the effect of diet and comprehensive lifestyle changes on cancer risk, we are conducting a randomized, prospective clinical trial on men with clinically localized prostate cancer who have selected "watchful waiting" as primary therapy.

[A low-fat and high soybean protein diet for patients with elevated serum PSA level: alteration of QOL and serum PSA level after the dietary intervention].

Considerable epidemiological evidence has indicated a relationship between diet and prostate cancer. Many studies have shown positive associations between dietary fat and prostate cancer, and inverse associations with soybean intake. To prevent prostate cancer, we have tried dietary intervention for patients showing an elevated prostate specific antigen (PSA) level.

Long-term effects of a very low-carbohydrate diet and a low-fat diet on mood and cognitive function



BACKGROUND: Very low-carbohydrate (LC) diets are often used to promote weight

loss, but the long-term effects on psychological function remain unknown.

METHODS: A total of 106 overweight and obese participants (mean [SE] age, 50.0

[0.8] years; mean [SE] body mass index [calculated as weight in kilograms divided

by height in meters squared], 33.7 [0.4]) were randomly assigned either to an

energy-restricted (approximately 1433-1672 kcal [to convert to kilojoules,

A low-fat vegan diet improves glycemic control and cardiovascular risk factors in a randomized clinical trial in individuals with type 2 diabetes


OBJECTIVE: We sought to investigate whether a low-fat vegan diet improves

glycemic control and cardiovascular risk factors in individuals with type 2


RESEARCH DESIGN AND METHODS: Individuals with type 2 diabetes (n = 99) were

randomly assigned to a low-fat vegan diet (n = 49) or a diet following the

American Diabetes Association (ADA) guidelines (n = 50). Participants were

evaluated at baseline and 22 weeks.

RESULTS: Forty-three percent (21 of 49) of the vegan group and 26% (13 of 50) of 

Chronic high-fat diet in fathers programs β-cell dysfunction in female rat offspring


The global prevalence of obesity is increasing across most ages in both sexes.

This is contributing to the early emergence of type 2 diabetes and its related

epidemic. Having either parent obese is an independent risk factor for childhood 

obesity. Although the detrimental impacts of diet-induced maternal obesity on

adiposity and metabolism in offspring are well established, the extent of any

contribution of obese fathers is unclear, particularly the role of non-genetic

High dietary intake of saturated fat is associated with reduced semen quality among 701 young Danish men from the general population


BACKGROUND: Saturated fat intake has been associated with both cardiovascular

disease and cancer risk, and a newly published study found an association between

saturated fat intake and a lower sperm concentration in infertile men.

OBJECTIVE: The objective was to examine the association between dietary fat

intake and semen quality among 701 young Danish men from the general population.

DESIGN: In this cross-sectional study, men were recruited when they were examined

Long-term effects of level of protein intake on calcium metabolism in young adult women.

The long-term effect of level of protein intake on calcium metabolism, renal function and renal acid excretion was determined during a 75-day metabolic study. Six women consumed a diet containing either 46 or 123 g protein for 60 days; they then consumed the alternate diet for 15 days. Calcium, phosphorus and magnesium intakes were maintained constant at 500, 900 and 350 mg, respectively, throughout the 75-day study.
