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.

Cardiovascular disease risk factors in free-living men: comparison of two prudent diets, one based on lactoovovegetarianism and the other allowing lean meat.

In general, vegetarians have lower serum lipids and blood pressures than omnivores have. We tested the blood pressure and serum lipid lowering effects of two fat-modified diets differing primarily in their source of protein. Twenty-six men were randomized in an incomplete block design to two of three diets: a high-fat diet, a fat-modified lactoovovegetarian diet (LOV) and a diet in which 60% of plant protein in the LOV was replaced with lean meat (LM).

A salt-hypertension hypothesis.

In urban Australia, the risk of retiring with hypertension is greater than 40%, and the basic abnormality--a rise in blood pressure (BP) with age--is almost universal. A hypothesis linking this with salt, therefore, concerns everyone. The diet of early humans was unsalted, and the Na content of breast milk (6 mmol/kg) shows how little NaCl is needed even during the most rapid period of growth.

Shift from a mixed diet to a lactovegetarian diet: influence on some cancer-associated intestinal bacterial enzyme activities.

This investigation studied the effects of a shift from a mixed diet to a lactovegetarian diet on some cancer-associated bacterial enzymes in human feces (beta-glucuronidase, beta-glucosidase, and sulphatase). Three months after the shift to the lactovegetarian diet, there was a significant decrease in beta-glucuronidase, beta-glucosidase, and sulphatase activities per gram feces wet weight (p less than 0.05, less than 0.05, and less than 0.001, respectively).

Paleodietary analysis on the prehistoric population of El Hierro (Canary Islands).

In order to deepen our knowledge of the dietary habits of the prehispanic inhabitants of El Hierro, we have determined bone strontium (Sr), manganese (Mn), magnesium (Mg), copper (Cu), zinc (Zn), and calcium (Ca) in 52 human tibiae (23 belonging to males and 20 to females individuals) buried in a single burial cave; in 21 modern individuals who served as controls; and in 11 bones of herbivores found at archeological sites of the Canary Islands.

Cardiovascular risk in vegetarians and omnivores: a comparative study.

BACKGROUND: Clinical and epidemiological studies have demonstrated a strong association between eating habits and chronic diseases, particularly cardiovascular events, although not all the mechanisms of action are understood. OBJECTIVE: To describe and analyze the cardiovascular risk (CVR) in vegetarians and omnivores residing in Greater Vitória, State of Espírito Santo, Brazil, in the age range from 35 to 64 years. METHODS: To evaluate CVR in the groups, a historical cohort study with 201 individuals was conducted.

Cancer incidence in vegetarians: results from the European Prospective Investigation into Cancer and Nutrition (EPIC-Oxford).

BACKGROUND: Few prospective studies have examined cancer incidence among vegetarians. OBJECTIVE: We report cancer incidence among vegetarians and nonvegetarians in the European Prospective Investigation into Cancer and Nutrition-Oxford (EPIC-Oxford) study. DESIGN: This was a prospective study of 63,550 men and women recruited throughout the United Kingdom in the 1990s. Cancer incidence was followed through nationwide cancer registries. RESULTS: The standardized incidence ratio for all malignant neoplasms for all participants was 72% (95% CI: 69%, 75%).

Micronutrient synergy--a new tool in effective control of metastasis and other key mechanisms of cancer.

Consumption of a plant-based diet has been associated with prevention of the development and progression of cancer. We have developed strategies to inhibit cancer development and its spread by targeting common mechanisms used by all types of cancer cells that decrease stability and integrity of connective tissue. Strengthening of collagen and connective tissue can be achieved naturally through the synergistic effects of selected nutrients, such as lysine, proline, ascorbic acid and green tea extract (NM).
