Your Online Source for Plant-Based Research Articles

Welcome to plantbasedresearch.org, 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.

Vegan Diet, Subnormal Vitamin B-12 Status and Cardiovascular Health.

Vegetarian diets have been associated with atherosclerosis protection, with healthier atherosclerosis risk profiles, as well as lower prevalence of, and mortality from, ischemic heart disease and stroke. However, there are few data concerning the possible cardiovascular effects of a vegan diet (with no meat, dairy or egg products). Vitamin B-12 deficiency is highly prevalent in vegetarians; this can be partially alleviated by taking dairy/egg products in lact-ovo-vegetarians.

Comparison of the nutritional status and outcome in thermal burn patients receiving vegetarian and non-vegetarian diets.

BACKGROUND: The importance of adequate nutritional support in burned patients cannot be overemphasised. For adequate long-term compliance by the patients, diet should be formulated in accordance with their pre-burn dietary habits, religious beliefs, and tastes. PATIENTS AND METHODS: A study was conducted in 42 consecutive patients suffering from 10% to 50% of 2(nd) and 3(rd) degree thermal burns with the aim to compare nutritional status, clinical outcome, and cost-effectiveness of vegetarian and non-vegetarian diets.

Unrestricted Paleolithic Diet is Associated with Unfavorable Changes to Blood Lipids in Healthy Subjects

The Paleolithic (Paleo) diet is one modeled after the perceived food consumption of early human ancestors of the Paleolithic Era, consisting of mainly meat, fish, fruit, vegetables, eggs, and nuts. The purpose of this study was to examine the effects of a Paleo diet on blood lipids, including high-density lipoprotein (HDL), low-density lipoprotein (LDL), non-HDL cholesterol, triglycerides (TG), total cholesterol (TC), and the ratio between TC and HDL (TC/HDL) in a healthy population.

Biologically active vitamin B12 compounds in foods for preventing deficiency among vegetarians and elderly subjects.

The usual dietary sources of vitamin B12 are animal-source based foods, including meat, milk, eggs, fish, and shellfish, although a few plant-based foods such as certain types of dried lavers (nori) and mushrooms contain substantial and considerable amounts of vitamin B12, respectively.

A comparison of high and low fat meals on postprandial esophageal acid exposure.

Fatty foods have been identified as precipitating factors in symptomatic gastroesophageal reflux (GER). A fat meal has also been found to decrease lower esophageal sphincter pressure (LESP) in normal subjects. We used the ambulatory 24-h pH monitor to assess esophageal acid exposure in 10 normal subjects and 10 GER patients following low and high fat meals eaten in two body positions. The meals had nearly identical protein content, volumes, and calories. On successive days, patients ingested one of the meals twice, followed by random assignment to 3 h upright and 3 h recumbent position.

Low Protein Intake Is Associated with a Major Reduction in IGF-1, Cancer, and Overall Mortality in the 65 and Younger but Not Older Population

Mice and humans with growth hormone receptor/IGF-1 deficiencies display major reductions in age-related diseases. Because protein restriction reduces GHR-IGF-1 activity, we examined links between protein intake and mortality. Respondents aged 50–65 reporting high protein intake had a 75% increase in overall mortality and a 4-fold increase in cancer death risk during the following 18 years. These associations were either abolished or attenuated if the proteins were plant derived.

Vegetarian diets and cardiovascular risk factors in black members of the Adventist Health Study-2.

To compare cardiovascular risk factors between vegetarians and non-vegetarians in black individuals living in the USA.

DESIGN:

A cross-sectional analysis of a sub-set of 592 black women and men enrolled in the Adventist Health Study-2 (AHS-2) cohort of Seventh-day Adventists.

SETTING:

Members of the AHS-2 cohort, who lived in all states of the USA and provinces of Canada.

SUBJECTS:

Black/African-American members of two sub-studies of AHS-2 where blood and physiological measurements were obtained.
