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.

Long-term low-calorie low-protein vegan diet and endurance exercise are associated with low cardiometabolic risk.

BACKGROUND: Western diets, which typically contain large amounts of energy-dense processed foods, together with a sedentary lifestyle are associated with increased cardiometabolic risk. We evaluated the long-term effects of consuming a low-calorie low-protein vegan diet or performing regular endurance exercise on cardiometabolic risk factors.

Effects of meat consumption and vegetarian diet on risk of wrist fracture over 25 years in a cohort of peri- and postmenopausal women.

BACKGROUND: Evidence suggesting that a diet high in fruits and vegetables may be beneficial to bone health has sparked interest in the potential benefit of a vegetarian diet. However, other studies have raised a question regarding the adequacy of protein in such a diet. OBJECTIVE:The aim of the present study was to take a whole foods approach in examining the effects of foods high in protein on the risk of wrist fracture (WF) in a cohort with a significant proportion consuming a meat-free diet. DESIGN: A cohort study of women who completed two lifestyle surveys 25 years apart.

A randomized clinical trial of a standard versus vegetarian diet for weight loss: the impact of treatment preference.

BACKGROUND:With obesity rampant, methods to achieve sustained weight loss remain elusive. OBJECTIVE:To compare the long-term weight-loss efficacy of 2 cal and fat-restricted diets, standard (omnivorous) versus lacto-ovo-vegetarian, and to determine the effect of a chosen diet versus an assigned diet. DESIGN, SUBJECTS: A randomized clinical trial was conducted with 176 adults who were sedentary and overweight (mean body mass index, 34.0 kg/m(2)).

Overall glycemic index and glycemic load of vegan diets in relation to plasma lipoproteins and triacylglycerols.

BACKGROUND:To investigate the overall glycemic index (GI), glycemic load (GL), and intake of dietary fiber, and to examine the associations between these factors and plasma lipoproteins and triacylglycerols in adult vegans in the German Vegan Study (GVS). METHODS:Cross-sectional study, Germany. Healthy men (n = 67) and women (n = 87), who fulfilled the study criteria (vegan diet for >or=1 year prior to study start; minimum age of 18 years; no pregnancy/childbirth during the last 12 months) and who participated in all study segments.

Effects of a vegetarian diet and treatment preference on biochemical and dietary variables in overweight and obese adults: a randomized clinical trial.

BACKGROUND: A vegetarian diet may lead to numerous health benefits, including weight loss. OBJECTIVE:We examined the joint effects of personal preference of dietary treatment and a calorie-restricted, low-fat lactoovovegetarian diet (LOV-D) compared with a standard calorie-restricted, low-fat omnivorous diet (STD-D) on changes in weight, total cholesterol, ratio of LDL to HDL cholesterol (LDL:HDL cholesterol), triacylglycerols, insulin resistance, and macronutrient intake during an 18-mo study.

A two-year randomized weight loss trial comparing a vegan diet to a more moderate low-fat diet.

OBJECTIVE:The objective was to assess the effect of a low-fat, vegan diet compared with the National Cholesterol Education Program (NCEP) diet on weight loss maintenance at 1 and 2 years. RESEARCH METHODS AND PROCEDURES:Sixty-four overweight, postmenopausal women were randomly assigned to a vegan or NCEP diet for 14 weeks, and 62 women began the study. The study was done in two replications. Participants in the first replication (N = 28) received no follow-up support after the 14 weeks, and those in the second replication (N = 34) were offered group support meetings for 1 year.

Health, ethics and environment: a qualitative study of vegetarian motivations.

This qualitative study explored the motivations of vegetarians by means of online ethnographic research with participants in an international message board. The researcher participated in discussions on the board, gathered responses to questions from 33 participants, and conducted follow-up e-mail interviews with 18 of these participants. Respondents were predominantly from the US, Canada and the UK. Seventy per cent were females, and ages ranged from 14 to 53, with a median of 26 years. Data were analysed using a thematic approach.
