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.

Chinese lacto-vegetarian diet exerts favorable effects on metabolic parameters, intima-media thickness, and cardiovascular risks in healthy men.

BACKGROUND:To investigate whether the Chinese lacto-vegetarian diet has protective effects on metabolic and cardiovascular disease (CVD). METHODS:One hundred sixty-nine healthy Chinese lacto-vegetarians and 126 healthy omnivore men aged 21-76 years were enrolled. Anthropometric indexes, lipid profile, insulin sensitivity, pancreatic β cell function, and intima-media thickness (IMT) of carotid arteries were assessed and compared. Cardiovascular risk points and probability of developing CVD in 5-10 years in participants aged 24-55 years were calculated.

Nutritional quality and acceptability of a weekly vegetarian lunch in primary-school canteens in Ghent, Belgium: 'Thursday Veggie Day'

OBJECTIVES:To determine the nutritional adequacy and acceptability to children of vegetarian lunches served on 'Thursday Veggie Day' - a public health initiative in Ghent (Belgium) primary schools. DESIGN:A comparison of food leftovers from main courses on regular days and Thursdays was made using a visual plate waste method.

Blood pressure of omnivorous and semi-vegetarian postmenopausal women and their relationship with dietary and hair concentrations of essential and toxic metals.

OBJECTIVE:This study aims to ascertain the relationships between mineral consumption, hair mineral content, and blood pressure. METHODS:The study involved 26 postmenopausal women from enclosed religious communities, 14 were semi-vegetarians and 12 were omnivores. Mineral dietary assessment was performed using a 14-d precise weight method and Food tables. Hair mineral levels were measured by means Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-OES).

The impact of vegan diet on B-12 status in healthy omnivores: five-year prospective study.

BACKGROUND:There are no long-term prospective studies assessing the impact of the vegan diet on vitamin B-12 (B-12) status. Many vegans take B-12 supplements irregularly or refuse to adopt them at all, considering them to be "unnatural" products. The use of B-12 fortified food may be an alternative. Therefore, we aimed to estimate the long-term effect of a vegan diet on serum B-12 concentrations in healthy omnivore adults, comparing the influence of natural products consumption and B-12 fortified food.

Vegetarian diet and mental disorders: results from a representative community survey.

BACKGROUND:The present study investigated associations between vegetarian diet and mental disorders. METHODS:Participants were drawn from the representative sample of the German Health Interview and Examination Survey and its Mental Health Supplement (GHS-MHS). Completely vegetarian (N = 54) and predominantly vegetarian (N = 190) participants were compared with non-vegetarian participants (N = 3872) and with a non-vegetarian socio-demographically matched subsample (N = 242).

Vegetarian diets, low-meat diets and health: a review

OBJECTIVE:To review the epidemiological evidence for vegetarian diets, low-meat dietary patterns and their association with health status in adults. DESIGN:Published literature review focusing primarily on prospective studies and meta-analyses examining the association between vegetarian diets and health outcomes. RESULTS:Both vegetarian diets and prudent diets allowing small amounts of red meat are associated with reduced risk of diseases, particularly CHD and type 2 diabetes. There is limited evidence of an association between vegetarian diets and cancer prevention.

The "vegetarian brain": chatting with monkeys and pigs?

An array of brain regions in the fronto-parietal and temporal lobes cooperates to process observation and execution of actions performed by other individuals. Using functional MRI, we hypothesized that vegetarians and vegans might show brain responses to mouth actions performed by humans, monkeys, and pigs different from omnivores. We scanned 20 omnivores, 19 vegetarians, and 21 vegans while watching a series of silent videos, which presented a single mouth action performed by a human, a monkey, and a pig.
