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.

Newly Added Studies

             

Vitamin A intake and hip fractures among postmenopausal women.

CONTEXT:
Ingestion of toxic amounts of vitamin A affects bone remodeling and can have adverse skeletal effects in animals. The possibility has been raised that long-term high vitamin A intake could contribute to fracture risk in humans.

OBJECTIVE:
To assess the relationship between high vitamin A intake from foods and supplements and risk of hip fracture among postmenopausal women.

DESIGN:
Prospective analysis begun in 1980 with 18 years of follow-up within the Nurses' Health Study.

Excess dietary protein can adversely affect bone.

The average American diet, which is high in protein and low in fruits and vegetables, generates a large amount of acid, mainly as sulfates and phosphates. The kidneys respond to this dietary acid challenge with net acid excretion, as well as ammonium and titratable acid excretion. Concurrently, the skeleton supplies buffer by active resorption of bone. Indeed, calciuria is directly related to net acid excretion.

Effect of vegetarianism on development of gall stones in women.

Real time ultrasonography was used to compare the prevalence of gall stones in two groups of women aged 40-69: 632 women recruited from general practice registers and 130 vegetarians. One hundred and fifty-six (25%) of the 632 women who ate meat and 15 (12%) of the 130 vegetarian women either had gall stones visible on ultrasonography or had previously undergone cholecystectomy (p less than 0.01).

Attention deficit/hyperactivity disorder (ADHD) in children: rationale for its integrative management.

Attention Deficit/Hyperactivity Disorder (ADHD) is the most common behavioral disorder in children. ADHD is characterized by attention deficit, impulsivity, and sometimes overactivity ("hyperactivity"). The diagnosis is empirical, with no objective confirmation available to date from laboratory measures. ADHD begins in childhood and often persists into adulthood.

A randomized double-blind, placebo-controlled study of the effects of supplementation with highly unsaturated fatty acids on ADHD-related symptoms in children with specific learning difficulties.

 The authors tested the prediction that relative deficiencies in highly unsaturated fatty acids (HUFAs) may underlie some of the behavioral and learning problems associated with attention-deficit/hyperactivity disorder (ADHD) by studying the effects of HUFA supplementation on ADHD-related symptoms in children with specific learning difficulties (mainly dyslexia) who also showed ADHD features. (2) Forty-one children aged 8-12 years with both specific learning difficulties and above-average ADHD ratings were randomly allocated to HUFA supplementation or placebo for 12 weeks.
