A moderately low phosphate intake may provide health benefits analogous to those conferred by UV light - a further advantage of vegan diets.

Although exposure to ultraviolet light is often viewed as pathogenic owing to its role in the genesis of skin cancer and skin aging, there is growing epidemiological evidence that such exposure may decrease risk for a number of more serious cancers, may have a favorable impact on blood pressure and vascular health, and may help to prevent certain autoimmune disorders - in addition to its well-known influence on bone density. Most likely, these health benefits are reflective of improved vitamin D status.

Low levels of osteocalcin and leptin in serum of vegetarian prepubertal children.

BACKGROUND:Scientific literature points to the positive association between vegetarian diet and reduced risk for cardiovascular diseases, some types of cancer and diabetes. On the other hand elimination of animal products from the diet decreases the intake of some essential nutrients which may influence bone metabolism. This is a very important problem especially in childhood and adolescence, when growth and bone turnover are the most intensive. Bone metabolism is regulated by variety factors, which are involved in the bone formation and bone resorption processes.

Calcaneum broadband ultrasound attenuation relates to vegetarian and omnivorous diets differently in men and women: an observation from the European Prospective Investigation into Cancer in Norfolk (EPIC-Norfolk) population study.

Vegetarian diets have been suggested to be beneficial for bone health due to increased consumption of plant foods, including soya, or reduced consumption of meat. However, meat may also be beneficial for bone health. The evidence relating diet to bone health is based largely on studies of women, often in those at high risk of osteoporosis. Few studies have investigated dietary inter-relationships in men as well as women from general populations.

Low bone mass in subjects on a long-term raw vegetarian diet.

BACKGROUND:Little is known regarding the health effects of a raw food (RF) vegetarian diet. METHODS:We performed a cross-sectional study on 18 volunteers (mean +/- SD age, 54.2 +/- 11.5 years; male/female ratio, 11:7) on a RF vegetarian diet for a mean of 3.6 years and a comparison age- and sex-matched group eating typical American diets. We measured body composition, bone mineral content and density, bone turnover markers (C-telopeptide of type I collagen and bone-specific alkaline phosphatase), C-reactive protein, 25-hydroxyvitamin D, insulin-like growth factor 1, and leptin in serum.

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.

Serum concentration of biochemical bone turnover markers in vegetarian children.

PURPOSE: In general, most children on well-planned vegetarian diets can achieve normal growth and development. However, elimination of animal products from the diet decreases the intake of some essential nutrients, such as calcium and vitamin D, and may influence bone metabolism. This is especially important in childhood and adolescence, when growth and bone turnover are most intensive. The aim of this study was to investigate the serum concentrations of biochemical bone turnover markers in prepubertal vegetarian children.

Bone mineral density of vegetarian and non-vegetarian adults in Taiwan.

Diet is thought to be one of the leading causes of bone mineral loss in aging people. In this study, we explored the potential impact of a vegetarian diet on bone mineral density (BMD) in adult Taiwanese men and women. This was a cross-sectional study of the relationship between diet (vegetarian versus non-vegetarian) and BMD and the incidence of osteoporosis. Bone mineral density was determined in a cohort of 1865 adult male and female patients who underwent routine examination in a regional teaching hospital in Taiwan between February 2003 and February 2004.
