BACKGROUND Evidence is increasing for positive effects of fruit and vegetable intakes on bone health. However, most of the studies to date were conducted in adults, and few reports included adolescents. OBJECTIVE We explored the association between bone mineral status and fruit and vegetable intakes in adolescent boys and girls (aged 16-18 y), young women(More)
Dietary strategies to prevent and treat osteoporosis focus on increased intake of calcium and vitamin D. Modification of whole dietary patterns and sodium reduction may also be effective. We examined the effects of two dietary patterns and three sodium levels on bone and calcium metabolism in a randomized feeding study. A total of 186 adults, aged 23-76 y,(More)
The growth and development of the human skeleton requires an adequate supply of many different nutritional factors. Classical nutrient deficiencies are associated with stunting (e.g. energy, protein, Zn), rickets (e.g. vitamin D) and other bone abnormalities (e.g. Cu, Zn, vitamin C). In recent years there has been interest in the role nutrition may play in(More)
The PIXImus dual-energy X-ray absorptiometer (DXA) is designed to measure body composition, bone mineral content (BMC), area (BA), and density (BMD) in mice and rats. The aims of this study were to longitudinally measure BMC, BA, and BMD in growing rats and to identify potential technical problems associated with the PIXImus. Total femur and lumbar DXA(More)
OBJECTIVE To evaluate the effects of nutrient intake and vitamin D status on markers of type I collagen formation and degradation in adolescent boys and girls. DESIGN Cross-sectional study. SETTING Canton of Vaud, West Switzerland. SUBJECTS A total of 92 boys and 104 girls, aged 11-16 y. Data were collected on height, weight, pubertal status(More)
OBJECTIVE To investigate the effects of increasing Cu intakes, above the usual dietary intake, on biomarkers of bone metabolism in healthy young adult females (aged 21-28 y) over a 4 week period. DESIGN A double-blind, placebo-controlled randomised repeat crossover Cu supplementation trial. SETTING The study was conducted at the Royal Veterinary and(More)
The incidence of hip and forearm fracture in elderly men in the United Kingdom is a public health issue, but there is limited knowledge on lifestyle factors affecting male bone health. The aim of this cross-sectional study was to evaluate the relationships between whole body and regional bone mineral status and self-reported participation time in no-, low-,(More)
Populations with insufficient ultraviolet exposure and who consume diets low in vitamin D have low vitamin D status (plasma 25-hydroxyvitamin D (25(OH)D) concentrations) and a reported higher incidence of multiple sclerosis (MS). The active form of vitamin D, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), is an effective anti-inflammatory molecule. No research to(More)
The effect of calcium carbonate supplementation on bone growth and mineral accretion was studied in 143 boys aged 16-18 yr, randomized to 1000 mg Ca/d or a matching placebo for 13 months. Anthropometry and dual-energy x-ray absorptiometry of the whole body, lumbar spine, hip, and forearm were performed before, during, and after the intervention. The(More)
The influence of Ca supplementation of the usual diet for 14 d on biochemical markers of bone turnover was investigated in healthy young adults aged 21-26 years. In a crossover study, eighteen subjects (five male and thirteen female) were randomly assigned to their self-selected diet (about 22 mmol Ca/d) or their self-selected diet with a 20 mmol/d Ca(More)
