Hydrogenation of vegetable oils affects blood lipid and lipoprotein concentrations. However, little is known about the effects of hydrogenation on other components, such as vitamin K. Low phylloqui...
Our goals were 1) to compare in both a crosssectional study and a 3-y longitudinal study the bone mineral density (BMD) of postmenopausal women consuming high or low amounts of caffeine and 2) to s...
Alterations in body composition have been reported in HIV-positive adults receiving highly active antiretroviral therapy (HAART), but the magnitude and potential determinants of these changes are u...
Dietary caffeine acutely increases urinary calcium loss (1), and these losses are not entirely compensated for in the 24 h after caffeine consumption (2). Overall, the evidence indicates that young...
Vitamin D deficiency leads to secondary hyperparathyroidism, which has a negative effect on bone metabolism in the elderly. Puberty is an important time of bone metabolism and growth. The effect of...
Early diagnostic efforts and advances in multidrug therapy have considerably prolonged the survival time of children infected perinatally with HIV. Despite these advances, few studies have addresse...
Weight reduction reduces bone mineral density (BMD) and increases the risk of osteoporosis.
Different sources of dietary protein may have different effects on bone metabolism. Animal foods provide predominantly acid precursors, whereas protein in vegetable foods is accompanied by base pre...
It was first shown nearly 80 y ago, and has been confirmed many times since, that ingestion of protein increases urinary calcium excretion. Most such work involved isolated protein feedings, and qu...
Background: Chemotherapy and radiation therapy result in increased free radical formation and depletion of tissue antioxidants. It is not known whether parenteral nutrition (PN) administered during...
The low sn-2 palmitate content of infant formulas results in formation of fatty acid calcium soaps in the stools and reduced calcium absorption.
Hip fracture incidence rates are predicted to increase dramatically in the first half of the 21st century, especially in Asia, Latin America, Africa, and the Middle East. These increased rates will...
The positive association between body weight and bone mineral density (BMD) is well documented; in contrast, the effect of changes in body weight on BMD is not well understood, particularly, in nor...
Dietary calcium and milk intakes at specific ages may influence bone mineral measures at specific sites during development of peak bone mass.
