Our laboratory studies calcium metabolism during lifestages of high demand, i.e., building peak bone mass during adolescence and bone loss in postmenopausal women. Calcium needs in adolescence is investigated with metabolic research camps (Camp Calcium). Calcium balance is determined as well as calcium kinetics using stable isotopic tracers, total body calcium and bone mineral density using dual energy x-ray absorptiometry, and biochemical markers of bone turnover. Our goal is to determine the influence of diet, gender, actual calcium retention and maximize development of peak bone mass. We are also studying the relationship between dairy and calcium intake and body fat maintenance in this population.

Dietary alternatives to estrogen replacement therapy for postmenopausal women are also being investigated in our laboratory. by a novel approach of Ca-41 technology. Osteoporosis is a disease characterized by decreased skeletal mass and increased susceptibility to bone fractures. The health care costs related to hip fracture alone exceed $17 billion per year in the U.S. Two strategies to prevent osteoporosis includes increasing bone mass early in life and to prevent loss later. We hope to be able to give dietary and exercise advice to help women prevent osteoporosis later in life.

The chemical form of minerals in foods and bioavailability of minerals from foods has been a theme of study in our laboratory for many years. We use isotopic tracer techniques to intrinsically label foods or salts of interest in order to study factors which enhance or inhibit absorption and their biological fate in animal models or humans. We have screened many food sources for calcium bioavailability. We have developed rat models for studying calcium kinetics and bone strength. Evaluating enhancers and inhibitors of calcium absorption by active and passive routes is our focus of one laboratory.
