Effects of supplementation of the diets with calcium and calcium-rich foods on bone density of elderly females with osteoporosis

CJ Lee, GS Lawler and GH Johnson

Diets of 20 elderly females with osteoporosis were supplemented daily with 2.25 oz of processed cheese, and 3 capsules of dicalcium phosphate + vitamin D containing 350 mg Ca, 270 mg P, and 399 IU vitamin D, for a 6-month period. The bone density of the 3-2 phalanx was measured densitometrically from the hand x-ray taken with a standard aluminum stepwedge. Fasting blood and urine were analyzed at the beginning and end of the experimental period. The mean bone density increased (p less than 0.05). There were 11 subjects with increased bone density, three with no changes and six with reductions in bone density. Calcium, P, and alkaline phosphatase in serum and Ca/creatinine and P/creatinine in urine were unchanged. The changes in bone density were correlated to the changes in body weight (r = 0.6529). The results suggested that, even with a mean age of 70 yr, some elderly persons can benefit from supplementary Ca and Ca-rich foods to improve bone density.
