20名患有骨质疏松症的老年女性的饮食中每天补充2.25盎司的加工奶酪，以及3粒磷酸氢钙+维生素D，其中钙350 mg，磷270 mg，维生素D 399IU，为期6个月。3-2指骨的骨密度由标准铝阶梯形手X线片进行密度计量学测量。在实验期开始和结束时进行空腹血和尿液分析。平均骨密度增加(p<0.05)。有11名受试者骨密度增加，3名无变化，6名骨密度下降。血清钙、磷、碱性磷酸酶、尿钙/肌酐、磷/肌酐无明显变化。骨密度的变化与体重的变化呈正相关(r=0.6529)。结果表明，即使在平均年龄为70岁的情况下，一些老年人也可以从补充钙和富钙食物中受益，以提高骨密度。
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.
