Abstract

The purpose of this research is to evaluate the effect of the functional diet on bone health for elder women with osteoporosis and to elucidate its effect on bone turn-over. The diet is in the form of biscuits contain whey protein and soy bean. Fourteen osteoporotic elder women were recruited in this study and given 60 g biscuits daily for one month. Serum calcium and osteocalcin (OC), urinary deoxypyridoline (U-Dpd) and Cr were measured before and after ingestion of biscuits formula. Serum calcium level was changed after one month of ingestion the biscuits formula. Serum OC concentration had increased significantly after one month of ingestion, while U-Dpd excretion had decreased significantly after one month of ingestion. There was a positive significant correlation between serum OC and U-Dpd before and after ingestion the biscuits. The intake of vitamin D of elder women with osteoporosis was marked lower than that the Recommended Dietary Allowance (RDA). Also, there was a decline in the calcium intake and a higher intake of total protein, magnesium and phosphorus than RDA. A positive significant correlation was found between plant protein and phosphorus, magnesium, zinc. The results suggested that whey protein in combination with soy bean maintaining a balance of bone remodeling in elder women with osteoporosis. It might become a novel, natural and desirable nutritional formula of bone health.
