Dietary Protein & Bone Health: New Perspectives
Interaction of Dietary Calcium and Protein on Bone Health
The level of calcium intake may explain some of the inconsistent findings regarding protein's effect on the skeleton (9,27,35,42-44). Excess protein does not appear to harm the skeleton if calcium intake is adequate. A recent study in 342 healthy adults aged 65 years and over who had completed a three-year randomized, double-blind, placebocontrolled trial of calcium (calcium citrate malate) and vitamin D supplementation found that dietary protein is more beneficial for bones if dietary calcium recommendations are also met (27). In an accompanying editorial, the author stated, "It appears increasingly well established that protein and calcium act synergistically on bone if both are present in adequate quantities in the diet, but that protein may seem effectively antagonistic toward bone (because of its calciuric effect) when calcium intake is low" (43).
In a cohort of women enrolled in a three-year osteoporosis intervention trial, higher versus lower baseline protein intakes were associated with higher bone mineral densities of the spine, arm, and total body in women who consumed more than 408mg calcium/day (35). In contrast to the above findings, other investigations fail to identify the presence of an interaction between protein and calcium on bone mineral density (23,24,26).
