What percentage of women consume less then the Daily Value of calcium?
Both. Increased calcium intake helps build bones by providing calcium for deposit into bone tissue and it also helps to prevent further bone loss. Bone is subject to constant turnover, both tearing down and rebuilding tissue, throughout life. During the bone-forming years, the rate of bone formation exceeds that of bone degradation, provided adequate calcium and good nutrition are available during this time of growth. As a body matures, hormonal changes take place whereby the tearing down and rebuilding processes are maintained at approximately the same pace. With time, however, the rate of degradation may exceed the rate of new bone formation, leading to bone loss. This is particularly true in postmenopausal women who are not receiving hormone replacement therapy because estrogen plays an important role in regulating this balance. When hormonal changes cause bone degradation to exceed formation, extra calcium is needed to help maintain an appropriate balance in the bone formation proc
