Calcium is deficient in most of our diets.
This deficiency is most prevalent in women who have had children and have never supplemented their own diets with calcium. Calcium consumption, along with exercise, is the best means to prevent calcium deficiency. Once calcium from bone is lost and signs of osteopenia develop, this medical problem may be hard to reverse. Collapse of bone and fractures commonly of the pelvis may occur in such individuals. Bone density studies can be used to determine the extent of osteopenia.
