Calcium can be drained by a vast number of factors. Lack of absorption may be caused by such factors as insufficient phosphorus or magnesium, lack of sunlight or Vitamin D, inflammatory bowl disease, surgery of the gastrointestinal tract, cirrhosis of the liver, and other conditions. The intestinal handling of calcium is still not well understood, but it seems that a high intake of calcium is no guarantee that the mineral will be absorbed and utilized by the body. Inactivity can prevent the formation of bone matter, as the latter is formed in response to physical stresses. The same happens to patients bedridden for a long time.
Athletes generally have denser bones than the population at large.
Brisk walking is probably the best exercise to encourage bone formation, especially for the leg, hip and spine. Besides, the solutions offered can, and often do, have considerably damaging effects. In addition, milk and milk products are greatly involved in a considerable number of symptoms and illnesses, all of which improve or disappear when dairy is eliminated. If you're still wondering where you will get your calcium, let me put your mind at rest. Wash and pick over the greens.
