Calcium also plays a crucial role in the health of the nervous system, strengthening cell membranes, hormone formations, blood clotting, and regulating cardiovascular physiology. Scientific research indicates that calcium deficiency is a major cause of osteoporosis. Osteoporosis is a condition in which bones become weak, fragile, and brittle. Our bones need calcium to stay strong, preserve bone mass, and reduce the risk of fracture. Healthy bones require that that you eat foods rich in calcium such as cheese, yogurt, salmon, tofu, and broccoli.
Milk is a particularly good source of calcium.
Two glasses of milk provide about 600 mg. Calcium supplementation, in addition to proper nutrition and exercise, promotes bone strength and reduces the risk of osteoporosis. Calcium and aging - Calcium is less efficiently absorbed as we age. Loss of bone is painless in the early stages. You may not know you are losing bone mass until you have a fracture.
