When calcium intakes are deficient, calcium is leached from the bone to maintain adequate blood levels. If calcium intake remains insufficient over a long time, bones eventually grow porous and weak, or osteoporotic. Good nutrition is critical in the prevention and treatment of osteoporosis. Far too many people, particularly women, consume inadequate amounts of calcium to optimally build and maintain bones, thus compromising their bone strength and integrity.
Studies show that in many cases an effective preventive measure is simply consuming more calcium.
Calcium supplementation, especially in people whose calcium intake is extremely low, has been shown to be effective in reducing bone fragility and preventing fractures. Eating adequate amounts of calcium is especially important during adolescence, a time bones are growing and calcium stores can be built up. Many intestinal disorders such as gallbladder disease, diverticulosis, and liver disease have important dietary components. Recent attention has focused on a number of new areas including the role of vitamin C in the prevention of cataracts and the use of B vitamins in the reduction of cardiovascular disease.
