DISADVANTAGES OF LOW CALCIUM LEVEL

Low Calcium: A low blood calcium level usually implies abnormal function of the glands that produce parathyroid hormone responsible for regulating calcium levels. Calcium deficiency is rarely due to low dietary calcium intake since the skeleton (bones) provides a large reserve of calcium for maintaining normal blood levels. High sodium intake results in increased loss of calcium in the urine, possibly due to competition between sodium and calcium for re-uptake in the kidney. Because urinary losses account for about half of the difference in calcium retention among individuals, dietary sodium has a large potential to influence bone loss. THE NATURE CALCIUM 1000 Low Calcium: In adult women, each extra gram of sodium consumed per day is projected to produce an additional rate of bone loss of 1% per year if all the calcium loss comes from the skeleton. As dietary protein intake increases, the urinary excretion of calcium also increases. High protein intakes have be...
