Foreword:

1. The parathyroid is there in the body in charge of keeping both calcium and phosphorus at balance. In the event phosphorus in the blood increased to an excess, that will in the meantime affect the equilibrium between the calcium and the parathyroid, resulting in skeleton ailment and heterotopic calcification (such as cardiac transmission barrier, arthritis and vascular sclerosis, etc.)
2. Discharge of phosphorus in the body is chiefly by way of kidney, and phosphorus comes into the body mainly by way of dietary intake, as a general rule, protein that exhibits more of physiologic value contains more phosphorus, to secure adequate intake of protein without incurring elevation of phosphorus in the blood, it is necessary to input aluminum hydroxide or calcium carbonate concurrent with dietary intake with a view to neutralize the phosphorus present in the food, so as to reduce phosphorus intake and avoid an uprising of phosphorus in the blood.
