Book excerpt: Abstract: To determine the effects of protein, calcium, and phosphorus intake on calcium, phosphorus, and magnesium metabolism, calciuria was studied, and the effect of 2 levels of phosphorus on the calcium, phosphorus, and magnesium metabolisms at 2 levels of calcium was studied. An increase of phosphorus intake significantly decreased urinary calcium at both calcium intake levels, calcium absorption at 2400 mg calcium intake, and magnesium absorption and urinary magnesium, and significantly increased phosphorus absorption and urinary phosphorus. An increase of calcium intake significantly increased calcium absorption and urinary calcium, and significantly decreased phosphorus and magnesium absorption and urinary phosphorus and magnesium. Increase of dietary phosphorus increased phosphorus retention and increase of dietary calcium increased calcium retention but reduced magnesium retention. Increase of both phosphorus and calcium significantly decreased magnesium absorption and retention and urinary magnesium.
