Effect of High Phosphorus Intake on Sr85 Excretions in Man.

Abstract
Summary The effect of high phosphorus intake on radiostrontium absorption was investigated in 6 patients. Two of these were studied during low calcium diet, 2 during high calcium intake, and 2 patients during low and high calcium intake. Addition of phosphorus to the diet led to a decrease in Sr85 absorption in 3 of the 4 patients each studied during low and high calcium intake, respectively. Urinary Sr85 excretion and urinary calcium excretion were decreased during high phosphorus intake in both the low and high calcium studies. The authors wish to thank Mrs. Vernice Vankin-scott, Head Nurse, Metabolic Research Unit, for most valuable assistance in this study.
