Abstract
The authors had reported previously that the amount of Sr-90 excreted by the rats fed on the high calcium diet had been higher than that of the low calcium diet group.
In this report, the relation between the Na-phytate intake and the excretion of Sr* and Ca metabolism was investigated, because of interfering action of phytic acid to calcium absorption.
When the amount of Sr* excreted in feces and urine and uptake on femur were observed, there was no significant difference between two groups fed on Na-phytate diet and control diet.
From the results of this experiment, it seems that the existence of an adequate amount of calcium in diet will diminish the interference of phytic acid on calcium metabolism.
