Description

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.<BR>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.<BR>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.<BR>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.
