Effect of phosphorus and calcium on zinc metabolism in man
The effect of phosphorus on zinc metabolism was studied in adult men receiving different calcium intakes ranging from 200 to 2000 mg/day. The diet and urinary and fecal excretions were analyzed for Zn, P and Ca. Metabolic balances of these elements were determined for several weeks in each study phase. In control studies the dietary intake was 800 mg/day and in the experimental studies it was increased to 2000 mg/day by adding sodium glycerophosphate to the constant diet. The dietary Zn intake averaged 14.5 mg/day in the different studies. These studies have shown that increasing the P intake by a factor of 2.5, from 800 to 2000 mg/day, did not affect urinary or fecal Zn excretions nor the Zn balance. Similar results were obtained on increasing the Ca intake from 200 to 2000 mg/day.
