简要总结
This study is determine the effects of dietary calcium and phytate on zinc absorption.
详细描述
Zinc absorption is tested from 2 days of consuming each of four diets with zinc-65 isotope, followed by retention monitoring in a whole body scintillation counter for 4 weeks. All four 4 experimental diets are tested with each subject, in randomized order, for a total of 16 weeks.

结局指标
主要结局
Zinc Absorption
时间窗: 16 weeks
Retention of Zinc-65 was monitored for 28 days by whole body scintillation counting. The percentage of Zinc-65 absorbed was estimated from the y-intercept of the linear portion of a semilogarithmic retention plot of percent Zinc-65 retained versus time
