Abstract:
Zinc metabolism was determined with 88Zn and 70Zn, stable isotopes of zinc, in two volunteers who went through different levels of zinc nutriture for 15 weeks. It was shown that zinc metabolic pool size could correctly reflect zinc nutriture. The difference between fasting and postprandial plasma zinc concentration was more reliable than fasting plasma zinc concentration alone. The sense of daily urinary and fecal zinc excretion were rather limi ted. In a certain sense, fecal endogenous zinc excretion was valuable for establishing recommendation dietary allowance of zinc.
