The zinc intake of a group of 23 lactating and 13 nonlactating postpartum women was assessed longitudinally from 37 weeks' gestation through six months postpartum. Dietary zinc was determined by chemical analysis of three-day duplicate food and beverage composites and by calculation of three-day records. There was no significant difference between the analyzed and calculated values for daily zinc intake. Both groups of postpartum women consumed 42% or less of the Recommended Dietary Allowance (RDA) for zinc. To attain the RDA within present food selections, both groups of postpartum women would need to eat unreasonably high amounts of calories and protein.
对一组23名哺乳期和13名非哺乳期产后妇女的锌摄入量进行了纵向评估，从妊娠37周直至产后六个月。通过对三天重复的食物和饮料组合进行化学分析以及计算三天的饮食记录来确定膳食锌含量。每日锌摄入量的分析值和计算值之间没有显著差异。两组产后妇女的锌摄入量均低于推荐膳食摄入量（RDA）的42%。要在现有的食物选择范围内达到RDA，两组产后妇女都需要摄入不合理的高热量和高蛋白食物。
