我国人民硒需要量的研究 四、推荐供给量标准的补充

最近Levander根据我们以往人体硒需要量研究结果,换算为美国人的硒需要量,但换算过程中,需要个体变异数字。本文报告了用不同方法计算前报告中平均硒摄入量的标准差,以及以往推荐的硒供给量标准的根据。根据计算结果结合我国广大高硒及低硒地区居民实际摄入硒的情况,更详细地分别提出成人最低硒需要量的观察值为每日17μg,建议成人硒供给量标准为每日50μg。

Studies on Human Selenium Requirement 4. A Supplement to the Previous Report

Recently, Levander, based on our results on the study of human selenium requirement, calculates a dietary selenium recommendation for the standard North American. During the course of his calculating, information about the individual variation from mean selenium intake in detail was needed. This article gives the standard deviations calculated by different methods. It indicates that the experimental minimum requirement of adults was 17μg Se per day, the minimum physiological requirements of safety is 50μg Se per day. The latter figures are in agreement with the result of 52μg per day calculated by Levander as a safety factor of 1.3 that is suggested. Based on this figure, Levander calculated out a dietary selenium recommendation, 70 and 55μg/day for the standard North American 79-kg male and 62-kg female, respectively, after body weight has been adjusted.
