我国居民缺铁缺锌问题的思考

Thinking on the Icon Deficiency and Zinc Deficiency of Our Residents

综合和分析现有文献及作者己进行的工作认为:中国居民中缺铁缺锌是相当普遍的,问题是严重的。解决我国缺铁缺锌问题,食物强化是不可缺少的,预防缺铁缺锌食物强化是最省最有效的。食盐是唯一有可能成为铁锌强化最理想的载体,以它为强化铁锌载体不会导致居民摄入食盐量增加。共沉淀铁锌是最有希望的一种铁锌营养强化剤。文中也提出我国广为使用的贫血指标及用WHO对锌的EAR评判我国居民的营养状况值得商榷。建议组织研究用共沉淀氢氧化铁为铁营养强化剤制定贫血指标,以吃无锌食物所产粪锌量来测定锌状态,和以食物实际摄入为基础的营养状况预报体系,从而推进我国微量元素营养工作。

According to the composite and analysis to the existing literature and the work that have been done by the author, we found that the icon deficiency and zinc deficiency is quite common and serious in Chinese residents. To Solve the icon deficiency and zinc deficiency problem, food strengthening is the essential and the most efficent way. Edible salt is the ideal carrier to strengthen iron and zinc and it will not cause the increasing of edible salt ingestionof the residents. Co-precipitation of iron and zinc is the most hopeful iron and zinc nutrition enhancer. This paper points out that the widely used anemia indicators in our country and the evaluation to the EAR with WHO is worthy discussion. And this paper suggests that the related organization formulate the anemia indicators by taking co-precipitation of iron and zinc as iron nutrition enhancer and determine the zinc status with the amount of fecal zinc that produces from eating no zinc contained food and build the nutrition status forecasting system based on the actural food ingestion amount to promote the nutrition work of trace elements in our country.
