摘　　要：铁是人体必需的微量元素,是血红蛋白、肌红蛋白等的重要组成部分,在人体内发挥重要的生理功能。概述了铁的生理功能,铁缺乏或过量与人体健康的关系,贫血和铁的营养状况,铁的食物来源和吸收利用等。以人体对微量元素营养成分的实际需求为导向,通过科学施用微量元素肥料改善土壤微量元素含量,培育富含微量元素的生物品种,构建“土壤-植物营养-人体健康”产业链,将成为解决铁营养缺乏的有效手段。Iron is an essential trace element for the human body. It is an important component of hemoglobin, myoglobin and others, and plays an important physiological function in the human body. The physiological functions of iron, the relationship between iron deficiency or excess and human health, status of anemia and iron nutritional, food sources and absorption and utilization of iron, etc. are summarized. Oriented by the human body′s actual demand for trace element nutrients, it is expected that improving the content of trace elements in soil through scientific application of trace element fertilizers, cultivating biological varieties rich in trace elements and building a "soil-plant nutrition-human health" industrial chain will become an effective means to solve iron nutrition deficiency.
