人体铁的吸收及其机制是几世纪前至今研究的重要课题之一。1937年制定了精密的血清铁测定方法及1939年应用放射性同位素以后,有关铁的吸收及其机制在40～60年代有了重大突破,最近几年又有新的进展。目前大量研究证明,不论发展中国家或工业化国家。人血中缺铁都相当严重。饮食质量低劣,营养不良,有慢性失血疾病者,尤其早产儿,低出生体重婴儿,妇女及孕妇缺铁更为普遍。有报告指出,18个国家中40岁 The absorption of human body iron and its mechanism are one of the important topics studied a few centuries ago. In 1937, a precise serum iron determination method was established and the application of radioisotopes in 1939 had a major breakthrough in the absorption and mechanism of iron from the 40s to the 60s. In recent years, new progress has been made. At present, a large number of studies have proved that no matter in developing countries or industrialized countries. Iron deficiency in human blood is quite serious. Poor diet, malnutrition, chronic hemorrhagic disease, especially premature children, low birth weight infants, women and pregnant women, iron deficiency is more common. It has been reported that 40 of the 18 countries
