人体必需的微量元素,世界卫生组织早有规定。近30多年来国际上出现了不少微量元素制剂作为食物补充剂,孕妇及小儿营养剂,预防衰老剂,治疗营养缺乏及贫血等。微量元素是指人体必需的痕迹元素(trace elements),既不能多,又不能少,多则引起毒害,少则引起疾病。医学界早已认识到铁对人体血液的重要性,人类由于外伤及内出血等原因常造成缺铁性贫血,因为没有铁,血红蛋白就不能制造,氧就不能输送,可以说贫血就意味着失铁,失铁就意味贫血,其关系非常密切。而铜这一元素则参与造血过程,主要影响铁的吸收转运和利用,它可以促使无机铁变成有机铁,使三价铁变为二价铁,后者才能被人体吸收;此外铜还参予细胞血素C,酪氨酸酶,抗坏血酸氧化酶及尿酸酶的合成。国外对生长旺盛的婴儿每日所需铜量作了规定和建议,苏联著名医学家洛曼索夫多年研究发现铜可治疗糖尿病。据报道有80多种酶的活性与锌元素有关,科学研究证实,人体含锌酶有50多种,性腺、胰腺、 The trace elements necessary for the human body have been stipulated by the World Health Organization. Over the past 30 years, there have been many trace element preparations in the world as food supplements, pregnant women and pediatric nutritional supplements, anti-aging agents, treatment of nutritional deficiencies, and anemia. Trace elements are the trace elements necessary for the human body. They can neither be more nor less, cause more poisons, and cause diseases. The medical community has long recognized the importance of iron to human blood. Human beings often suffer from iron deficiency anaemia due to trauma and internal bleeding. Because without iron, hemoglobin cannot be manufactured and oxygen cannot be transported. It can be said that anemia means iron loss. Losing iron means anaemia, and the relationship is very close. The element copper is involved in the hematopoietic process, mainly affecting the absorption and translocation of iron. It can promote the transformation of inorganic iron into organic iron, making trivalent iron become divalent iron, which can be absorbed by the body; Cytosine C, tyrosinase, ascorbate oxidase and uricase synthesis. Foreign countries have made provisions and recommendations on the amount of copper needed for the growing baby. Many years of research by the famous Soviet medical scientist Lomansov found that copper can treat diabetes. It is reported that the activities of more than 80 enzymes are related to zinc. Scientific research has confirmed that there are more than 50 kinds of zinc enzymes in the human body, such as gonads and pancreas.
