微量元素铜对人体健康的影响

Effects of trace element copper on human health

铜是自然界中天然存在的一种元素,主要通过食物和饮水进入人体,对人体健康具有双重作用。作为人体必需的微量元素之一,铜在人体内参与多项生理功能,铜缺乏可引起贫血等多种症状;铜过量可引起急、慢性中毒,严重者可致死亡。本文主要对铜的来源、生理功能、吸收代谢、缺乏和过量的健康危害、推荐摄入量等方面的研究进展进行综述。

Copper is a naturally existing element in nature,it mostly enters the human body through food or drinking water,and it has dual functions to human health.As one of the essential micronutrients for human health,copper is involved in many physiological functions,copper deficiency causes problems,such as anemia and neutropenia.Copper excess can lead to acute or chronic copper poisoning in human subjects,and in severe cases death.The source of the copper,the physiological functions,absorption and metabolism,deficiency,toxicity,and the recommended intake of copper will be mainly reviewed in this paper.
