最近十几年来,国内外对微量元素与人体健康的关系极为重视,其中锌在人体内的分布代谢及锌缺乏和锌过多对人体的危害研究较多,有一些新的看法。本文就上述几个方面的研究作一综述。 一、锌在体内的分布与代谢 微量元素锌在健康人体内的含量可有较大的差别。以血清锌测定为例,各报道可差几倍乃至近10倍。其原因在于受地理环境、职业、年龄、性别、饮食、季节以及检测方法等因素影响。由于植物性食品含锌少,我国一些以植物性食品为主食的人群,特别是儿童、青少年易致锌摄入不足,潜在性缺锌状态、应引起注意。
In the recent ten years, the relationship between trace elements and human health has been attached great importance both at home and abroad. There are many new research about the harmful effects of zinc on the human body, including the metabolism of zinc in the human body, zinc deficiency and excess zinc. This article reviews the above research. First, the distribution and metabolism of zinc in the body Trace elements of zinc in healthy human body content can have a greater difference. Serum zinc as an example, the reports can be several times worse or nearly 10 times. The reason lies in the geographical environment, occupation, age, sex, diet, season and testing methods and other factors. Due to the low zinc content of plant foods, some people in our country who take plant foods as their staple food, especially children and adolescents, may cause insufficient zinc intake and potential zinc deficiency, which should be noticed.
