硒是一种人体生理所需要的微量元素。适量的摄入将有益于人体,过量的摄入又会对人体产生不良影响。它的生理功能是:在人体内参与酶的催化作用,主要是以谷胱甘肽过氯化物酶的形式发挥抗氧化作用,来保护细胞的细胞膜,使机体的细胞内外物质交换正常地、稳定地进行。研究表明:硒有抗肿瘤作用。那么,人体每天究竟摄入多少量才算是适宜呢?美国FNB建议;硒的供给量范围每日为50~200μg。但是,由于各地地理条件的差异,土壤和水中的含硒量差别很大,人们每天通过饮食所能获得的硒的量相差也就 Selenium is a human body needs trace elements. Moderate intake will benefit the human body, excessive intake will have adverse effects on the human body. Its physiological function is: in the human body to participate in the catalytic role of enzymes, mainly glutathione perchlorinase in the form of anti-oxidation, to protect the cell membrane, so that the body’s exchange of cells inside and outside the normal, stable To carry out. Studies have shown that: selenium has anti-tumor effect. So, how much daily intake of the human body is considered appropriate? United States FNB recommendations; selenium supply range of 50 ~ 200μg daily. However, because of the difference in geographical conditions, the amount of selenium in soil and water varies greatly.
