近年来国外报导三价铬(Cr~(3+))是人体必需的微量元素。它在机体内是以GTF(glucsoe tolerance factor)的形式存在并发挥其生物活性。在体内GTF可增强胰岛素的作用并能改善糖耐力。体内缺铬导致糖、脂代谢异常,进一步发展为糖尿病和动脉粥样硬化。在发达国家膳食中精加工米面和白糖摄取量较大,因此铬摄取量不足是导致缺铬的直接原因,而糖尿病促进体内存铬排出又加重了缺铬状态。
In recent years, foreign reports trivalent chromium (Cr ~ (3 +)) is the human body essential trace elements. It is in the body as GTF (glucsoe tolerance factor) in the form of existence and exert its biological activity. GTF in the body can enhance the role of insulin and can improve glucose tolerance. Chromium in the body leads to abnormal glucose and lipid metabolism, and further development of diabetes and atherosclerosis. Chopped rice and sugar intake in developed countries, larger dietary intake of chromium is not the direct cause of chromium deficiency caused by the excretion of chromium excretion of chromium exacerbated the status of chromium deficiency.
