早在1960年,有人用动物实验发现,缺铬的动物血内胆固醇显著增加,血糖升高,1/5的实验动物(大鼠)的主动脉上产生了动脉粥样硬化斑块,反之,104只服用含铬量多的饲料的大鼠,不但没有一只出现类似病变,而且寿命均活到四年。对人的调查表明,冠状动脉硬化症多发地区人群的主动脉含铬量显著降低,冠心病患者主动脉内含铬量显著低于非冠心病人,而其他金属元素未发现有此现象。血清中的含铬量也明显反映出这种关系,冠状动脉硬化患 As early as in 1960, it was found in animal experiments that chromium-deficient animals had a significant increase in blood cholesterol and elevated blood glucose. Atherosclerosis plaque was produced in the aorta of a fifth of experimental animals (rats) Of the 104 rats who took a diet containing more chromium, not only did not a single one develop a similar disease, but life lived to four years. A survey of people showed that patients with coronary atherosclerosis in aortic areas significantly decreased chromium content in patients with coronary artery aortic content was significantly lower than non-coronary heart disease patients, while other metal elements were not found in this phenomenon. Chromium in serum also clearly reflects this relationship, coronary atherosclerosis
