微量元素有重要的生物功能,但这些元素对动物的脂代谢有什么影响?目前所知尚少。国外虽有一些研究,但又多属流行病学调查,当然也有实验研究,则有些结果并不一致。现有人发现硒与心血管疾病的发病和死亡率呈负相关、已知心血管疾病往往与脂代谢紊乱有关,但还不清楚硒对脂代谢有何影响。还有人认为缺铜可使血液胆固醇增加,但也有否定的结果。近年来家庭用铝锅较多,铝的摄入量肯定会增多,但不知与目前高脂蛋白血症发病显多有无关系,如此等等,都要进一步探讨,可是 Trace elements have important biological functions, but what effect do these elements have on lipid metabolism in animals? Although there are some studies abroad, but many are epidemiological investigations, of course there are experimental studies, some of the results are not consistent. Existing people have found that selenium is inversely related to the incidence and mortality of cardiovascular diseases. Known cardiovascular diseases are often associated with disorders of lipid metabolism, but it is unclear what effect selenium has on lipid metabolism. Others believe that lack of copper can increase blood cholesterol, but there are also negative results. In recent years, there are many aluminum pans for home use, and the intake of aluminum will certainly increase, but I do not know whether there is a significant relationship between the incidence of hyperlipoproteinemia at present, and so on.
