营养学、流行病学的大量资料清楚地表明,饮食中的不饱和脂肪酸具有降低血胆固醇含量的作用。近年来,若干国家已开展了大规模采用饮食防治方法的试验。这些试验的结果几乎都证明用不饱和脂肪酸代替饱和脂肪酸可使人群的平均血胆固醇含量以及冠心病的发病率和死亡率显著降低。 临床上,对于每一个高胆固醇血症患者,在限制其胆固醇和饱和脂肪酸摄入的同时,必须补充一定分量的不饱和脂肪酸。因为这样做不仅对治疗有利,而且也合乎生理 Numerous data in nutrition and epidemiology clearly show that dietary unsaturated fatty acids have a role in lowering blood cholesterol levels. In recent years, several countries have conducted trials on a large scale with dietary control methods. The results of these trials almost all demonstrate that the use of unsaturated fatty acids in place of saturated fatty acids results in a significant reduction of the average blood cholesterol level in the population and the morbidity and mortality of coronary heart disease. Clinically, for each patient with hypercholesterolemia, while limiting their cholesterol and saturated fatty acid intake, must be supplemented with a certain amount of unsaturated fatty acids. Because doing so is not only good for treatment but also physiologically
