现在已知引起动脉硬化和冠心病的关键因素并不是体内胆固醇总量的增加,而是体内高密度脂蛋白和低密度脂蛋白之比。这两种脂蛋白共同担负着运送胆固醇的使命,但高密度脂蛋白由于粒子小,结构密实,能自由进出动脉壁,故能清除存积于血管壁的胆固醇。低密度脂蛋
It is now known that atherosclerosis and coronary heart disease caused by a key factor is not the increase in total cholesterol, but the body of high-density lipoprotein and low-density lipoprotein ratio. Both of these lipoproteins share the mission of transporting cholesterol. However, high-density lipoproteins can remove cholesterol stored in the blood vessel walls because they are small in size and compact in structure and can freely enter and exit the arterial wall. Low-density lipids
