第一,因怕血脂高,对含胆固醇的食物不敢食用,这是错误的。胆固醇是动物脂肪中的主要成份之一,它的来源一是从摄入体内的动物脂肪中的胆固醇,其中仅约有30%被吸收,并不是摄入多少,就吸收多少;二是由体内肝脏来合成,每天约1克,所以就是吃进的食物完全不含胆固醇,体内自身仍能产生胆固醇。人体胆固醇低的害处是导致脑、心、肾、肺等组织细胞生成不健全;影响胆汁的组成,从而影响对脂肪的消化吸收;引起内分泌激素分泌不足,影响人的正常生理功能;低胆固醇还可诱发引起脑中风、心脏病和癌症,因此,完全禁食胆固醇是不可取的。正常人血清总胆固醇应在3.1至5.7之间,凡高于5.42应适当控制血脂,凡低于3.1,就为
First, because of fear of high blood lipids, the cholesterol-containing foods can not eat, it is wrong. Cholesterol is one of the main components of animal fat. One of its origins is the intake of cholesterol from animal fat in the body, of which only about 30% is absorbed and not absorbed much. Liver to synthesis, about 1 gram per day, so that is eating food completely free of cholesterol, the body itself can still produce cholesterol. The harmful effects of low cholesterol in human body are the formation of unsound tissue cells such as brain, heart, kidney and lung, affecting the composition of bile and thus affecting the digestion and absorption of fat, causing insufficient secretion of endocrine hormones and affecting the normal physiological functions of human. Low cholesterol Can cause stroke, heart disease and cancer induced, therefore, completely fasting cholesterol is not desirable. Normal serum total cholesterol should be between 3.1 to 5.7, where higher than 5.42 should be appropriate control of blood lipids, where less than 3.1, it is
