血脂主要指血液中总胆固醇(TC)和甘油三酯(TG)。胆固醇和甘油三酯过多,再加上低密度脂蛋白(LDL)做媒介,使胆固醇等在血管破损处沉积,即可引起血管硬化性病变。因此很多疾病与血脂过高有密切关系,比如血胆固醇高可引起动脉粥样硬化。这是人所共知的。 但是,不少人对血脂高低存有误解。就拿胆固醇来说,有人认为年轻人胆固醇高一些或老年人胆固醇低一些都没关系。其实,据一项研究提示,高胆固醇对年轻人也有危险。另一项研究指出,老年人低胆固醇并非都好。
Lipid mainly refers to the blood total cholesterol (TC) and triglyceride (TG). Cholesterol and triglycerides too much, coupled with low-density lipoprotein (LDL) as a medium, so that cholesterol deposition at the vascular damage, can cause hardening of the arteries. Therefore, many diseases and hyperlipidemia are closely related, such as high blood cholesterol can cause atherosclerosis. It is well known. However, many people misunderstood the level of blood lipids. Take cholesterol, some people think that young people higher cholesterol or lower cholesterol in older people does not matter. In fact, according to one study, high cholesterol is also dangerous for young people. Another study pointed out that low cholesterol in the elderly is not good.
