医学专家的研究证实,合理膳食是防治心脑血管疾病的关键。而且四十岁前就得注意饮食的调整,才能使心脑血管疾病的发病率降到最低程度。合理膳食应该做到“两低”、“两少”、“两多”。一低,低胆固醇在膳食中应坚持食用低胆固醇、好胆固醇的食物。人的机体一方面从外界摄取一定数量的胆固醇;另一方面,是在体内不断地进行自我合成。当摄入增多时,合成便相对减少;摄入减少时,合成便显著增加,这种机制称为“反馈调节装置”。这说明,进食少量胆固醇对人体并无多大危害;而长期过量地食用高胆固醇食物会使这种装置遭到破坏,以致平衡失调而堆积在组织内部,尤其是动脉壁中会最终形成动脉粥样硬化,导致冠心病,所以,积极降低血液中的 Medical experts study confirmed that a reasonable diet is the key to prevention and treatment of cardiovascular and cerebrovascular diseases. And before the age of 40 must pay attention to the diet adjustment, in order to make the incidence of cardiovascular and cerebrovascular diseases to a minimum. A reasonable diet should be “two low ”, “two less”, “two more ”. A low, low cholesterol in the diet should insist on eating low cholesterol, good cholesterol food. On the one hand, the human body takes in a certain amount of cholesterol from the outside world; on the other hand, it constantly self-synthesizes in the body. When intake increases, the synthesis will be relatively reduced; reduced intake, the synthesis will significantly increase, this mechanism is called “feedback regulator ”. This shows that eating a small amount of cholesterol on the human body is not much harm; and long-term excessive consumption of cholesterol-rich foods will make this device was destroyed, resulting in balance disorders and accumulation in the tissue, especially the artery wall will eventually form atherosclerotic Sclerosis, leading to coronary heart disease, so, actively reduce the blood
