营养学家认为,吃瘦肉过多,同样会引致动脉硬化。这种见解,来源于一种名为“同型半胱氨酸尿症”,这种病是一种先天代谢障碍病。患者的血和尿中都含有过多的同型半胱氨酸,其动脉迅速硬化,以致动脉腔变窄和拴塞,不久即死亡。同型半胱氨酸是什么呢?营养学家认为,半胱氨酸是由蛋氨酸在某种酶的催化下产生的,常吃的所有动物瘦肉都含有蛋氨酸。当然,蛋氨酸也是人体所必须的。吃瘦肉过多,蛋酸氨日含就会增多。同型半胱氨酸相应就会增加,引起动脉硬化的可能性就更大。豆制品和
Nutritionists believe that eating too much lean, can also cause atherosclerosis. This view, from a called “homocysteineuria”, the disease is a congenital metabolic disorder. Patients with excessive homocysteine in their blood and urine, their arteries rapidly hardened, causing the arterial lumen to become narrower and torn and soon to die. What is homocysteine? Nutritionists think that cysteine is produced by the methionine catalyzed by some enzyme, and all animal lean meat often contains methionine. Of course, methionine is also necessary for the body. To eat too much lean meat, ammonia will increase with ammonia. The corresponding homocysteine will increase, causing the possibility of atherosclerosis even greater. Soy products and
