脂肪肝是指人体肝细胞内蓄积了过多的脂肪.健康人肝内的脂肪只占4—7%,如果肝内脂肪含量超过15%,即可诊断为脂肪肝.脂肪肝有很多种,根据病因可分为营养性、酒精性、病毒性、内分泌性等种类.有人认为,只要不吃肥肉、少吃脂肪,就不会患营养性脂肪肝.其实,这是一种误解.人体在进行营养代谢过程中,不仅食入的食物脂肪能形成人体脂肪,而且蛋白质、碳水化合物在人体内通过生化反应,也可转化成脂肪,尤其是当这些热源质营养素过剩、超过热量代谢需要时,就会转变为人体脂肪贮存,因而越肥胖就越容易形成营养性脂肪肝.酒精进入人体后,主要在肝脏进行分解代谢.酒精对肝细胞有一定毒性,使脂肪酸的分解和代谢发生障碍,因此,饮酒越多,越容易导致酒精性脂肪肝.
Fatty liver refers to the accumulation of too much fat in human liver cells. Healthy human liver fat only 4-7%, if the intrahepatic fat content of more than 15%, you can diagnose fatty liver. Fatty liver there are many, According to the cause can be divided into nutritional, alcoholic, viral, endocrine and other species.It is believed that, as long as not eat fat, eat less fat, it will not suffer from nutritional fatty liver.In fact, this is a misunderstanding. In the process of nutritional metabolism, not only ingested food fat can form human fat, and protein, carbohydrates in the human body through biochemical reactions, can also be converted into fat, especially when these heat source nutrients excess, more than the heat metabolism needs , It will be transformed into the body fat storage, so the more obese the easier it is to form a nutritional fatty liver.When alcohol enters the body, mainly in the liver for catabolism.Alcohol has certain toxicity to liver cells, fatty acid decomposition and metabolism obstacles, Therefore, the more alcohol, the more easily lead to alcoholic fatty liver.
