The liver is the largest chemical plant in the human body, undertaking important functions such as digestion, detoxification and secretion. The nutrients we eat three times a day must rely on the liver for processing in order to provide the body with the needs of life activities. In addition to material metabolism, the liver is also the largest detoxification organ in the human body, the body produces toxins, wastes, eaten toxins, liver-damaging drugs and so on must also rely on the liver detoxification. It can be said that without the liver, there is no life in the human body, and when the liver is damaged, health is damaged. Fatty liver is a lesion caused by excessive accumulation of fat in liver cells due to various reasons. Normal intrahepatic fat accounts for 3%-4% of liver weight, if the fat content exceeds 5% of liver weight, it is fatty liver, and the amount of fat can reach 40%-50% in serious cases, and the lipids of fatty liver are mainly triglycerides.
