The best way to protect and nourish the liver is not true, there is no best way to protect and nourish the liver. Dietary treatments such as a light diet, strengthening exercise and medications such as polyene phosphatidylcholine are often used to protect the liver. 1. Diet therapy: eat a light diet, avoid moldy food, such as moldy peanuts containing aflatoxin and the intake of carbon tetrachloride and other poisons; avoid the intake of alcoholic beverages, such as red wine, beer, white wine, etc. Alcohol can cause degeneration and necrosis of liver cells, and long-term consumption of alcohol can lead to alcoholic hepatitis, cirrhosis and other diseases, which can seriously damage the liver function. 2. Exercise therapy: strengthen aerobic exercise such as jogging and yoga. Avoid staying up all night and develop the habit of going to bed early and getting up early. 3. Drug therapy: (1) Polyene phosphatidylcholine: it can accelerate the regeneration and stabilization of hepatocytes, inhibit lipid peroxidation and collagen synthesis, thus playing a role in inhibiting steatosis and fibrosis. It can be used in various types of hepatitis, such as toxic liver injury, fatty liver and cirrhosis. (2) Thiopronin: By providing sulfhydryl detoxification to counteract liver damage, it scavenges free radicals, protects the mitochondrial structure of hepatocytes, and inhibits triglyceride accumulation caused by chronic liver injury. It is suitable for alcoholic hepatitis, drug-induced hepatitis, toxic and viral hepatitis. All of the above medications should be taken under the guidance of a physician and should not be used without authorization.
