The basic principle of focusing on dietary prevention and control is to have a reasonable structure and balanced diet. Adhere to the program of plant-based food, supplemented by animal-based food, in line with the principles of low calories (no more than the caloric requirements of standard body weight), low fat (avoid fried food as much as possible), high protein (use soybeans, fish and shrimp and other high-quality protein as much as possible), high fiber (coarse grains or fiber-rich vegetables), more vitamins and less salt. At the same time, pay attention to the regular diet and avoid overeating. 1, early diagnosis and treatment, interrupt the development of the minimum time frame for fatty liver caused by heavy drinking is 5 years, and the minimum time frame for liver cirrhosis is 10 to 15 years. Heavy drinking is a high-risk factor for the development of alcoholic fatty liver into liver fibrosis and liver cirrhosis. If alcoholic fatty liver is not effectively prevented and treated, it can further develop into alcoholic hepatitis and alcoholic cirrhosis. Therefore, early diagnosis and treatment is necessary to stop its further development and deterioration. 2, abstinence from alcohol is the fundamental measure of treatment so far there is no special drug for the treatment, abstinence from alcohol is still the most effective treatment measures. As long as patients with alcoholic fatty liver are based on complete abstinence from alcohol, together with a scientific and reasonable diet, the fat in the liver can gradually disappear in 2 to 4 weeks, and they can recover as usual in about 3 months. 3, pay attention to the basic principle of diet prevention and control is a reasonable structure, balanced diet. Adhere to the program of plant-based food, supplemented by animal-based food, in line with the principles of low calorie (not more than the standard weight of calorie requirements), low fat (as far as possible to avoid fried food), high protein (as far as possible to use soy, fish and shrimp and other high-quality protein), high fiber (coarse grains or fiber-rich vegetables), more vitamins, less salt. Also pay attention to the regular diet and avoid overeating. Many foods have the effect of preventing fatty liver, may be more food, such as cucumber, radish, carrot, winter melon, garlic, bitter melon, tomatoes, etc. contains rich vitamins, fiber; soybeans, mung beans, black beans and their products are a source of high-quality protein; kelp, seaweed, fish and other aquatic products can promote the deposition of fat in the liver to subside. 4, pay attention to drug prevention and control in the premise of complete abstinence from alcohol, at the same time with a scientific and reasonable diet, alcoholic fatty liver recovery is not ideal, under the guidance of doctors can be used under the discretion of drug-assisted treatment. Although there is no clear special drug, but there are some drugs through the regulation of blood lipids, reduce fatty liver deposits, release alcohol toxicity to the liver, protect the liver cell membrane and improve liver function and other synergistic effect, can achieve the purpose of treatment.
