1. Daily energy is controlled at 2000~2500 kcal. The right amount of energy can save protein consumption, enhance physical strength and promote regeneration and repair of liver cells; however, too much energy can cause weight gain and lead to fatty liver. 2. The provision of protein should be sufficient. It should generally be higher than that of healthy people. The energy provided by protein accounts for 15% of the total daily energy, of which high-quality protein should account for 50%. In liver preservation therapy, a high protein diet is given, generally 97.5-130 grams of protein is supplied daily. If there is an increase in blood ammonia, the protein intake should be limited; it is appropriate to supply protein foods with low ammonia production, with milk producing the least ammonia, eggs the second, and meat the more. Soy protein contains more branched-chain amino acids, and mixed with animal protein, it can play a more complementary role and reduce the source of ammonia; attention should also be paid to the supply of methionine, choline, lecithin and other anti-fatty liver substances, so we should eat a moderate amount of animal protein and methionine rich food every day, such as light vegetables, squid, lean meat, eggs, fish, beans and soy products, etc. 3, moderate supply of fat. The fat in the diet should not be excessively restricted, so as not to affect the body’s caloric supply and reduce appetite. However, greasy food should be avoided, especially for those whose gangrene has not yet subsided. In patients with hepatitis, bile synthesis and secretion are reduced, and fat digestion and absorption functions are weakened. Therefore, steatorrhea can occur when the fat supply is too much, while too little supply can affect the patient’s appetite and absorption of fat-soluble vitamins. Fat should be 60g/day or 20% of total caloric energy; vegetable oil is appropriate for cooking. 4, the provision of carbohydrates should be appropriately increased. Should account for 60% to 70% of the total daily energy, in order to facilitate the reserve of liver glycogen, to protect the liver and maintain the function of the liver, can be supplemented with pure sugar foods such as white sugar, glucose, candy in moderation. Hepatitis patients should not eat large amounts of sugar and high-calorie foods; consuming too much fructose and sweet snacks can affect the secretion of enzymes in the gastrointestinal digestive tract and reduce appetite; sugar fermentation and gas production can aggravate gastrointestinal distention. High-sugar, high-calorie diet causes excess nutrients, prompting the body to increase lipid substances prone to hyperlipidemia and fatty liver, thus aggravating the hepatitis lesions, so that it does not heal 5, vitamins, especially the B vitamins, vitamin C, vitamin A supply to be rich. Provide foods rich in vitamin A, such as with milk, eat more egg yolk, animal liver, carrots, leeks, cabbage, golden needles, spinach, green garlic, cabbage, etc.; eat more foods rich in vitamin B1: such as whole wheat, bean sprouts, peas, peanuts, fresh vegetables, fruits, etc.; foods containing vitamin B2 are millet, soybeans, soybean paste, eggs, dairy, etc.; containing vitamin B6 are animal liver, loin Vitamin C containing foods such as persimmon pepper, garlic, rape, wild amaranth, hawthorn, etc.; due to liver disease bile sweat secretion is impaired, the absorption of vitamin K has a certain impact (especially K1, K2), so should supply more spinach, cabbage, cauliflower, peanut oil and other foods rich in vitamin K. 6, the use of fresh and non-polluting green food, careful use of food additives, to eliminate mold (such as moldy peanuts, rice) and all kinds of spoiled food. 7, it is appropriate to use steam, boiling, braising, stewing, blanching, frying and other cooking methods. Not suitable to eat fried, fried, smoked, baked food. 8, the use of a small number of meals, three meals a day, the appropriate amount of additional meals. Diet should be regular and quantitative. 9, the diet should be light, easy to digest. Quit smoking and alcohol. 10, hepatitis patients can eat clams and other foods. But pay attention to: raw materials should be fresh, no spoilage, no pollution; clean; thoroughly heated; moderate amount, not too much.
