I. The purpose of dietary treatment is to control the amount of dietary fat and cholesterol, supplemented with high carbohydrate. Provide sufficient nutrition to maintain the body’s caloric needs, eliminate factors that promote gallstone formation and cause pain, reduce triggers, and increase the body’s resistance. Dietary treatment measures (a) Acute phase The acute phase should be fasted to allow the gallbladder to get sufficient rest to relieve pain. Supplementation by intravenous nutrition. However, more water can be drunk and attention can be paid to the supplement of sodium and potassium salts in the beverage, which can be beneficial to the treatment of the disease. After the pain is relieved, the diet can be gradually deployed according to the condition. A light liquid diet or a low-fat, low-cholesterol, high-carbohydrate liquid diet, such as rice soup, lotus root powder, soy milk and other foods, can be given. After the condition improves, a low-fat semi-liquid diet or low-fat soft food with less residue can be given. (B) chronic period 1, caloric energy: supply normal or slightly below normal amount of caloric energy, about 8.37MJ (2000kcal)/d, obese people should limit caloric energy. 2, low fat: fatty food can promote the secretion of cholecystokinin, so that the gallbladder contraction. Bile secretion is impaired in cholecystitis, fat digestion and absorption is also affected, and more fat may induce gallbladder pain. Therefore, it is necessary to strictly limit the fat intake, <20g per day, which can be gradually increased to within 40g. Animal fats should be strictly limited, while vegetable fats help bile excretion and can be used in moderation, but should be evenly distributed in 3 meals to avoid consuming too much fat in 1 meal. 3. Low cholesterol: Most of the excessive cholesterol is re-secreted in the bile, and the concentration of bile cholesterol increases, the daily intake should be <300mg, and the severe hypercholesterolemia should be controlled within 200mg. Prohibit the consumption of foods containing high cholesterol, such as fatty meat, animal liver, kidney, brain and other offal, fish roe, crab yolk, egg yolk and other foods. 4, moderate amount of protein: supply 50 to 70g per day, too much protein intake will increase bile secretion and affect the recovery of diseased tissues; too little intake is equally detrimental to the repair of damaged biliary tract tissues. A moderate amount of high-value protein should be given, such as soy products, fish and shrimp, lean meat, egg whites and other foods. 5, carbohydrates: 300-350g per day to supplement caloric energy, increase liver glycogen, and protect liver cells. Compound carbohydrate-based food should be supplied, and the intake of simple sugars, such as granulated sugar and glucose, should be appropriately restricted; the combined hyperlipidemia, coronary heart disease and obesity should be more restricted. 6, supply rich vitamins: vitamin A has a role in preventing gallstones, helps the bile duct epithelium to grow and maintain the integrity of the bile duct, and helps repair the diseased bile duct. Other vitamins, such as vitamin C, vitamin E, B vitamins should also be fully supplied. 7, food fiber: plant fiber can increase bile salt excretion, inhibit cholesterol absorption, reduce blood lipids, normalize cholesterol metabolism, and reduce the chance of gallstone formation. Food fiber not only has a beneficial effect on the gallbladder, and can stimulate intestinal peristalsis, conducive to laxative, to promote the intestinal indole, fecal odorant and other harmful substances as soon as possible, to prevent the onset of cholecystitis. The actual fact is that you can choose foods that are high in food fiber, such as green leafy vegetables, radishes, beans, fruits, coarse grains; and mushrooms, fungus and other foods that have a cholesterol-lowering effect. 8, drink a lot of water: drink more water and beverages, can dilute bile, promote bile discharge, prevent bile stasis, is conducive to the recovery of biliary tract disease, to 1000 ~ 1500ml per day is appropriate. 9, a small number of meals: a small number of meals can reduce the burden on the digestive system, more meals can stimulate the biliary secretion of bile, keep the bile duct open, conducive to the drainage of inflammatory substances in the bile duct, and promote the slowdown and improvement of the disease. 10, dietary contraindications: stimulating foods and strong condiments, such as chili, curry, mustard, wine, coffee, etc.; fried and deep-fried and gas-producing foods, such as milk, onions, garlic, roo I,, soybeans, etc. Pay attention to hygiene to prevent intestinal parasites and bacterial infections.
