Chronic cholecystitis and cholelithiasis often coexist. The bile in the gallbladder is regularly and regularly discharged into the intestine, mainly to help fat digestion. The ability of the gallbladder to concentrate bile decreases between diseases, the contraction function decreases, and bile is not easily discharged, which directly affects the digestion of fats, so it is important to control the diet, which is introduced as follows: 1. High-fat diet can induce biliary colic, so it should be strictly controlled; vegetable oil can reduce cholesterol, but also to promote the conversion of cholesterol into bile acids, to prevent the formation of gallstones, so cooking with vegetable oil, avoid using lard; food should not be fried and deep-fried; avoid eating foods containing high cholesterol, such as egg yolk, fish roe, animal offal. Fat intake adults 30 ~ 40 grams per day, cholesterol daily supply of less than 300 mg, and the oil food scattered food, should not use too much at once. 2, eat more vitamin A-rich food. Because vitamin A can keep the gallbladder lining epithelial cells sound, but also can reduce the formation of cholesterol stones. In addition, you can often eat foods that inhibit the formation of gallstones. 3, increase the proportion of protein and sugar intake to ensure the caloric needs and facilitate the synthesis of liver glycogen. Protein supply is appropriate, 80~100 grams per day for adults. 4, eat less food containing too much fiber, so as not to increase the pain due to intestinal peristalsis; less slag diet can reduce the gastrointestinal stimulation. 5, avoid alcohol and other irritating food; avoid eating flatulent food, so as not to stimulate the contraction of the gallbladder and aggravate the condition. Avoid eating too acidic food, because too acidic food can make the biliary sphincter contract and aggravate the bile accumulation.
