Oil and fat intake and the occurrence of cholecystitis Under normal physiological conditions, after people eat high-fat foods, the duodenum secretes a hormone called cholecystokinin that causes the gallbladder to contract. Bile contains bile salts, which can activate lipase to help fat digestion and make fat droplets smaller, thus helping fat digestion and absorption. Patients with chronic cholecystitis or cholelithiasis are more sensitive to pain, and if they consume too much fat at this time, the secretion of cholecystokinin increases and the gallbladder contracts strongly, which aggravates the inflammation of the gallbladder and then increases the edema and congestion of the gallbladder. Therefore, patients with chronic cholecystitis and cholelithiasis should eat less fatty food, especially during the holiday season, and should be more vigilant to prevent acute attacks of cholecystitis and cholelithiasis. Acute phase The acute attack of cholecystitis should be fasted so that the gallbladder can get sufficient rest in order to relieve the pain. After the pain is relieved, the diet must be gradually adjusted according to the patient’s specific conditions. A light liquid diet or a very low-fat, low-cholesterol, high-carbohydrate liquid diet (such as rice soup, lotus root powder, etc.) can be given first, and then a low-fat semi-liquid diet or a low-fat, less residue diet can be given after further improvement. Chronic phase The chronic phase of cholecystitis diet should pay attention to the following aspects: 1, limit energy: supply normal or slightly below normal energy, about 2000kcal/day, obese people need to limit energy intake; 2, low-fat: high-fat food can promote the secretion of cholecystokinin, so that the gallbladder contraction increased, inducing biliary colic, so fat intake should be strictly limited, daily intake should be <20g, and should be strictly limited The intake of animal fats should be strictly limited. Vegetable oil helps bile excretion and can be used in moderation, but it should be evenly distributed among three meals and not too much at one meal; 3, low cholesterol: most of the excess cholesterol is re-secreted in bile, which will lead to higher cholesterol concentration in bile. Food with high cholesterol content (such as fatty meat, animal liver, kidney, brain and other offal, fish roe, crab yolk and egg yolk, etc.). 4, the right amount of protein: daily protein intake should be 50 ~ 70g, too much protein intake will increase bile secretion, affecting the recovery of cholecystitis; and insufficient protein intake is not conducive to the repair of damaged biliary tract tissue, so you should give the right amount of high-value protein (such as soy products, fish and shrimp, lean meat, egg whites, etc.) food; 5, to ensure carbohydrate intake: daily carbohydrate intake should be 250-300g of carbohydrates per day to supplement energy, increase liver glycogen and protect liver cells, mainly supply compound carbohydrates-based food, and appropriately limit the intake of simple sugars (such as granulated sugar, glucose); for combined hyperlipidemia, coronary heart disease or obese people should limit the intake of carbohydrates; 6. The food fiber can also stimulate intestinal peristalsis, facilitate laxation, promote the discharge of harmful substances such as indole and fecal odor, and prevent the onset of cholecystitis. 8.Some research shows that olive oil can promote the degradation of oil to reduce the occurrence of cholecystitis and gallstones, and the right amount of olive oil can inhibit bile secretion and facilitate the discharge of bile.
