Adopting a low-fat diet is the key to the diet treatment of reflux esophagitis. Because fat can stimulate the secretion of cholecystokinin, it can reduce the tension of sphincter at the lower end of esophagus, promote gastroesophageal reflux, and reverse the pressure difference between stomach and duodenum, so that the contents of duodenum can flow back to stomach. Because too much fat will delay the emptying of the stomach, increase the discomfort of the upper abdomen and make the stomach swell. Therefore, we should pay attention to using less fat, cream and cooking oil in our diet. Boiling, stewing, stewing and steaming should be the main methods, and fried food should be avoided. Protein can stimulate the secretion of gastric acid and gastrin. Gastrin can increase the tension of lower esophageal sphincter and inhibit gastroesophageal reflux. Protein can be appropriately added to the diet, such as lean meat, milk, bean products, egg white, etc. If you pay attention to control the intake of oil and maintain a normal weight, you will have a certain foundation. Obesity will increase the pressure on the abdomen, which is conducive to the reflux of food and aggravate the condition and symptoms. Pay attention to the rational use of oil in diet and maintain the ideal weight. In diet, we should eat more digestible and soft foods, less irritating foods, and less or no foods that can reduce the tension of sphincter at the lower end of esophagus, such as strong tea, coffee, cocoa, chocolate, fresh lemon juice, fresh orange juice, tomato juice and other acidic drinks and irritating condiments, such as curry, pepper, mint and pepper. Alcohol and tobacco can reduce the tension of lower esophageal sphincter, especially alcohol can reduce the frequency of esophageal peristalsis contraction wave. The ability of esophageal acid excretion is decreased, which plays an unfavorable role in the treatment of esophagitis. Don't eat too much at dinner, and don't add meals before going to bed to avoid aggravating symptoms.
