For patients with Crohn’s disease, more attention should be paid to diet and nutrient supplementation, generally a high nutrition and low residue diet, with appropriate supplementation of folic acid, vitamin B12 and other vitamins and trace elements. The following points should be noted. 1, should eat less spicy and stimulating food such as chili, pepper, garlic, mustard, pepper, ginger, etc., these foods can cause adverse stimulation of the gastrointestinal tract, and should not eat too cold and too hot food. It is worth noting that once the summer time, pay attention to avoid eating cold drinks or food just taken out of the refrigerator. 2, must eat less coarse fiber food such as soybeans, green beans, etc., because too much coarse fiber food can stimulate the intestinal tract, and will affect the absorption of nutrients, will promote the original malnutrition of the patient’s condition more serious. Therefore, it is necessary to limit fiber foods, such as celery, radish, leek and dried beans. When the disease is active, raw vegetables and fruits must be avoided, but can be made into vegetable puree, juice and other food. 3, do not eat fatty food such as fatty meat, fried food, pastry, etc. Ulcerative colitis diarrhea is accompanied by fat malabsorption, more serious can be accompanied by steatorrhea. So, to properly limit the intake of fat, can take less oil food or cooking methods, not to eat more oil food or fried food. You can also go to the hospital to check the “food intolerance 14 or 90 items”, according to the results and then adjust! 4, inflammatory bowel disease patients should be careful eating seafood seafood proteins are different from the proteins in the food we often eat, certain foreign proteins are prone to allergies, aggravating inflammatory reactions, so patients with inflammatory bowel disease must be careful eating seafood. Milk and dairy products are also not recommended during active disease. For all patients with inflammatory bowel disease, it is recommended to: eat any food that can be tolerated and create a dietary diary. It is recommended to record the daily diet and exclude intolerable foods based on bowel movements and associated symptoms (e.g., abdominal pain, bloating, etc.). These foods should be avoided in the future, and as the disease recovers, tolerance to such sensitive foods can be tested again. Finally, a “tolerated” recipe can be determined to guide the diet.
