Inflammatory bowel disease is the collective name for ulcerative colitis and Crohn’s disease, which is a common disease at present; the role of food factors in the development of IBD is unclear, but many studies have found that eliminating certain foods promotes the improvement of clinical symptoms. Recommended foods: 1. Low-fiber diet: Some experts advocate that all patients with inflammatory bowel disease should be given a low-fiber diet to help reduce intestinal symptoms. However, there are studies that prove that there are no adverse gastrointestinal symptoms during the treatment of Crohn’s disease with high fiber diet. Dietary fiber is composed of many different lignans and carbohydrates, which have different effects on the function of the gastrointestinal tract. Insoluble food fiber, such as bran, has the ability to shorten the gastrointestinal transit time and increase the frequency of defecation; soluble fiber, such as gum and guar gum, can prolong the intestinal transit time, and because of its strong ability to absorb water, is conducive to the improvement of symptoms. 2, low lactose or lactose elimination diet: inflammatory bowel disease patients often occur lactose intolerance, lactose intolerant people should still avoid consuming milk and related dairy foods 3, Crohn’s disease requires low-fat diet: Crohn’s disease patients and suffer from ileal disease or ileal resection, often occur fatty diarrhea. At this time, malabsorption of fatty acids and hydroxy fatty acid derivatives produced by intestinal bacteria can stimulate the secretion of colonic fluid and electrolytes, and aggravate the symptoms of diarrhea. Therefore, a low-fat diet is recommended for this group of patients. Maintaining a low-fat diet can help reduce the excretion of divalent cations in the form of soap salts from the feces. Calcium oxalate kidney stones are a common complication in patients with Crohn’s disease and after ileal resection. In steatorrhea, dietary oxalate absorption from the colon is increased by a number of mechanisms: the formation of insoluble calcium oxalate in the colon is reduced when unabsorbed fatty acids combine with calcium, allowing more free oxalate to be absorbed in solution; fatty acids and bile salts increase the permeability of the colon to oxalate. Therefore, limiting dietary fat and calcium supplementation is often an effective way to reduce oxalate absorption and prevent hyperoxaluria and kidney stones. Enterogenic hyperoxaluria rarely occurs in patients with ileostomy, and only general restriction of dietary fat is sufficient to prevent excessive mineral and vitamin loss in the stool in these patients. Excessive restriction of dietary fat tends to reduce the palatability of the diet and reduce the amount of food eaten, thus interfering with energy intake. 4, Chinese medicine dialectical food: the condition has a deficiency of cold and hot, food also has a cold and hot warm good tonic diarrhea, food and taste should be contrary to the nature of the disease. If the deficiency should be supplemented, the actual disease should be facilitated, the heat should be cold, attention should be paid to avoid eating food that can aggravate the disease. Diet should be light, easy to digest, non-slag and nutritious fluid or semi-liquid, avoid eating greasy, cold, spicy and other irritating foods to reduce diarrhea. (1) Fasting if diarrhea is severe, ensure sufficient water intake. (2) Those who have diarrhea with abdominal pain, urgent diarrhea or unpleasant diarrhea can eat barley porridge, apple, tea, etc. (3) When the abdominal pain is diarrhea, and the pain decreases after diarrhea, the stomach and abdomen are distended and painful, you can often eat lycopodium porridge, hawthorn, etc. (4) Those who have diarrhea when their emotions are not good, can usually make soup porridge with astragalus or lotus seeds, yam, lentils, barley, etc. Often take kumquat cakes and Chen Pi strips, etc. (5) loose stools often eat astragalus porridge, lentil and rice kernel soup, lotus seeds, yam, lentils to strengthen the spleen and benefit the qi, avoid sticky products. (6) five night diarrhea, often eat astragalus, yam, lentils, corn and other porridge soup to strengthen the spleen and benefit the stomach. Can be eaten with the seeds simmered lamb, gold cherry congee, etc. The appropriate addition of cinnamon powder, pepper powder, dry ginger powder, etc. in the soup dish has the effect of warming the spleen and stomach.
