What food does irritable bowel syndrome eat?
1, dietary fiber
Dietary fiber refers to polysaccharide food components that are not easily digested by digestive enzymes, mainly from plant cell wall tissues, including cellulose, hemicellulose, pectin, resin and so on. It cannot be absorbed and digested in human small intestine, but it can be partially or completely fermented in large intestine. Insoluble fiber can increase fecal volume, reduce intestinal passage time and increase excretion; Soluble fiber can participate in intestinal fermentation process, reduce the PH value of large intestine, and play a certain role in regulating intestinal flora. Eating oats and flaxseed can improve constipation and abdominal discomfort in patients with constipation-predominant irritable bowel syndrome.
2. Low short-chain carbohydrate diet
Short-chain carbohydrates, such as fermented oligosaccharides, monosaccharides, disaccharides and polysaccharides. These components are difficult to be absorbed in the small intestine, which can increase the osmotic pressure of the large intestine, ferment colon bacteria and cause gastrointestinal discomfort, so foods with high short-chain carbohydrate content should be avoided. Recommended foods with low short-chain carbohydrate content are: grapes, bananas, oranges, oranges, strawberries, carrots, tomatoes, cucumbers, mung bean sprouts, lettuce, cabbage, lettuce, potatoes, oats, buckwheat, corn flour and rice. It is worth mentioning that foods with high content of short-chain carbohydrates include asparagus, beetroot, cauliflower, black beans, broad beans, red beans, green beans, soybeans, garlic, onions, mushrooms, apples, mangoes, pears, watermelons, barley, bran, coarse wheat flour, and various processed meats such as sausages, coconut milk and lactose-free milk.
