Some foods contain FODMAPs (various short-chain carbohydrates that are not easily broken down by the digestive system, including monosaccharides and disaccharides such as fructose and lactose, polysaccharides like fructans, and polyols such as xylitol). A small number of people are allergic to these substances, and once they consume foods containing FODMAPs, it can trigger irritable bowel syndrome.
Currently, there is no effective cure for this disease in the medical community, and the best approach is to avoid foods containing FODMAPs. Foods containing FODMAPs mainly include: fruits such as apples, apricots, cherries, grapes, mangoes, pears, and peaches; grain products such as barley and wheat; cold foods like ice cream; dairy products like milk and cheese; vegetables such as asparagus, beet leaves, cauliflower, and okra; and fungi.
