Role of food in IBS
Most IBS patients report a worsening of symptoms following ingestion of certain foods. The most commonly implicated foods are milk and dairy products, wheat products, onions, peas and beans, hot spices, cabbage, certain meats, smoked products, fried food, and caffeine. However, the dietary composition of IBS patients is similar to the general community. There is no documented evidence showing that a food allergy or intolerance plays a role in IBS symptoms.
