Irritable bowel syndrome, or IBS, is a functional gastrointestinal disorder that affects the colon or large intestine. It involves abdominal pain, bloating, constipation and diarrhea. Up to 20 percent of U.S. adults have IBS symptoms, according to Centers for Disease Control and Prevention. Some fatty foods, such as french fries, and milk products, such as cheese and ice cream, may cause or worsen IBS symptoms. People with IBS must avoid eating these foods or eat less of them. Some foods can make IBS better.
Fruits and Vegetables
Eating more high-fiber foods can ease symptoms in patients with irritable bowel syndrome because dietary fiber keeps the colon mildly distended. this may help prevent spasms, according to the Columbia University Medical Center. Fruits and vegetables contain high levels of dietary fiber, a complex carbohydrate, which may help protect people from IBS symptoms. The Columbia University also notes that people who eat a high-fiber diet are less likely to become constipated.
Whole Grains
Whole grains are better sources of nutrient and fiber. The dietary fiber in whole grains has increasingly been shown to be important in preventing irritable bowel syndrome, according to the U.S. Department of Agriculture. The soluble fiber in whole grains softens the stool and increases its bulk. A bulky stool is easier to pass, decreasing the likelihood of constipation.
Legumes
The fiber in legumes may lower the risk of irritable bowel syndrome, according to the U.S. National Institutes of Health. Legumes are also highly regarded for their ability to prevent or relieve constipation. In general, limitations on stool mobility through the colon result in constipation. Legumes increase stool volume and water content, hastening its colonic transit time.
