Irritable bowel syndrome, or IBS, affects the large intestine and causes diarrhea, constipation, or both. You may also experience bloating and abdominal pain with IBS. The exact cause of IBS is not known, states the National Institute of Diabetes and Digestive and Kidney Disease. Dietary changes may help IBS. While there are no prohibited foods for IBS, some foods may be easier on the digestive system. Consider meeting with a dietitian for help in planning a healthy IBS diet.
Grains
Fiber found in whole grains may help constipation symptoms. Whole grains include whole wheat, brown rice, millet and corn and wheat bran. These grains contain insoluble fiber which aids digested food in moving through the digestive system and preventing constipation. Consider choosing whole grain products, such as pasta, bread and bread products, over those made with refined white flour.
Produce
Produce such as fruits and vegetables contain soluble dietary fiber which forms a gel when combined with water. In the intestine, soluble fiber soaks up too much fluid, preventing diarrhea, yet produces a bulk fiber needed to move stool through the intestines to help with constipation. MedlinePlus suggests consuming produce such as beans, oranges and citrus fruits and apples and pears with skins left on. Consuming too much fiber all at once may increase bloating, intestinal gas and abdominal discomfort, warns MayoClinic.com.
Consider keeping a food diary by writing down your daily food intake and any IBS symptoms that occurred. A food diary will help you pinpoint specific foods, or amounts of food that may be problematic. Keep track of how much dietary fiber you consume and monitor your body's reaction so you can make adjustments as needed.
Dairy with Probiotics
Dairy products with probiotics, such as yogurt, may be easier on your system if you have IBS, states the National Institute for Diabetes and Digestive and Kidney Diseases. Yogurt contains bacteria known as probiotics, which are found naturally in the intestines and help aid digestion. IBS may cause lower levels of probiotics to live naturally in the intestine, which may cause bouts of diarrhea or constipation related to the disease.
Non-caffeinated Beverages
Caffeinated beverages may increase intestinal spasms and IBS symptoms, states FamilyDoctor.org. Stay away from caffeinated coffee, tea and soda. Water may help ease IBS symptoms by helping intestinal motility and the movement of solids through the intestine. Drink several glasses of water throughout the day.
