High-Fiber Diet

illustrationA high-fiber diet causes gas because the carbohydrates in high-fiber foods cannot be completely digested in the stomach and small intestine. Instead, bacteria in the large intestine convert these indigestible sugars into gas. The foods that cause gas vary from individual to individual, but experts say the biggest culprits include:

  • beans, peas and peanuts
  • cucumbers and pickles
  • cabbage, broccoli and cauliflower
  • onions
  • prunes, raisins and dried apricots
  • wheat germ and bran

Here's the problem: the same gas-producing diet that features beans, cereals, whole grains, fruits and vegetables also offers important health benefits. In fact, researchers have linked a high-fiber diet to reduced risk of coronary artery disease, bowel problems and certain cancers.

So what's a health-minded person to do? Don't give up on foods that are loaded with fiber. Try adding these foods to your diet gradually and experimenting to cut out or cut back on foods that bother you.

You might also be able to find some relief at your local pharmacy. Studies have shown that an over-the-counter preparation containing the enzyme alpha-galactosidase alleviates some of the gas caused by beans and peas. Over-the-counter products containing simethicone also may help to reduce gas.
