Gas Prevention Diet


Although gas occurs naturally, it can be controlled or lessened with a gas prevention diet. As with any diet, there are certain foods to avoid, and there are others that work with the body to maintain a healthy, balanced digestive system.

Intestinal gas is primarily composed of hydrogen, nitrogen, and carbon dioxide — which are all gasses that are odorless. In about one-third of people, intestinal gas also contains another ingredient: methane. It’s unclear why some bodies produce methane and others do not. People who produce methane typically will have stools that float in water.

There are several possibilities that cause excessive gas:

  • Swallowing air while eating or drinking
  • Increased intestinal motility
  • Excessive bacterial fermentation of foods in the bowel
  • Smoking
  • Chewing gum
  • Drinking through a straw.
  • Foods containing sulfur
