Why do I have an excessive amount of gas?

You may be swallowing more air than you realize. Or, your process of digestion may be normal but might be generating more gases than before. Review your diet. Many healthy foods are gas-producing. Common ones include beans; certain vegetables, such as cabbage, brussels sprouts, broccoli, cauliflower, and peas; oat bran and other high-fiber foods; carbonated beverages; foods containing sorbitol (a sugar alcohol used in many low-calorie foods); and fructose, a natural sugar present in many fruits, including prunes, pears, grapes, dates, and figs.
