Here are some important things to know about intestinal gas:
- Everyone has gas in the digestive tract.
- People often believe they have excessive gas, even when the amount they pass is normal.
Intestinal gas comes from two main sources: swallowed air and the normal breakdown of certain foods by harmless bacteria naturally present in the large intestine.
- Many foods with carbohydrates can cause intestinal gas. Fats and proteins cause little gas.
- Foods that cause intestinal gas include:
- Vegetables such as broccoli, cabbage, Brussels sprouts, onions, artichokes, and asparagus
- Fruits such as pears, apples, and peaches
- Whole grains, such as whole wheat and bran
- Soft drinks and fruit drinks
- Milk and milk products, such as cheese and ice cream, and packaged foods prepared with lactose, such as bread, cereal, and salad dressing
- Foods containing sorbitol, such as diet foods and sugar-free candies and gums.
