Gas-Producing Foods: Milk and Dairy Products. Milk and other dairy products contain a sugar called lactose, which can be difficult for your digestive tract to process if your body doesnât have enough of the enzyme lactase. Cheese, ice cream, and milk all contain lactose, and may cause excessive gas in people.
Not all types of fiber cause gas. Fiber comes in two types, soluble and insoluble. Foods that contain soluble fiber tend to produce more gas than foods high in insoluble fiber. Some sugars as well as fiber can cause gas; foods that contain both soluble fiber and sugars that cause gas have extra gas-producing potential. The types of bacteria you have in your gut -- which varies from person to person -- can also affect how much gas you produce.
