This way of eating removes foods that may cause gas. Gas is a normal part of digestion. But too much can cause belching, swelling, or passing gas.
Too much gas may be from the foods you eat. But some health problems can also cause gas, such as:
How Foods Cause Excess Gas
Gas is a normal by-product of digestion. Swallowing air can cause gas to build up in our stomach. This usually causes burping. Some foods increase flatulence by providing nutrients to gas-producing bacteria in the lower intestines. High-fiber foods often cause gas, especially if you are not used to eating them.
Flatulence and bloating can also be caused by lactose intolerance. This is when there is not enough of the enzyme that breaks down milk sugar.
Foods to Avoid
Use this list as a guide. These are foods and drinks that cause excess gas in many people. They may or may not cause gas in you. Try to figure out which ones cause you to have gas. A food log can help you track the foods that you eat and their effects.
Breads and Cereals
Whole grains (whole wheat, brain, oats) and whole-grain products
- Brussels sprouts
- Cantaloupe and other melons
- Citrus fruits
Milk and other dairy products, including highly fermented cheese
Meat and Beans
Beans and other legumes (baked beans, garbanzo, kidney, lentil, lima, navy, pinto)
Sugar-free hard candies and gum
- Milk and milk products (if lactose intolerant)
- Carbonated drinks
Foods To Eat
Learning which foods cause you gas and which ones do not is a process of trial and error. However, most of the foods not on this list should be fine.
- Gradually increase any intake of fiber.
- Do not chew gum. Do not talk while eating. Both can cause you to swallow air.
- Exercise can help gas pass.
- Think about meeting with a dietitian to create a meal plan that is right for you.
