Several foods and drinks can help reduce intestinal gas, either by relaxing the muscles in your digestive tract, replacing gas-producing ingredients in your diet, or helping food move through more efficiently. The average person passes gas 14 to 23 times a day, so some gas is completely normal. But if bloating and discomfort are a regular problem, what you eat (and how you prepare it) can make a real difference.
Ginger
Ginger is one of the most reliable foods for gas relief. It contains compounds called gingerols that both prevent and relieve gas and bloating in the upper digestive system. Gingerols work by helping food move through your stomach more smoothly, reducing the chance that it sits and ferments. Fresh ginger sliced into hot water makes a simple tea, or you can grate it into stir-fries, soups, and dressings. For nausea-related bloating, studies have used 500 to 1,500 milligrams of ginger root daily with good results.
Peppermint
Peppermint contains menthol, which relaxes the smooth muscles lining your digestive tract. This calming effect reduces spasms and overactivity in the gut, letting trapped gas pass more easily instead of building up. Peppermint tea after a meal is the simplest approach. If you deal with frequent cramping alongside gas, peppermint oil capsules (designed to dissolve in the intestines, not the stomach) are also widely available.
Fennel Seeds
Fennel seeds contain an oil called anethole that relaxes the gastrointestinal muscles in a way similar to peppermint. They also contain insoluble fiber that may reduce the amount of gas your gut produces in the first place. In many cultures, people chew plain or sugar-coated fennel seeds after meals specifically to prevent bloating.
You only need about 1 teaspoon to 1 tablespoon of dried seeds. Crushing or grinding them just before use releases more of the active oils. You can steep them in hot water for tea, toast them and sprinkle them over dishes, or simply chew a pinch after eating.
Low-FODMAP Fruits and Vegetables
Some of the biggest gas producers are foods high in FODMAPs, a group of short-chain carbohydrates that ferment rapidly in the large intestine. If certain fruits and vegetables consistently give you trouble, swapping to lower-FODMAP alternatives can help significantly. Up to 75% of people with irritable bowel syndrome see improvement on a low-FODMAP approach.
Fruits that tend to cause less gas include grapes, strawberries, pineapples, and bananas that aren’t fully ripe. Apples, watermelon, and stone fruits (peaches, plums, cherries) are higher in fermentable sugars and more likely to cause problems. For vegetables, options like zucchini, bell peppers, carrots, and spinach are generally well tolerated, while broccoli, cabbage, asparagus, and cauliflower are more likely to produce gas because they’re rich in insoluble fiber that gut bacteria ferment.
How You Prepare Beans Matters
Beans and legumes are notorious gas producers because they contain complex sugars called oligosaccharides that your body can’t break down on its own. Gut bacteria do the job instead, producing gas as a byproduct. But you don’t have to avoid beans entirely.
Soaking and cooking beans significantly reduces these gas-producing sugars. Research published in the Journal of the American Dietetic Association found a considerable decrease in oligosaccharides in chickpeas and kidney beans after soaking and boiling. The longer you soak (overnight is ideal), the more of these sugars dissolve into the water. Always discard the soaking water and cook in fresh water. Canned beans, which have already been soaked and cooked, tend to cause less gas than dried beans prepared quickly.
If beans still bother you, enzyme supplements containing alpha-galactosidase can help. These break down the problematic fiber before it reaches your large intestine, preventing the fermentation that creates gas. You take them with your first bite of a meal. More than 20% of the population has difficulty digesting these complex carbohydrates, so this is a common issue.
Introduce Fiber Gradually
Fiber is essential for digestion, but adding too much too quickly is one of the most common causes of sudden gas problems. Insoluble fiber from whole grains, legumes, and cruciferous vegetables passes through your stomach undigested and becomes food for the trillions of microorganisms in your gut. They break it down through fermentation, and gas is the byproduct.
When fiber has been largely absent from your diet, your gut bacteria need time to adjust to the new influx. Increase your intake slowly over a few weeks rather than overhauling your diet overnight. Soluble fiber, found in oats, oranges, and sweet potatoes, dissolves in water and is generally easier on your system. Starting with more soluble fiber and gradually adding insoluble sources gives your gut microbiome time to adapt without producing excessive gas.
Water and Movement
Drinking enough water supports the entire digestive process and helps prevent constipation, which is a common cause of trapped gas. When stool moves slowly through your colon, bacteria have more time to ferment it, producing more gas that has nowhere to go. If you’re eating a high-fiber diet, adequate water intake is especially important because fiber absorbs water as it moves through your system.
A short walk after meals also helps. Even five minutes of light movement within an hour of eating gets your gastrointestinal tract moving and helps gas transit through more quickly rather than pooling and causing discomfort. This is simple enough to become a daily habit, and it has the added benefit of reducing post-meal blood sugar spikes.
Putting It Together
The most effective approach combines several of these strategies. Swap high-FODMAP fruits and vegetables for gentler alternatives when gas is a problem. Soak beans thoroughly before cooking. Add fiber to your diet in small increments rather than all at once. Drink water with and between meals. Finish meals with ginger tea, peppermint tea, or a few fennel seeds. And take a short walk afterward. None of these changes are dramatic on their own, but together they address the most common reasons gas builds up in the first place.
