Foods that cause gas, like eggs, bananas and sweet potato, for example are rich in fiber and carbohydrates, which are fermented by intestinal flora during digestion. These types of nutrients take longer to digest, leading to longer fermentation times and a higher flatulence and bloating, which can vary from person to person.

Cauliflower, broccoli and cabbage, are also foods that cause gas and contribute to smelly farts. These specific foods contain glucosinolates, a phytonutrient that contains sulfur and give gas a strong, foul odor.

The specific foods that cause gas can vary from person to person. If you experience excessive gas after eating, especially after eating certain foods, you are advised to see a doctor or registered dietitian to help manage any discomfort, and to develop a diet or eating plan that meets your health goals while reducing symptoms.

List of gassy foods

The main foods that can cause gas include:

1. Egg

The sulfur in eggs can cause gas, as this compound favors the formation of intestinal gas in some people. Sulfur also gives gas a foul odor.

2. Banana

Bananas can cause gas in some people, as this fruit is rich in soluble fiber. This type of fiber is not easily digested in the intestine, which can lead to the formation of gas.

Bananas also contain fructose, a natural sugar present in fruits that can cause abdominal bloating and excess gas. These symptoms are especially prone to happen in fructose is consumed in excess or consumed by people with irritable bowel syndrome.

3. Sweet potato

Sweet potatoes can cause gas because they are a rich in starch. Starch is a type of carbohydrate that is digested very slowly, which can lead to the production of more gas in the large intestine. Learn more about the symptoms of gas and how they can present.

4. Beans

Beans and other legumes in general are known to cause intestinal gas. They are rich in fiber and starch like rafinose, that are harder to digest, leading to longer fermentation time in the colon and increased gas production.

There are many ways you can reduce gas produced by beans, like allowing them to soak for 12 hours before cooking and ensuring they are thoroughly cooked before serving.

5. Cauliflower

Cauliflower can cause gas, because this vegetable is rich in raffinose. This is a type of carbohydrate that is not immediately absorbed by the body. It is fermented in the gut by intestinal bacteria, leading to symptoms such as abdominal swelling and discomfort.

Cauliflower also contains glucosinolates, a phytonutrient that contains sulfur. This compound can lead to foul-smelling gas.

6. Milk

Milk can cause gas in people with a lactose intolerance or sensitivity. This condition is characterized by a lack or reduce amount of lactase enzymes, and therefore undigested lactose sugars are digested by gut bacteria. This leads to the release of hydrogen and short-chain fatty acids, which produce gas.

In these cases, milk and dairy products can be replaced with lactose-free versions or plant-based milk, such as almond and soy milk.

7. Oats

Oats and other whole grains, such as brown rice and corn, can cause gas because they are rich in fiber, raffinose and starch. These favor the formation of gas in the intestine during digestion.

8. Chickpeas

Chickpeas can cause intestinal gas, as this legume contains good amounts of resistant starches such as raffinose and stachyose that are not digested by the body and are fermented by intestinal bacteria that produce excess gas.

9. Cabbage

Cabbage is rich in raffinose, a type of carbohydrate that can cause gas when metabolized in the intestine. Like eggs, cabbage is also high in sulfur, a compound that leads to foul-smelling gas.

10. Broccoli

Broccoli can cause gas because it is rich in raffinose, a type of carbohydrate that is fermented by intestinal bacteria.

11. Onion

Onions contain fructose, raffinose and sorbitol, compounds that are digested and fermented by gut bacteria and naturally produce gas.

12. Soda

Soft drinks, sparkling water, beer and other carbonated drinks, facilitate air entry into the intestines, causing stomach and intestinal gas. Opt instead for water and teas that naturally reduce bloating.

How to get rid of gas

Some tips for eliminating gas naturally include:

Avoid the consumption of candy and gum, as they encourage the ingestion of air which can lead to abdominal discomfort and gas and
Reduce your intake of foods that cause gas
Avoid the consumption of milk and dairy products if you have been diagnosed with a lactose intolerance;
Chew food well.

Additionally, drinking some teas, such as fennel, cardamom and ginger, can also help eliminate excess gas. Check out other home remedies for gas and how to prepare them.
