10 Foods That Are Guaranteed to Make You Fart

Farting, while often a source of embarrassment or humor, is a natural bodily function. Certain foods are known to increase gas production and lead to more frequent and voluminous farting.

In this article, we’ll explore ten foods that are notorious for causing significant flatulence. Understanding these foods can help you manage your diet better or prepare for the inevitable if you choose to indulge.

1. Beans

Beans are a well-known culprit in the world of fart-inducing foods. They contain high levels of oligosaccharides, a type of sugar that the human body cannot fully break down. As these sugars reach the large intestine, bacteria feast on them, producing gas as a by-product.

2. Dairy Products

For those who are lactose intolerant, dairy products can lead to excessive gas. Lactose, the sugar found in milk and dairy products, requires the enzyme lactase for digestion. People with lactose intolerance lack enough lactase, leading to fermentation of lactose in the gut and resultant gas.

3. Cruciferous Vegetables

Vegetables like broccoli, cauliflower, and Brussels sprouts are high in fiber and raffinose. The human digestive system struggles to break down raffinose, leading to fermentation in the gut and the production of gas.

4. Carbonated Beverages

Drinks like soda and sparkling water introduce carbon dioxide into the digestive system. Not all of this gas is released by burping, and the remainder can accumulate in the gut, causing farting.

5. Onions

Onions contain fructose, which is another type of sugar that can ferment in the large intestine. This fermentation produces gas, contributing to more farting.

6. Garlic

Similar to onions, garlic contains fructans, which are fermentable carbohydrates that can lead to increased gas production in the gut.

7. Whole Grains

Whole grains, such as wheat and barley, are rich in fiber, raffinose, and starch. All of these can ferment in the large intestine, leading to gas production.

8. Artificial Sweeteners

Artificial sweeteners like sorbitol and xylitol are not fully absorbed by the body and get fermented by bacteria in the large intestine, leading to gas and bloating.

9. Processed Foods

Processed foods often contain various additives, sugars, and lactose, which can increase gas production in the digestive tract.

10. Legumes

Other legumes like lentils and chickpeas contain high levels of oligosaccharides and fiber, making them common gas-producing foods.


While farting is a natural process, excessive gas can be uncomfortable and embarrassing. Understanding how certain foods impact your digestive system can help in managing your diet for better gut health. Remember, everyone’s body reacts differently, so it’s essential to observe how your body responds to these foods.
