8 Gas-producing Foods
Foods that cause gas, such as beans and broccoli, for example, have a large amount of fiber and carbohydrates that are fermented by the intestinal flora during digestion, causing flatulence and bloating.
It is important to emphasize that intestinal intolerance to these foods varies from person to person. For this reason, a nutritionist should be consulted for an evaluation to identify which foods cause gas and to make a nutritional plan tailored to the person’s needs.
It will not always be necessary to remove this type of food from the diet, because many times by simply reducing the amount and frequency with which they are ingested, the body is able to tolerate them and reduce the production of gases.
1. Beans
Beans and legumes in general are known to cause intestinal gas. This occurs because they are naturally rich in fiber and resistant starches such as raffinose, which are not digested by the body, so they are fermented by bacteria in the colon producing flatulence.
There are some techniques that could help to reduce the gas produced by consuming beans, such as soaking them for 12h, for example.
Learn about other strategies to keep beans from causing gas.
2. Vegetables
Some vegetables such as broccoli, cabbage, Brussels sprouts, cauliflower, onions, garlic and asparagus can cause excess gas. This occurs because, like beans, they are rich in fiber and have raffinose that is not digested and is fermented in the intestine.
3. Fruits
Fruits, some vegetables and certain products such as pasteurized juices, for example, contain a type of sugar called fructose, the concentration of which varies from one food to another. This type of sugar is not completely absorbed at the intestinal level, so it can favor an increase in gas production. See which fruits have the highest fructose content.
In addition to this, fruits such as apples, peaches, pears and plums also contain soluble fiber that can cause flatulence in some people.
4. Milk and its derivatives
Lactose is the sugar present in milk and its derivatives. When a person is lactose intolerant, it is because his or her body does not contain enough lactase, an enzyme that digests this sugar in the intestine. When it is not digested, it serves as a substrate for intestinal bacteria, which release hydrogen and short-chain fatty acids producing flatulence.
In these cases, it is possible to try consuming lactose-free dairy products or vegetable drinks such as almond milk, for example. In addition, it is important to check the nutritional labeling, as some products may contain lactose among their ingredients.

5. Chewing gum
Chewing gum or eating candy promotes the ingestion of air, known as aerophagia, leading to flatulence and intestinal discomfort. In addition to this, some chewing gums or candies may also contain sorbitol, mannitol or xylitol, these are sugars that can cause gas when fermented in the colon.
6. Carbonated beverages
It is important to avoid soft drinks, carbonated waters, sodas, beers and other carbonated beverages, because they favor the entry of air into the intestine and cause gas production. Drinks with straws should also be avoided.
7. Oatmeal
Oatmeal, oat bran or oat flour, as well as some whole grain foods, can cause gas because they are rich in fiber, raffinose and starch, favoring the formation of gas in the intestine.
8. Peas
Peas in addition to containing fructose and fermentable fiber in the intestine, also contain lectins, which have been associated with bloating and flatulence.
