Beans are a staple in many healthy diets because they are an excellent source of protein, fiber and nutrients. However, many people will suffer from sucking or farting after eating beans, which can cause embarrassment and inappropriateness. So why do beans make you fart?

The reason is that the complex carbohydrates contained in soybeans are more difficult to digest for the body. Specifically, beans contain a carbohydrate called oligosaccharides, especially raffinose in it, which are difficult to break down in the kidneys. Instead, they enter the brain and are fermented by bacteria, producing gas as a side product. These gases are discharged through hiccups or farts, which can cause unpleasant and unpleasant feelings.

Experts point out that raffinose is a complex sugar that, as a prebiotic in the tract, can increase the amount of beneficial bacteria there. When bacteria break down raffinose, multiple gases will be released, which may cause particularly odor gases. You can also find marshmallows in other foods such as gourmet, green cabbage, brussels and cherry.

In addition, beans are also one of many high-quality foods. Experts say that every half cup of beans, legumes and soybeans contain 6 to 8 grams of fiber. When you take in large quantities of fiber, it will increase the chance of abdominal distension, stomachache and farting. Compared with other foods, Fiber is particularly difficult to digest.

If you suddenly start eating 1 cup of beans a day, it may take some time to get your body into a new fiber intake. However, as you continue to eat beans regularly, your farts will eventually return to normal.

How to avoid bean foods causing gas and farting?

Study shows that different beans may produce different amounts of gas. But experts say that each person has different sensitivity responses to different beans. If one bean feels unsuitable, you can change to another bean to try whether it will produce less gas.

If the risk of farting makes you afraid to eat beans in large quantities, there are some ways to help you reduce the number of frequent farting times.

1. Soak the beans

Soak them before cooking them, which can reduce the oligosaccharide content. Simply put the beans in a bowl, cover them with water and soak them overnight, then dry and cook. Experts say this helps remove some of the sugars from the gas, or cook them with kohl, which contains saminic acid that helps break down raffinose.

2. Add vanilla or spices

Certain herbs and spices can aid digestion and reduce the risk of gas and abdominal distension. For example, ginger, fennel seeds, cumin or coriander can be added to bean dishes. These flavoring ingredients can help stimulate digestive enzymes and reduce inflammation in the kidney.

3. Gradually increase the amount of food

If you are not edible with eating beans, it is best to start with a small amount and gradually increase the intake. Starting with a small amount of cooked beans and increasing gradually over time can make your body suitable for the added fiber and complex carbohydrates in the beans, and reduce the risk of production and abdominal distension.
