This can be attributed to several factors like swallowing the gas while eating food in a hurry or to the breaking of undigested foods in the large intestine by the bacteria.

Now let us focus on the foods that can cause gas in the stomach.


Avoiding onions to a certain extent can cause the reduced formation of gas in your tummy. Want to know why? Onions contain a group of sugars like fructose that cannot be well absorbed in the small intestine.

As a result, when they are passed on to the large intestine, the formation of gas takes place and it can screw the process of digestion.

Starchy Foods:

Consuming starchy foods like rice, pasta and bread can be the real culprit for the collection of gas in your intestinal tract. Want to know why?

These kinds of foods are broken down into sugar quickly and they may not be absorbed well in the small intestine. As a result, they may make their way to the large intestine where they are broken down into gas-producing bacteria.


Cauliflower can be the other culprit! It is a cruciferous vegetable. By cruciferous we mean it belongs to the family of Brassicaceae which causes flatulence, that is the formation of gas.

Being rich in sulfur compounds and oligosaccharides, it causes a bad smelling gas to be released when consumed in large amounts.

Whole Grains:

Whole grains though good for health, care should be taken as to not consume them in large amounts in a single helping. Some of the whole grains include wheat and oats.

They contain large quantities of fibre which are very difficult to be digested in the small intestine. All of these grains are broken down only in the large intestine which leads to flatulence.

Dairy Products:

The lactose present in the dairy products can cause real trouble to the stomach. Let us see why!

First of all, what is lactose? It is a type of sugar found in milk and almost all dairy products. Lactase is an enzyme which is needed to digest this kind of sugar.

Some people suffer from insufficient lactase production resulting in the development of lactose intolerance, the side effect of which being the gas formation and bloating.

People diagnosed with lactose intolerance can take a lactase tablet before consuming any dairy product which has lactose present in it.


Lentils, otherwise called legumes, are rich in fibre content, proteins, carbohydrates and minerals. People who are sensitive to eating fibre content, in other words, those of who are not used to eating a lot of fibre-dense foods can be the victim of flatulence on consuming lentils.

They also contain certain sugars which are very difficult to get digested resulting in excess gas production. However, soaking them overnight and consuming the sprouted lentils, can solve this problem.

Carbonated Drinks:

Carbonated beverages can cause gas production in your digestive tract. Let us see how! The first reason might be attributed to its carbonation, which easily causes the stomach lining to get irritated.

Secondly, fructose is the other culprit which results in the excessive formation of gas.
