Do Peanut and its Butter Cause Gas and Bloating?


Peanuts and their butter are very popular around the world. People appreciate them for their taste and numerous health benefits. However, many people want to know whether these nuts (they are not true nuts, but legumes) and their butter cause gas or not. Perhaps they got bloated after eating one of them, and are not entirely sure whether to continue with their consumption.

Well, this post was created to answer your questions. But before we do that, let’s look at the possible things that can cause gas and bloating in our body system.

Causes of gas

  • Gas is normally produced in our stomach due to the action of acids during digestion. The gas here is usually carbon dioxide.
  • The bacteria that live in our gut can also cause the production of a lot of gas. Usually, they are always involved when it comes to excess gas production.
  • The consumption of high fiber foods is one of the major causes of gas, because fiber doesn’t get digested in the small intestine. Instead, it moves into the large intestine, where bacteria would have to act upon it, thereby causing the production of a lot of gas.
  • Apart from fiber rich foods, intake of FODMAPs can cause the production of a lot of gas in the intestines. FODMAPs are short chain carbohydrates that are poorly absorbed in the small intestine (1). Examples include fructans, lactose, and polyols. FODMAPs are known to also cause certain digestion discomfort in some people.


Do peanuts cause gas?

On a normal basis, eating small amounts of peanuts shouldn’t cause you gas. But when you consume these legumes in large amounts, then it becomes highly likely that they will make you gassy.

Peanut butter on the other hand rarely causes gas, but when it does, it is believed that it is due to peanut better intolerance, or an underlying digestive disorder such as irritable bowel syndrome. Also, peanut butter contains transfatty acids which can cause inflammation in the gut. A process that can lead to gas and bloating.

Peanuts actually cause gas when eaten in large amounts due to the high amount of fiber it contains. Fiber doesn’t digest easily in the human gut. Normally, bacteria will have to act upon it before it gets broken down. And in so doing, a lot of gas is produced.

Apart from fiber, peanuts contain phytate or phytic acid. Most nutritionists believe that phytates are a bit hard to digest, and can often lead to digestive disorders with symptoms such as gas production and bloating.


While peanuts can cause gas, consuming them in only small amounts can help you stay clear of excess gas and bloating. On the other hand, peanut butter can also cause gas, but that differs from one person to another. If you are intolerant to peanut butter, then it’s likely you will become bloated after its consumption.

Finally, you should note that foods cause gas differently in human beings. This means that what causes gas in “Mr A” may not cause gas in “Mr B”, and vice versa.
