How Do Bananas Help With Constipation?

Constipation is a condition characterized by irregular bowel movements. It makes the stool hard to pass. It can be triggered by various factors like a poor diet or a sedentary lifestyle (lack of exercise).

Bananas are often associated with relieving bowel conditions like constipation. This is mainly because they are rich sources of fiber. Fiber-rich foods have shown to help combat constipation (1).

Fiber is believed to promote absorption of water, thereby making the stool soft and easy to pass through the digestive tract.

Wondering how much fiber is present in bananas? Let’s find out.

How Much Fiber Does A Banana Have?

A medium-sized banana contains about 3.1 grams of fiber (1). This makes it a wonderful addition to a high-fiber diet.

While there are many claims that fiber can help treat constipation, some studies claim that bananas or other fiber-rich foods may have a reverse effect and can trigger constipation. What do bananas actually do? Do they help constipation or trigger it?

Do Bananas Make You Constipated Or Poop?

Some evidence hints that bananas help relieve constipation. However, some people believe that bananas make them constipated. How do you determine whether you should consume bananas or not?

Let’s look at a few facts.

Green banana is a rich source of resistant starch, which contains fiber-like proteins. It helps promote digestive health and metabolism as it is great for your gut flora (2). The resistant starch acts like fiber and can help in relieving constipation. In some cases, green or unripe bananas have also been noted to help with symptoms of diarrhea (3).

On the other hand, in a study, bananas were found to cause constipation. 29-48% of the respondents who took part in the survey considered bananas as constipating (4).

Hence, whether bananas make you constipated or poop depends on your individual constitution.

If bananas help in reducing constipation in your case, here are a few popular remedies you can try.

Though many health professionals associate high-fiber intake with constipation relief, there is no sufficient evidence that proves bananas or fiber-rich foods actually help relieve constipation.

At the end of the day, the impact of banana intake is different for different individuals. Try having a banana the next time you feel constipated to see whether it works for you or not. If it does, great. If it doesn’t, consume fewer bananas or eradicate them completely from your diet to see if that helps.
