Bananas for Diarrhea: How Does it Work?

Bananas are known to have medicinal properties in abundance. It contains a rare combination of vitamins, minerals, and proteins. The fruit is also universally recognized as a source of energy.

Raw bananas are equally beneficial for diarrhea. The Pectin in the raw banana absorbs the excess water and protects the lining of the stomach.

On a daily basis, a large amount of water is secreted into the lumen of the small intestine, which in return is absorbed by the body before it reaches the large intestine. However, with the onset of diarrhea, the water secreted is much more than the water absorbed by the body. This is the reason why the stool runs watery. To alleviate diarrhea, the absorption of excess water is crucial.

Unripe or green bananas have a natural fibrous starch called pectin(2). This is not digested in the small intestine and is passed onto the colon, which is further fermented by bacteria into short chains of fatty acid. These short chains of fatty acids help in the stimulation of the absorption of the salt and water, making the stool firm and thick.

Pectin is also known to stimulate the production of mucus in the colon and small bowel, which serves as a barrier between the stomach lining and the acidic gastric substances, which generally upsets the stomach.

Banana and Diarrhea

Bananas provide the much-needed energy without adding any fat to the body or causing a risk of increasing cholesterol.

There are three types of natural sugars found in a banana. Glucose, sucrose, and fructose are the natural sugars that are found in a banana. They are responsible for providing energy and reducing the chances of high cholesterol and the consumption of fat.

Soluble and insoluble fibers play a crucial role in an individual’s health. A disruption in the balance of fibers in the stomach leads to infections. Bananas for diarrhea helps in keeping the gut healthy and safe from the harmful parasites, bacteria, and viruses that may upset the pH level of the stomach.
