In this brief article, we are going to answer the question “Do bananas help with diarrhea?” and see some symptoms of diarrhea and how bananas can be included in a diet after a diarrhea episode.  

Do bananas help with diarrhea?

Bananas can help during a diarrhea event, for sure! Bananas are rich in potassium, soluble fibers, and are a good source of energy, and help to keep the intestinal fluids lost during diarrhea. Bananas are a very good food to eat to get the intestine health back to normal, also because this fruit contains pectin. Besides the nutritional facts, bananas are easy to take, they can be found easily and it is popular in different cultures. 

Episodes of diarrhea are when there is the necessity to go to the bathroom more than three times per day with the presence of liquid stools. But, if you hydrate correctly and take some care with your food, the recovery will be so much faster. This disease will usually pass in two or three days, if certain care is taken, and you can get better, with simple measures and home treatments.

An adult can have diarrhea many times during life, for many different reasons. Among these reasons can be: an unbalanced diet, intoxication by a portion of different food, intoxication due to contaminated/spoiled food, food allergy, excessive alcohol consumption, and even emotional issues.

When diarrhea events occur, the intestine will be very sensitive and irritated, with low absorption of nutrients and very low water absorption. The worst-case scenario for a person who has diarrhea is the experience of dehydration. So, it is important to be focused on the alimentation and also on hydration during this period.

How do bananas help in diarrhea?

When suffering from diarrhea, the body loses large amounts of water. But, water is not the only one lost during these episodes, the body also loses mineral salts important for the proper functioning of the body, such as potassium. 

One of the most important components present in bananas is potassium. In addition, to be a mineral salt, potassium helps prevent cramps, is important for muscle fibers, and helps control blood pressure levels. 

A banana of approximately 100g, can contain more than 300mg of potassium, which is more than 10% of the amount of the mineral recommended for daily consumption.

In addition, it is possible to find fiber and pectin in bananas, both of which help the proper functioning of the intestine and prevent further loss of water. Speaking of dietary fiber, there are two types of fiber in food, soluble and insoluble.

Unlike insoluble fibers that help with going to the bathroom, such as those found in pineapple, mango, and papaya, soluble fiber – which can cause some constipation – present in bananas. What is interesting in cases of diarrhea events. Bananas can have more than 2.5 g of fiber/fruit.

What not to eat when recovering from diarrhea?

It is recommended to avoid foods that can cause even more irritation and no foods that cause you to have more diarrhea, so it is very important to drink plenty of water.

As there is the presence of liquid stools, none of the liquids we ingest will be well absorbed in the intestine.

So you have to be hydrated all the time, so you can get a good recovery – it could be water, it could be coconut water or tea without caffeine.

Another important point is to reduce the consumption of insoluble fibers, as the fibers present in salads, whole foods can make the intestines work even more, so it is recommended to eat white rice and cooked potatoes, vegetables, and cooked fruits, and avoid eating raw foods.

When you have diarrhea, you likely have more difficulty digesting lactose as if it were a momentary intolerance, so it is not recommended to consume dairy foods and foods with more fat, in addition to no sausages, no fried foods, no alcoholic beverages.

Once you get feeling better and have more appetite is when you will be recovering from diarrhea and getting better… but pay attention, even after you no longer have sick symptoms it is important to keep at least 2 light and ‘sick’ meals a day.

If the diarrhea is not improving after three days and if, in addition to diarrhea, you have symptoms of fever or even blood in your stools, it is recommended to see a doctor, especially for the elderly, pregnant women, or babies.
