What to Eat When You Have Diarrhea: 9 Best Foods (& Meal Plan)

Updated in February 2024

When you have diarrhea, you should prioritize food with soluble fiber, like white bread, white rice and white pasta. You should also look to include lean meats (like chicken a fish) and fruits without the peel (as the peel can be hard to digest) into your diet, as these foods can help with digestion, reduce bowel movements and help with abdominal pain. 

In the meantime, to manage pain and loose stools, you should avoid eating processed foods and fatty foods, like premade sauces, fried food, cured meat, milk and dairy products. You should also avoid eating foods that can increase gas production, like beans, chickpeas, broccoli and fizzy drinks. 

Lots of fluid is lost through diarrhea, and therefore it is essential to increase your fluid intake by drinking water, tea and coconut water. This can help to replace any lost electrolytes and prevent dehydration.

Foods to eat

The best foods to eat when you have diarrhea include:

1. Peeled apples

Peeled apples, raw or cooked, are a great option to include in your diet when you have diarrhea. These are low in insoluble fiber, a type of fiber that tends to speed up bowel movements through the intestines.

It is important to always consume fruits without their peel, seeds and pulp when possible as these are the parts of fruit with the highest amounts of insoluble fiber are found.

2. Potatoes

Potatoes are a tuber that are low in fiber and are easy to digest, which can help to prevent diarrhea flareups. It is important to eat potatoes without their peel and in low-fat preparations, such as mashed potatoes, roasts or stews.

3. Unripe bananas

Unripe bananas have a great amount of soluble fiber, a type of fiber that helps control involuntary bowel movements. This type of fiber also balances the health of the intestinal flora, helping to control diarrhea. Green bananas can be consumed raw or cooked.

4. Fish

Fish, especially those with white meat, such as sole, hake, cod or sea bass, are low in fat and can therefore help to prevent diarrhea

In addition, fish and other lean proteins such as chicken, eggs, tofu, white cheese and lean cuts of beef, are also essential for boosting immunity and preventing muscle losses.

5. Peeled guava

Peeled guava can be consumed during diarrhea, as it has low amounts of insoluble fiber. Learn more about the benefits of guava and how to consume it.

Other fruits that can also be consumed without the peel are cashews, passion fruit, peaches and lemons.

6. White rice

Because it is low in fiber, white rice is a recommended food to include in your diet when you have diarrhea.

In addition to white rice, other grains that are also low in fiber that you can consume are cornmeal, white bread, white pasta, toast and crackers.

7. Boiled carrots

Cooked, peeled carrots can be consumed when you have diarrhea, as they are lower in fiber than raw carrots with their peel. Carrots also have pectin, a type of fiber that helps prolong digestion time and reduce bowel movements.

Other vegetables that can also be consumed are zucchini, chayote, potatoes, yams, carrots, pumpkin, eggplant and green beans.

8. Coconut water

Coconut water is recommended to help treat diarrhea, because it helps replenish potassium and sodium levels. These are essential nutrients for maintaining bodily functions, and tend to be eliminated in large quantities during diarrhea flare-ups.

9. Peeled pears

Peeled pears, which can be consumed raw or cooked, can help to treat diarrhea because it is high in soluble fiber that reduces the speed of intestinal transit and regulates the volume of feces. Furthermore, pears are rich in water, helping to hydrate the body.

How to start

You should ideally start with consuming a liquid diet, made-up of homemade broths or soups, liquefied and strained juices made from apples, pear or peaches. You can also eat gelatin, and drink rice water or chamomile, bay leaf or guava teas.

Once the liquid diet is tolerated, you can progress your diet to easily digestible foods such as white rice, rice noodles, pasta, polenta, peeled potatoes, mashed potatoes, cooked carrots, chayote or zucchini. Veggies should be fresh and cooked and still warm to promote digestion. These carbohydrates can be served with eggs, skinless chicken or shredded fish.

It is also possible to consume white bread, rice or corn biscuits, cream crackers, unripe bananas, apples, pears, peaches and peeled guava, as well as low-fat white cheeses, such as ricotta or cream cheese.

Then, depending on tolerance, you can progress your diet to include your usual foods.

Treatment may involve the use of a prescription antibiotics.
