Understanding Why Bananas Are Recommended for Upset Stomachs
Bananas have long been a go-to folk remedy for various digestive issues, and there is science to back this up. Their unique nutritional profile makes them gentle on the digestive system while still providing valuable nutrients, which are often depleted during illness involving vomiting or diarrhea. The primary reasons bananas are considered beneficial for a stomach upset include their natural antacid properties, ease of digestion, and high electrolyte content.
The BRAT Diet Connection
The BRAT diet—Bananas, Rice, Applesauce, Toast—is a well-known therapeutic diet recommended for temporary stomach issues. The components of this diet are all low-fiber, bland, and easy to digest, which helps to settle the digestive system without causing irritation. Bananas are a crucial part of this, providing energy, potassium, and a gentle source of fiber.
Key Nutrients that Aid Digestion
- Potassium: Vomiting and diarrhea can lead to a significant loss of electrolytes, including potassium. A medium banana contains about 422mg of potassium, helping to replenish this vital mineral and restore balance.
- Pectin: This soluble fiber, present in bananas, helps absorb excess liquid in the intestines. This action can firm up stool and alleviate symptoms of diarrhea. As bananas ripen, the soluble fiber content increases, making them even more effective for this purpose.
- Mucus Production: Bananas have been shown to stimulate the production of protective mucus in the stomach lining. This mucus creates a barrier against stomach acid, which can provide relief from heartburn and general stomach upset.
- Prebiotics: Bananas contain fructooligosaccharides (FOS), a type of prebiotic. Prebiotics act as food for the beneficial bacteria (probiotics) in your gut, helping to restore a healthy balance in your gut microbiome after an illness.
How Ripeness Affects Digestibility
The ripeness of a banana significantly alters its composition and, consequently, its effects on your stomach. It is crucial to choose ripe, yellow bananas when dealing with an upset stomach for the most beneficial outcome.
Comparison of Ripe vs. Green Bananas for Digestion
| Feature | Ripe (Yellow) Banana | Green (Unripe) Banana |
|---|---|---|
| Starch | Starch has converted to simple sugars, making it easier to digest. | High in resistant starch, which is difficult for the small intestine to digest. |
| Digestibility | Easily digestible; gentle on a sensitive digestive system. | Can cause gas, bloating, and discomfort due to fermentation of resistant starch in the large intestine. |
| Effect on Stool | Soothes and firms stool, beneficial for diarrhea. | Can worsen constipation due to its high resistant starch and tannins. |
| Flavor | Sweeter and softer. | Less sweet and much firmer. |
Potential Drawbacks and When to Be Cautious
While bananas are safe for most people, certain individuals should exercise caution or avoid them, especially when their stomach is already sensitive.
- Irritable Bowel Syndrome (IBS): For some with IBS, the fermentable carbohydrates (FODMAPs) in bananas can trigger gas and bloating, even when ripe. Unripe bananas are lower in FODMAPs, but ripe bananas are considered high, so those following a low-FODMAP diet should limit their intake.
- Fructose Intolerance: Individuals with this condition may experience discomfort from the fructose in bananas, as their bodies cannot properly absorb and digest it.
- Banana Allergy: While rare, a banana allergy can cause abdominal pain, nausea, and other symptoms. If you have a known allergy, avoid them entirely.
- Latex-Fruit Syndrome: People with a latex allergy can also have cross-reactive allergies to certain foods, including bananas.
Conclusion
In summary, for most people dealing with a general upset stomach, eating a ripe banana can be a safe and effective part of their recovery. They provide easily digestible energy, replenish lost electrolytes, and contain compounds that can soothe and protect the stomach lining. For conditions involving diarrhea, the soluble fiber and pectin can be particularly helpful. However, it is important to be mindful of individual sensitivities, such as IBS or fructose intolerance, and to choose a ripe banana over a green one to avoid potential gas and bloating. If symptoms persist or worsen, consulting a healthcare professional is always the best course of action.
Frequently Asked Questions
How many bananas should I eat with an upset stomach?
Stick to one or two ripe bananas per day. Eating too many can potentially lead to gas or bloating, especially for sensitive individuals.
Are bananas good for nausea?
Yes, bananas are often recommended for nausea. Their bland nature and soft texture make them easy to keep down, and they provide quick energy when appetite is low.
Do bananas cause gas or bloating?
Ripe bananas are generally well-tolerated, but the resistant starch in green, unripe bananas ferments in the large intestine and can cause gas and bloating in some people.
What is the BRAT diet?
The BRAT diet stands for Bananas, Rice, Applesauce, and Toast. This diet consists of bland, low-fiber foods that are gentle on the digestive system and are recommended for those with stomach issues.
Can I eat bananas if I have stomach ulcers?
Yes. The antacid properties of bananas can help neutralize stomach acid and stimulate the production of mucus, which protects the stomach lining and may offer some relief for ulcer sufferers.
Are bananas helpful for constipation?
While bananas contain fiber, the effect on constipation depends on their ripeness. Unripe bananas have resistant starch and tannins that can worsen constipation, while ripe bananas with their soluble fiber (pectin) can help regulate bowel movements.
Can children have bananas for an upset stomach?
Yes, ripe bananas are a staple of the BRAT diet and are often recommended for children experiencing diarrhea or vomiting because they are easy to digest and replace lost electrolytes.

Key Takeaways
- Choose Ripe Bananas: For an upset stomach, always opt for ripe, yellow bananas. The resistant starch in green bananas can be difficult to digest and may cause gas.
- Replenish Electrolytes: Bananas are a great source of potassium, a vital electrolyte often lost through vomiting or diarrhea.
- Support Gut Health: The prebiotics and pectin in bananas feed good gut bacteria and can help restore a healthy microbiome.
- Mindful Consumption: While beneficial for most, individuals with IBS or fructose intolerance should monitor their tolerance to bananas, as they can sometimes cause discomfort.
- Gentle on the Stomach: Bananas are easy to digest and can help soothe the stomach lining by stimulating mucus production, providing relief from heartburn and indigestion.
