Why are bananas generally good for an upset gut?
Bananas have long been considered a go-to food for an unsettled stomach, and for good reason. They are easy on the digestive system and packed with nutrients that can help with various gastrointestinal issues. Their bland nature and soft texture make them an ideal choice when your system is feeling sensitive.
Easing gastrointestinal distress
- Easy to Digest: Bananas are relatively low in fiber and fat, making them less demanding for your digestive system to process compared to other foods. This allows your gut to rest and recover, especially after bouts of diarrhea or vomiting.
- Soothes Stomach Lining: According to MedlinePlus, bananas can help relieve an upset stomach by stimulating the production of mucus from the stomach lining. This mucus creates a protective barrier against the stomach's acidic contents, which can help alleviate heartburn and other irritation.
- Contains Pectin: The fruit contains pectin, a soluble fiber that absorbs excess water in the intestines. This helps to bulk up and solidify stool, which can reduce the frequency and severity of diarrhea.
Restoring electrolytes
Vomiting and diarrhea can cause a significant loss of electrolytes, particularly potassium. Bananas are a rich source of potassium, and consuming them helps to replenish this essential mineral, aiding in your body's recovery. A medium banana provides around 320-400 mg of potassium, helping to maintain hydration and proper nerve and muscle function.
Supporting a healthy gut microbiome
Bananas act as a prebiotic, containing fibers like fructooligosaccharides and resistant starch that feed the beneficial bacteria in your gut. A healthy gut microbiome is crucial for overall digestive health and can help speed up recovery from a stomach bug. One study on overweight women who ate bananas twice daily showed a significant increase in beneficial bifidobacteria and a reduction in bloating.
The importance of ripeness
The ripeness of a banana plays a crucial role in its effect on an upset gut. The starch content changes as the fruit matures, which can alter its digestive properties.
Unripe (green) bananas
- Higher Resistant Starch: Unripe bananas contain more resistant starch, which the body cannot digest in the small intestine. This ferments in the large intestine, potentially causing gas and bloating for sensitive individuals.
- Low FODMAP: On the other hand, because they have not fully ripened, unripe bananas are lower in FODMAPs (fermentable sugars), which can be beneficial for some people with IBS.
Ripe (yellow) bananas
- Easy to Digest: Ripe bananas have a higher sugar content and less resistant starch, making them much easier for your body to break down and digest.
- Higher FODMAPs: As bananas ripen, they contain higher levels of FODMAPs, which can trigger symptoms like cramping and gas in those with IBS or fructose intolerance.
Potential downsides and when to avoid bananas
While bananas are generally considered safe, they can pose problems for certain individuals or when consumed improperly.
- Food sensitivities: If you are sensitive to FODMAPs or have fructose malabsorption, ripe bananas can increase gas, bloating, and cramping. Limiting or avoiding them may be necessary.
- Sorbitol sensitivity: Bananas contain sorbitol, a sugar alcohol that can cause digestive issues if you consume too many at once.
- Banana allergy: Although rare, some individuals have an allergy to bananas. This is often linked to a latex allergy due to similar protein structures. Symptoms can range from hives to severe gastrointestinal distress.
- Empty stomach: Some people report stomach cramps or discomfort from eating bananas on an empty stomach, so it is often recommended to consume them after a meal.
Banana ripeness comparison
| Feature | Unripe (Green) Banana | Ripe (Yellow) Banana |
|---|---|---|
| Starch Content | High in resistant starch | Lower in resistant starch |
| Sugar Content | Low | High |
| Digestibility | Can be harder to digest | Easy to digest |
| Prebiotic Effect | Provides food for gut bacteria via resistant starch | Also contains prebiotic fiber, such as inulin, but less resistant starch |
| Best for | Those on a low-FODMAP diet who can tolerate resistant starch | Most people seeking gentle, bland food for an upset stomach |
| Potential Downside | May cause gas and bloating for some sensitive individuals | Can trigger symptoms in those with high-FODMAP sensitivities |
What to eat for an upset stomach beyond bananas
While bananas are a great option, a balanced approach is best. Incorporate other bland, easily digestible foods to ensure adequate nutrition and hydration while your stomach recovers.
- The Bland Diet: A less restrictive version of the BRAT diet includes a wider variety of foods that are gentle on the digestive system.
- Low-Fiber Starches: Plain rice, saltine crackers, and toast are staples that can help absorb stomach acids.
- Lean Protein: Skinless baked chicken or turkey and scrambled eggs are low-fat protein options.
- Probiotic-Rich Foods: Plain, low-fat yogurt or kefir can help re-establish healthy gut bacteria, but avoid if lactose intolerance is an issue.
- Hydration is Key: Replenish fluids with clear broths, diluted fruit juice, herbal teas, or oral rehydration solutions. Avoid overly sugary drinks and caffeine.
Conclusion
For most people experiencing digestive distress, ripe bananas are a safe and effective remedy. Their easy digestibility, potassium content for electrolyte balance, and prebiotic fiber for gut bacteria make them an excellent choice for short-term relief. However, individuals with specific sensitivities, like IBS or fructose intolerance, should consider their tolerance and the banana's ripeness. By listening to your body and pairing bananas with a balanced diet of other bland, gut-friendly foods, you can navigate an upset stomach with confidence.

Key takeaways
Soothing Gut: Ripe bananas are easy to digest and have an antacid effect that helps soothe an upset stomach and relieve indigestion. Restores Electrolytes: High in potassium, bananas help replenish vital electrolytes lost during vomiting or diarrhea. Boosts Gut Bacteria: As a prebiotic, the fiber in bananas feeds beneficial gut bacteria, promoting a healthy microbiome. Ripeness Matters: Opt for ripe, yellow bananas during stomach distress; unripe, green ones contain more resistant starch that can cause gas in some people. Consider Sensitivities: People with IBS or fructose intolerance should be mindful, as ripe bananas can be high in FODMAPs and cause discomfort.
FAQs
Can bananas cause bloating with an upset gut? Yes, unripe green bananas can cause bloating due to their high content of resistant starch, which ferments in the gut and produces gas. Ripe bananas may also cause bloating in individuals with high-FODMAP sensitivity.
Is the BRAT diet still recommended for an upset gut? While the BRAT diet (Bananas, Rice, Applesauce, Toast) is still used for short-term relief, many healthcare professionals now recommend a broader bland diet for better nutrition during recovery.
How many bananas should I eat for an upset stomach? Begin with one or two ripe bananas per day and monitor how your stomach reacts. Overeating can increase sugar and fiber intake, potentially causing further discomfort.
Can I eat bananas for constipation? Yes, ripe bananas contain pectin, a soluble fiber that can help soften stool and support regular bowel movements. However, unripe bananas have resistant starch that can potentially worsen constipation.
Are bananas okay for acid reflux? Yes, ripe bananas have a naturally low pH and can help coat the stomach lining, which may provide relief from acid reflux and heartburn.
Should I eat bananas on an empty stomach? For an upset stomach, some people find eating bananas on an empty stomach can lead to discomfort, so it's often recommended to eat them after a meal.
When should I avoid bananas with an upset stomach? Avoid bananas if you have a known allergy or severe digestive issues like IBS or fructose intolerance where ripe bananas are a trigger. Unripe bananas should be avoided if you have a sensitive stomach.
