Understanding the BRAT Diet Connection
For decades, the BRAT diet—Bananas, Rice, Applesauce, and Toast—has been a go-to remedy for digestive upset, particularly for children. The reason for its effectiveness lies in the properties of these bland, low-fiber foods. Bananas, in particular, are a cornerstone of this diet for several reasons, including their unique composition of soluble fiber and essential nutrients.
How Bananas Act as a Digestive Aid
The benefit of bananas during an episode of diarrhea, or a 'running tummy,' comes down to their specific nutritional makeup.
Binding and Bulking: The fruit contains pectin, a type of soluble fiber that absorbs excess water in the intestines. This process helps to bulk up and firm the stool, which can reduce the frequency and watery consistency of diarrhea.
Electrolyte Replacement: A 'running tummy' can lead to the significant loss of essential electrolytes like potassium. Bananas are a rich source of potassium, helping to replenish what the body loses and preventing dehydration.
Prebiotic Support: Bananas, especially unripe ones, contain prebiotic fibers like inulin and resistant starch. These act as fuel for the beneficial bacteria in your gut, helping to restore a healthy gut microbiome, which can be disrupted during a digestive illness.
Gentle on the Stomach: The soft, easily digestible texture of a ripe banana makes it a safe and soothing food choice when the digestive system is irritated. Its bland flavor also helps to prevent further upset.
The Importance of Banana Ripeness
The ripeness of the banana plays a crucial role in its effect on the digestive system. Unripe (green) bananas contain higher levels of resistant starch and prebiotics, which are excellent for feeding good gut bacteria and can aid in firming stool. Ripe (yellow) bananas contain more simple sugars and less resistant starch, making them a source of easily digestible energy. While both can be beneficial, opting for a slightly less ripe banana might provide a more binding effect.
Comparison: Bananas vs. Other Stomach-Friendly Foods
| Food Item | Primary Benefit for Digestion | Key Component | Best For | Potential Drawbacks |
|---|---|---|---|---|
| Bananas | Replenishes potassium, bulks stool with pectin. | Pectin, Potassium | Diarrhea, electrolyte loss | Can be high in FODMAPs when ripe |
| White Rice | Low-fiber, easily digestible carbohydrate. | Carbohydrates | Gentle energy source, bulking | Minimal nutritional value compared to bananas |
| Applesauce | Pectin content helps bind stool. | Pectin | Soothing, easy to digest | Some commercial varieties contain high sugar |
| Toast | Bland, low-fiber carbohydrate. | Carbohydrates | Gentle energy, binding effect | Can be high in FODMAPs depending on type |
| Yogurt (Probiotic) | Restores good gut bacteria. | Probiotics | Post-diarrhea gut health | Not suitable during active diarrhea due to dairy content |
| Broth | Hydration and electrolyte replacement. | Sodium, Electrolytes | Dehydration, general weakness | Lacks solid food to help bind stools |
Potential Downsides and Considerations
While bananas are generally beneficial for a running tummy, they are not a cure-all, and some individuals may experience issues. Overconsuming very ripe bananas can lead to gas and bloating for some people due to the soluble fiber content and natural sugars. Additionally, individuals with Irritable Bowel Syndrome (IBS) or fructose intolerance should be mindful of their intake, as ripe bananas are high in FODMAPs, which can trigger symptoms.
For a full list of FODMAPs, refer to resources like the Monash University FODMAP Diet. It is important to listen to your body and adjust your intake accordingly.
When to Avoid Bananas for an Upset Stomach
- Fructose Intolerance: If you have difficulty absorbing fructose, ripe bananas, which contain higher levels of this sugar, could worsen your symptoms.
- Existing IBS Symptoms: Since ripe bananas are high in FODMAPs, they might trigger symptoms like cramping and gas in individuals with IBS.
- Latex-Fruit Syndrome: A rare cross-reactivity between banana proteins and latex can cause an allergic reaction.
Conclusion: The Final Verdict
In most cases, yes, a banana is good for a running tummy. Its combination of binding pectin, essential potassium, and prebiotic fibers makes it an excellent choice for soothing diarrhea, replenishing lost nutrients, and supporting overall gut recovery. The bland nature and soft texture also make it easy for an irritated digestive system to tolerate. However, paying attention to the ripeness of the banana and your body's individual sensitivities is key to maximizing its benefits and avoiding potential discomfort.

How to Incorporate Bananas for a Running Tummy
Here are a few ways to add bananas to your diet when dealing with digestive issues:
- Eat a plain, ripe banana as a simple snack.
- Mash a banana and mix it with a small portion of white rice.
- Add a sliced banana to plain, unsweetened applesauce.
- Blend a banana into a simple smoothie with water or electrolyte-fortified water.
Listen to your body and start with small portions to see how you react. Gradually increase your intake as your symptoms improve.
