Bananas, applesauce, and papaya are among the best fruits for settling an upset stomach, but your ideal choice depends on what’s actually bothering you. Diarrhea, nausea, bloating, and acid reflux each respond better to different fruits, and some popular options can actually make things worse.
Bananas: The Go-To for Most Stomach Trouble
Bananas are one of the most universally tolerated fruits during digestive upset. They’re soft, low in acid, and rich in potassium, which is especially important if you’ve been vomiting or dealing with diarrhea and losing electrolytes. Their natural starch is gentle on an irritated stomach lining, and they require almost no digestive effort.
One thing to know: ripeness matters. A ripe banana with brown spots is higher in fructose, a natural sugar that some people absorb poorly. If you’re prone to bloating or have irritable bowel syndrome, an unripe or just-ripe banana (still slightly firm and yellow) is the safer bet. According to Cleveland Clinic guidelines on low-FODMAP eating, you can have a whole banana if it’s not fully ripe, but should limit yourself to about a third of a ripe one.
Applesauce for Diarrhea
Applesauce has been a staple of the classic BRAT diet (bananas, rice, applesauce, toast) for decades, and for good reason. It contains pectin, a type of soluble fiber that increases the viscosity and volume of stools, helping to firm things up when diarrhea strikes. Cooking apples into applesauce also breaks down the tough cell walls and insoluble fiber that can irritate a sensitive gut.
Stick with unsweetened applesauce. Added sugar can pull water into the intestines and make diarrhea worse. And while applesauce is helpful, raw apples are a different story. They’re high in fructose and insoluble fiber, which can trigger gas and bloating, particularly if your stomach is already unhappy.
Papaya and Pineapple for Bloating
If your upset stomach feels more like heaviness, fullness, or bloating after eating, papaya and pineapple offer something other fruits don’t: natural digestive enzymes that help break down protein.
Papaya contains papain, a protein-digesting enzyme that has been used as a folk remedy for indigestion across tropical cultures. Research confirms papain is a proteolytic enzyme, meaning it actively cleaves protein molecules, which can ease the burden on your stomach when digestion feels sluggish. It’s also been shown to have anti-inflammatory properties.
Pineapple contains bromelain, a similar enzyme complex. Studies show bromelain reduces inflammation in the gut lining, and it has been specifically studied for its ability to lower inflammatory signaling in the intestines. Patients with inflammatory bowel conditions have shown symptomatic improvement with bromelain supplementation. For everyday bloating, eating a few chunks of fresh pineapple with or after a protein-heavy meal can help things move along more comfortably. Canned pineapple in syrup won’t have the same effect since heat during processing destroys much of the enzyme activity.
Watermelon and Cantaloupe for Rehydration
When you’re recovering from a stomach bug, staying hydrated matters as much as what you eat. Watermelon is 92% water and provides 170 milligrams of potassium per cup, making it a natural source of fluids and electrolytes. Cantaloupe is similarly water-rich and provides potassium along with some sodium.
There’s a catch, though. Watermelon is high in fructose, which means it can worsen gas, bloating, and diarrhea in people who absorb fructose poorly, and it’s considered a high-FODMAP fruit. If your stomach upset involves loose stools or you have IBS, watermelon may do more harm than good. In that case, small sips of coconut water or broth are safer hydration choices.
The BRAT Diet Still Works, but It’s Not Enough
The BRAT diet remains a reasonable starting point for the first day or two of acute stomach illness like food poisoning, stomach flu, or traveler’s diarrhea. But current guidance from Harvard Health suggests there’s no need to restrict yourself to just those four foods. Brothy soups, oatmeal, boiled potatoes, crackers, and plain dry cereal are equally easy to digest and provide a wider range of nutrients.
Once your stomach begins to settle, adding cooked squash, skinless sweet potatoes, avocado, and lean proteins like skinless chicken or fish gives your body the protein and calories it needs to actually recover. Staying on the BRAT diet for more than a couple of days can leave you short on essential nutrients at exactly the time your body needs them most.
Fruits That Can Make Things Worse
Not every fruit belongs on your plate when your stomach is off. Some of the most common offenders:
- Oranges, grapefruit, and other citrus. Their high acidity can relax the valve between your esophagus and stomach, worsening acid reflux and heartburn. If nausea or a burning sensation is your main symptom, skip citrus entirely.
- Apples and pears (raw). Both are high in fructose and sorbitol, which are poorly absorbed in many people’s guts. This draws extra water into the intestines and feeds gas-producing bacteria, leading to bloating, cramps, and diarrhea.
- Cherries and stone fruits. Peaches, plums, and cherries contain both fructose and sugar alcohols. They’re considered high-FODMAP and are common triggers for abdominal pain and loose stools.
- Dried fruit. Concentrating fruit into dried form also concentrates the sugars and fiber. A handful of dried apricots or figs delivers a much larger dose of fermentable carbohydrates than the same amount of fresh fruit, which can quickly overwhelm a sensitive digestive system.
Low-FODMAP Fruits for Sensitive Stomachs
If your upset stomach is a recurring problem, particularly if you’ve been diagnosed with or suspect IBS, choosing low-FODMAP fruits can help you eat fruit without triggering symptoms. Grapes, strawberries, pineapple, kiwi, and unripe bananas are all considered safe options. These fruits contain lower levels of the fermentable sugars that pull water into the gut and produce gas.
Portion size still matters on a low-FODMAP plan. Even a low-FODMAP fruit can cause trouble if you eat a large amount in one sitting, since the total fructose load adds up. Spreading fruit intake across the day in small portions is a more reliable strategy than eating a big bowl of berries at once.
Cooked Fruit Is Easier to Digest
When your stomach is at its worst, how you prepare fruit matters almost as much as which fruit you choose. Cooking breaks down insoluble fiber, the rough, scratchy type that can irritate an inflamed gut lining. Heat also softens cell walls and changes the texture, making fruit physically easier to chew and digest.
Stewed pears, baked bananas, poached peaches, and homemade applesauce are all gentler than their raw versions. This is especially relevant for people with inflammatory bowel conditions, where raw fiber can aggravate symptoms. If you’re in the acute phase of stomach trouble, think soft, warm, and peeled. You can reintroduce raw fruit with the skin on once you’re feeling more like yourself.
