When your stomach is upset, the best foods are soft, bland, and low in fiber. Think plain rice, bananas, toast, and applesauce. These won’t cure your nausea or cramping, but they’re gentle enough to get some nutrients into your system without making things worse. What you avoid matters just as much as what you eat, and staying hydrated is the single most important thing you can do while your gut recovers.
The BRAT Diet: A Starting Point, Not a Meal Plan
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. These four foods are gentle on the digestive tract because they’re soft, mild in flavor, and low in fiber. They won’t actively reduce your nausea, but they’re a practical way to keep eating when most food sounds unbearable.
That said, the BRAT diet was never meant to be followed strictly for more than a day or two. It’s nutritionally limited, and sticking with it too long can leave you short on protein, fat, and calories your body needs to recover. The better approach is to use BRAT foods as your baseline and gradually add other tolerable foods as your symptoms improve. Once you can handle plain rice and toast without your symptoms getting worse, try adding boiled potatoes, plain crackers, steamed chicken, or clear broth.
Some treatment centers use a phased approach, starting with the most basic bland foods and then expanding the list as your gut settles. The key signal to move forward is simple: if what you’re eating isn’t making your symptoms worse, you’re ready to add more variety.
Why Bananas Deserve Special Mention
Bananas are one of the most useful foods during a stomach illness because they do double duty. They’re easy to digest, and they’re rich in potassium, an electrolyte you lose in significant amounts during diarrhea and vomiting. Potassium is essential for muscle function and fluid balance, so replacing it matters. A banana or two a day during recovery helps fill that gap in a way your stomach can actually tolerate.
Ginger for Nausea
Ginger is one of the few foods with solid evidence behind it for reducing nausea. Studies on pregnant women experiencing morning sickness found that roughly 1,000 to 1,500 milligrams of ginger per day provided meaningful relief. You don’t need to measure that precisely. A cup or two of strong ginger tea, a few pieces of crystallized ginger, or ginger chews throughout the day will get you in the right range.
Fresh ginger steeped in hot water is the simplest option. Slice a thumb-sized piece, pour boiling water over it, and let it steep for 10 minutes. Ginger ale is less reliable because many commercial brands use artificial ginger flavoring and contain a lot of sugar, which can actually worsen diarrhea.
Peppermint Tea for Cramping
If your upset stomach comes with cramping or spasms, peppermint tea can help. Peppermint relaxes the smooth muscles in your digestive tract, which reduces that tight, squeezing sensation in your gut.
There’s one important exception: if your stomach issues involve acid reflux or heartburn, skip the peppermint. It relaxes the same muscles at the top of your esophagus that normally keep stomach acid from rising, which can make reflux noticeably worse. For cramps without reflux, though, it’s one of the most effective home remedies available.
Hydration Matters More Than Food
When you’re vomiting or dealing with diarrhea, dehydration is the real danger, not missing a few meals. You lose water and electrolytes like sodium with every episode, and replacing both is critical. Plain water alone isn’t ideal because it doesn’t contain the electrolytes your body is losing.
Oral rehydration solutions (available at any pharmacy) are the gold standard. They contain a precise balance of salt, sugar, and water designed to maximize absorption. If you don’t have one on hand, clear broths work well because they naturally contain sodium. Coconut water is another reasonable option since it’s high in potassium and easier on the stomach than juice. Sip slowly rather than gulping. Small, frequent sips are far less likely to trigger vomiting than drinking a full glass at once.
Probiotics Can Shorten Recovery
If your upset stomach is caused by an infection (the classic “stomach bug”), probiotics can cut your recovery time. A large review of clinical trials found that probiotics reduced the average duration of diarrhea by about 30 hours. That’s more than a full day shaved off your misery.
Not all probiotics are equally useful here. The strain with the strongest evidence for infectious diarrhea is Lactobacillus GG (often sold as LGG). In children with rotavirus, this strain reduced diarrhea duration by about 38 hours compared to no treatment. The yeast strain Saccharomyces boulardii also showed benefit. Look for these specific strains on the label rather than grabbing a generic probiotic blend. Yogurt with live active cultures can provide some benefit too, as long as dairy doesn’t make your symptoms worse.
Foods That Will Make It Worse
Knowing what to avoid is half the battle. These categories consistently irritate an already-upset stomach:
- Spicy foods: Chili peppers, hot sauces, and heavy black pepper directly irritate the stomach lining and can increase cramping.
- Acidic foods: Citrus fruits, tomatoes, coffee, and citrus juices raise stomach acidity, which worsens nausea and can trigger reflux.
- Fatty and fried foods: These slow digestion significantly, keeping food sitting in your stomach longer and increasing the feeling of fullness and nausea. Skip fried foods, fatty meats, and rich desserts.
- Dairy (for most people): Milk, cheese, and ice cream can be hard to digest during a stomach illness, even if you normally tolerate them fine. Yogurt with live cultures is the one exception worth trying.
- Chocolate: It contains both caffeine and fat, making it a double trigger.
- Alcohol and carbonated drinks: Alcohol irritates the stomach lining directly. Carbonation can increase bloating and gas when your gut is already struggling.
A Practical Eating Plan for Recovery
For the first 12 to 24 hours when symptoms are at their worst, focus entirely on hydration. Sip broth, oral rehydration solution, or diluted ginger tea. Don’t force yourself to eat solid food if everything is coming back up.
Once you can keep liquids down, start with the blandest options: plain white rice, a banana, dry toast, or a few plain crackers. Eat small amounts every two to three hours rather than full meals. Your stomach handles small volumes much better when it’s inflamed.
Over the next day or two, expand to boiled or steamed potatoes, plain cooked chicken or turkey, oatmeal, and applesauce. Keep portions small and meals frequent. Most stomach bugs resolve within 48 to 72 hours, and you can typically return to your normal diet within a day or two after symptoms stop. If you’re still unable to keep food or liquids down after 24 hours, or if you notice signs of dehydration like dark urine, dizziness, or a dry mouth, that’s worth a call to your doctor.
