When your stomach is upset, the best foods are bland, low-fat, and easy to digest: think plain rice, bananas, broth, toast, and applesauce. But what you eat depends on where you are in your symptoms, and the old advice to stick strictly to those foods for days is outdated. Here’s how to manage your diet from the worst of it through recovery.
Start With Fluids, Not Food
If you’re actively vomiting or dealing with intense nausea, food isn’t the priority. Hydration is. In the first several hours of a stomach bug or food poisoning, stick to ice chips and small sips of water. Your gut needs time to settle before you ask it to process anything solid.
After about six hours without vomiting, you can move to clear liquids: water, broth, diluted juice, or an oral rehydration drink. The key to effective rehydration is getting both sodium and a small amount of sugar into the fluid, because your gut absorbs water fastest when sodium and glucose are present in roughly equal amounts. This is why plain water alone isn’t ideal if you’ve lost a lot of fluid through vomiting or diarrhea. Electrolyte drinks designed for illness work better than sports drinks, which tend to have too much sugar and not enough sodium.
Flat ginger ale is a classic home remedy, but most commercial ginger ale contains very little actual ginger. If you want the benefits of ginger (more on that below), ginger tea or a small piece of fresh ginger is a better bet.
What to Eat Once You Can Keep Fluids Down
Once you’ve tolerated clear liquids for several hours, typically after the first 24 hours, you can start introducing bland solid foods. The classic BRAT foods (bananas, rice, applesauce, toast) are still a reasonable starting point. They’re low in fiber, low in fat, and unlikely to irritate your stomach. Bananas also replace potassium lost through vomiting and diarrhea.
But here’s the update: a strict BRAT-only diet is no longer recommended by pediatric or gastroenterology guidelines. It lacks protein, calcium, vitamin B12, and fiber. Following it for more than a day or two can actually slow recovery, especially in children, because your gut needs adequate nutrition to repair itself. The American Academy of Pediatrics considers the BRAT diet too restrictive for kids with diarrhea and advises against using it beyond 24 hours.
Instead of limiting yourself to just those four foods, use them as a foundation and expand from there. Good options include:
- Plain crackers or pretzels for salt and easy carbohydrates
- Boiled or baked potatoes without butter or cream
- Plain chicken or turkey for protein, baked or steamed
- Oatmeal made with water
- Steamed vegetables like carrots or zucchini
- Eggs scrambled or boiled without added fat
The goal is gentle, low-fat foods that provide actual nutrition. Eat small amounts frequently rather than full meals, giving your digestive system manageable portions to work with.
Why Ginger Actually Works
Ginger is one of the few natural remedies for nausea with solid science behind it. The active compounds in ginger block serotonin receptors in the gut that trigger the vomiting reflex. They also help your stomach empty faster when motility has slowed, which is often part of what makes you feel nauseated in the first place.
You don’t need much. Research suggests that around 1 gram per day (roughly a half-inch piece of fresh ginger) taken for several days can meaningfully reduce nausea and vomiting. You can grate fresh ginger into hot water for tea, chew on crystallized ginger, or use ginger supplements. Just avoid ginger candy or ginger ale that lists “natural flavors” instead of real ginger as an ingredient.
Peppermint: Helpful but With a Catch
Peppermint tea can soothe nausea and reduce cramping because menthol relaxes the smooth muscle in your digestive tract by blocking calcium channels that trigger spasms. If your upset stomach involves cramping or bloating, peppermint tea is worth trying.
The catch: that same muscle-relaxing effect can loosen the valve between your esophagus and stomach. If your stomach upset involves acid reflux or heartburn, peppermint can make it worse. Stick to ginger instead if you’re dealing with burning or acid symptoms.
Foods and Drinks That Make Things Worse
Fat is the biggest culprit. It naturally slows stomach emptying, which means greasy or fried foods sit in your stomach longer and intensify nausea. Avoid fried foods, cheese, cream sauces, fatty meats, and butter until you’re fully recovered.
Other foods to skip while your stomach is recovering:
- Dairy products (temporarily harder to digest during gut inflammation)
- Spicy foods that irritate an already-inflamed stomach lining
- Raw vegetables and high-fiber foods that require more digestive effort
- Caffeine and alcohol, both of which can increase stomach acid and worsen dehydration
- Sugary drinks and full-sugar sodas, which can pull water into the gut and worsen diarrhea through osmotic effects
Carbonated beverages in small amounts (under about 300 ml) are generally fine and can even help settle mild nausea. But drinking more than that can cause gastric distension and bloating, making discomfort worse rather than better.
How Probiotics Can Speed Recovery
If your upset stomach involves diarrhea, probiotics can help. When used alongside proper hydration, probiotics have been shown to shorten the duration of diarrhea by about 25 hours and reduce the chance of it lasting beyond four days by nearly 60%.
The good news is that the specific strain doesn’t seem to matter much. Research hasn’t found important differences based on which probiotic you choose, what dose you take, or whether you use a single strain or a combination. Yogurt with live cultures (once you can tolerate dairy), kefir, or a basic probiotic supplement from the pharmacy are all reasonable options. Some of the most-studied strains for acute diarrhea include Lactobacillus rhamnosus GG and Saccharomyces boulardii, both widely available.
A Realistic Recovery Timeline
Everyone recovers differently, but a general progression looks like this. During the first six hours of active symptoms, stick to ice chips only. After six hours without vomiting, move to clear liquids: broth, water, diluted juice, electrolyte drinks. Sip slowly and see how your body responds.
After about 24 hours, try bland solids like toast, rice, or bananas. If those stay down, gradually expand to include lean protein and cooked vegetables over the next day or two. Most stomach bugs and mild food poisoning resolve within 24 to 72 hours. If you’re still unable to keep fluids down after 24 hours, or if symptoms worsen after the first day, that warrants medical attention.
The transition back to your normal diet should happen over three to five days. Reintroduce dairy, higher-fiber foods, and moderate fat one at a time. If something triggers a return of symptoms, back off and try again the next day. Your gut lining needs time to fully heal even after the worst symptoms pass.
