When your stomach is upset, the best foods are bland, low-fiber, and easy to digest: think white rice, plain toast, bananas, broth-based soups, scrambled eggs, and boiled potatoes. The goal is to give your digestive system something simple to process while keeping your energy and hydration up. What you eat matters, but so does the order you reintroduce foods and how quickly you move beyond the basics.
Start With Liquids, Then Add Bland Solids
If you’ve been vomiting, don’t jump straight to food. Wait at least 30 to 60 minutes after your last episode of vomiting before sipping clear liquids: water, diluted juice, broth, or an oral rehydration solution. Small, frequent sips work better than drinking a full glass at once, which can trigger another round of nausea.
After about six to eight hours of tolerating clear liquids without vomiting, you can start introducing solid food. Begin with small portions. Your stomach has been through a lot, and flooding it with a full meal will likely backfire. A few bites of toast or a quarter cup of rice is a reasonable first attempt.
The Best Foods for an Upset Stomach
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. Those four foods are still fine starting points, but doctors no longer recommend sticking to them exclusively. The American Academy of Pediatrics considers a strict BRAT diet too restrictive because it lacks protein, calcium, vitamin B12, and fiber. For children, following it for more than 24 hours can actually slow recovery.
Instead, use BRAT as a launching pad and add other gentle foods as soon as you can tolerate them:
- White rice and plain toast are easy to digest because they’re low in fiber. Fiber slows stomach emptying, which is normally a good thing but works against you when your stomach is irritated.
- Bananas replace potassium lost through vomiting and diarrhea. They’re also soft and naturally low in acid.
- Brothy soups deliver fluids and a small amount of salt, both of which help with rehydration.
- Boiled or baked potatoes (without butter or sour cream) provide starch and potassium without much flavor complexity to trigger nausea.
- Saltine crackers and dry cereal are mild enough to nibble on when even the thought of a full meal feels overwhelming.
- Oatmeal made with water is soothing and sits well for most people, though it has more fiber than white rice, so save it for when you’re past the worst of it.
- Scrambled eggs add protein, which your body needs to recover. Cook them plain, without cheese or butter.
- Skinless chicken or turkey is lean, bland, and protein-rich. Boiled or baked is gentler than fried.
- Cooked vegetables like carrots or zucchini are easier on the stomach than raw ones. Cooking breaks down the fiber that would otherwise slow digestion.
Why Low-Fiber, Refined Foods Help
It might feel counterintuitive to choose white rice over brown or white bread over whole wheat. Normally, whole grains are the healthier pick. But when your stomach is upset, fiber becomes a liability. It slows how quickly food moves out of your stomach, and in extreme cases, a large mass of undigested fiber can form a blockage. Refined starches break down quickly, move through your system faster, and demand less work from a digestive tract that’s already struggling. Once you’re feeling better (typically after two to three days), gradually reintroduce whole grains and raw vegetables.
Drinks That Help Beyond Water
Plain water is the foundation, but it doesn’t replace the sodium and potassium you lose through vomiting and diarrhea. Oral rehydration solutions are the most efficient option. Clear broth is another good choice because it provides both fluid and electrolytes. Peppermint tea is worth trying if nausea is your main symptom. The menthol in peppermint relaxes the smooth muscle lining your digestive tract by reducing calcium flow into those muscle cells, which eases cramping and that tight, queasy sensation.
Avoid coffee, alcohol, carbonated drinks, and anything with a lot of sugar. Sugary drinks can pull water into the intestines and worsen diarrhea. Caffeine stimulates gut contractions, which is the last thing you need.
Foods to Avoid Until You Recover
Some foods are almost guaranteed to make things worse. Greasy, fried, or heavily spiced foods require more digestive effort and can increase nausea. Dairy products are a common trigger during stomach illness because temporary lactose intolerance often develops when the intestinal lining is inflamed. Raw vegetables, nuts, seeds, and high-fiber cereals all slow stomach emptying. Acidic foods like tomatoes, citrus, and vinegar-based dressings can irritate an already-sensitive stomach lining.
Probiotics Can Shorten Recovery
Probiotic-rich foods like plain yogurt (if you can tolerate dairy) or fermented foods may help you bounce back faster. The evidence is strongest in children with diarrhea. One strain of beneficial bacteria reduced the duration of diarrhea from nine days to just over two days in a study of hospitalized children. Another strain cut diarrhea duration by about 25 hours compared to a placebo. These studies used supplement capsules rather than food, but regularly eating probiotic-containing foods during recovery is a reasonable and low-risk strategy. If dairy bothers you, look for non-dairy fermented options or a probiotic supplement.
A Realistic Recovery Timeline
Most stomach bugs and bouts of food-related nausea follow a predictable arc. The first six to twelve hours are usually the worst. During this window, focus entirely on hydration and rest. Once you can keep liquids down consistently, try a few bites of something bland.
Over the next 24 to 48 hours, gradually increase portion sizes and variety. Move from plain starches to adding protein (eggs, chicken) and then soft cooked vegetables. By day three or four, most people can return to a normal diet, though you may want to ease back into dairy, raw produce, and fatty foods rather than diving in all at once.
If diarrhea lasts more than 24 hours, you can’t keep any fluids down, you notice blood in your stool, or you develop a fever above 102°F, those are signs that something more serious is going on and warrants medical attention. Persistent inability to hydrate is the biggest risk, especially for young children and older adults.
