When your stomach is churning, the right foods can calm things down while the wrong ones make everything worse. The goal is simple: eat things that are easy to digest, keep you hydrated, and give your body enough nutrition to recover. Here’s what actually helps.
Start With Fluids, Not Food
Before you worry about solid food, focus on replacing the water and minerals your body is losing, especially if you’re dealing with vomiting or diarrhea. Plain water works, but your small intestine absorbs fluid faster when it contains a small amount of sugar and salt together. That’s the science behind oral rehydration solutions like Pedialyte: sodium helps your gut absorb glucose, and glucose helps your gut absorb sodium, pulling water along with both.
If you don’t have a rehydration drink on hand, you can sip diluted broth, coconut water, or a homemade mix of water with a pinch of salt and a small spoonful of sugar. Avoid gulping large amounts at once. Small, frequent sips are far less likely to trigger another round of nausea. Sports drinks are an option, though many contain more sugar than your stomach needs right now.
The Best Foods for a Sensitive Stomach
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. These foods are bland, low in fiber, and easy on your digestive system. They’re a fine starting point for the first day or two. But as Harvard Health points out, there’s no need to restrict yourself to just those four items, and doing so for more than a couple of days can leave you short on protein and other nutrients you need to recover.
Once you can keep bland food down, broaden your choices to include other gentle options:
- Plain crackers or pretzels provide simple carbohydrates and a bit of salt.
- Boiled or baked potatoes (without butter or heavy toppings) are starchy and easy to digest.
- Plain chicken or turkey breast adds lean protein without much fat.
- Oatmeal contains soluble fiber, which dissolves in water and forms a gel that slows digestion and can help firm up loose stools.
- Eggs (scrambled or boiled) are mild and nutrient-dense.
- Bone broth or clear soup delivers fluids, electrolytes, and a little protein in one package.
The common thread is bland, low-fat, and lightly seasoned. You’re not trying to eat a full meal. Small portions every few hours put less strain on your stomach than three large ones.
Why Bananas and Oats Stand Out
Bananas deserve special mention because they’re rich in potassium, a mineral you lose quickly through vomiting and diarrhea. They’re also a source of soluble fiber, which absorbs water in the gut and adds bulk to watery stool. Oats work similarly. Soluble fiber, found in oats, apples, carrots, and barley, forms a gel-like material in the stomach that slows everything down, giving your digestive system time to recover.
Insoluble fiber does the opposite. It speeds material through your system, which is normally a good thing but not when your gut is already in overdrive. Whole-wheat bread, wheat bran, raw vegetables, and nuts are all high in insoluble fiber and better saved for when you’re feeling normal again.
Ginger and Peppermint Actually Work
Ginger is one of the few natural remedies with real evidence behind it. In a study of patients with functional digestive problems, ginger sped up gastric emptying, cutting the time it took the stomach to move food along from about 16 minutes to 12 minutes. Ginger appears to work by interacting with serotonin receptors in the gut, the same pathway targeted by prescription anti-nausea medications. Fresh ginger tea, ginger chews, or even flat ginger ale (with real ginger listed in the ingredients) can all help settle nausea.
Peppermint relaxes the smooth muscle throughout the digestive tract, which can ease cramping and bloating. A cup of peppermint tea is a simple option. One caveat: because peppermint relaxes the valve between your esophagus and stomach, it can make acid reflux worse. If heartburn is part of your problem, skip the peppermint and stick with ginger.
Foods and Drinks to Avoid
Some foods are obvious offenders, but a few might surprise you.
- Fatty or fried foods take longer to digest and can increase nausea and cramping.
- Dairy products are harder to break down when your gut is inflamed. Even people who normally tolerate lactose well can struggle with milk or cheese during a stomach illness.
- Spicy foods can slow gastric emptying. Red pepper sauce, in particular, has been shown to delay the stomach’s ability to move food through. While capsaicin in small amounts can actually protect the stomach lining under normal conditions, it’s not worth the gamble when you’re already nauseous.
- Coffee and alcohol both irritate the stomach lining and act as diuretics, pulling water out of your body when you need to be holding onto it.
- Sugary drinks and fruit juice can draw water into the intestines and worsen diarrhea. This is especially true of apple juice, which is high in a sugar (sorbitol) that many people absorb poorly.
- Raw vegetables and high-fiber cereals are tough to break down and can increase gas and bloating.
Probiotics Can Shorten Recovery
If your upset stomach involves diarrhea, certain probiotics can help. The most studied strain, Lactobacillus rhamnosus GG, shortened the duration of diarrhea by nearly a full day in a large meta-analysis covering over 3,800 patients. Look for it in supplement form or in specific yogurt brands that list it on the label. Not all probiotics are the same, so the strain matters. Plain yogurt with live cultures is a reasonable option once you can tolerate dairy again, but during the worst of your symptoms, a supplement may be easier on your stomach.
A Practical Timeline
For the first few hours, especially if you’re vomiting, stick to clear fluids only. Sip water, broth, or an electrolyte drink. Don’t force food.
Once nausea starts to ease (usually after 6 to 12 hours), try a few bites of something bland: a few crackers, a small bowl of plain rice, or half a banana. If that stays down, eat small amounts every two to three hours.
By day two or three, you can start adding lean protein and cooked vegetables back in. Most stomach bugs resolve within 24 to 72 hours. If you’re still unable to keep fluids down after 24 hours, notice dark-colored urine, a rapid heart rate, or a fever above 102°F, those are signs of dehydration or an infection that needs medical attention.
