When you’re dealing with diarrhea and nausea at the same time, the best foods are bland, low in fat, and served at room temperature or cool. Think plain white rice, bananas, brothy soups, boiled potatoes, and dry toast. These foods are easy on your stomach, unlikely to trigger more nausea, and gentle enough to move through your digestive system without making diarrhea worse. The key is to eat small amounts frequently rather than sitting down to a full meal.
Best Foods for the First 24 Hours
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a reasonable starting point for the first day or two, but you don’t need to limit yourself to just those four foods. Other options that are equally easy to digest include brothy soups, oatmeal, plain crackers, boiled potatoes, and unsweetened dry cereal. All of these are low in fat, low in fiber that could irritate your gut, and unlikely to provoke more nausea.
Temperature matters more than you might expect. Hot food releases more aroma, and strong smells can intensify nausea. Eating food at room temperature or slightly cool cuts down on those odor triggers. If you’re having soup, let it cool until it’s warm rather than steaming.
How to Eat When You Feel Too Sick to Eat
Your stomach empties more predictably when it’s not overloaded. Eating five or six small portions spread throughout the day puts far less strain on your digestive system than two or three normal-sized meals. Even a few bites of plain rice or half a banana counts. The goal isn’t to hit your normal calorie intake. It’s to keep something moving through so your body has fuel to recover.
If nausea is the bigger problem, try nibbling on dry crackers or plain toast before attempting anything with moisture. Sipping a small amount of clear fluid between bites, rather than drinking a full glass with food, also helps keep your stomach from feeling overfull.
Adding Protein as You Improve
Once your stomach starts to settle, usually after 24 to 48 hours, you’ll want to bring in some protein. Sticking with only starches and fruit for too long leaves your body short on the nutrients it needs to heal. Good options include skinless chicken breast, white fish, eggs, soft tofu, cottage cheese, and smooth yogurt. The common thread is that these are all lean, tender, and cooked without added fat. Fried or greasy protein will likely send you right back to where you started.
Cooked carrots, butternut squash, pumpkin, sweet potatoes without skin, and avocado are also worth adding at this stage. They’re nutrient-dense but still gentle on your digestive tract.
Hydration Is More Important Than Food
Diarrhea pulls water and electrolytes out of your body fast. Replacing that fluid is actually more urgent than eating solid food. Water alone isn’t ideal because it doesn’t replace the sodium and potassium you’re losing. A simple oral rehydration drink you can make at home: mix 4 cups of water with half a teaspoon of table salt and 2 tablespoons of sugar. Sip it steadily throughout the day rather than gulping large amounts at once.
Signs that you’re getting dehydrated include dark-colored urine, urinating less often than usual, extreme thirst, dizziness, and skin that doesn’t flatten back right away after you pinch it. Confusion or feeling unusually tired are later warning signs that dehydration is becoming serious.
Foods and Drinks That Make Things Worse
Some foods actively pull water into your intestines, which worsens diarrhea through a process called osmotic load. Sugar alcohols are the biggest offenders. Sorbitol, found naturally in some fruits and added to sugar-free gum, sugar-free mints, and dietetic candies, is a well-documented diarrhea trigger. Even a vitamin C supplement sweetened with sorbitol has been shown to cause osmotic diarrhea. Check the labels on anything marked “sugar-free” while you’re recovering.
Other foods to skip until you’re feeling better:
- Dairy (except yogurt and cottage cheese) because lactose can be harder to digest when your gut lining is irritated
- Fatty or fried foods because fat slows stomach emptying and can worsen nausea
- Caffeine and alcohol because both increase fluid loss and stimulate the gut
- Raw vegetables and high-fiber foods because insoluble fiber speeds transit through the colon
- Spicy foods because capsaicin irritates an already inflamed digestive tract
- Fruit juice in large amounts because the fructose concentration can trigger more diarrhea
Ginger for Nausea Relief
Ginger is one of the few natural remedies with solid clinical backing for nausea. A large trial of 644 patients found that 0.5 to 1.0 grams of ginger per day significantly reduced nausea. That’s roughly a quarter-inch slice of fresh ginger steeped in hot water, or about two standard ginger capsules from a supplement aisle. Ginger tea, ginger chews, and even flat ginger ale (with real ginger, not just flavoring) can help take the edge off.
Higher doses, around 1.5 grams per day, didn’t show additional benefit in that trial. So more isn’t better here.
Soluble Fiber Helps Firm Things Up
Not all fiber is the same. Insoluble fiber, the kind in raw vegetables and whole wheat, speeds things through your gut and makes diarrhea worse. Soluble fiber does the opposite. It absorbs water and forms a gel-like consistency that helps bulk up loose stool. The best soluble fiber sources when you’re sick are foods you’re probably already eating on a bland diet: oatmeal, applesauce, bananas, and potatoes. These do double duty by being easy to digest and helping your stool return to a more normal consistency.
Probiotics Can Shorten Recovery
If your diarrhea is from an infection like stomach flu or food poisoning, certain probiotics can cut the duration by roughly a day. The two strains with the strongest evidence are Lactobacillus rhamnosus GG (often labeled LGG) and Saccharomyces boulardii, a beneficial yeast. Both have been studied in large trials and shown to reduce both the length of diarrhea and how frequently you need to go. Look for products that contain at least 10 billion colony-forming units (CFU), which is the dose range used in the clinical research. Taking them for 5 to 10 days covers most acute illness.
Yogurt with live active cultures provides some probiotic benefit too, though typically at lower concentrations than a dedicated supplement.
Signs You Need More Than Food Adjustments
Most bouts of diarrhea and nausea from stomach bugs or food poisoning resolve within a few days with rest, fluids, and bland eating. But diarrhea lasting more than 24 hours, especially combined with confusion, sunken eyes, or an inability to keep fluids down, warrants a call to your doctor. Bloody stool, a fever above 102°F, or severe abdominal pain are signals that something beyond a routine stomach bug may be going on.
