When you have diarrhea, the best foods are bland, low-fiber, and easy to digest: white rice, bananas, plain toast, brothy soups, boiled potatoes, and oatmeal. Equally important is replacing the fluid and salt you’re losing with every loose stool. Most bouts of diarrhea improve within a couple of days, and what you eat during that window can make a real difference in how quickly you recover.
Start With Bland, Easy-to-Digest Foods
You’ve probably heard of the BRAT diet (bananas, rice, applesauce, toast). It’s a fine starting point for the first day or two, but there’s no research showing it works better than other bland options, and sticking to only those four foods limits the protein and nutrients your body needs to bounce back. A broader list of gentle foods gives you more to work with:
- White rice and plain pasta
- Bananas
- Plain toast or crackers
- Oatmeal
- Boiled or baked potatoes (without skin)
- Brothy soups (chicken, vegetable, or bone broth)
- Unsweetened dry cereal
- Applesauce
These foods are low in fat, low in insoluble fiber, and unlikely to irritate your gut. They also provide some calories and carbohydrates so you’re not running on empty while your digestive system recovers.
Adding Nutrition as You Improve
Once you can tolerate those basic foods without your symptoms getting worse, start bringing in options with more protein and vitamins. Good next-step foods include skinless chicken or turkey, fish, eggs, avocado, cooked carrots, sweet potatoes without skin, and cooked squash like butternut or pumpkin. These are still bland and gentle but give your body the building blocks it needs to heal.
There’s no strict timeline for when to make this shift. It’s based on how you feel. If a day of plain rice and broth sits well, try adding some baked chicken at your next meal. If that goes fine, keep expanding. The goal is to get back to a normal, varied diet as soon as your gut can handle it.
Why Hydration Matters More Than Food
Diarrhea pulls water and electrolytes out of your body fast. Dehydration is the main danger, especially for young children and older adults. Aim to drink at least 1 cup (240 mL) of liquid every time you have a loose bowel movement, on top of your normal fluid intake.
Water alone isn’t ideal because it doesn’t replace the sodium and potassium you’re losing. An oral rehydration solution is more effective, and you can make one at home using the World Health Organization’s formula: about 4 cups of water, half a teaspoon of salt, and 2 tablespoons of sugar. Stir until dissolved and sip throughout the day. The sugar isn’t just for taste; it helps your intestines absorb the sodium and water more efficiently.
Other good fluid options include diluted juice, clear broth, coconut water, or a sports drink diluted with equal parts water and a pinch of added salt. Avoid full-strength fruit juice, which can actually pull more water into your intestines and make things worse.
Foods and Drinks That Make Diarrhea Worse
Some foods actively work against you during a bout of diarrhea. Knowing what to skip is just as useful as knowing what to eat.
Sugar alcohols are a common and often overlooked trigger. Sorbitol, mannitol, xylitol, and maltitol are found in sugar-free gum, sugar-free candy, diet drinks, and some liquid medications. They all have laxative properties. As little as 5 to 20 grams of sorbitol per day can cause gas, cramping, and urgency, and doses above 20 grams reliably cause diarrhea. Sorbitol also occurs naturally in certain fruits: apples, pears, peaches, plums, prunes, apricots, and dried fruits like dates, figs, and raisins. These are normally healthy foods, but during active diarrhea they can make symptoms linger.
Dairy products are worth avoiding temporarily. Diarrhea can temporarily reduce the enzyme that breaks down lactose, the sugar in milk. Even if you’re not normally lactose intolerant, milk, ice cream, and soft cheeses may cause bloating and more loose stools until your gut lining recovers.
Fatty and fried foods speed up intestinal contractions, which is the opposite of what you want. Greasy meals, fast food, and rich sauces are hard to digest under normal conditions and much harder when your gut is already irritated.
Caffeine and alcohol both stimulate the gut and increase fluid loss. Coffee, energy drinks, and alcoholic beverages should wait until you’ve fully recovered.
Raw vegetables and high-fiber foods like whole grains, beans, broccoli, and cabbage add bulk and gas. Insoluble fiber (the kind in wheat bran, raw veggies, and fruit skins) speeds things through the digestive tract. Soluble fiber, found in oats and peeled cooked potatoes, is gentler because it forms a gel that actually absorbs excess water in the gut. That’s why oatmeal and peeled potatoes are on the “safe” list while a raw salad is not.
Probiotics Can Shorten Recovery
Certain probiotic strains can help your gut recover faster. The most studied one for acute diarrhea is Saccharomyces boulardii, a beneficial yeast available over the counter in most pharmacies. Pooled data from clinical trials shows it reduces the duration of diarrhea by roughly 20 hours compared to no treatment and significantly lowers the chance of still having diarrhea on days 3 and 4. It’s generally well tolerated and can be taken alongside oral rehydration.
Yogurt with live active cultures is another option, though if you’re avoiding dairy, a capsule-based probiotic may be easier on your stomach. Look for products that list specific strains on the label rather than just “probiotic blend.”
What to Watch For
Most diarrhea clears up on its own within two to three days. Certain signs mean it’s time to get medical attention. In adults, those include diarrhea lasting more than two days without any improvement, a fever above 102°F (39°C), blood or black color in your stool, severe abdominal or rectal pain, and signs of dehydration like excessive thirst, very dark urine, dizziness, or skin that stays “tented” when you pinch it.
Children need faster attention. If a child’s diarrhea hasn’t improved in 24 hours, or if there are no wet diapers for three or more hours, a dry mouth, no tears when crying, or unusual sleepiness, those are signs of dehydration that require prompt care.
