Certain bland, starchy, and soluble-fiber-rich foods can help firm up loose stools and speed your recovery from diarrhea. Bananas, white rice, applesauce, oatmeal, boiled potatoes, and lean proteins like chicken and eggs are among the most effective choices. But what you avoid eating matters just as much as what you eat, and staying hydrated is the single most important thing you can do while your gut heals.
Why Certain Foods Help
Diarrhea happens when food moves too quickly through your digestive tract for water and nutrients to be properly absorbed. The foods that help counteract this share a few key traits: they’re low in fiber that adds bulk without absorbing water, they’re easy to digest so your gut doesn’t have to work hard, and many contain soluble fiber that actually pulls excess water out of your stool.
Soluble fiber is the star player here. It absorbs water in your intestines, slows down how fast food passes through your gut, and gets fermented by bacteria in your colon to produce compounds that help your intestinal lining reabsorb water and electrolytes. Bananas and apples are particularly rich in a type of soluble fiber called pectin, which binds excess water and helps firm things up. Plain white rice works similarly: its starch gets converted into soluble fiber during digestion.
Best Foods to Eat During Diarrhea
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 there’s no clinical research proving it works better than other bland foods. You don’t need to limit yourself to just those four items. The goal is to eat foods that are low in insoluble fiber (under 2 grams per serving), gentle on your stomach, and nutritionally balanced enough to support recovery.
Starches and Grains
- White rice is one of the most effective options, rich in easily digestible starch
- Plain white bread and toast made with refined flour
- Oatmeal and other hot cereals like cream of wheat or cream of rice
- Plain pasta or noodles made with refined flour
- Crackers including saltines and graham crackers
- Boiled or mashed potatoes without skin
Fruits and Vegetables
- Bananas provide pectin to firm stools and potassium to replace what diarrhea depletes
- Applesauce (unsweetened) delivers pectin without the insoluble fiber of raw apple skin
- Cooked carrots, butternut squash, and sweet potatoes without skin
- Avocado, which is bland and nutrient-dense
Proteins
When diarrhea is severe, your body still needs protein to recover. Chicken, fish, and eggs are all well tolerated. Cottage cheese and yogurt (plain, without added sugar) are also good choices. Smooth peanut butter provides protein and calories in an easy-to-digest form. The key is to prepare these simply: baked, boiled, or steamed rather than fried.
Foods and Drinks That Make Diarrhea Worse
Some foods actively pull water into your intestines or speed up gut motility, which is the opposite of what you want. Avoiding these can be just as effective as eating the right things.
Greasy and fried foods are especially problematic. Fats that aren’t absorbed in your small intestine pass into your colon, and leftover bile acids from fat digestion trigger your colon to secrete water, worsening diarrhea.
Sugar-free gums and candies contain sugar alcohols like sorbitol, mannitol, and xylitol. These are poorly absorbed in your small intestine and accumulate in your colon, where they increase osmotic pressure and prevent water absorption. Even in healthy people, excessive sorbitol from chewing gum can cause diarrhea, bloating, and weight loss.
Fruit juice is a surprisingly common culprit, especially in children. Juice has a carbohydrate concentration of 11 to 16 percent, compared to about 2.5 to 3 percent in oral rehydration solutions. That sugar load can overwhelm your intestine’s ability to absorb carbohydrates, causing osmotic diarrhea on top of whatever’s already going on. The American Academy of Pediatrics specifically states that juice is not appropriate for treating dehydration or managing diarrhea.
Other foods and drinks to skip during recovery:
- Dairy products (except yogurt and cottage cheese, which are usually tolerated)
- Alcohol and caffeinated drinks, which stimulate your gut and promote fluid loss
- Raw vegetables, leafy greens, and salads high in insoluble fiber
- Nuts, seeds, popcorn, and beans
- Acidic foods like tomato sauce and citrus
- Highly sweetened foods including candy, pastries, and soda
Hydration Matters More Than Food
Diarrhea drains water and electrolytes from your body rapidly, and dehydration is the main danger, especially for young children and older adults. Drinking plain water helps, but it doesn’t replace the sodium and potassium you’re losing. Oral rehydration solutions like Pedialyte contain the right balance of sugar, sodium, and minerals to help your body actually absorb the fluid.
You can make a basic version at home: mix 4 cups of water with half a teaspoon of salt and 2 tablespoons of sugar. Brothy soups are another practical option, since they provide fluid, sodium, and some calories in one package. Sports drinks like Gatorade aren’t ideal because their sugar-to-electrolyte ratio isn’t well matched to what your body needs during diarrhea.
Probiotics Can Shorten Recovery
Certain probiotic strains have solid evidence behind them for reducing how long diarrhea lasts. The yeast Saccharomyces boulardii is one of the best studied. It’s naturally resistant to stomach acid and antibiotics, and a meta-analysis found it reduces the duration of acute diarrhea by roughly one day. In one clinical trial, nearly half of patients taking it had recovered by day three, compared to about a quarter in the control group.
Lactobacillus rhamnosus GG (often labeled as LGG) and Lactobacillus reuteri are the other well-researched strains. You can find these in supplement form at most pharmacies. Yogurt with live active cultures provides some probiotic benefit, though typically at lower concentrations than dedicated supplements.
How to Transition Back to Normal Eating
Once your stools start to firm up and you’re keeping food down comfortably, gradually reintroduce more nutritious foods. Skinless chicken or turkey, fish, cooked squash, sweet potatoes, and eggs are good next steps because they’re still easy to digest but provide the protein and micronutrients your body needs to fully recover. There’s no need to stay on a restrictive bland diet for more than a day or two.
Add foods back one at a time so you can identify anything that triggers a setback. High-fiber foods, dairy, fatty foods, and raw fruits and vegetables should be the last things you reintroduce. Most episodes of acute diarrhea from stomach bugs or food poisoning resolve within two to three days with proper hydration and gentle eating.
Signs That Need Medical Attention
For adults, diarrhea that lasts more than two days without improvement warrants a visit to your doctor. Other red flags include a fever above 102°F, bloody or black stools, severe abdominal pain, and signs of dehydration like excessive thirst, very dark urine, dizziness, or little to no urination.
Children need attention sooner. If a child’s diarrhea doesn’t improve within 24 hours, or if they develop a fever above 102°F, have no wet diaper for three or more hours, cry without tears, or seem unusually sleepy or irritable, seek medical care promptly. Skin that stays “tented” when you pinch and release it is a classic sign of significant dehydration in children.
