Several everyday foods can help firm up your stool and speed recovery from diarrhea. The key is choosing options that are low in fiber, easy to digest, and capable of absorbing excess water in your intestines. Here are 12 foods that work, along with why they help and how to use them.
Bananas
Bananas are one of the most reliable foods for slowing diarrhea. The starch in bananas absorbs water in your colon, which firms up loose stool. They’re also rich in potassium, an electrolyte your body loses rapidly during bouts of diarrhea. Slightly underripe bananas contain more resistant starch than fully ripe ones, making them even more effective as a binding food. They’re gentle on the stomach and unlikely to trigger nausea.
White Rice
Plain white rice is rich in starch that gets converted into soluble fiber in your gut. That soluble fiber absorbs water and slows digestion, giving your intestines time to pull more fluid back into your body instead of sending it out as watery stool. Stick with plain white rice, not brown rice. Brown rice has significantly more insoluble fiber, which can actually speed things through your digestive tract and make diarrhea worse.
Plain White Toast
Toast made from white or gluten-free bread is bland, low in fiber, and easy to digest. It provides simple carbohydrates for energy without irritating your gut. Skip whole-grain or seeded breads during a flare-up since the extra fiber and roughage work against you. Dry toast or lightly topped with a thin layer of smooth peanut butter is a safe bet.
Applesauce
Applesauce contains pectin, a type of soluble fiber that binds excess water in your intestines. Raw apples have pectin too, but their skin contains insoluble fiber that can irritate a sensitive gut. Cooking apples down into applesauce breaks down that roughage while preserving the pectin. Choose unsweetened versions, since added sugars can pull more water into the intestines and worsen loose stools.
Boiled or Mashed Potatoes
Peeled, boiled, or mashed potatoes are starchy, bland, and a good source of potassium. UW Health includes them on their short list of foods to eat when diarrhea is at its worst. The important detail: peel them first. Potato skin adds fiber you don’t need right now. Skip butter, cream, or gravy, all of which contain fat that can trigger your colon to secrete more fluid.
Oatmeal
Oatmeal is loaded with soluble fiber, which retains water and turns into a gel during digestion. That gel slows everything down, giving your intestines more time to absorb nutrients and fluids. It also helps bulk up stool. Cook it with water rather than milk, since dairy contains lactose that many people struggle to digest even under normal circumstances. During diarrhea, when your gut lining is already irritated, lactose can be even harder to process.
Saltine Crackers
Saltine crackers serve a dual purpose. They’re made from refined white flour, making them easy to digest, and the salt provides a quick boost of sodium. Sodium slows fluid loss and helps your body retain the water you’re drinking. Pretzels work the same way. These are good options when you feel too nauseated to eat a full meal but need to get something in your system.
Chicken Noodle Soup
Chicken noodle soup combines several things your body needs during diarrhea: sodium from the broth, simple carbohydrates from the noodles, easily digestible protein from the chicken, and fluid to replace what you’re losing. The warm broth is also gentle on an irritated stomach. Brothy soups in general are a smart early food. Avoid cream-based soups, which contain fat and dairy that can worsen symptoms.
Plain Yogurt
While most dairy is worth avoiding during diarrhea, plain yogurt is an exception. The fermentation process breaks down much of the lactose, and yogurt contains beneficial bacteria from the Lactobacillus and Bifidobacterium families. These probiotics help restore the balance of your gut microbiome, which is especially useful if your diarrhea was triggered by antibiotics or a stomach bug. Over time, these bacteria help regulate bowel movements and reduce gut inflammation. Choose plain, unsweetened yogurt. Flavored varieties often contain added sugars that can draw more water into the intestines.
Skinless Chicken or Turkey
Lean, white-meat poultry with the skin removed provides protein your body needs to recover without adding fat that could aggravate your gut. Memorial Sloan Kettering recommends introducing it as you move past the initial acute phase, typically after one to two days of eating only the blandest foods. Bake or boil it rather than frying, and skip heavy sauces or seasonings.
Eggs
Scrambled or boiled eggs are one of the easiest proteins to digest. They provide essential amino acids and calories without the fat content of red meat. They’re often well tolerated even when your stomach is still sensitive, and they pair easily with other recovery foods like white toast or plain rice. Cook them simply: no butter, cheese, or cream.
Black Tea
Black tea contains tannins, plant compounds that act as natural astringents in your intestines. Tannins work by binding to proteins and forming a protective layer over the lining of your gut, reducing irritation and decreasing the amount of fluid your intestines secrete. This is the same mechanism used in some pharmaceutical anti-diarrheal preparations. Drink it plain and decaffeinated if possible, since caffeine can stimulate your bowels. The warm liquid also contributes to hydration.
How These Foods Work Together
These 12 foods address diarrhea through a few overlapping mechanisms. Starchy foods like white rice, potatoes, and bananas absorb excess water in the intestines and add bulk to stool. Soluble fiber in oatmeal and applesauce turns into a gel that slows digestion. Salty foods and broth replace sodium that’s being lost, which helps your body retain fluid. Lean proteins provide the building blocks for recovery without taxing your digestive system. And probiotic-rich yogurt helps restore the microbial balance in your gut.
No single food will stop diarrhea on its own. The combination matters, and so does what you avoid. Fried or fatty foods, dairy (other than yogurt), and sugar alcohols like sorbitol, mannitol, and xylitol, found in sugar-free gum and candy, can all make diarrhea significantly worse. Fatty foods that aren’t absorbed properly pass into the colon, where they’re broken down into fatty acids that trigger your colon to secrete even more fluid.
A Practical Recovery Timeline
For the first several hours, focus on clear liquids: water, clear broth, and plain tea. Aim to drink a cup of water after every loose bowel movement. Once you can tolerate liquids without worsening symptoms, introduce the blandest foods on this list: bananas, white rice, toast, applesauce, crackers, and oatmeal.
After 24 to 48 hours on these simple foods, you can start adding back lean proteins like chicken, eggs, and fish. From there, gradually reintroduce cooked vegetables (peeled and low-fiber options like carrots and squash first), then work your way back toward your normal diet. Most people can return to regular eating within a few days, though your gut may remain slightly sensitive for a week or so. If watery, frequent stools persist beyond two to three days despite dietary changes, that’s worth a call to your doctor.
