Bananas are the single most recommended fruit for diarrhea, and for good reason: they’re easy to digest, rich in potassium (which you lose rapidly during loose stools), and contain a type of starch that helps firm things up. But bananas aren’t the only fruit that can help. Several others play useful roles depending on how you prepare them and when you eat them during recovery.
Why Bananas Top the List
Bananas have been a go-to diarrhea remedy for decades, originally as part of the well-known BRAT diet (bananas, rice, applesauce, toast). While Harvard Health notes that restricting yourself to only those four foods isn’t necessary, bananas remain a smart first choice for a few specific reasons.
First, they’re high in potassium, an electrolyte your body loses in large quantities during diarrhea. Running low on potassium leaves you feeling weak and fatigued, so replenishing it matters. Second, less-ripe bananas contain resistant starch, a carbohydrate that doesn’t break down in the small intestine. Instead, it ferments in the large intestine, acting as a prebiotic that feeds beneficial gut bacteria. As a banana ripens and turns yellow, that resistant starch converts to regular starch, so greener bananas offer more of this gut-supporting benefit. Third, bananas are naturally low in fiber and gentle on an irritated digestive tract, making them easy to tolerate even when your stomach is unsettled.
Applesauce and Cooked Fruits
Raw fruit can be hard on your gut during a bout of diarrhea because of its insoluble fiber content, the type that adds bulk and speeds things along. Cooking fruit changes the equation. Heat breaks down insoluble fiber, softens the texture, and makes the fruit significantly easier to digest. This is why applesauce works well but a raw apple with the skin on could make things worse.
Applesauce is particularly helpful because apples are rich in pectin, a soluble fiber. Soluble fiber absorbs water in the intestines and forms a gel-like consistency, which helps slow down digestion and firm up loose stools. Peeling and cooking apples concentrates this benefit while removing the tough, insoluble skin fiber. The same logic applies to other cooked or stewed fruits like peaches and pears: once peeled and softened by heat, they become much gentler on your system.
Blueberries for Gut Repair
Blueberries contain high concentrations of anthocyanins, the pigments responsible for their deep color. These compounds do more than act as antioxidants. Research shows they strengthen the intestinal barrier by boosting the proteins that hold gut lining cells tightly together, reducing the inflammation that diarrhea causes in your intestinal walls. They also promote the growth of beneficial bacteria like Bifidobacterium and Lactobacillus in the gut, helping restore the microbial balance that diarrhea disrupts.
Dried blueberries are a traditional folk remedy for diarrhea in parts of Europe, and the concentrated anthocyanin content may explain why. Fresh blueberries are a reasonable option too, though you may want to start with small amounts and see how your stomach responds before eating a full serving.
Fruits That Replace Lost Electrolytes
Diarrhea doesn’t just cause discomfort. It drains your body of water and essential minerals, especially potassium and sodium. Replacing these electrolytes is a key part of recovery. Beyond bananas, UCSF Health recommends apricot and peach nectars as potassium-rich options. Cantaloupe and honeydew melon are also high in potassium and have the added benefit of being water-rich, which supports rehydration.
Fruit juice might seem like an easy way to get these nutrients, but proceed carefully. Juices can contain concentrated fructose, which pulls water into the intestines and can actually worsen diarrhea. If you drink fruit nectar or juice, dilute it with water and sip small amounts rather than drinking a full glass at once.
Fruits That Can Make Diarrhea Worse
Not all fruit is helpful when your gut is already struggling. The body can only absorb a limited amount of fructose at one time, and consuming more than that threshold draws excess water into the intestines, triggering or worsening loose stools. Apples (raw, with skin), grapes, and cherries are common culprits because of their high fructose content.
Some fruits also contain sugar alcohols like sorbitol, which the body absorbs poorly. Prunes are the classic example: their well-known laxative effect comes largely from their sorbitol content. Pears, peaches (raw), and sweet cherries also contain meaningful amounts of sorbitol. These are all fine fruits when your digestion is normal, but during a diarrhea episode, they’re likely to extend your misery.
Citrus fruits like oranges and grapefruit are another category to be cautious with. Their acidity can irritate an already inflamed gut lining, and their fiber content is mostly insoluble when eaten whole.
How to Eat Fruit During Recovery
Timing and preparation matter as much as which fruit you choose. In the first 24 hours of diarrhea, stick with the gentlest options: ripe bananas, plain applesauce, or small sips of diluted fruit nectar. These provide calories, potassium, and soluble fiber without taxing your digestive system.
As your symptoms start to settle, you can gradually add other soft, peeled, or cooked fruits. Stewed peaches, baked pears (without skin), and small portions of blueberries are reasonable next steps. The key is peeling when possible and cooking when practical, since both steps reduce the insoluble fiber load that can re-trigger loose stools.
Hold off on raw, high-fiber fruits with skins (apples, plums, berries in large quantities) until your bowel movements have been normal for at least a day or two. Everyone recovers at a different pace, so reintroduce foods based on how your body responds rather than following a rigid schedule. If a particular fruit seems to set you back, give it another few days before trying again.
