What Foods Help With Diarrhea and What to Avoid

Bland, low-fiber foods like white rice, bananas, plain toast, and boiled chicken are the most reliable choices for calming diarrhea and firming up your stool. These foods are easy to digest, unlikely to irritate your gut, and give your body basic fuel while it recovers. But what you eat matters less than how quickly you return to a full diet once you’re able, since staying on restricted foods too long can actually slow recovery.

The Best Foods to Eat Right Now

If you’re in the thick of it, focus on what dietitians call a “white diet”: bananas, white rice, applesauce, white toast, plain noodles, chicken breast, white fish, eggs, soft tofu, cottage cheese, and smooth yogurt. These foods share a few key traits. They’re low in fat, low in insoluble fiber, and gentle on an inflamed digestive tract. They won’t stimulate your gut to push things through faster.

Bananas deserve special mention. They’re rich in potassium, one of the electrolytes you lose fastest during diarrhea, and their natural pectin helps absorb excess water in your intestines. Ripe bananas are easier to digest than green ones.

White rice and plain toast work because they’ve had most of their fiber stripped away during processing. That’s normally a nutritional downside, but during diarrhea it’s an advantage. Less fiber means less bulk moving through your gut, giving your intestines time to recover.

Protein Sources That Won’t Make Things Worse

Your body needs protein to heal, but fatty or heavily seasoned meats can trigger more cramping. Stick to tender, well-cooked lean options: skinless chicken breast, mild white fish like cod or tilapia, scrambled or boiled eggs, and soft tofu. Cook them without added fat when possible. Baking, boiling, or steaming are better than frying.

Eggs are particularly useful because they’re calorie-dense in a small package. When you can barely eat, getting meaningful nutrition from a few bites matters.

Why the BRAT Diet Has Limits

You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a fine starting point for the first day or two when you’re at your sickest, but it’s not a recovery plan. Those four foods lack calcium, vitamin B12, protein, and adequate fiber. The American Academy of Pediatrics no longer recommends a strict BRAT diet for children with diarrhea because it’s too restrictive and may actually slow gut recovery if followed for more than 24 hours.

For adults, think of BRAT foods as a floor, not a ceiling. If you can tolerate chicken, eggs, yogurt, or noodles alongside those basics, eat them. The goal is to get nutrients in, not to limit yourself unnecessarily.

Foods and Drinks That Make Diarrhea Worse

Some foods actively pull water into your intestines, loosening your stool further. Sugars are the main culprit. Fructose, found naturally in fruits like peaches, pears, cherries, and apples, triggers your gut to release water and electrolytes. People who consume more than 40 to 80 grams of fructose per day often develop diarrhea even when they’re healthy. Fruit juices, sodas, and sweetened applesauce concentrate fructose in ways whole fruit doesn’t.

Artificial sweeteners like sorbitol, mannitol, and xylitol are even worse. They’re common in sugar-free gum, candy, and some medications. Your body can’t fully absorb them, so they sit in your gut drawing in water.

Caffeine speeds up your entire digestive system. Coffee, tea, chocolate, and many sodas all contain it. Even decaf coffee has some gut-stimulating compounds, so it’s worth avoiding during active symptoms.

Dairy is tricky. Lactose, the sugar in milk, requires a specific enzyme to digest. During and after a bout of diarrhea, your gut’s ability to produce that enzyme drops temporarily. This means even people who normally handle dairy fine may get worse symptoms from milk, ice cream, or soft cheese while they’re sick. Yogurt is generally better tolerated because the fermentation process breaks down much of the lactose.

Other common triggers to avoid until you’re feeling better:

  • Greasy or fried foods, which stimulate contractions in your colon
  • Raw vegetables and salads, which contain tough insoluble fiber
  • Spicy foods, which can irritate an already inflamed gut lining
  • Alcohol, which is both a gut irritant and a dehydrator

How Probiotics Fit In

Probiotics can help shorten the duration of diarrhea, though the effect varies by strain. In a comparative trial of children with acute diarrhea, one well-studied strain (Lactobacillus rhamnosus GG) reduced the average duration of symptoms by nearly 19 hours compared to no probiotic. That’s meaningful when you’re miserable. Yogurt with live active cultures is the simplest dietary source. Fermented foods like kefir and miso are other options, though they may be harder to stomach when you’re nauseous.

Hydration Matters More Than Food

The biggest danger from diarrhea isn’t the diarrhea itself. It’s dehydration. You’re losing water and electrolytes with every trip to the bathroom, and replacing them is more urgent than eating solid food. Oral rehydration solutions are ideal because they contain the right balance of salt, sugar, and water to maximize absorption. Broth, diluted sports drinks, and coconut water also help.

Sip small amounts frequently rather than gulping large volumes, which can trigger more cramping. If your urine is dark yellow or you feel dizzy when standing, you need more fluids.

Getting Back to Normal Eating

Once you feel like eating again, you can generally return to your regular diet. There’s no strict timeline or mandatory sequence of reintroduction. Your appetite is a reasonable guide. If something sounds good and doesn’t cause a flare-up, keep eating it.

The one exception is dairy. Problems digesting lactose can persist for a month or more after a diarrheal illness, even in people who were never lactose intolerant before. If milk or cheese seems to bring symptoms back, avoid them for a few weeks and try again gradually. Yogurt and aged cheeses like cheddar and parmesan contain less lactose and are usually tolerated sooner.

High-fiber foods like beans, whole grains, and raw vegetables are worth reintroducing slowly. Start with small portions and increase over several days. Your gut flora needs time to reestablish itself, and flooding it with fiber before it’s ready can restart the cycle.
