What to Eat When You Have Diarrhea: Diet Tips That Help

You’ve probably wondered what to eat when you have diarrhea. It feels like your digestive system has completely lost its natural rhythm. Sometimes it’s triggered by a bacterial infection, sometimes food poisoning, and other times it’s just stress management or something you ate that didn’t sit right. And while bouts of diarrhea usually pass, the way you choose what to eat when you have diarrhea during recovery can make your symptoms worse—or help calm things down.

Food doesn’t magically cure loose bowel movements, but it does give your body a chance to absorb fluids, replace lost electrolytes, and settle into balance again. And honestly, that’s all you want when your stomach’s rebelling: a bit of comfort, a sense that things are moving back toward normal.

So, instead of thinking of a diarrhea diet plan as a punishment (bland foods, plain rice, no fun), it might help to see it as a short reset. Something that soothes the digestive system, keeps you hydrated, and—if you’re patient—gets you back on track faster.

First Things First: Hydration Is Key

It’s not the most exciting advice, but hydration is where everything starts when you’re figuring out what to eat when you have diarrhea. Honestly, it’s not even about food at first—it’s about replacing the cup of liquid you keep losing with every trip to the bathroom. The body can only do so much with poor digestion if it doesn’t have fluids to work with.

Best fluids to drink

Here’s the rule of thumb: stick to fluids that help your body absorb water instead of flushing it out.

• Plain water (obvious, but crucial).
  
• Electrolyte drinks like Pedialyte or other over-the-counter medications in liquid form. If you don’t have those, even homemade oral rehydration solutions (ORS)—a mix of clean water, salt, and a little sugar—can be surprisingly effective.
  
• Clear broths (a salty broth works double duty: hydration plus sodium to help with electrolyte balance).
  
• Herbal teas like chamomile or peppermint, which sometimes feel soothing when your digestive system is unsettled.
  
• Coconut water, which naturally contains electrolytes, though some people find the sweetness a bit much.
  

A quick side note: Children with diarrhea are especially at risk of dehydration, and doctors often recommend ORS first. Adults sometimes forget the same principle applies to them too.

What fluids to avoid?

It’s tempting to reach for whatever’s in the fridge, but certain drinks can make diarrhea symptoms worse. Best to skip:

• Caffeinated drinks (coffee, black tea, energy drinks).
  
• Drink Alcohol (it’s dehydrating and rough on the stomach).
  
• Sugary sodas (all that simple sugar can pull more water into your intestines).
  
• Dairy-heavy shakes or smoothies (lactose-containing foods are often harder to digest during these episodes).
  

Pro tip: A good check is to sip small amounts—say, half a cup of liquid every 15–20 minutes—instead of chugging a full glass. Your digestive system will thank you for the slow pace.

The BRAT Diet: Still Useful or Outdated?

You’ve probably heard of the BRAT diet before—bananas, rice, applesauce, and toast. It’s the old-school answer to what to eat when you have diarrhea. Doctors used to recommend it across the board because these foods are plain, low-fiber, and easy on the digestive system. Honestly, it makes sense: when every loose bowel movement leaves you drained, the last thing you want is raw vegetables or fried food sitting heavy in your stomach.

Why do these foods help?

• Bananas: Gentle on the stomach, plus they replace potassium lost through diarrhea.
  
• Rice (white rice especially): Bland and binding—helps firm up stool.
  
• Applesauce: Provides pectin, a type of soluble fiber, that slows digestion without irritating your gut.
  
• Toast (white bread, not whole grain): A safe source of refined grains that won’t trigger poor digestion.
  

Together, these foods reduce the workload on your gut and give it space to recover. They won’t fix an imbalance of bacteria on their own, but they make symptoms easier to manage.

Updated perspective

Here’s where it gets interesting: what to eat when you have diarrhea, most health professionals now see the BRAT diet as a starting point, not the full solution. On its own, it doesn’t provide enough protein, healthy fats, or vitamins. So the modern approach looks more like BRAT-plus—still leaning on bland foods, but gradually adding in other gentle options like oatmeal, Cream of Wheat, or even plain sweet potatoes.

Pro tip: Think of BRAT foods as your “safe zone.” Stick with them for the first 24 hours, then slowly add variety as your stomach allows.

Gentle, Binding Foods That Soothe Your Stomach

If you’re beyond the initial rough patch, you might be ready to try a few other gentle foods. The idea is the same: stick to things that are easy to digest, binding (they help reduce watery stool), and not packed with irritants.

Here’s a quick table of diarrhea-friendly foods and why they work:

Food	Why it Helps	Notes
White rice	Low-fiber, binding	Skip sauces or spices
Oatmeal / Cream of Wheat	Soft texture, soluble fiber	Add a pinch of salt, not sugar
Potatoes (boiled, baked, or mashed without toppings)	Starchy and filling	Avoid butter or heavy cream
Applesauce	Contains pectin, soothing	Better than raw apples
Plain crackers or white bread	Simple, refined grains	Easy on the stomach
Ripe bananas	Replace electrolytes	Stick to fully ripe, not green

And while this sounds restrictive, it’s really just a temporary phase. Some people even find plain sweet potatoes gentler than white ones, though that varies depending on your digestive system.

A small caution: even foods that look “safe” can be tricky if you’re dealing with Irritable Bowel Syndrome. For example, potatoes without toppings are fine, but add butter or cheese, and you might be back in the bathroom faster than you’d like.

Side note: When I was traveling once, I had a mild bout of food poisoning and lived on plain crackers, applesauce cups, and electrolyte-enhanced water for two days. Not the most glamorous diet, but I remember how grateful I felt for something my body could actually handle.

Foods Rich in Soluble Fiber

One thing people don’t always expect is that some fiber can actually help with bouts of diarrhea. Not the rough, scratchy kind you find in raw vegetables or heavy meals, but soluble fiber—the gentle kind that absorbs water and slows things down a bit in your digestive system. It helps firm up stool so your body can absorb nutrients instead of pushing everything through too quickly.

Examples of soluble fiber foods that work when you’re figuring out what to eat when you have diarrhea:

• Oats and Cream of Wheat – soft, warm, and easy to eat in small frequent meals.
  
• Cooked carrots or peeled apples – far easier on your gut than raw vegetables or citrus fruits.
  
• Psyllium husk – you’ll sometimes see it in home treatments or supplements, and it’s especially good for loose bowel movement recovery.
  
• Pears (peeled and soft) – mild, not too acidic, and comforting.
  

Pro tip: introduce soluble fiber gradually. Too much at once can leave you bloated, which is basically the last thing you want when diarrhea symptoms are already dragging you down. Think of it as gently coaxing your digestive system back into its natural rhythm instead of rushing it.

Probiotics: Restoring Gut Balance

Here’s something that feels almost counterintuitive: during diarrhea, especially if it’s caused by a bacterial infection, your gut bacteria get thrown out of balance. That imbalance of bacteria can stick around even after the viral infection or food poisoning passes. Which is where probiotics—either through food or probiotic supplements—step in.

Natural probiotic foods

• Yogurt with live cultures (as long as you’re not struggling with lactose-containing foods at the moment).
  
• Kefir, another fermented milk option, though again, only if your stomach tolerates it.
  
• Miso soup, sauerkraut, or other fermented foods, which can support recovery if added carefully after the worst has passed.
  
• Probiotic foods in capsule form for people who can’t handle dairy or fermented flavors.
  

Probiotic supplements

Sometimes it’s not practical to rely on food alone. If you’ve taken diarrheal medication or over-the-counter medications like antibiotics recently, probiotic supplements can help rebuild gut diversity. The strains most often recommended are Lactobacillus and Bifidobacterium, which research suggests may reduce future diarrhea symptoms and help the body to absorb nutrients better.

One little caution, though: probiotics aren’t instant. They work with time, kind of like planting seeds. If you expect them to fix a loose bowel movement overnight, you might be disappointed. But give them a week or two, and they can make a noticeable difference in restoring balance.

Foods to Avoid When You Have Diarrhea

Sometimes knowing what not to eat is just as important as learning what to eat when you have diarrhea. Certain foods can make symptoms worse by irritating the digestive system, pulling water into the intestines, or just being plain hard to digest.

Here’s a quick breakdown of the usual culprits:

• Fried or fatty food – greasy meals slow digestion and can increase loose bowel movement.
  
• Spicy foods – chili, curry, or pepper-heavy meals often make diarrhea symptoms worse.
  
• High-fiber raw vegetables – salad might sound healthy, but raw vegetables can be too harsh on an already inflamed gut.
  
• Dairy products – if you’re temporarily sensitive to lactose-containing foods, even a small amount of milk or cheese can trigger poor digestion.
  
• Artificial sweeteners – things like sorbitol and mannitol (often found in “sugar-free” gums or candies) can act like natural laxatives.
  
• Citrus fruits – oranges, grapefruits, or juice with a lot of acid may irritate your stomach lining.
  
• Alcohol and caffeine – both pull water out of the body, worsening dehydration.
  

Pro tip: When in doubt, follow this simple rule of thumb—avoid trigger foods that are spicy, fatty, or very high in fiber until your body has had a chance to recover.

Sample Diarrhea-Friendly Meal Plan

Sometimes it’s easier to see the whole day laid out instead of guessing meal by meal. This is not a strict prescription—just a sample to give you an idea of how gentle, frequent meals might look.

Meal	Example Foods	Why It Works
Breakfast	Oatmeal made with water, topped with half a banana	Warm, bland, adds soluble fiber and potassium
Mid-Morning Snack	Applesauce or a few plain crackers	Easy to digest, BRAT diet friendly
Lunch	White rice with boiled carrots or plain chicken broth	Binding, hydrating, adds electrolytes
Afternoon Snack	Cup of electrolyte-enhanced water + soft pear (peeled)	Replaces fluids, gentle soluble fiber
Dinner	Baked potato (plain, no toppings) with a small piece of skinless chicken	Starchy, light protein, avoids fried or fatty food
Evening	Herbal tea (chamomile or peppermint)	Calms the stomach, promotes hydration

Notice how everything is light, bland, and mostly made of refined grains or cooked fruits and vegetables. No heavy meals, no fried food, and no simple sugars like desserts.

Side note: When I tried this approach after a bout of food poisoning, I remember how comforting it felt to sip salty broth instead of forcing myself to eat a full plate of food. Small, frequent meals felt much kinder to my body than the idea of “three square meals.”

Special Considerations for Children and Older Adults

Managing diarrhea isn’t one-size-fits-all. Children with diarrhea, for instance, can lose fluids frighteningly fast. Their smaller bodies just don’t have the same reserves, so dehydration becomes a bigger danger. For kids, plenty of fluids—ideally oral rehydration solutions (ORS) or electrolyte-enhanced water—should be your starting point. A cup of liquid every little while is more effective than one big drink.

For children, keep in mind:

• Offer safe BRAT foods (bananas, rice, applesauce, toast).
  
• Avoid sugary juices or sodas, since simple sugars can make symptoms worse.
  
• If diarrhea lasts more than 24 hours or includes a high fever, talk to a pediatrician.
  

Now, older adults face a different set of risks. Their bodies don’t always signal thirst clearly, and if they’re on medications—especially ones for blood pressure or heart health—fluid balance can get complicated. Combine that with a possible bacterial infection or viral infection, and it’s easy to see how a simple case of diarrhea can escalate.

For older adults, a few careful steps:

• Stick with bland foods like white potatoes or refined grains until digestion stabilizes.
  
• Pair liquids with salty broth to help with sodium balance.
  
• Keep an eye out for medication interactions with diarrheal medication or over-the-counter medications.
  
• Don’t wait too long to see a doctor if diarrhea symptoms persist.
  

Pro tip: For both kids and older adults, think “little and often.” Frequent meals or small sips of fluids help the body to absorb nutrients better than forcing large portions at once.

When to See a Doctor?

Most of the time, home treatments—hydration, bland foods, maybe a probiotic—are enough. But sometimes, diarrhea is a signal of something more serious, whether it’s food poisoning, an imbalance of bacteria, or another underlying issue like Irritable Bowel Syndrome.

Here are some warning signs you shouldn’t ignore:

• Persistent diarrhea lasting more than 2–3 days.
  
• High fever (over 102°F / 39°C).
  
• Bloody stools or black, tar-like stools.
  
• Severe dehydration: dizziness, confusion, very dry mouth, little or no urination.
  
• Children with diarrhea who aren’t keeping fluids down.
  
• Older adults or people with chronic conditions who experience sudden weight loss or weakness.
  

Sometimes, it’s not just about the diarrhea itself but about what it’s doing to the rest of your body. If dehydration sets in, or if there’s an underlying bacterial infection that needs strongest natural antibiotics, waiting it out could actually make symptoms worse.

Pro tip: A general rule of thumb—if your diarrhea is paired with severe pain, blood, or lasts more than a few days, get checked. Even if it turns out to be nothing serious, peace of mind is worth it.

Long-Term Gut Health: Preventing Recurrence

Once you’ve gotten through the rough patch, the focus shifts from what to eat when you have diarrhea to how to keep your digestive system steady afterward. Because the truth is, the gut doesn’t bounce back overnight. If you push too hard with heavy meals or trigger foods right away, you may find yourself back in that cycle of poor digestion.

Here are some gentle strategies for rebuilding balance:

• Reintroduce normal foods slowly – Start with bland foods like refined grains, white bread, and potatoes without toppings before moving on to more complex meals.
  
• Keep a food diary – Jot down what to eat when you have diarrhea and how your stomach reacts. It helps identify and avoid trigger foods that consistently cause issues, whether that’s citrus fruits, fried or fatty food, or dairy.
  
• Add probiotic foods and supplements – Yogurt with live cultures, sauerkraut, or probiotic supplements can help repair the imbalance of bacteria after a bacterial infection or viral infection.
  
• Stay hydrated with the right drinks – Stick with water, salty broth, or low-sugar fruit juice over sodas or alcohol. Electrolyte drinks are useful if you feel drained.
  
• Maintain frequent meals – Instead of heavy meals, choose smaller portions spaced throughout the day to support digestion.
  

Pro tip: Think of recovery as a gradual rebalancing. Your body has a natural rhythm, and pushing it too quickly—say, jumping from applesauce straight to fried chicken—can easily make diarrhea symptoms worse again.

Final Thoughts

So, what’s the takeaway? When you’re figuring out what to eat when you have diarrhea, it’s less about following strict rules and more about listening to your body. Hydration comes first—plenty of fluids, whether plain water or electrolyte-enhanced water. Then, bland foods like white rice, bananas, or potatoes without toppings give your digestive system space to calm down.

Once you’re steady, soluble fiber and probiotic foods help restore balance and prevent loose bowel movement from returning. And yes, you’ll want to steer clear of fried or fatty food, raw vegetables, and simple sugars until your gut is ready. Children with diarrhea, older adults, or anyone with severe symptoms should be especially cautious—and never hesitate to seek medical care if the warning signs stack up.

At the end of the day, recovery isn’t just about surviving a few uncomfortable hours. It’s about gently helping your body to absorb nutrients again, restoring energy, and setting yourself up so the next episode doesn’t catch you off guard. With a little patience and some careful food choices, you’ll get back to your normal rhythm sooner than you think.
