The BRAT diet is a short-term eating plan built around four bland, low-fiber foods: bananas, rice, applesauce, and toast. It’s been used for decades as a home remedy to ease diarrhea from stomach bugs, food poisoning, and traveler’s diarrhea. The idea is simple: by eating only soft, easy-to-digest foods, you give your irritated gut less work to do while your stools firm up.
That said, medical thinking on the BRAT diet has shifted. It’s no longer considered a first-line treatment, and major health organizations now emphasize hydration and returning to a normal diet quickly over restricting food for days. Here’s what you need to know to use it safely.
What Each Food Does
The four BRAT foods share a few key traits: they’re low in fiber, easy to chew and swallow, and unlikely to irritate an already upset stomach. But each one brings something slightly different to the table.
Bananas are rich in potassium, an electrolyte you lose in large amounts during diarrhea and vomiting. They’re also naturally binding, meaning they can help add some firmness to loose stools. Rice (plain white rice, not brown) is a starchy, low-residue food. “Residue” refers to indigestible material that adds bulk to stool. White rice has very little of it, so it moves through your gut without stimulating more bowel movements. Applesauce provides gentle calories and some pectin, a type of soluble fiber that absorbs water in the intestines. Toast (plain, white bread) is another simple starch that’s easy to keep down when your stomach is sensitive.
None of these foods contain significant fat, spice, or acidity, all of which can trigger cramping or worsen diarrhea when your gut lining is inflamed.
Why Doctors No Longer Recommend It Alone
For years, the logic behind the BRAT diet was “gut rest”: the idea that your digestive system needed a break, and that restricting your diet to the blandest possible foods would speed recovery. That concept is now outdated. Randomized clinical trials have shown that refeeding immediately after rehydration actually leads to lower stool output, shorter illness duration, and better nutritional outcomes compared to gradually reintroducing food.
The American Academy of Pediatrics, the CDC, and the World Health Organization all recommend returning to a normal, age-appropriate diet as soon as you’re rehydrated. The BRAT diet, eaten exclusively for more than a day or two, simply doesn’t provide enough nutrition. It’s low in protein, fat, vitamin A, vitamin B12, calcium, and overall calories. For children especially, prolonged restriction can slow recovery rather than help it.
This doesn’t mean the BRAT foods are harmful. They’re perfectly fine to eat while you’re sick. The shift is away from eating only those four foods for days on end, and toward a broader approach that includes hydration, prompt refeeding, and variety.
Hydration Matters More Than Food Choices
The real danger of diarrhea isn’t what you eat. It’s fluid and electrolyte loss. Every watery stool pulls sodium, potassium, and water out of your body, and if you don’t replace them, dehydration sets in quickly, especially in young children and older adults.
Oral rehydration therapy is the cornerstone of diarrhea treatment for both children and adults. You can buy oral rehydration solutions at any pharmacy, or make a simple version with water, salt, and sugar. Clear broths and coconut water also help replace electrolytes. Plain water is better than nothing, but it doesn’t replace the sodium and potassium you’re losing.
Aim to take small, frequent sips rather than gulping large amounts, which can trigger nausea. If you’re vomiting alongside diarrhea, try waiting 15 to 20 minutes between sips to keep fluids down.
Foods to Avoid While Recovering
While the specific BRAT foods aren’t as important as once thought, avoiding certain trigger foods genuinely helps. The National Institutes of Health recommends steering clear of:
- High-fat foods like fried items, pizza, and fast food, which speed up intestinal contractions
- Caffeine from coffee, tea, and some soft drinks, which stimulates the bowel
- Alcohol, which is dehydrating and irritates the gut lining
- Foods high in simple sugars, including fruit juices, candy, and sweetened drinks, which can draw water into the intestines and worsen loose stools
- Sugar alcohols found in sugarless gum and candies
- Dairy products containing lactose. Some people have trouble digesting lactose for up to a month after a bout of acute diarrhea, even if they’re not normally lactose intolerant
The BRATY Variation
Some practitioners recommend a slightly expanded version called the BRATY diet, which adds yogurt to the original four foods. The logic is that plain yogurt contains live probiotic cultures that can help restore the balance of beneficial bacteria in your gut. Fermented foods like miso soup and kefir offer similar benefits.
This is one case where dairy gets a pass. Unlike milk or ice cream, yogurt’s fermentation process breaks down much of the lactose, making it easier to tolerate. If you’re going to add one food to the basic BRAT list, plain yogurt with live cultures is a practical choice.
How to Use the BRAT Diet Sensibly
Think of the BRAT foods as a starting point, not the entire plan. In the first several hours of illness, focus on staying hydrated. Once nausea subsides enough to eat, you can begin with small amounts of bland food: a few bites of banana, a small bowl of plain rice, some dry toast. These are gentle ways to test whether your stomach is ready.
Within 24 to 48 hours, start expanding your diet. Add lean proteins like baked chicken or scrambled eggs. Try boiled potatoes, plain crackers, or steamed vegetables. The goal is to get back to a nutritionally complete diet as soon as your body tolerates it. Staying on BRAT foods alone beyond two days risks leaving you short on calories and key nutrients at exactly the time your body needs fuel to recover.
For children, this timeline matters even more. Kids have smaller energy reserves and higher nutritional demands relative to their body weight. Pediatric guidelines emphasize returning to a normal diet promptly rather than restricting food choices for multiple days.
