The BRAT diet (bananas, rice, applesauce, and toast) is no longer recommended because it lacks the protein, fiber, fat, and vitamins your body needs to recover from illness. The American Academy of Pediatrics flagged it as “too restrictive” back in 1996, and current guidelines from the National Institutes of Health advise against following any restricted diet during a bout of viral gastroenteritis. The short version: the BRAT diet may firm up your stool temporarily, but it can slow your actual recovery.
How the BRAT Diet Became Standard Advice
For decades, the BRAT diet was handed out as go-to guidance for anyone with diarrhea or an upset stomach, especially children. The logic seemed sound: bland, binding foods would be gentle on an irritated gut and help solidify loose stools. Bananas replace lost potassium, white rice absorbs water in the colon, applesauce provides pectin, and toast is easy to digest. Parents passed the advice to other parents, and it became one of those medical recommendations that lived on long after the evidence moved past it.
The problem is that no clinical trials have ever been conducted to test whether the BRAT diet actually works. A review from the University of Virginia School of Medicine found that while some data exist on the individual roles of bananas and rice in managing diarrhea, the diet as a whole has never been validated. It became widespread based on intuition, not research.
The Nutritional Problem
The BRAT diet is almost entirely simple carbohydrates. It contains very little protein, almost no fat, minimal fiber, and is missing many essential vitamins and minerals. When you’re sick with gastroenteritis, your gut lining is inflamed and damaged. Repairing that lining requires all three macronutrients (protein, carbohydrates, and fat) along with adequate micronutrients. Restricting yourself to four bland foods starves your body of the building blocks it needs for recovery.
This isn’t a minor concern. The University of Virginia review warned that following a single restrictive diet like BRAT during diarrhea “can impair nutritional recovery and in fact lead to severe malnutrition.” That risk is especially serious in young children, who have smaller nutritional reserves and can become malnourished faster than adults.
Restricted Diets Can Make Diarrhea Worse
One of the more counterintuitive findings is that eating too little during a stomach illness can actually prolong symptoms rather than resolve them. When the gut receives very little food, it produces what are sometimes called “starvation stools,” watery bowel movements that continue because the intestines have nothing substantial to work with. The gut needs bulk and variety to return to normal motility.
Fiber plays a particularly important role here. Soluble fiber helps protect and repair the intestinal lining by supporting the mucus layer that shields gut cells from further damage. Animal research has shown that soluble fiber supplementation during illness increases the thickness of this protective mucus, reduces inflammation, and boosts populations of beneficial gut bacteria. The BRAT diet, built around refined white rice and white bread, is nearly devoid of fiber.
What Doctors Recommend Instead
Current guidelines from the National Institute of Diabetes and Digestive and Kidney Diseases are straightforward: eat what you normally eat as soon as your appetite returns. For children, parents should offer their usual foods. Infants should continue breast milk or formula as normal. The emphasis has shifted from restriction to prompt refeeding with a balanced diet.
That doesn’t mean you need to force down a heavy meal while nauseous. It means that once you feel ready to eat, you should choose from a normal range of foods rather than limiting yourself to four items. Lean proteins like chicken or eggs, cooked vegetables, yogurt, and whole grains all provide nutrients the BRAT foods don’t. If bananas, rice, applesauce, or toast sound appealing, they’re fine to include. They just shouldn’t be the only things you eat.
Cleveland Clinic gastroenterologists acknowledge that the BRAT foods can help firm up stool in the short term, so using them for a day or two alongside other foods isn’t harmful. The issue is treating the BRAT diet as a complete recovery plan for several days, which is when nutritional gaps become a real problem.
Hydration Matters More Than Food Choices
The biggest risk during gastroenteritis isn’t what you eat. It’s dehydration. Replacing lost fluids and electrolytes is the single most important part of recovery. Oral rehydration solutions, which balance glucose and sodium to maximize water absorption, are the standard recommendation for preventing and treating dehydration.
Fruit juices and soft drinks are generally discouraged because their high sugar content and low sodium can worsen diarrhea and, in some cases, cause dangerously low sodium levels. There is one exception worth noting: a study published in The Journal of Pediatrics found that diluted apple juice followed by the child’s preferred fluids worked better than standard electrolyte solutions in children over two years old with mild dehydration. This applied specifically to older children in well-resourced settings with minimal dehydration, not to severe cases or infants.
For most adults, water, broth, and oral rehydration drinks are sufficient. Small, frequent sips work better than large amounts at once if nausea is still present.
Why the Advice Persists
The BRAT diet remains one of the most commonly Googled remedies for stomach illness despite being officially discouraged for nearly three decades. Part of this is generational: parents who were told to use it in the 1980s and 1990s pass the advice to their own children. Part of it is that the diet does provide some symptomatic relief, making stools firmer, which feels like improvement even if it isn’t speeding healing.
The core message from current medical guidance is simple. Prompt refeeding with a normal, balanced diet gives your body what it needs to repair itself. Restricting food to a handful of bland, low-nutrient items does the opposite. If the BRAT foods appeal to you when you’re sick, eat them, but add protein, healthy fats, and variety as soon as you can tolerate it.
