Plain white rice can help settle your stomach, especially during bouts of diarrhea, nausea, or general digestive upset. It’s one of the easiest foods for your body to break down: your stomach fully processes a serving of white rice in about 30 minutes. That quick, low-effort digestion is exactly why rice has been a go-to remedy for centuries and remains a staple recommendation for short-term stomach trouble.
That said, the old advice to eat nothing but rice, bananas, applesauce, and toast (the BRAT diet) for days on end is outdated. Here’s what actually works, and why.
Why White Rice Is Easy on Your Stomach
White rice is refined, meaning the outer bran layer has been stripped away. What’s left is mostly soft starch with very little fiber, fat, or protein to slow things down. Your digestive enzymes can access and break apart that starch rapidly, so the rice moves through your stomach without forcing it to churn hard or produce excess acid. For a stomach that’s already irritated from vomiting, infection, or food poisoning, that gentleness matters.
White rice is also considered a “binding” food. Because it absorbs water in the gut and produces relatively little residue, it can help firm up loose stools during diarrhea. It won’t cure the underlying cause, but it gives your digestive tract something easy to work with while it recovers.
The BRAT Diet Still Has a Place, but a Small One
Rice is the “R” in the BRAT diet (bananas, rice, applesauce, toast), which was once the standard medical advice for any stomach bug. That’s changed. The American Academy of Pediatrics no longer recommends a strict BRAT diet for children with diarrhea because it’s too low in calories, protein, and fat to support recovery. Following it for more than 24 hours may actually slow healing in kids.
For adults, the Cleveland Clinic still considers BRAT foods useful as a starting point, particularly for a day or two when diarrhea strikes during travel or when you don’t have access to medical care. The key shift in advice is this: use rice and other bland foods to get something in your stomach, but don’t limit yourself to only those foods for more than a day. As soon as you can tolerate it, reintroduce a wider range of nutrients so your body has what it needs to heal.
White Rice vs. Brown Rice for Stomach Trouble
If your stomach is upset, white rice is the better choice. Brown rice still has its bran layer intact, and research on human subjects shows that brown rice delays gastric emptying compared to white rice, regardless of the specific variety. That slower emptying is driven by the physical presence of the bran, which your stomach has to work harder to break down.
When your digestive system is already struggling, slower stomach emptying can make nausea worse and add to feelings of fullness or bloating. Brown rice also contains more fiber, which can irritate an inflamed gut lining. Save brown rice for when you’re feeling well. It’s the healthier option day to day, and Johns Hopkins Medicine recommends whole grains like brown rice for managing acid reflux over the long term, since fiber helps prevent overeating. But in the middle of a stomach bug, white rice is your friend.
Rice Variety Matters More Than You’d Think
Not all white rice digests at the same speed. The difference comes down to the ratio of two types of starch inside each grain. Rice with less of a starch called amylose (like sticky jasmine or sushi rice) tends to be softer, stickier, and faster to digest. Rice with more amylose (like basmati or long-grain varieties) is firmer and digests a bit more slowly because the starch granules don’t swell as much, making it harder for digestive enzymes to do their work.
For settling your stomach quickly, stickier, lower-amylose varieties like jasmine or short-grain white rice are the gentlest option. Basmati is still easy to digest compared to most foods, but it sits in the stomach slightly longer.
Congee: The Most Stomach-Friendly Way to Eat Rice
If even plain steamed rice feels like too much, congee (rice porridge) is a step gentler. It’s made by cooking rice in five or more times the usual volume of water on low heat for several hours until the grains break down completely into a silky, soupy consistency. The result is exceptionally easy to digest because the starch is already partially broken apart before it reaches your stomach.
Congee also helps with hydration, which is critical during vomiting or diarrhea. The high water content delivers fluid along with easily absorbed calories. This is why congee has been used across Asian cultures for centuries as a first food for babies, nursing mothers, and anyone recovering from illness. A basic version made from white rice, water, and a pinch of salt is all you need when your stomach is at its worst. You can add ginger for nausea or a small amount of broth for flavor as you start feeling better.
Rice water, the starchy liquid left over after cooking rice, works on the same principle. Sipping it provides hydration and a small amount of easily absorbed energy without requiring your stomach to break down any solid food at all.
Cooled Rice Has Different Effects
Here’s something worth knowing if you’re eating rice regularly for gut health rather than acute stomach trouble. When cooked rice is cooled in the refrigerator, some of its starch converts into what’s called resistant starch. This type of starch passes through your small intestine undigested and reaches your large intestine, where gut bacteria ferment it and produce compounds called short-chain fatty acids that support colon health.
Each day rice spends chilled after cooking increases its resistant starch content, with the effect building over about four days. This is great for long-term gut health, but it’s not what you want when your stomach is actively upset. Resistant starch can cause gas and bloating in a sensitive gut. When you’re recovering, eat your rice freshly cooked and warm.
How to Use Rice When Your Stomach Is Upset
Start small. A half-cup of plain white rice is enough to test whether your stomach can handle solid food. Eat it plain or with just a pinch of salt. Avoid adding butter, oil, soy sauce, or spices until your symptoms improve, since fat and strong flavors can trigger nausea or worsen diarrhea.
If you’re vomiting, wait until you’ve kept clear liquids down for a few hours before trying rice. Congee or rice water can bridge the gap between liquids and solid food. If you have diarrhea but aren’t vomiting, you can start with rice right away.
After a day or two of bland eating, begin adding back other foods: lean protein like plain chicken, cooked vegetables, and broth-based soups. Your gut lining repairs itself using protein and micronutrients that rice alone can’t provide, so expanding your diet quickly supports faster recovery.
A Note on Eating Rice Frequently
Rice is safe to eat regularly for most adults, but it does accumulate trace amounts of arsenic from soil and water. This is generally not a concern at normal consumption levels. For young children and infants, however, safety thresholds are lower. Research suggests infants under one year should consume no more than about 32 grams of rice products per week to minimize long-term risk. Adults have a much higher threshold (around 243 grams per week in the most conservative estimates), but if you find yourself relying on rice daily for ongoing digestive issues, it’s worth varying your bland-food rotation with options like oatmeal, plain potatoes, or toast.
