After food poisoning, your gut needs a short reset before you return to normal eating. The first priority is replacing lost fluids, then gradually reintroducing easy-to-digest foods as your stomach settles. Most people can return to their regular diet within one to three days, though the exact timeline depends on how severe the episode was.
A Simple Timeline for Getting Back to Food
In the first zero to six hours after symptoms start, stick to ice chips or popsicles. Your stomach is at its most irritated, and trying to eat or drink too much too fast will likely come right back up. Once vomiting has stopped and you’re keeping ice chips down, move on to sipping clear liquids: water, broth, diluted juice, or an oral rehydration solution.
After roughly 24 hours without vomiting, you can start eating bland, soft foods. This isn’t a rigid schedule. If you feel ready sooner, go ahead. But if you can’t keep even water down after six hours, that’s a signal to contact your doctor.
Hydration Comes First
Vomiting and diarrhea drain your body of water and electrolytes fast. Plain water helps, but it doesn’t replace sodium and potassium. Oral rehydration solutions (sold at most pharmacies) work better because they contain a specific balance of salt and glucose that helps your intestines absorb water more efficiently. The optimal formula uses a 1:1 ratio of sodium to glucose, which activates a transport mechanism in your gut lining that pulls water in alongside those molecules.
If you don’t have a rehydration solution on hand, clear broth is a decent stand-in because it contains sodium. Coconut water provides potassium. Avoid sugary drinks like soda, sports drinks with high sugar content, and undiluted fruit juice. High concentrations of simple sugar can actually pull water into your intestines and make diarrhea worse.
Best Foods for the First Few Days
You’ve probably heard of the BRAT diet (bananas, rice, applesauce, toast), and those foods are fine starting points. But most experts no longer recommend limiting yourself strictly to those four items. The goal is simply to choose foods that are low in fiber, low in fat, and gentle on your digestive system. A wider range of bland foods gives you more calories and nutrients to support recovery.
Good options include:
- White rice and plain pasta
- Saltine crackers or white toast
- Bananas and applesauce
- Canned or well-cooked potatoes, carrots, and green beans
- Plain chicken or fish (baked or boiled, not fried)
- Eggs
- Low-fiber cereals (look for less than 2 grams of fiber per serving)
- Canned peaches or melon
Look for foods with no more than 1 to 2 grams of fiber per serving. Fiber is normally beneficial, but it speeds food through your gut, which is the opposite of what you need when diarrhea is still a problem. As your stools firm up, gradually add back your normal foods over two to three days.
Foods and Drinks to Avoid
Some foods actively slow recovery or make symptoms worse. Steer clear of these until you’re fully back to normal:
- Dairy products. Food poisoning can temporarily damage the cells in your intestinal lining that produce lactase, the enzyme that digests lactose in milk. This creates a short-term lactose intolerance that causes bloating, gas, and more diarrhea. The effect is transient and resolves as your gut heals, but avoiding milk, ice cream, and soft cheese for a few days prevents unnecessary discomfort. Yogurt is usually better tolerated because fermentation breaks down some of the lactose.
- Fatty and fried foods. Fat slows stomach emptying and is harder to digest when your gut lining is inflamed. Greasy meals can trigger nausea and cramping.
- Spicy foods. Capsaicin irritates an already sensitive stomach and can worsen cramping.
- Caffeine. Coffee and energy drinks stimulate gut motility, pushing contents through your intestines faster and worsening diarrhea.
- Alcohol. It irritates the stomach lining and acts as a diuretic, compounding dehydration.
- High-fiber foods. Raw vegetables, whole grains, beans, and nuts are hard to break down when your digestive system is compromised.
- Sugary drinks and candy. High concentrations of simple sugars draw water into the intestines, which can increase diarrhea output.
If you smoke or use nicotine products, consider pausing during recovery. Nicotine increases stomach acid production and gut motility while reducing blood flow to the stomach lining and suppressing the protective mucus layer. All of those effects work against healing.
Probiotics Can Shorten Recovery
A specific probiotic strain called Lactobacillus rhamnosus GG (often labeled LGG on supplement packaging) has solid evidence behind it for shortening diarrhea. A meta-analysis of trials involving nearly 1,000 children found it reduced diarrhea duration by about one day on average, with even larger reductions for certain viral infections. The effective dose is at least 10 billion colony-forming units (CFU) per day, taken for five to seven days. Starting sooner improves results.
While most of this research was done in children, the mechanism applies broadly. Look for supplements that list the specific strain and CFU count on the label. Yogurt with live cultures provides some probiotics but typically at much lower concentrations than a targeted supplement.
Feeding Kids After Food Poisoning
Children follow the same general principles, with a few important differences. CDC guidelines emphasize that withholding food for more than 24 hours is inappropriate for children, and “gut rest” is not recommended. The goal is to return kids to their normal, age-appropriate diet as quickly as possible.
Breastfed babies should continue nursing throughout the illness, even during the rehydration phase. Formula-fed infants should go back to their usual formula immediately after rehydration, and switching to a lactose-free formula is usually unnecessary. For older children eating solid foods, continue offering their regular diet during diarrhea episodes. Complex carbohydrates, meats, yogurt, fruits, and vegetables are all recommended.
Be especially careful with sugar-heavy liquids for kids. Soda, juice, and gelatin desserts contain enough simple sugar to worsen diarrhea. Pediatric oral rehydration solutions are specifically formulated with lower sugar and appropriate sodium levels. For young children, no wet diapers for three or more hours is a warning sign of dehydration that needs medical attention.
How to Know You’re Ready for Normal Eating
Your body will tell you. When nausea has passed, you’re keeping liquids down easily, and your stools are starting to return to normal consistency, you can begin expanding your diet. Most people move through the full progression, from ice chips to bland foods to regular meals, within 24 to 72 hours.
Don’t force yourself to eat if you’re still nauseated, but don’t starve yourself either. Your intestinal lining needs energy to repair, and calories from easy-to-digest foods support that process. Eat small, frequent portions rather than large meals. If a food makes you feel worse, back off and try again the next day.
