When you have food poisoning, the priority is fluids first, then small amounts of bland food once vomiting has settled. Your digestive tract is inflamed and irritated, so the goal is to give it the least amount of work possible while keeping you hydrated and nourished enough to recover. Most cases resolve within one to three days, and what you eat during that window can make a real difference in how you feel.
Start With Fluids, Not Food
Dehydration is the biggest immediate risk from food poisoning, especially if you’re dealing with both vomiting and diarrhea. Before you think about eating anything solid, focus on replacing the water and electrolytes you’re losing. Take small, frequent sips rather than gulping a full glass, which can trigger more vomiting.
Plain water works, but it doesn’t replace the sodium and potassium your body is flushing out. A simple homemade rehydration drink does: mix 4 cups of water with half a teaspoon of table salt and 2 tablespoons of sugar. That combination helps your intestines absorb fluid more efficiently than water alone. Commercial electrolyte drinks and coconut water are also reasonable options. Coconut water is naturally high in potassium, though it’s lower in sodium than most electrolyte drinks, so it’s not a perfect swap on its own.
Avoid coffee, caffeinated tea, and soft drinks with caffeine. Caffeine can stimulate your gut and make diarrhea worse at a time when your intestines are already in overdrive.
When to Try Solid Food
There’s no strict hour count to follow. The general rule is to wait until vomiting has stopped and you feel ready to nibble. For some people that’s a few hours; for others it’s a full day. Don’t force food down if the thought of eating still turns your stomach. Your body is telling you something useful.
When you do start, keep portions tiny. A few bites of plain toast or a small bowl of white rice is enough for your first attempt. If that stays down comfortably, you can gradually increase the amount over the next several meals.
Best Foods During Recovery
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a fine starting point for the first day or two, but there’s no clinical evidence that restricting yourself to only those four foods speeds recovery. A broader range of bland, easy-to-digest foods is just as safe and gives your body more of the protein and nutrients it needs to heal.
Good options include:
- Simple starches: white rice, plain crackers, boiled or baked potatoes, oatmeal, refined pasta
- Gentle proteins: skinless chicken or turkey, baked white fish, eggs, tofu
- Soft fruits and vegetables: bananas, applesauce, canned fruit, cooked carrots, cooked squash (butternut or pumpkin), avocado
- Comforting liquids: clear broth, chicken noodle soup, weak tea, gelatin, popsicles
The common thread is low fat, low fiber, and minimal seasoning. These foods move through your digestive system without demanding much effort from your already-stressed gut lining. As you feel better over the following days, you can reintroduce your normal diet gradually.
Foods That Will Make You Feel Worse
Some foods actively aggravate an inflamed digestive tract. Greasy, fried, and high-fat foods like pizza, fast food, and anything deep-fried are harder to break down and can worsen nausea and diarrhea. Spicy foods irritate the gut lining further.
Dairy deserves special attention. Food poisoning can temporarily damage the cells in your intestinal lining that produce lactase, the enzyme you need to digest milk sugar. This means milk, cheese, ice cream, and other dairy products may cause bloating, cramps, and diarrhea even if you normally tolerate them fine. This temporary lactose sensitivity can last a month or longer after the infection clears, so it’s worth reintroducing dairy slowly.
Alcohol is another one to skip entirely. It’s dehydrating, irritating to the gut, and adds zero nutritional value when your body is trying to recover.
Ginger for Nausea
If nausea is your main barrier to eating, ginger is one of the most studied natural remedies and it genuinely works for many people. You don’t need a supplement. A cup of ginger tea, a teaspoon of freshly grated ginger steeped in hot water, or a couple of pieces of crystallized ginger can help settle your stomach enough to tolerate small bites of food. Clinical studies on nausea from various causes have used daily doses ranging from about 500 mg to 1,500 mg of ginger powder, roughly equivalent to one to two teaspoons of fresh grated ginger root.
Rebuilding Your Gut After Infection
Food poisoning doesn’t just pass through your system. It disrupts the balance of bacteria in your gut, and restoring that balance can help you recover faster. The probiotic strain Lactobacillus rhamnosus GG (often labeled LGG on packaging) has the strongest evidence for shortening bouts of infectious diarrhea, reducing both severity and duration by roughly one day. The American Academy of Pediatrics specifically supports its use early in the course of acute infectious diarrhea. You can find LGG in certain yogurt brands and in supplement form sold at most pharmacies.
Beyond supplements, fermented foods like plain yogurt (once you’re tolerating dairy again), kefir, and miso can help repopulate beneficial bacteria. Just introduce them after the worst symptoms have passed, not during active vomiting.
Signs Your Food Poisoning Needs Medical Attention
Most food poisoning resolves on its own, but certain symptoms signal something more serious. The CDC identifies these as red flags: bloody diarrhea, diarrhea lasting more than three days, a fever above 102°F, vomiting so frequent that you can’t keep any liquids down, and signs of dehydration like not urinating much, a dry mouth and throat, or dizziness when you stand up. These warrant a call to your doctor or a trip to urgent care, particularly in young children, older adults, pregnant women, and anyone with a weakened immune system.
