When you have food poisoning, your first priority is fluids, not food. Most people can’t keep solid food down in the first several hours anyway, and that’s fine. Once vomiting slows and you feel ready, the goal is bland, easy-to-digest foods that give your body nutrients without further irritating your gut. The old advice to stick strictly to bananas, rice, applesauce, and toast (the BRAT diet) is outdated. You can eat a wider range of gentle foods, and you should, because your body needs the nutrition to recover.
Start With Fluids, Then Ease Into Food
The biggest risk from food poisoning isn’t the infection itself. It’s dehydration from vomiting and diarrhea. Before thinking about food, focus on replacing what you’re losing. Small, frequent sips of water, clear broth, or an oral rehydration solution work best. Drinking too much at once can trigger more vomiting, so pace yourself.
Signs that dehydration is becoming serious include dark yellow or brown urine, dizziness when you stand up, a dry mouth that stays dry even after sipping water, and confusion or extreme fatigue. If you notice these, you may need medical help to rehydrate.
Once you can keep fluids down for a few hours without vomiting, you’re ready to try small amounts of solid food.
What to Eat in the First 24 Hours
Keep meals small and simple. You’re not trying to eat a full plate. A few bites every couple of hours is enough to start. The best early foods are soft, low in fat, and low in fiber. Think plain white rice, dry toast, plain crackers, or a small bowl of broth-based soup. These are easy for your stomach to process and unlikely to trigger another round of nausea.
Bananas are a good early choice because they’re gentle on the stomach and replace potassium, an electrolyte you lose through vomiting and diarrhea. Applesauce works for the same reason. But you don’t need to limit yourself to just these foods. The Cleveland Clinic notes that the strict BRAT diet lacks essential nutrients, and following it for more than 24 hours can actually slow recovery, especially in children. The American Academy of Pediatrics no longer recommends it as a treatment plan.
Adding Protein and More Nutrition
As soon as your stomach starts to settle, even partially, you can begin adding more nutritious foods. Scrambled eggs, skinless chicken or turkey, and cooked vegetables are all reasonable next steps. The key is that they’re still soft, bland, and low in fat. Baked or boiled chicken is easier on your gut than fried. Steamed carrots or squash are better choices than raw salad.
Protein matters during recovery. Your body uses it to repair the intestinal lining that food poisoning damages. Plain chicken and eggs are two of the easiest protein sources to digest. Cook them simply, without butter, oil, or heavy seasoning. If even these feel too heavy, plain bone broth provides some protein and amino acids in liquid form.
Foods to Avoid Until You’re Better
Some foods will make your symptoms noticeably worse. Dairy is one of the biggest culprits. Food poisoning can temporarily damage the cells lining your small intestine, and those cells are where your body produces the enzyme that breaks down lactose (the sugar in milk). Without enough of that enzyme, undigested lactose pulls extra water into your intestines and gets fermented by gut bacteria, producing gas, bloating, cramping, and more diarrhea. This temporary lactose intolerance can last days to weeks after the initial illness, even after you otherwise feel better.
Other foods to skip during recovery:
- Fatty or fried foods: Fat slows digestion and can trigger nausea when your stomach is already irritated.
- Spicy foods: These can further inflame your gut lining.
- High-fiber foods: Raw vegetables, whole grains, beans, and nuts are normally healthy, but right now they can cause gas, bloating, and cramping. Your digestive tract needs time to heal before handling roughage again.
- Caffeine and alcohol: Both are dehydrating, which is the opposite of what your body needs. Caffeine also stimulates your intestines, which can worsen diarrhea.
- Sugary drinks and fruit juice: High sugar content can draw water into the intestines and make diarrhea worse.
Ginger for Nausea
Ginger has solid evidence behind it as a nausea remedy, particularly for pregnancy and chemotherapy-related nausea. For food poisoning, it won’t treat the underlying cause, but it can take the edge off that queasy feeling enough to help you start eating. Ginger tea, made by steeping a few slices of fresh ginger root in hot water, is the simplest way to try it. Ginger chews or flat ginger ale (stir out the carbonation first) are other options. Avoid ginger supplements in capsule form on an empty, irritated stomach.
Do Probiotics Help?
The evidence for probiotics in adults with food poisoning is mixed. In children, studies have shown probiotics can reduce the duration of acute diarrhea by roughly 14 to 26 percent. In adults, results are less consistent. Some trials have shown a modest benefit, while others found no meaningful difference. The most commonly studied strains include various Lactobacillus and Bifidobacterium species, but no single strain has emerged as a clear winner for adult food poisoning.
If you want to try probiotics, they’re unlikely to cause harm. But they’re not a replacement for rehydration and gradual refeeding, which are the two things that matter most. A probiotic-rich food like plain yogurt might seem like a natural choice, but remember the temporary dairy sensitivity mentioned above. If you tolerate yogurt without worsening symptoms (fermented dairy contains less lactose than milk), it’s reasonable to include it after the first day or two.
A Practical Timeline
Everyone recovers at a different pace, but here’s a rough framework. In the first 6 to 12 hours, focus entirely on fluids: water, broth, oral rehydration drinks. Once vomiting stops or slows significantly, try a few bites of plain crackers, toast, or white rice. Over the next 24 to 48 hours, gradually add more variety: bananas, applesauce, scrambled eggs, plain chicken, cooked vegetables. By day three or four, most people can return to a mostly normal diet, though it’s smart to keep meals lighter than usual and continue avoiding dairy, fried foods, and alcohol for a few more days.
If you can’t keep any fluids down for more than 12 hours, notice blood in your vomit or stool, develop a high fever, or feel confused or extremely lightheaded, those are signs the illness has moved beyond what home care can handle.
