When your stomach is upset, the best things to eat are bland, low-fat foods that require minimal digestion: plain rice, toast, bananas, applesauce, crackers, and clear broth. But what you eat matters less than when and how you eat it. Rushing back to solid food too quickly can make things worse, and restricting yourself to only a handful of foods for too long can slow your recovery.
Start With Liquids, Not Food
If you’ve been vomiting, don’t eat anything right away. Give your stomach a few hours of rest before even reaching for water. When you’re ready, start with small sips of water every 15 minutes, or suck on ice chips if even sips feel like too much.
Once you can keep water down for an hour or so, move to other clear liquids: clear broth, watered-down electrolyte drinks, ice pops, or gelatin. These give your body fluid and a small amount of energy without asking your digestive system to do much work. Dehydration is the real short-term danger with vomiting and diarrhea, so replacing fluids comes before replacing food.
The Best Bland Foods to Reach For
After you’ve tolerated liquids for a few hours and your appetite starts to return, ease into bland solids. The classic BRAT diet (bananas, rice, applesauce, toast) is a fine starting point, but you don’t need to limit yourself to just those four foods. Harvard Health notes there are no studies showing BRAT is superior to a broader bland diet. It’s reasonable to follow it for a day or two, but a less restrictive approach may actually help you recover faster by providing more nutrients.
Good options beyond BRAT include:
- Plain oatmeal cooked with water, not milk
- Saltine crackers or dry biscuits
- Clear soup or broth (chicken or vegetable)
- Boiled or baked potatoes without butter or toppings
- Plain noodles or pasta
- Steamed white rice
The common thread is low fat, low fiber, and minimal seasoning. These foods move through your stomach without triggering more acid, cramping, or nausea. Eat small amounts slowly, and eat more frequently rather than sitting down to a full meal.
Why Ginger Actually Helps
Ginger has real evidence behind it for nausea relief. Clinical trials have used doses ranging from about 1 to 2 grams per day (roughly a half-inch piece of fresh ginger), though studies vary widely. The simplest way to use it: steep sliced fresh ginger in hot water for five to ten minutes to make a tea, or sip flat ginger ale. Ginger chews and ginger candies also work. If fresh ginger tastes too intense on a sensitive stomach, start with a diluted tea and see how you feel.
Temporary Lactose Sensitivity Is Common
After a bout of stomach flu or food poisoning, your gut lining takes a hit. One practical consequence is that many people temporarily lose the ability to digest lactose well, even if dairy doesn’t normally bother them. This happens because the enzymes that break down milk sugar sit on the surface of intestinal cells, and those cells need time to regenerate.
Researchers at Monash University recommend switching to lactose-free milk, yogurt, and cheese during recovery. This is especially worth trying if you notice bloating, gas, or worsening diarrhea after eating dairy. Most people can return to regular dairy within a week or two as the gut heals.
Foods That Will Make Things Worse
Some foods actively irritate an already upset stomach. Avoid these until you’re feeling consistently better:
- Fatty and fried foods: Greasy meals slow digestion and increase acid production. Skip bacon, fried snacks, cream sauces, and rich desserts like ice cream or chocolate.
- Spicy foods: Capsaicin and other compounds in hot peppers can trigger more acid reflux and stomach irritation.
- Full-fat dairy: Whole milk, butter, regular cheese, and sour cream are harder to break down, especially with temporary lactose sensitivity.
- Caffeine: Coffee, energy drinks, and strong tea stimulate acid production and can speed up digestion in ways that worsen diarrhea.
- Alcohol: It irritates the stomach lining directly and dehydrates you further.
- Raw vegetables and high-fiber foods: Normally healthy, but they require more digestive effort than your stomach can handle right now.
How to Transition Back to Normal Eating
Most people can return to their regular diet within two to three days. The key is a gradual ramp-up rather than a sudden jump back to full meals. Once bland foods are sitting well, start adding in lean proteins like plain chicken breast or eggs. Then reintroduce cooked vegetables. Fatty foods, dairy, raw produce, and anything spicy should come last.
If you had significant diarrhea, Monash University’s research suggests that a low-FODMAP approach during recovery can help. FODMAPs are certain sugars found in foods like apples, onions, garlic, wheat, and beans that pull extra water into the intestines and feed gut bacteria that produce gas. Temporarily cutting back on high-FODMAP foods while focusing on options like rice, potatoes, plain meats, and lactose-free dairy can reduce bloating and loose stools while your gut recovers. This is particularly useful during the window between the acute 24 to 48 hours and full recovery.
What About Probiotics?
Probiotic supplements and fermented foods are often recommended for gut recovery, but the evidence is mixed. A systematic review of clinical trials found no statistically significant benefit of probiotics for reducing diarrhea duration. That doesn’t mean they’re useless for everyone, but they aren’t the reliable fix they’re often marketed as. If you want to try them, plain yogurt (lactose-free if needed) or a basic supplement is unlikely to cause harm. Just don’t count on them as your primary recovery strategy.
Signs Your Stomach Needs More Than Food
Most upset stomachs resolve on their own within a day or two. But certain symptoms signal something more serious. Sudden, severe abdominal pain that doesn’t ease within 30 minutes warrants emergency care. The same goes for continuous vomiting that prevents you from keeping any liquids down, blood in your vomit or stool, high fever, or signs of severe dehydration like dizziness, dark urine, or no urination for several hours. These can point to conditions that require treatment beyond dietary changes.
