When your stomach feels out of sorts, your digestive system is often seeking a break from heavy lifting. The key is to consume foods that are easy to digest, low in fat and fiber, and unlikely to irritate the stomach lining. Starting with a few easy-to-tolerate foods and focusing on hydration is the best approach.
The BRAT Diet: A Time-Tested Foundation
For decades, healthcare professionals have recommended the BRAT diet for its gentle, soothing qualities. The acronym stands for Bananas, Rice, Applesauce, and Toast. These foods are known for being bland, low in fiber, and starchy, which can help bind stools and calm an irritated digestive tract.
- Bananas: Rich in potassium, bananas help replenish electrolytes lost through vomiting or diarrhea. They are also easy to digest and can increase mucus production in the stomach, which protects the lining from irritation.
 - Rice: Plain white rice is a low-fiber, refined carbohydrate that is gentle on the stomach and can help firm up stools. Brown rice, being higher in fiber, can be harder to digest and should be avoided during a stomach upset.
 - Applesauce: This semi-solid food is easy on the stomach and contains pectin, a soluble fiber that can aid in digestion and help with diarrhea.
 - Toast: Simple white toast, made from white flour, is another low-fiber option. It can help neutralize excess stomach acid and is unlikely to cause further irritation.
 
While effective for short-term relief, the BRAT diet is restrictive and lacks many essential nutrients. It's meant as a temporary solution, typically for 1-3 days, before gradually reintroducing a more varied diet.
Expanding Your Bland Diet
Once you can tolerate the basics of the BRAT diet, you can begin to introduce other bland foods to help restore your strength and nutrients. This transition should be slow and mindful, paying close attention to how your body reacts.
- Saltine Crackers: These are dry, salty, and bland, and can help absorb excess stomach acid.
 - Oatmeal: Simple, cooked cereals like oatmeal are a good source of calories and can help soothe the digestive system.
 - Broth-Based Soups: Clear chicken or vegetable broth is an excellent way to provide hydration, salt, and some nutrients without stressing the gut.
 - Eggs: Plain scrambled or boiled eggs are a low-FODMAP, lean protein source that is easy to digest for many people.
 - Boiled or Baked Potatoes: These simple starches are a great source of energy and are gentle on the stomach.
 - Lean, Cooked Chicken or Turkey: Unseasoned, skinless chicken can provide necessary protein for recovery.
 
The Crucial Role of Hydration
Dehydration is a major concern with stomach upset, especially if it involves vomiting or diarrhea. Sipping fluids frequently throughout the day is better than drinking a lot at once, which can worsen nausea.
- Water: The most basic and important fluid. Always keep a glass or bottle nearby.
 - Herbal Teas: Ginger tea is particularly effective for nausea, while chamomile can have a soothing, calming effect.
 - Electrolyte Drinks: Commercial oral rehydration solutions (like Pedialyte) or sports drinks can help replenish lost electrolytes like sodium and potassium. Watch for high sugar content, which can sometimes worsen symptoms.
 - Clear Juices: Diluted apple or grape juice (avoiding citrus) can provide some hydration and energy.
 - Coconut Water: Another good source of electrolytes.
 
The Role of Probiotics
Probiotics are beneficial bacteria found in certain foods that can help restore a healthy gut microbiome, which is often disturbed during a stomach bug. Low-fat, plain yogurt with live and active cultures or other fermented foods like kefir can be helpful additions to your recovery diet. However, avoid sugary or flavored dairy, as these can exacerbate symptoms.
Food to Avoid When Your Stomach is Upset
Just as important as knowing what to eat is knowing what to avoid. These foods can irritate your stomach lining, increase acid production, and worsen symptoms.
- Fried and Fatty Foods: Slow down digestion and can cause bloating, diarrhea, and irritation.
 - Spicy Foods: Can trigger acid reflux and further inflame the digestive tract.
 - Acidic Foods: Citrus fruits (oranges, lemons) and tomatoes can increase stomach acid.
 - Caffeine and Alcohol: Both can irritate the stomach lining and should be avoided.
 - Excessive Fiber: While normally healthy, high-fiber raw vegetables and whole grains are harder to digest and can worsen diarrhea.
 - Full-Fat Dairy: Milk, cheese, and ice cream are high in fat and can be difficult to process.

Conclusion: Listen to Your Body
Navigating what is the best thing to eat when your stomach is upset is about prioritizing gentleness and hydration. Start with the basics of the BRAT diet and clear fluids, and gradually introduce a wider variety of bland foods as your symptoms improve. The goal is to support your digestive system's recovery without overwhelming it. Remember that recovery is a process, and eating small, frequent meals can help prevent further strain. For persistent or severe symptoms like fever, severe pain, or bloody stools, consult a healthcare provider promptly. Read more about abdominal pain on the Cleveland Clinic website.
