A food infection, often mistakenly called food poisoning, is caused by ingesting food contaminated with bacteria, viruses, or parasites. The resulting inflammation and irritation in your stomach and intestines can cause symptoms like nausea, vomiting, and diarrhea. To help your body heal, it's essential to rest your digestive system and choose foods that won't aggravate your symptoms. This means temporarily excluding certain foods and focusing on a gentle, bland diet.
High-Fat and Fried Foods
Fat is harder for the body to digest than carbohydrates or protein, especially when your stomach is already inflamed. Consuming high-fat foods during a food infection can slow down gastric emptying, leading to increased feelings of bloating and nausea. Avoiding these items is crucial for a smoother recovery.
Examples of high-fat foods to avoid:
- Fried foods (e.g., french fries, fried chicken)
- Fast food, including pizza
- Fatty cuts of meat
- Processed cheeses and full-fat dairy
- Foods prepared with excessive butter or oil
Spicy and Acidic Foods
Spicy foods can irritate the stomach lining, while acidic foods can increase stomach acid production, both of which can exacerbate symptoms like nausea, heartburn, and abdominal discomfort during recovery. Keeping your diet as bland as possible is the safest approach.
Foods in this category to avoid:
- Chili peppers and hot sauces
- Curries and heavily seasoned foods
- Citrus fruits (oranges, lemons, grapefruits)
- Tomatoes and tomato-based products (e.g., sauces, ketchup)
- Pickles and other high-acid foods
High-Fiber Foods
While fiber is a key component of a healthy diet, it can be difficult for an inflamed gastrointestinal system to process. Temporarily limiting high-fiber foods can reduce bloating, cramping, and excessive bowel movements. It is wise to transition back to a high-fiber diet gradually as your stomach heals.
Foods to temporarily limit:
- Whole grain breads and cereals
- Brown rice and wild rice
- Raw vegetables, such as broccoli and leafy greens
- Legumes and beans
- Nuts and seeds
- Most raw fruits (especially with skin)
Dairy Products and Lactose Intolerance
After a gastrointestinal infection, it is common to experience a temporary decrease in lactase, the enzyme needed to digest lactose in dairy products. This can lead to temporary lactose intolerance, causing gas, bloating, and diarrhea. Avoiding most dairy can help prevent these complications during recovery.
Dairy to avoid:
- Milk and ice cream
- Soft cheeses
- Butter and cream-based products
It is important to note that some fermented dairy products, like yogurt with live cultures, may be tolerated better and can even help restore beneficial gut bacteria.
Sugary and Caffeinated Beverages
Sugary drinks can draw water into the intestines, potentially worsening diarrhea. Caffeine acts as a diuretic and can stimulate the colon, which can exacerbate symptoms and increase dehydration.
Drinks to stay away from:
- Coffee and caffeinated teas
- Energy drinks and sodas
- Highly sweetened fruit juices
- Alcohol
Foods and Drinks for a Gentle Recovery
When you feel ready to eat, the focus should be on gentle, easy-to-digest foods. Hydration with clear fluids is paramount, especially if you have been vomiting or experiencing diarrhea. Drinking small, frequent sips of fluid is often better tolerated than large amounts.
Hydrating and soothing options:
- Water and diluted fruit juices (like watered-down apple or grape juice)
- Clear broths or consommé
- Herbal teas, such as ginger or chamomile, which can help soothe the stomach
- Oral rehydration solutions to replenish lost electrolytes
Bland foods for reintroduction:
- The BRAT diet: Bananas, white rice, applesauce, and white toast
- Saltine crackers
- Plain boiled potatoes or sweet potatoes
- Plain oatmeal
- Skinless, baked chicken or turkey
What to Avoid vs. What to Eat: A Comparison

|---|---|---|
| Fats | Fried foods, fatty meats, butter, pizza | Plain baked chicken, broth, simple crackers | 
| Spices & Acids | Chili, curry, tomatoes, citrus fruit | Bananas, cooked carrots, plain rice | 
| Fiber | Whole grains, raw vegetables, beans, nuts | White rice, white toast, canned peaches (no skin) | 
| Dairy | Milk, ice cream, soft cheeses | Yogurt with live cultures (if tolerated), lactose-free options | 
| Beverages | Caffeine, alcohol, sugary juices, sodas | Water, oral rehydration solution, clear broth, herbal tea | 
Conclusion
Navigating your diet during a food infection is about giving your body the space and resources it needs to heal. By temporarily eliminating irritating foods like high-fat, spicy, and high-fiber items, you can minimize digestive distress and reduce symptoms. Rehydrating properly and gradually introducing bland, easy-to-digest foods are the cornerstones of a successful recovery. Always listen to your body, and if symptoms are severe or persistent, it's important to consult a healthcare professional for guidance.
