1. Spicy Foods
Foods loaded with chili peppers, hot sauces, or strong spices can irritate an already sensitive lining for some people. Even if spicy food doesn’t cause ulcers (a common myth debunked years ago), it may trigger burning sensations in those with active sores.
- Black pepper, cayenne, or chili-based dishes
- Curry-heavy meals
- Hot wings or spicy snacks
But that’s not all…
2. Acidic Foods and Drinks
Highly acidic items can increase stomach irritation and discomfort.
- Citrus fruits (oranges, lemons, grapefruits) and their juices
- Tomatoes and tomato-based products like sauce or salsa
- Vinegar-heavy dressings or pickled foods
Studies suggest these may bother some more than others, so test small amounts if curious.
3. Caffeinated Beverages
Coffee, tea, and energy drinks stimulate acid production in many people.
- Regular and even some decaf coffee
- Black tea or green tea in large amounts
- Soda with caffeine
The evidence is mixed – not everyone reacts the same – but reducing them often brings relief.

4. Alcohol
Alcohol irritates the stomach lining directly and can delay healing.
