30 Foods That Cause Acid Reflux
Spicy Foods

Spicy or hot foods don't help acid reflux. Some spices can irritate the stomach lining, like chili peppers. Many spicy foods contain capsaicin, which can produce a burning sensation on tissue, which only exacerbates acid reflux symptoms.
For some people, excessive amounts of pepper could be enough to trigger acid reflux and heartburn. To keep track of what triggers your symptoms, it may be best to keep a food journal.
