that's just way to general and way too much depending on the objective thing called taste. Next to chocolate/coffee/... I also really like the taste of vegetables like carrots, broccoli, fennel, pumpkins, ... I really doubt they would fall under the category of stuff which is likely to increase reflux.

The only food I've found gives me heartburn is black olives.

Conveniently, I don't really like them.

By the way, I forgot tomato from my ban list :)
