30 Foods That Cause Acid Reflux
Jam or Jelly

Jam and jelly taste great on a peanut butter sandwich, but it's pretty acidic. It has a highly acidic pH and is nothing but sugar. If you have to have jelly, try to eat an alkalizing fruit like bananas with it to bring down the acid levels.
For some, pure honey could be a better option than processed jams. If you want to eat jam, avoid acidic foods like blueberries, strawberries, and raspberries.
