Our stomach has a lining made from epithelial cells. These cells produce and secrete hydrochloric acid (HCl). HCl is extremely acidic. And the stomach needs this acidity, to help digest foods. The environment inside the stomach has a pH of approximately 1.5, which as we said, is very acidic.

When one eats acidic foods in excess, this provides additional acid to the stomach. Increasing the acid content means that when some of the contents of the stomach reflux (or flow backwards) up into the esophagus, the symptoms of acid reflux are worse. Eating acidic foods can worsen heartburn and throat pain associated with acid reflux.
