Heartburn, acid indigestion, or pareses are also known as acid reflux.
This occurs as some of the acidic content of the stomach goes back up to the oesophagus.
The stomach produces hydrochloric acid, a strong acid that helps break down food and prevents bacterial pathogens.
The stomach lining is specially designed to shield it from the strong acid, but it does not shield the oesophagus.
So, it is important to maintain an optimum acid level in the stomach, particularly in cases where people are faced with a constant acid reflux problem.
Moving forward, several preclinical, as well as clinically performed research studies, have shown that certain foods can aggravate GERD symptoms by triggering different mechanisms.
