20+ Most and Least Acidic Juices

shirinMedically Reviewed by Shirin Buta · Written by Rizza Joyce Mira, MD · Updated on April 12, 2023

Many people with acid reflux or GERD follow a diet low in acidic foods and drinks to avoid triggering or worsening their symptoms. Heartburn, the primary symptom, is a burning sensation in the middle of the chest and is always unpleasant, sometimes debilitating.

Such diets can be tricky to design and difficult to maintain, as many common foods and drinks are acidic and acid-forming, meaning they're likely to bring on a heartburn attack.
