Why Does Apple Cider Vinegar Cure Heartburn?
Though vinegar is acidic, apple cider vinegar is alkaline-forming. It is an alkaline-ash food, which means if burned it would leave ash with an alkaline Ph. Though food is not “burned” within the body, alkaline-ash foods are generally alkaline forming. The acid in apple cider vinegar is acetic acid, a weak acid. When it meets stomach acid (which is hydrochloric acid, a strong acid), the overall acidity of the stomach is reduced but not rendered too alkaline to digest most foods. And since the apple cider vinegar is alkaline forming, it has an overall alkalizing effect on the body, which most people need due to our modern, acid forming diets.
