Based on my research, acid reflux is from a lack of acid in the body, not a build-up. It's counter-intuitive until you understand it. It's usually caused by eating too many acidic foods (i.e. white sugar, coffee, processed carbs, etc). which require stomache acids to break them down (the old saying that 'like dissolves like' applies here).
You need to add specific fruits/veggies to your diet that will help to add healthy acids to your body, which (and this is the counter-intuitive part) will turn your body back to a more alkaline (i.e. basic) state. Certain fruits/veggies are acidic, but when processed by the body, chemically turn alkaline.
*(make sure you drink water/brush teeth after eating these foods so you don't hurt your teeth enamel. They are highly acidic).*
