Acid reflux. Food for thought. Why is there acid reflux. It is always due to the foods we eat. Change what you eat and the reflux will stop. Acid is needed for food breakdown and killing bacteria and proper digestion. Without it there is not good health. So goal should always be to address root cause and the treatment should be for acute issues till we can figure what to change.
