acidic food definition
Foods that produce an alkaline ash are called alkaline forming food whereas those producing acid ash are called acid-forming foods. The body needs both types of foods. However alkaline forming food should predominate over acid forming ones.H (potential of hydrogen) is a measure of the acidity or alkalinity of a solution. The pH is measured on a scale of 0 to 14--the lower the pH the more acidic the solution, the higher the pH the more alkaline (or base) the solution.
