The "pH Factor"
... Why Should I Be Concerned About My pH Levels? Since most of the body is water-based (making up 50-60% of our total body weight), the pH level has profound effects on all body chemistry, health and disease. An imbalanced pH describes the pH level of the body when it becomes too acidic or too alkaline ...
