I am into a research what makes body healthy, the secret is just simple only maintain your body's pH level to 7.
the reason why we are prone to infection and diseases because if our body's pH level drops enzymes are
deactivated. Normal pH level is at 7, below becomes acidic once a person become acidic its vulnerable to all types
of illnesses.

I am not a medical practitioner or promoting a product i just want to share my own point of view.
