Our body’s PH controls the speed of our body’s biochemical reactions. Our body’s live and die at the cellular level. The cells in our body must maintain alkalinity, in order to function and stay alive. Our first line of defense against disease is a proper PH balance. Disease can only grow in an acidic body, which makes a condition favorable for the growth of bacteria, yeast, fungus, mold, viruses, and many other unwanted organisms.
