Most of us heard the terms "anti-oxidants" and "free radicals", but do you know what they mean? Free radicals are unstable oxygen atoms that cause oxidation in our bodies, which brings about the aging process. And increase in free radicals can be caused by such things as pollution and contaminated food and water. The most observed example is an apple after it has been sliced open. As the oxygen in the air comes into contact with the surface of the apple, it begins to turn brown. Another example is seen when metal is left out in the sun - it begins to rust. This rusting is oxidation, and that is what is happening on the inside of our bodies, but now, we have Kangen water.
