Many health fanatics, however, are often surprised to hear me say that drinking purified water on a regular, daily basis is potentially dangerous.
Purified water is an active absorber and when it comes into contact with air, it absorbs carbon dioxide, making it acidic. The more purified water a person drinks, the higher the body acidity becomes. According to the U.S. Environmental Protection Agency, "Purified" water, being essentially mineral-free, is very aggressive, in that it tends to dissolve substances with which it is in contact. Notably, carbon dioxide from the air is rapidly absorbed, making the water acidic and even more aggressive. Many metals are dissolved by purified water.
