My wife always drinks distilled water and rarely juice, I on the other hand, drink juice and rarely ever drink plain water. We lack organic minerals, so making juce with the distilled water is ideal to me. Even adding 1 drop of pure oregano oil to the daily supply of distilled water is GREAT, but most people will tell you they drink it straight and that is fine. My 4 year old drinks fruit juice only and water only under protest and he is my best teacher! His juice many times is 1/2 distilled water!
Plain distilled water does ZERO HARM to animals and plants. Well water kills plants and humans as well, history and self-experimentation proves this to be facts to me.
