What the proponents of this myth want you to believe is that because distilled water is so pure, drinking it will leach minerals from your body, thereby robbing you of good health and nutrition. There is no basis of fact to document this claim.
The national best-selling health and diet book, : “Fit for Life II: Living Health” by Harvey & Marilyn Diamond, answers this question. The following is an excerpt:
“Distilled water has an inherent quality. Acting almost like a magnet, it picks up rejected, discarded, and unusable minerals and, assisted by the blood and the lymph, carries them to the lungs and kidneys for elimination from the body. The statement that distilled water leaches minerals from the body has no basis in fact. It doesn’t leach out minerals that have become part of the cell structure. It can’t and won’t. It collects only minerals that have already been rejected or excreted by the cells…To suggest that distilled water takes up minerals from foods so that the body derives no benefit from them is absurd.”
