Distilled water has been artificially processed to remove minerals and other constituents. In other words, the distillation process takes out every additional substance naturally found in water until all that is left is the H20 molecules. Originally, this water was manufactured for use in various industries and in science laboratories.
MYTH: Because our awareness has grown about the potential chemicals and toxins in our drinking water, a belief has developed that distilled water is the healthiest form of water because it does not contain any of these contaminants.
TRUTH: Distilled water has been demineralized, making it a very hard and aggressive kind of water that leaches minerals, metals and other materials from the body through a process called osmosis. In fact, it’s so aggressive, the World Health Organization reported that “its distribution through pipes and storage tanks would not be possible. The aggressive water attacks the water distribution piping and leaches metals and other materials from the pipes and associated plumbing materials.” If demineralized water is too aggressive for metal piping, it is scary to think what it would do to our internal organs.
In addition, those who are trying to avoid drinking acidic water should also avoid distilled water. In theory the PH balance of distilled water should be a neutral 7, but demineralized water eagerly absorbs carbon dioxide from the air. This turns it acidic with a PH balance ranging from 5.7 – 7.
If you are drinking demineralized water, talk to your Naturopathic Doctor about adding in trace minerals. Your ND will know what kind and in what dosage these minerals should be added.
