How Pure is Distilled Water? The Instant Guide to How Pure and Safe This Popular Water Actually Is Author: Len McGrane, By the time you finish reading this you will have the answer to that question -- How pure is distilled water. About 40 or 50 years ago there was only one answer and every one knew it. Distilled water was said to be VERY pure. In fact so pure it was used to top up car batteries and operate the early steam irons. I remember my parents using it for both purposes when I was a kid. That was also the time when doctors and health specialists added glasses of pure distilled water to their recommended diets. Teachers demonstrated its purity in college labs to inquiring students (myself included) who watched water boil, turn to steam, condense in coils of glass tube and drip into a beaker at the other end of the class experiment. But how pure is distilled water? Does that early enthusiasm for distilled water and its correlation to good health still stack up? Well the answer is both Yes and No. How pure is distilled water? Very pure! When you boil water you will kill viruses, bacteria, cysts and organics. When you take it to stage two and vaporize it, you will leave all these things behind, plus any trace minerals like calcium, magnesium and potassium, heavy metals, radionuclides and solid particles. And what condenses back into liquid water in stage three has virtually everything stripped away leaving only H2O. Well, not quite. There are some volatile organic compounds that have a lower boiling point than normal water. So these liquids turn into gas before the water in a distiller does, and can move across the apparatus and mingle again with the water after it condenses. There are ways to filter them out, and if you do that you are left with virtually pure H2O. This is possibly the closest you will ever get to pristine, pure water. How pure is distilled water? It's as pure as you can make water. It's virtually isolated H20. But a question immediately arises -- if it's pure is it also healthy? The answer is, No. We need those vital trace minerals that got left behind on the wrong side of the glass coil. All of us have been taught our teeth and bones need calcium. Well our bodies depend on calcium and the other trace minerals for many functions, and without them we can't live. These minerals are found naturally deep under the earth where they are dissolved by the water down there and, as that water slowly rises to the surface, they are carried to the roots of plants and into our drinking water supplies. We ingest those minerals from food and water. This is a magnificent, natural cycle and while in theory we could use demineralized distilled water and get our mineral intake from plants, we're better drinking water that has these minerals naturally because that's how we were designed and built. And because distilled water has an acid pH value which means as soon as we drink some, our bodies pass electrolytes and minerals from tissues and organs to the water in a struggle to balance the pH and make it neutral. Distilled water sucks the goodness out of us. So distilled water is pure, but because it removes essential healthy minerals it is not completely healthy. This is the current scientific conclusion which has replaced the old science of 50 years ago, and tempers the fad of distilled water that blossomed in health circles in the latter part of the 1900s. Today, how pure is distilled water gets a more realistic answer -- it is pure but not healthy. It's great for labs where researchers must have pure water, but keep it out of your kitchen.
