Facts about Distilled WaterFrom reading about all the pollutants that can contaminate your water, is it safe to conclude the the purest water, water that is nothing but water, is the best drinking water? But not all the substances in water are necessarily harmful to your health. In fact, some substances in water are healthgiving.
Drinking Distilled water?
Distilled water is water that has essentially all of the dissolved substances within it removed. It is removed by evaporating it and condensing it back to liquid form. Since 99 percent of all dissolved matter in water is minerals, distilled water is essentially water that has had all of it's minerals removed.
The information presented here also applies to water that has been demineralized by other methods and is known as purified, demineralized or de-ionized water.
Pros and Cons
As with fluoridation, there are lots of pro and con arguments about distilled water. The argument in favor of drinking, it says that the minerals present in water clog up bodily functions. This theory is partly based on the notion that since calcium (the primary mineral in water) helps to form bones and to harden things in general, it must harden other things in your body as well.
Literally dozens of books written by well-meaning doctors, nutritionists, and practitioners of holistic medicine claim that essentially all disease is caused by minerals in water-so that by drinking distilled water you will be invigorated, your arthritis or hardened arteries will disappear and so on.
These well-meaning authors actually know very little about water chemistry, and the "evidence" they present is heavily biased and without credibility.
An argument against drinking distilled water is that you lose a primary source of necessary minerals in your diet, and further, that because the water has lost its own minerals, it attracts and grabs minerals within your body, causing a mineral deficit. This argument has some plausibility. Even though we do get most of our minerals from fruits and vegetables, and mineral shortages in our bodies are unlikely if a normal diet of mixed foods are eaten, water that has a high mineral content definitely contributes to good health.
Many people don't like the taste of distilled water, which is often described as tasting "flat." Water bottling companies know that demineralized water doesn't taste as good, and that's why they add minerals to their bottled water after it has been demineralized during the purification process.
Storing Distilled Water
Care must be taken in the way distilled water is stored, because of it's aggressiveness." Water in it's natural state always contains mineral. Demineralized water is in an unnatural condition, and it tries to correct this by combining with any other substances it can. Any substances available to combine with distilled water can only come from things it comes in contact with, such as containers and air. Since containers are usually closed, and since air is relatively free of harmful pollutants, containers are the problem.
No container is completely inert (chemically inactive). because of it's "aggressiveness," distilled water will leach out (combine with) some of whatever the container is made of. Glass is the most inert material for containers, and therefore the safest. Though distilled water is routinely sold in plastic bottles, there is a tendency for the plastic to enter the water over a period of time.
I recommend that distilled water, whether purchased in bulk or produced at home by your own distiller, be stored in glass bottles as soon as possible. And if you are drinking distilled water regularly, make sure that your diet contains a good assortment of mineral rich fruits and vegetables.
