Demineralized water FAQ Frequently Asked Questions
What is demineralised water?
Demineralised water is water completely free (or almost) of dissolved minerals as a result of one of the following processes:
The amount of dissolved solids in water that has followed one of these processes could be as low as 1 mg/l and is in any case always less than 10 mg/l. The electrical conductivity is generally less than 2 mS/m and may be even lower (< 0,1 mS/cm).
Due to the water shortages in some regions of the world (Middle East, for example), seawater is used to produce drinking water by a desalination process in more than 7.500 desalination plants worldwide. This desalinated or demineralised water is in most of the cases enriched with some minerals before it is packaged in bottles, tetra bricks or even plastic bags to be consumed by people. The aim of this mineral enrichment is to make the water fully appropriate for consumption.
There are three evident reasons:
There are a number of studies, conducted by health professionals in different parts of the world, which support the three statements above. Here is an example of some of these studies and the resulting conclusions:
…and a very long etcetera of properly conducted experiments, which demonstrate what the World Health Organization is also claiming:
The WHO published in its latest report available (2004), that it has been adequately demonstrated that consuming water of low mineral content has a negative effect on homeostasis mechanisms, compromising the mineral and water metabolism in the body.
As we explained before in this page, distilled water is very low in mineral content. When cooking any vegetable rich in minerals in demineralised water, a negative osmotic pressure appears on the vegetable which makes it loose all its minerals in behalf of the water. That is, the vegetable would loose all its minerals, which would pass on to the water, which is then thrown away into the sink. As a result, we would be eating vegetables laking on essential minerals.
In brief: cooking foods in distilled water lowers their nutrient value.
Here are some of the proven risks of demineralized water or water low in minerals:
In spite of all this clear evidence set out above, there is still a controversy going on about the so-called benefits of distilled water, some people defending surprising “theories” like the following:
However, as far as Lenntech could know, none of these statements have been supported by any actual experiment, reason why they lack credibility.
There is no doubt that personal and cultural beliefs influence both our perceptions and our interpretations of reality. It is because of this that scientifics developed some standard criteria and procedures, which aim to minimize those influences when developing a theory. It's the "scientific method", which follows 4 steps:
1. Observation and description of a happening.
2. Formulation of an hypothesis (tentative description) to explain the happening and which is consistent with the observation.
3. Use of the hypothesis to predict other happenings of the same kind.
4. Proper performance of experimental tests of the predictions by several independent experimenters.
5. Repeat steps 3 and 4 until there are no discordances between theory, experiment and observation.
The statements of Joe Letorney Jr., Gary R. Rose and Colin Ingram are missing the last two steps of the scientific method.
Any assumption which hasn't followed these steps, cannot be considered as a valid theory.
