Purified Water and its Dangers

 By Bob McCauley, ND

Water cures, but purified water destroys anyone who consumes it.  Purified water is produced by distillation or reverse osmosis and should not be consumed for three reasons.  It acidifies the body, leaches alkaline material from the body, including minerals, and because of the large size and shape of its water molecule clusters it does not hydrate the body well.  In fact, long-term use can leave us dehydrated.  Purified water has had all the minerals removed from it, which is a substance that cannot be found in nature.  Because of its extreme purity, purified water absorbs carbon dioxide from the air, which makes it acidic and even more aggressive at dissolving the alkaline substances it comes in contact with.  It usually contains little or no dissolved oxygen and therefore is considered dead water.  Purified water enters the body pure, but does not come out pure.  It leaches vital minerals from the body, turning it more acidic.  Even purified water that has been ionized should be avoided.  Even though ionization does increase purified water’s hydration properties, the trade off is not worth it because it will steal minerals from the body.

Dr. Masaru Emoto, a Japanese researcher, first introduced the concept of micro-cluster water molecule clusters.  Using Magnetic Resonance Analysis, he demonstrated that water which had been distilled, polluted or passed through the body after consumption had lost its structure or inner order.  Destruction of this natural crystalline structure leaves purified water useless to the body.  It has been changed beyond its natural structure the same way cooking foods changes their natural chemical structure.  Purified water proponents insist that rain water is the same as purified water because rain is condensed from clouds which are accumulated air moisture.  Rain water, however, has a crystalline structure, thus it is completely different from purified water which has no structure.  Re-mineralizing purified water will allow it to regain its crystalline structure at which point it can now be consumed.

The water found in plants is quite similar to distilled water in its purity.  However, when we consume a plant such as a carrot, we do not only consume the water, but the whole plant as well, thus the water is buffered by the alkaline nature of minerals and enzymes of the plant.  But to extract that water and consume it without neutralizing its purity and acidic nature, our body becomes the buffering agent and alkaline minerals are leached from it.

The list of purified water proponents who are raw foodists and other naturalists is long.  Dr. Norman Walker, for instance, was a strong proponent of purified water, as was Paul Bragg.[1] I am one of the few naturalists who opposes the consumption of purified water, but I am not entirely alone.

“The longer one drinks purified water, the more likely the development of mineral deficiencies and an acid state.  Disease and early death is more likely to be seen with the long term drinking of purified water.” [2] Since it has been transformed into an unadulterated chemical substance (H2O), purified water naturally seeks to balance or mollify its extremely pure, acid condition with an alkaline buffer.  Removing minerals from water makes it hungry for anything that is not like itself.  All things in nature strive to balance themselves.  What is immediately available to purified water when it is consumed are the alkaline minerals and other alkaline material of the body, thus they are absorbed by the pure water and carried away with it as it leaves the body.  It is the extreme characteristics of purified water that encourages this leaching of minerals.  One person’s black hair completely turned gray after only two weeks on a distilled-water fast because all the copper, which is used to form hair pigment, was leached from his body.  While purified water can remove toxins, it will also take with it vital minerals and other elements important to the body, which promotes osteoporosis, osteoarthritis and a host of other diseases.

Many will argue that taking mineral supplements will compensate for the theft of minerals due to purified water.  If you have sea salt, algae, sea vegetables and a large variety of other raw foods in your diet, there may be a chance that this would occur.  Trying to replace them with mineral supplements is impossible, regardless of whether they are angstrom-size or chelated for better absorption.

“There is a correlation between purified water and how it steals calcium from the body.  [As this happens] the body begins to cannibalize itself to meet the calcium requirements of the body.  Chronic digestive problems such as gas and diarrhea are common among purified water drinkers. As the consumption of soft water (distilled water is extremely soft) increases, the incidence of cardiovascular disease also increases. Cells, tissues and organs do not like to be dipped in acid and will do anything to buffer this acidity including the removal of minerals from the skeleton and the manufacture of bicarbonate in the blood.” [3]

Paavo Airola[4] also warned about the dangers of purified water.  Reverse osmosis remains the water of choice in most health food stores.  The process of reverse osmosis and distillation denatures and adulterates water beyond its natural state.  Purified water is dead and therefore void of vibration or ORP.[5]  We should strive to consume substances that have a negative charge or ORP such as Ionized Water, raw foods and algae.

“The longer one drinks distilled water, the more likely the development of mineral deficiencies and an acid state. I have done well over 3000 mineral evaluations using a combination of blood, urine and hair tests in my practice. Almost without exception, people who consume distilled water exclusively, eventually develop multiple mineral deficiencies.” [6]

The size and shape of purified-water molecule clusters is substantially different from conventional water, rain water or Ionized WaterWater has been shown to have a “memory”; even if it is substantially changed it will eventually revert to its original shape and vibration frequency.  However, if water is completely stripped of its minerals and oxygen, it is dead and this “memory” is lost.

Proponents of purified water state that the minerals in conventional water collect in our veins over time and become like cement, which is an absurd and entirely unsupported notion, scientifically or otherwise.  Autopsies of elderly people who have consumed water with a high mineral content all their lives have shown no indication of cementing in their veins whatsoever.

“Those who supplement their distilled water intake with trace minerals are not as deficient but still not as adequately nourished in minerals as their non-distilled water drinking counterparts even after several years of mineral supplementation.”[7]

Proponents of purified water also claim that the amount of minerals in conventional water are small, about what is found in a slice of orange per eight ounce glass of water.  However, this misses the point entirely.  The minerals found in conventional water provide better hydration and a crucial buffer that prevents minerals from being leached from the body.  It also does not acidify the body.

Purified Water can be used to detoxify the body on a short-term basis, one or two days at the very most.  It can leach toxins out of the body quite efficiently, but does so in a completely different way than Ionized Water, which is safer and more effective in the long run.

“Fasting using distilled water can be dangerous because of the rapid loss of electrolytes (sodium, potassium, chloride) and trace minerals like magnesium, deficiencies of which can cause heart beat irregularities and high blood pressure. Cooking foods in distilled water pulls the minerals out of them and lowers their nutrient value.” [8]

The hydration properties of purified water are extremely poor.  People who drink as much as one gallon of distilled water per day for years can find themselves dehydrated because purified water does not properly hydrate the body and its cells.  The structure of a purified-water molecule cluster is five-sided or pentagonal, and the angle at which the molecules come together, called the bond angle, is extremely high and the water molecule is quite large.  The larger the bond angle, the less hydrating the water is.  These large water molecules do not penetrate body tissue or its cells efficiently; therefore, purified water does not hydrate the body well.

Ionized Water and purified water are exactly the opposite from each other in every way.  Purified water is acid; Ionized Water is alkaline.  Purified water leaves the body dehydrated; Ionized Water is extremely hydrating.  Purified water leaches minerals from the body; Ionized Water provides minerals to the body.[9] Purified water does not provide the body with oxygen; Ionized Water does.  Purified water does not scavenge for free radicals; Ionized Water does.  Purified water encourages oxidation of the body; Ionized Water reduces oxidation.

FDA labeling regulations require that only water purified by reverse osmosis or distillation can be labeled Drinking Water.  Leave it to regulators to confuse the public on this issue, but it is crucial.  Don’t consume anything labeled Purified Water or Drinking Water.

[5]  ORP stands for Oxidation-Reduction Potential or Redox Potential). It is a measurement of the ability of one substance to oxidize another.  Potential refers to electrical potential, which is measured in millivolts.  Oxidation means to combine with oxygen.  Rust is an example of slow oxidation, fire an example of quick oxidation.  Oxidation involves an exchange of electrons between two atoms. An atom that loses an electron in the process has been oxidized.  The one that gains an electron has been reduced.  This is why Ionized Water is sometimes called reduced water.  In picking up that extra electron, it loses the electrical energy that makes it hungry for more electrons. Chemicals such as bromine, chlorine, and ozone are all oxidizers.  They have the ability to oxidize or steal electrons from other substances.  An ORP meter measures the millivolts of any liquid to determine the ORP value.

The more hydrogen ions that are present, the more acid the water becomes since pH (potential for hydrogen) is a measurement of the presence or absence of hydrogen ions. Body pH is a measurement of electrical resistance between negative and positive ions in the human body.  If the body possesses an abundance of positive hydrogen ions, we are acidic.  If the body possesses an abundance of negative hydroxyl ions, we are alkaline.

    We have an RO water filter system.
    Our water is city water.
    If RO is bad, what filter system do you reccomend that filters out the “bad” but leaves the “good”?

  2. Howard says:

    and…forgot to add, we use a water softener for the entire house so any filter system would be filtering soft water.

    Unquestionably imagine that which you said. Your favourite
    reason appeared to be at the web the easiest thing to have in mind of.

    I say to you, I definitely get annoyed at the same time as people think about issues that they just do not realize about.
    You controlled to hit the nail upon the top and outlined out the
    whole thing without having side-effects , other folks could take a signal.
    Will likely be again to get more. Thank you
