I'll start with a brief summary, then let you read and would like your
comments.

The gist of this posting is that Distilled Water (or RO water or pure water) is
said by some experts to be damaging to the body, used in long term. That
because pure water is so corrosive, so active in leeching out minerals and in
creating an acid environment that it prematurely ages and damages the body.

When I read this, I thought....probably that is nonsense. But, I got out my pH
tester I used for my fish tank and I decided to check and see if Pure Water was
acidic or alkaline. I tried first my tap water and it was mildly alkaline at
7.4 pH. Next I bought a gallon of distilled water and it tested acidic at a pH
of 6.2. Then I tested the gallon of Reverse Osmosis filtered water which I
usually buy (and refill myself) at WalMart. It also tested quite acidic at 6.2
pH. This got me thinking, "Is this guy onto something, here?" Here is the link
to an article by a Dr.Zoltan Rana,

Btw, I have nothing to sell to you nor anything to buy. I suggest us folks get
out our pH tester and test the "pure" water we are drinking. I tend to agree
now that our main drinking water source should be slightly alkaline and
definitely should not be acidic. Here are some quotes from the above link,

Early Death Comes From Drinking Distilled Water    
   
During nearly 19 years of clinical practice I have had the opportunity to
observe the health effects of drinking different types of water.
   
Distilled water is an active absorber and when it comes into contact with air,
it absorbs carbon dioxide, making it acidic. The more distilled water a person
drinks, the higher the body acidity becomes.
   
The most toxic commercial beverages that people consume (i.e. cola beverages
and other soft drinks) are made from distilled water. Studies have consistently
shown that heavy consumers of soft drinks (with or without sugar) spill huge
amounts of calcium, magnesium and other trace minerals into the urine.
The more mineral loss, the greater the risk for osteoporosis, osteoarthritis,
hypothyroidism, coronary artery disease, high blood pressure and a long list of
degenerative diseases generally associated with premature aging.

A growing number of health care practitioners and scientists from around the
world have been advocating the theory that aging and disease is the direct
result of the accumulation of acid waste products in the body.
   
There is a correlation between the consumption of soft water (distilled water
is extremely soft) and the incidence of cardiovascular disease. 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.
