I have another question about distilled water.  
 
The alternative medical practitioners I know tell me that according to  
muscle testing, and also negative results with patients who used distilled  
water, 
distilled water drinking over the long haul is harmful because it leaches  
nutrients from the body.  I know that my nanofilter water filter produces  pure 
water at 16 parts per million dissolved solids.  I have had to modify  it to 
produce a quality of water similar to drinking water, around 100 parts per  
million.  The trouble is that the water is so pure without modification of  the 
filter that it leaches copper out of my pipes and deposits it in the shower,  
bathtubs and toilets, turning them turquoise blue.  Some patients who have  
used 
distilled water for long periods have come down with serious health  problems 
the alternative practitioners say are due to the lack of nutrients  removed 
by the distilled water.  
 
I know that there are very competent and well-meaning alternative  
practitioners who think that distilled water is the best way to go.  I have  a 
Water-Wise unit myself.  I know this is sold by (if I remember correctly,  
David 
Williams, M.D., who is very big on alternative health, and very  competent).  I 
have 
attempted to contact David Williams to ask him about  the dangers of nutrient 
depletion with distilled water, but those answering the  phone don't know 
much, and the question was never forwarded, or never answered  by Dr. Williams. 
 
 
Because of my experience in muscle testing, and those practitioners who do  
it reliably and tell me that distilled water is harmful over the long haul, I  
would not use it much, except to make CS, or as a back-up in case our well got 
 contaminated.  
 
Ultimately, I think that there is only one correct answer to whether or not  
distilled water is harmful over the long haul.
