| Sorry about that. Didn't intend to be disagreeable, but I'm not drinking
the kool-aid on this one, water can not be too clean to drink, the article is a drama piece based on a false "fact". Also must apologize for saying ultrapure is "biologically" equivalent when I meant dietarily equivalent for most people. There can easily be germs or trace minerals even in commercial distilled water which could interfere with biological cultures causing difficulties which would not be a problem when using ultrapure. Here's a good test sheet for the kind of ultrapure used to rate other waters for trace elements: http://www.emdmillipore.com/US/en/product/Q-POD-Element,MM_N... The commonly consumed solvent that I want to be careful
about is alcohol. Water, OTOH is the solvent of life.
A healthy solvent no doubt. Solvent strength and solubility calculations show complete
dependence on relative concentrations of solutes, let's
look at the math. Take for example magnesium, in blood this is often
the lowest in concentration of the routine electrolytes tested, and there's no doubt the right amount of magnesium is good for the health. "Drinking" water is Ozarka's grade having highest magnesium at about 3.9mg/L max. People love this stuff.
Me too when I can't get distilled.
But you're SOL depending on this popular typical drinking water for magnesium completely, you need another source. One liter of their distilled water can have 0.1mg max of Mg.
(usually way less, but no need to test it any more sensitively since it's not ultrapure or anything exotic) Ultrapure at 0.0000004mg typical per liter is what we're talking about for reference. The cleaner the water the better the reference. Great discrepancy here but the take away is that all these figures are inadequate sources of magnesium compared to what you need. In typical patients urine is draining about 6 - 10 mEq/day, or 73 to 122mg/day, for an average of 97mg/day. Now suppose you drink in 2 liters and it ends up flowing out at 97mg/day: Ozarka Drinking water has some (palatable) magnesium in it, so you lose less, at 89mg With their distilled you lose more, at least 97mg with ultrapure you would lose the most, almost the whole 97mg The RDA for magnesium is 310 to 420mg/day of which 350mg is recommended as maximum from supplements.
The difference between typical drinking water magnesium content and deionized (distilled or ultrapure)
is about 8mg/day when you are supposed to be consuming at least 38x that difference per day.
If you're not getting that much magnesium your nutrition may not be the best, and if you are getting the RDA then the 8mg delta is not much more than rounding error.
The 8mg is also a low fraction of the normal 49mg loss range from 73 to 122mg/day, and a small fraction of the full RDA. I'm not making this up they way they are getting their facts in the article. Distilled is a very good solvent, especially for minerals, put it in your windshield washer tank
and you can see the difference. Delicious too, try some blind testing. No affiliation wih Ozarka on my part either. Not a full 1000words, but hope this helps. |
