well i am not an expert on this, just like the rest of you, but here is my take on things...
i don't think drinkiing DI water will cause you any health issues.
as most have stated on this topic before, it would appear the main factors as to why you wouldnt want to drink DI is...
1) you may not be used to it, so it may not sit well with your stomach
2) it is lacking in any minerals, which ofcourse your body needs...but if you eat food this shouldnt be a problem
3) it has nothing to give it the "water" taste that we are used to drinking, so it will not taste as good
4) it is more expensive than plain RO!!
i think you will only run into issues if you drink insane amounts of DI water and do not eat a proper diet to provide the minerals and elements that your body requires...but when will that happen?!?
anyhow, if you care to share your opinions or
constructive thoughts on this, please do
