Aww that's rich ain't it? I wonder who told you that? In all seriousness though distilled water IMO is the only clean/pure water. What is water? It is a solvent. As a matter of fact it is the universal solvent. You see, we've been misled to believe it hydrates us but it doesn't it cleans us. Let's face facts here and bring up the point that if one drinks too much water it can kill them so if it's hydrating how does that work? People will tell you to drink "purified" water but what is that? It was distilled water before it was run through a facility adding all sorts of contaminates and then chemicals were added to "make it clean." I think I'll pass as it's these additives that are hurting people over time. Others say drink only "spring" water? What is that? It's distilled water that fell from the sky (rain) and turned into "spring" water by hitting the ground and/or traveling on the mudball or through it picking up "dead organics" along the way. I'll pass. The body doesn't need nor want chemicals or dead organics mixed into it as the body will just have to filter these things out or it gets to a point where it can't becoming more and more acidic creating all the known dis-eases any of us suffer from. Water is really just the tip of the iceberg buts it's a great place to begin as, again, we are 72% water. Controlling our water's makeup within us is huge and life changing. You want more info check out Dr. Cassar on YT and search for his vids on water. Like I said, water is a solvent meant to draw out toxins and clean the body. So if the water is already, let's say 50% full of things such as chemicals and dead organics or whatever it can only do half it's job not to mention your bringing in these new pollutants as you consume it. Great question by the way. I've consumed only distilled water for about 7 years ie drinking/cooking and I'm still alive and much healthier.
