I second that 0 ppm water is bad, if you drink DI'ed water at 0ppm you body will draw minerals from bones and blood, its not immediately lethal of course, but I would not drink it for sure.
Good rate is about 150-200ppm I drink bottled water sometimes 2000 or more ppm but no longer then a week.
So for drinking: RO tap water is ok DI not good.
