RO or RO/DI for drinking water?

actualy the biggest concern with drinking DI (which should be mentioned) is the possibility of bacterial growth in the resin its self as the chlorine has been stripped out so there is nothing to prevent growth, but on the other hand the water is pure so growth is limited.

also the water can't adsorbe minerals from your body as that is a bilogical process, but the biggest concern which was mentioned by windcoast, is that it can fail to be able to replenish the salt and electrolites lost due to sweat, but as mentioned unless you have some medical condition which prevents your body from adsorbing these from the food you eat it is of little concern for 99.99999999% of the population
