Why can people not safely drink 100% ultra pure water?

Question

I don’t know if it’s like it could hurt you from drinking it at all or if you just can’t drink it for sustained periods of time

Answer 1

There’s nothing innately harmful about drinking pure water. I have to, per doctor’s orders, to deal with kidney stones complicated by mineral-rich water. For over 20 years, 4L per day of either purchased distilled water or from a reverse osmosis filter in my kitchen. With a decently healthy diet, any minerals I lack from water I get from other sources.
Taste-wise, it is a bit bland but not offensive. Reverse-osmosis filter systems can include re-mineralizers to add flavorful minerals back into the purified water (mine doesn’t).
