You really need to be careful to supplement with the minerals you would have otherwise picked up from tap water. People get a lot of calcium, potassium etc passively through groundwater / natural water sources. There's a reason people are advised away from drinking distilled water. (not to mention fluoridation, but that's a separate can of worms I won't open)
