As long as you're eating a varied diet (such as eating a good variety of plants) drinking demineralized water really isn't an issue. I've been eating plant based whole food lately and at 1903 kcals yesterday I managed (per Cronometer): - 646.4mg of calcium - 636.1mg of magnesium - 785.1mg of sodium Which are the 3 big ones in common tap water. Even if you factor in a 25% error margin, through my diet I'm getting way more than I would drinking random tap water.
