Why are there ingredients for my water??!
Answers: Isn't anything what it's supposed to be? Can't I just get me some pure water?
Yeah, you'd get distilled water. But it might not be what you're used to. The "flavor" in water come from the trace minerals in it, and tap water has fluoride which is good for your teeth and is where a majority of people get their flouride from in their diets. Water is rarely ever "pure", and is not necessarily a "healthier" choice in the long run.
probably stuff to purify it
Some waters add minerals to improve taste.
Blame it on the Food Cops. They want labels on EVERYTHING. They even have a CALORIE count on water: which I hope is always ZERO.
