There is some research that shows it's bad to drink water that has low dissolved solids, though. So you might want to put some minerals back into the water you drink. I can't really find conclusive evidence that it's bad, though. But you can look into it. You'd have this problem if you drank rain water for example, so low mineral water isn't unnatural or anything.
