8. Sports Drinks
The manufacturers of these drinks would have you believe that you’d never be able to complete a marathon or even a company softball game without plenty of their product on hand to keep you going. The truth of the matter is that you are probably much better off with plain water instead of all the artificial ingredients that are in many sport drinks. In addition to that, many of them are pretty acidic, which can erode tooth enamel and make your choppers more susceptible to staining.
