4. Your Teeth
We all know sugar is bad for our teeth. That’s something that’s probably been drummed into us since we first learned how to talk. Soda has more than its share of sugar for sure, but what you may not know is that it also contains acids that can contribute to the erosion of the enamel on your teeth. That makes soda doubly bad for your choppers, and once again, diet soda is no exception because it contains the same acids.
