We're usually too wrapped in in calories to consider another important factor to what we're drinking -- the acidity. Acidic drinks can not only lead to ulcers, but they can rot your teeth too. Fitsugar has a handy breakdown of the worst offenders acid-wise. What are the some of the worst offenders?

• Coke, with a pH of 2.63
• Pepsi at 2.49
• Gatorade at 2.95
• Doctor Pepper at 2.95
• Minute Maid at 2.8

For comparisons sake, consider this: Neutral pH (water) is 7.0. Battery Acid is 1.0 and you mouth's normal pH should be about 6.2-7.0. So if you haven't quit drinking soda for the sake of your health, maybe you should consider giving it up for the sake of your pearly whites?
