Getting a little off topic here, but the study on tooth decay I mentioned was called "Dissolution of dental enamel in soft drinks", by J. Anthony von Fraunhofer, MSc, PhD, FADM, FRSC, and Matthew M. Rogers, DDS.
Here were a few of the results of interest (note that lower pH means higher acidity, pH of 7 is neutral, <7 acidity, >7 base):
Beverage / pH / 14-day weight loss %
Coca-Cola / 2.48 / 1.39
Pepsi-Cola / 2.46 / 1.40
Dr. Pepper / 2.90 / 1.72
Mountain Dew / 3.14 / 6.17
Diet Mountain Dew / 3.27 / 8.01
Sprite / 3.27 / 3.93
Canada Dry ginger ale / 2.94 / 3.48
A&W root beer / 4.80 / 0
Arizona iced tea (canned) / 2.94 / 4.86
Brewed black tea / 5.36 / 0.22
Brewed black coffee / 6.25 / 0.19
Tap water / 6.70 / 0
I don't drink Mt. Dew anymore because of this study.
