Gatorade destroys your teeth faster than Coke?
The University of Iowa researchers covered five extracted teeth with nail polish. They left two bare patches on each tooth, one on the enamel and one on the root. Then they dunked the teeth in test tubes filled with regular Coke, Diet Coke, Gatorade, Red Bull and 100% apple juice.

Every five hours, the researchers refreshed the beverages. After 25 hours, they examined the teeth with a microscope. All of the beverages eroded the bare spots on the teeth. But different beverages had significantly different effects.

On the enamel, Gatorade was significantly more corrosive than Red Bull and Coke. Red Bull and Coke, in turn, were significantly more corrosive than Diet Coke and apple juice.
