Gatorade Bad For You?
The University of Iowa researchers covered extracted teeth with nail polish. They left bare two 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, or 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.

On the roots of the teeth, Gatorade was more corrosive than Red Bull. Coke, apple juice, and Diet Coke followed in that order.
The difference in the effect isn’t simply due to their sugar content. Gatorade is 6% carbohydrates, mostly sugars. Coke is about 10% sugar. Both are acidic beverages.
