Since 1998, Americans have been wising up. Based on data from the industry publication Beverage Digest, per capita consumption of “carbonated sugar drinks” (which includes regular soda and energy drinks, but not sports drinks, fruit drinks, ades, teas, and sugary waters) dropped by a remarkable 25 percent. Regular Coke is down by 34 percent and Pepsi by an astounding 51 percent.
