Teens from JP join in fitness classes and games as part of the soda industry’s “Mixify Truck Tour” July 14 at the Roxbury YMCA. Sponsored by Coca-Cola, Pepsico, Dr. Pepper Snapple Group and the American Beverage Association in response to criticisms of links between soda and childhood obesity, the national program attempts to tell teens to balance soda-drinking with exercise. The program has been criticized as promoting sugary drinks along with unrealistic presentations of how much exercise is needed to burn off the amount and type of calories they contain.
