SUGAR SHOCK: Coco-Cola Co., PepsiCo Inc. and Dr Pepper Snapple Group Inc. say they'll start posting calorie counts on vending machines starting next year.
A LITTLE CONTEXT: The move comes ahead of a regulation that could require restaurant chains and vending machines to post calorie information.
NITTY GRITTY: The new vending machines will first be available in Chicago and San Antonio, as part of a wellness initiative for city employees, before rolling out nationally. The beverage industry hasn't set a timetable for when the rollout will be complete.
