Soda companies already have nutritional information on their products, but now, they're going a step further.

Coke, Pepsi and Dr. Pepper will now start putting nutritional information on the vending machines.

The move comes ahead of a regulation that would require restaurant chains and vending machines to post the information.

The American Beverage Association said the calorie counts will be on the buttons people press to select a drink.

Vending machines will also feature small decals, such as "Calories Count: Check Then Choose."

Will that make you think twice before purchasing a soda? Or do you feel people are already aware of the calories in a can of soda and it won't matter?
