Should Foods Display Exercise Labels?

BOSTON (CBS) -- We've heard the push for more nutritional information on labels and menus, but some experts suggest something different.

British researchers think food packaging should include exercise labels as well as calorie counts. They might appear as pictures or symbols that would say you would have to run for 15 minutes or walk for 30 minutes to burn off a sugary soda or a candy bar.

Experts think the information may do a better job of discouraging people from indulging because the labels would be easier to understand than regular nutrition labels.
