Posting calories counts on menus isn’t necessarily making consumers choose healthier options, but a new study has found that if told what they would have to do to burn off those calories, teens are less likely to buy higher calorie or sugary drinks. When signs were posted in stores telling buyers things like, “Did you know that working off a bottle of soda or fruit juice takes about 5 miles of walking,” 40% of 12-18-year-olds who saw them said they changed their drink choice as a result. Even after the signs were removed these teens continued to make healthier choices. (Washington Post)
