Two nutrition experts argue that you can't take marketing campaigns at face value

With America's obesity problem among kids reaching crisis proportions, even junk food makers have started to claim they want to steer children toward more healthful choices. In a study released earlier this year, the Centers for Disease Control and Prevention reported that about 32 percent of children were overweight but not obese, 16 percent were obese, and 11 percent were extremely obese. Food giant PepsiCo, for example, points out on its website that "we can play an important role in helping kids lead healthier lives by offering healthy product choices in schools." The company highlights what it considers its healthier products within various food categories through a "Smart Spot" marketing campaign that features green symbols on packaging. PepsiCo's inclusive criteria--explained here--award spots to foods of dubious nutritional value such as Diet Pepsi, Cap'n Crunch cereal, reduced-fat Doritos, and Cheetos, as well as to more nutritious products such as Quaker Oatmeal and Tropicana Orange Juice.
