"I'm not sure whether or not people really want all this healthy food, or whether or not Starbucks or these places are saying we should be doing this stuff because it's the right thing to do," said John Stanton, a professor of food marketing at Saint Joseph's University in Philadelphia. "People are still not eating fresh fruits and vegetables. Obesity is still an epidemic. Who are these people eating all these healthy foods?"
Mr. Stanton says healthy food marketing works in the short term because thin foods enable companies to provide less product and make more money, but he questions the long-term viability of the marketing strategies.
