You can hardly turn on the TV any more without seeing some kind of a message about healthy eating. Jamie Oliver is trying to change school cafeterias in his “Food Revolution” series while “The Biggest Loser” shows contestants learning to eat right and exercise to lose weight. In between shows on the Disney Channel, my kids love watching “Captain Carlos” and “Tasty Time With ZeFronk,” both shorts that target healthy eating for the preschool set. We might enjoy watching this type of programming, but are our kids truly taking the healthy eating message to heart? Despite all of the publicity, the figures Joann cited in her Battle of the Bulge post are astounding. Our kids don’t seem to be getting any thinner.
