Finally!  A positive use for marketing!  The USDA is using marketing to "trick" children into choosing the healthy options when they go to the school cafeteria.  Some of their tricks:

 This seems like a great idea to me, but maybe even better would be to make sure that all the food served is healthy and appealing.  Northampton's Bridge Street School is taking a step in that direction with "Fresh Wednesdays," when they serve only freshly-made locally-produced food.  Here's a photo of one of their offerings:
