School food: the cupcake problem?

Today’s New York Times quotes me discussing the “cupcake problem,” the deal breaker in many attempts to get junk foods out of schools. I don’t have anything against cupcakes–I love them too–but in reasonable frequency and size. Friends with school-age children tell me the kids are bombarded with sweets in school for birthdays, rewards, trades, and treats. Cupcakes have become the flash point for arguments about who should control what kids eat. I, of course, think schools should set a good example. Your thoughts?
