A new website that launched this week: smarterlunchrooms.org. Its goal is to design sustainable lunchrooms that guide smarter choices. Simply replacing pizza with whole-wheat flatbreads and fries with roasted sweet potatoes doesn’t allow kids to learn how to make real-world choices, says David Just, from Cornell University. We set it up so that everything is available and the kids are enabled to see how to make decisions. Making those decisions, he says, leads to good habits.
