Teaching children the importance of both locally grown and seasonal foods is a route to educating them about the Earth and their own health. Lead by example by preparing meals that incorporate in-season produce. Not only will your food taste better, you'll also find it's more cost-effective. "When produce is in season locally, the relative abundance of the crop usually makes it less expensive," noted chef Jennifer Booker, founder of the website Your Resident Gourmet. Because local, in-season produce doesn't have to travel far, it also retains more flavor, and that makes it just plain delicious.
