Think your groceries are getting too expensive? Last winter, residents of a remote Canadian village were paying $28 for a head of cabbage and $65 for a pound of chicken. It's unlikely such absurd food prices will trickle south, but they are creeping up--and when food prices rise, diets typically tank. That's ironic, too, because some of the healthiest foods in the world are also among the cheapest. Even eating organic isn't all that much more expensive, when you stick with basics and get creative with your cooking. So put down the 99-cent can of Beefaroni and grab one of these cheaper, healthier alternatives.
