Alice Waters, of Berkeley's famed restaurant Chez Panisse, has started a great project for schoolchildren: The Edible Schoolyard. The program is designed to teach children to grow their own food, in an effort to educate them about nutrition and change eating habits for the good. It's similar to Jamie Oliver's Feed Me Better campaign, kicked off in Britian several years ago, but adds the fantastic idea of actual, hands-on gardening.
I love programs like this; the closer you get to your food - where it comes from, how it's prepared - the better you'll eat. This is true for adults and certainly true for children, many of whom have absolutely no idea how food ends up on their plates. If you let kids get their hands dirty, do things for themselves, they not only have a greater appreciation of the effort it takes to turn a seedling into a salad, they'll be more interested in eating the salad as well. After all, it's theirs, and we all know how kids feel about "mine!"
