After watching Super Size Me, my twelve year old only wants to eat farm to table foods. We'd like to take it a step further and really teach our kids about sustainable eating. If you have any suggestions, comments, experience, etc., please share.
I don't have any kid, but if you want to teach them about sustainable eating, here's what I'm thinking of:
Watching "Super Size Me" with them was one (good) thing, but I think kids would need some sort of unique experience: take yours to a farmer's market.
Your kid will have the chance to eat good samples, to actually taste good local food. I go every week to a farmer's market, and I get to eat delicious things (eg: apple butter, or spinach samosas...). It's a pleasant and unique experience that makes me want to go back there every week.
Even though food is a bit pricey, it's great to help local farmers, and going to this market has nothing to do with the boring, yet mandatory task to go to the overcrowded grocery stores.
