If you've heard the term "organic" a million times but still aren't sure what it means, here's the deal: Organic farming avoids the use of most artificial inputs, like synthetic pesticides and fertilizers, and bans the use of animal by-products, antibiotics and sewage sludge. But check for tricky labeling: "100% organic" actually means that all the individual ingredients are organic. "Organic" means that at least 95% of the ingredients are organic. "Made with organic ingredients" means that at least 70% of the ingredients are organic. Check your local farmers market, Community Supported Agriculture (CSA) project, neighborhood food co-op, and natural food stores when looking for organic foods.
