I found this wonderful little cheat sheet over at fooducate.com to clip out and stick in your purse or wallet. A great reminder while shopping which fruits and vegetables you should buy organic whenever possible, and which you can opt for the ( lower cost ) non-organic versions. Obviously, you should wash all food carefully before consuming - but those on the Dirty Dozen you need to be particularly careful with...they can contain much more pesticides per serving than anyone should be consuming, regardless of how clean a diet you are consuming!
