One thing I've had trouble with was deciding to buy organic or not. Of course, organic is no doubt healthier, but some things hold more pesticides than others anyways. Wouldn't it be great to know what fruits and vegetables were worth the extra financial cost?
The day after I was mulling this over, I found this adorable cheat sheet! It's available to be printed off, and has the good produce on one side and the "dirty dozen" on the other, complete with illustrations for the illiterate.
I've got to go grocery shopping, because I've been slack in my duties the last couple days, what with the two weddings I am in over the next two weeks. :)
