I have never used these lists before, I think I've heard of them before, but never paid attention to them. I definitely didn't realize that a lot of the fruits and vegetables that were on the dirty dozen list are a lot of what I've been buying and eating, like strawberries, spinach, grapes. There are a few on the clean fifteen list that I buy, but most came from the dirty dozen list. The next time I go grocery shopping, I will definitely have these lists handy because I definitely wouldn't want to be ingesting so many pesticides.
