This guide was just released from the EWG this week. This list is complied using data released from the USDA. I really appreciate this is because not only is it diffcult to always find, grow, or purchase organic produce, it can be expensive too. Some of these really surprised me, I kind of figured as much about grapefruit and avocados, things with skins you don't consume; but the asparagus and mushrooms are good to know about.
But one thing is for sure. Don't pass up fruits and vegetables because you are worried about pesticides. See it as a classic good, better, best. Eating lots fresh produce is good, "clean" conventionally grown items are better, and organic, pesticide and chemical-free is best. Purchase and eat what you can, just see that you do, because blue-raspberry otterpops are not an even exchange for a handful of the real thing.
