Have you heard of the Dirty Dozen and the Clean Fifteen? It's a list of fruits and vegetables that are the most and least contaminated by pesticide use, according to the Environmental Working Group. Pesticides have been linked to a variety of health problems, including hormone disruption, cancer and brain toxicity. With that in mind, I try my best to buy organic (and local) foods when I can, but if that's not possible, I always think back to this list. I found a handy little infographic that includes the entire list of clean and dirty produce. I hope it's as useful to you as it is to me.
