We know there is a lot of debate about organic groceries and whether they really are any better for you. Here at The Holist, we try to buy organic as much as possible, but we appreciate it's pretty expensive and it's not always possible to buy 100% organic. 

Not to worry, the lovely people at the Environmental Working Group (the "EWG") have helpfully come up with the "Dirty Dozen" and the "Clean Fifteen" lists to help us. The EWG has analysed pesticide residue testing data from the U.S. Department of Agriculture and Food and Drug Administration to come up with a ranking system for the most popular fresh produce items. The Dirty Dozen are those items which have the highest rates of pesticide contamination and the ones you should try to buy organic as far as possible. At the other end of the spectrum, the Clean Fifteen have the lowest rates of contamination so if you're having to priortise which produce to buy organic then you can skip these.
