Vitamins, minerals, enzymes and other micro-nutrients - eating fruits and vegetables can keep us healthy.

In Part 2 of News 12's Earth Week series, Elizabeth Hashagen takes a look at one list that aims to help you choose when to go organic with your groceries.

Each year, the Environmental Working Group (EWG) releases an updated Shopper's Guide to Pesticides in Produce.

According to the EWG, the Dirty Dozen is a list of the 12 fruits and vegetables that contain the highest concentrations of pesticides, which the EWG recommends buying organic. The Clean Fifteen, is a list of 15 fruits and vegetables that contain the fewest concentrations of pesticides, which the EWG believes are the safest foods to buy conventionally.

The lists are assembled based on data from tests recently conducted by the United States Department of Agriculture (USDA).
