Since growing season is here, I though I'd share the Environmental Working Group's Shopper's Guide to Pesticides in Produce. Since not everyone is able to buy all organic food, this guide shows which produce is highest in pesticides and thus should be avoided. In addition, I recommend avoiding genetically modified foods (GMOs) whenever possible by buying organic. Some of the worst offenders are soy, corn, and canola.
