I don’t always buy organic fruits and veggies. It depends on the prices, and how much of the food I’m going to eat, and how easy the surface is to wash. And also taste! Organic strawberries and carrots taste so much better than conventional!
But another factor is which foods tend to be most pesticide-laden. Every year, the Environmental Working Group puts together a handy two-part report card called the “Dirty Dozen” and the “Clean Fifteen.”
Here’s the list for 2015. (It usually doesn’t change much from year to year. But you can always google “clean fifteen” for the given year.)
