Certain kinds of produce carry a heavy toxic load if they are grown with conventional methods that include pesticides. Others, for different reasons in how they are raised or what kind of skin/rind they form, do not. This PBS article has more detail but here are the two lists for quick reference.
We should only buy these “Dirty Dozen” organic:
- domestic blueberries
- sweet bell peppers
- spinach, kale and collard greens
- imported grapes
These “Clean 15” are safe to consume conventionally:
- sweet corn
- sweet peas
- kiwi fruit
- sweet potatoes
- sweet onions
Besides the direct toxic effects of pesticides on our bodies, there are plenty of other reasons to support balanced organic farming. But if we’re looking for a place to start, this list is a great one!
