Buying organic makes sense for the health of the earth, farm workers and your family ... but if you're pinching pennies (and who isn't these days?), choose from this list to avoid the foods with the most pesticide residue.
Onions don't see as many pest threats, which means less pesticide spraying.
Avocados have thick skins that protect the fruit from pesticide build-up.
