The United States Department of Agriculture reports that "Fruits and Vegetables Top Organic Food Sales". Fresh fruits and vegetables accounted for 40% of total organic food sales in 2015, followed by dairy.
Confused about whether to buy organic? The Environmental Work Group (EWG) has helpful resources to answer this question when it comes to fruits and vegetables. In a nutshell, it depends. Some conventionally grown fruits and vegetables have low levels of pesticide residue. These are deemed by EWG as the Clean Fifteen. No need to buy organic versions of these. Others are more likely to contain hefty doses of pesticides. Buy organic versions of the Dirty Dozen to avoid pesticide exposure. And wash produce before enjoying it.
