In a study published in Nutrition Today, researchers investigated opinions of low-income individuals about organic versus conventional fruits and vegetables and found that their choices are impacted by the amount of messaging they are receiving, such as EWG's Dirty Dozen. These people felt that organic was better, but because of the cost, were more willing to forgo fruits and vegetables because of cost even though there were lower cost conventionally grown produce.
This is a topic that has been addressed from a health standpoint, where organic was found to be no more nutritious than conventional, and more importantly from a safety standpoint, whether biological contaminates or those that can lead to cancer. USDA testing has continually shown that pesticide levels in produce are within established limits.
The issue is that many are missing the health benefits of having produce in their diet for the sake of avoiding some infinitesimal risk.
