By Jennifer Di Noia, PhD - <br><br>National nutrition guidelines emphasize consumption of powerhouse fruits and vegetables (PFV), foods most strongly associated with reduced chronic disease risk; yet efforts to define PFV are lacking. <br><br>This study developed and validated a classification scheme defining PFV as foods providing, on average, 10% or more daily value per 100 kcal of 17 qualifying nutrients. Of 47 foods studied, 41 satisfied the powerhouse criterion and were more nutrient-dense than were non-PFV, providing preliminary evidence of the validity of the classification scheme. The proposed classification scheme is offered as a tool for nutrition education and dietary guidance.<br><br><a href="http://www.cdc.gov/pcd/issues/2014/13_0390.htm">READ MORE ON CENTERS FOR DISEASE CONTROL AND PREVENTION</a><br><br>Di Noia J.
