TY - JOUR AU - Di Noia, Jennifer PY - 2014 TI - Defining Powerhouse Fruits and Vegetables: A Nutrient Density Approach T2 - Preventing Chronic Disease JO - Prev Chronic Dis SP - E95 VL - 11 CY - Centers for Disease Control and Prevention, Atlanta, Georgia 30333, USA. N2 - 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. 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. SN - 1545-1151 UR - http://dx.doi.org/10.5888/pcd11.130390 DO - 10.5888/pcd11.130390 ER -
