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.
国家营养指南强调食用富含营养的水果和蔬菜（PFV），即那些与降低慢性病风险密切相关的食物；然而，目前仍缺乏对PFV进行定义的相关工作。本研究制定并验证了一种分类方案，将PFV定义为每100千卡能量中平均能提供17种合格营养素每日摄入量10%或更多的食物。在研究的47种食物中，有41种符合富含营养的标准，并且比非PFV食物的营养密度更高，这为该分类方案的有效性提供了初步证据。所提出的分类方案可作为营养教育和饮食指导的工具。
