Abstract
The purpose of a systematic evidence-based review is to integrate the best of the research literature in an objective manner. Although this approach has been used in a number of nutrition content reviews, reviewing food- and nutrition-related behaviors presents a different set of challenges. The 2010 Dietary Guidelines Advisory Committee followed the American Dietetic Association systematic method for an evidenced-based review as closely as possible. This article examines the steps that the committee used to generate the advisory recommendations for the dietary guidelines, identifies the difficulties in application, and suggests changes to the process for the next cycle of review.
