What Does Evidence-Based Mean for Nutrition Educators? Best Practices for Choosing Nutrition Education Interventions Based on the Strength of the Evidence.

Funding agencies and professional organizations are increasingly requiring community-based nutrition education programs to be evidence-based. However, few nutrition education interventions have demonstrated efficacy, particularly for interventions that address the outer layers of the socioecological model (ie, organizational, community, and public policy). This article reviews the types of evidence available to assess the likelihood that a given intervention will deliver the desired outcomes and how these types of evidence might be applied to nutrition education, and then suggests an approach for nutrition educators to evaluate the evidence and adapt interventions if necessary.
