Implementation science (IS) is the study of approaches designed to increase adoption and sustainability of research evidence into routine practice. This article provides an overview of IS and ideas for its integration with nutrition education and behavior practice and research. Implementation science application in nutrition education and behavior practice can inform real-word implementation efforts. Research opportunities include advancing common approaches to implementation measurement. In addition, the article provides suggestions for future studies (eg, comparative effectiveness trials comparing implementation strategies) to advance the knowledge base of both fields.
