This book is based on the recommendations put forward by the 2010 Dietary Guidelines Advisory Committee. The Committee was composed of scientific experts who reviewed and analyzed the most current information on diet and health and incorporated it into a scientific, evidence-based report. This book presents the most recent scientific evidence review and provides information and advice for choosing a healthy eating pattern, namely, one that focuses on nutrient-dense foods and beverages, and that contributes to achieving and maintaining a healthy weight. Such a healthy eating pattern also embodies food safety principles to avoid foodborne illness. The 2010 Dietary Guidelines are intended to be used in developing educational materials and aiding policymakers in designing and carrying out nutrition-related programs, including Federal nutrition assistance and education programs. The Dietary Guidelines also serve as the basis for nutrition messages and consumer materials, developed by nutrition educators and health professionals for the general public and specific audiences, such as children.
