The committee answered this public health question: what is the association between dietary patterns consumed and all-cause mortality (ACM)? OBJECTIVE To ascertain the association between dietary patterns consumed and ACM.

Non-communicable diseases (NCDs), which include cardiovascular disease, cancer, and diabetes, all of which are associated with the common risk factors of poor diet and insufficient physical activity, caused 63% of all deaths globally in 2008. The increasing discussion of global NCDs, including at the 2011 United Nations General Assembly High-level Meeting on the Prevention and Control of Non-communicable Diseases, and a request for multi-stakeholder engagement, prompted the International Food Information Council Foundation to sponsor the Global Diet and Physical Activity Communications Summit: “Insights to Motivate Healthful, Active Lifestyles” on September 19, 2011, in New York City. The Summit brought together a diverse group of stakeholders, representing 34 nations from governments; communication, health, nutrition, and fitness professions; civil society; nonprofits; academia; and the private sector. The Summit provided expert insights and best practices for the use of science-based, behavior-focused communications to motivate individuals to achieve healthful, active lifestyles, with the goal of reducing the prevalence of NCDs. Presented here are some of the highlights and key findings from the Summit.

The recently released 2015-2020 Dietary Guidelines for Americans (DGA) 1 serves as our nation's nutrition policy backbone and an essential resource for health and nutrition professionals. Registered dietitian nutritionists (RDNs) rely on the evidence-based recommendations to help the public they serve make informed food and beverage choices. Now in its eighth edition, the DGA function as a roadmap to guide Americans ages 2 years and older in preventing diet-related health conditions like obesity, type 2 diabetes, heart disease, and some cancers. The DGA are also used in developing federal food, nutrition, and health policies and programs and serve as the basis for federal nutrition education materials for the public. Produced by the US Department of Agriculture (USDA) and US Department of Health and Human Services, the DGA are updated every 5 years to reflect advancements in scientific knowledge and to translate the current science into food-based guidance to promote health in the United States.
