2015 Dietary Guidelines Advisory Committee 


Subcommittee: Dietary Patterns, Foods and Nutrients, and Health Outcomes

List of NEL Systematic Review Questions

Dietary patterns and their food and nutrient characteristics are at the core of the conceptual model that has guided the 2015 Dietary Guidelines Advisory Committee’s work (see Scientific Report of the 2015 Dietary Guidelines Advisory Committee: Part B. Chapter 2: 2015 DGAC Themes and Recommendations: Integrating the Evidence), and the relationship of dietary patterns to health outcomes is the centerpiece of this section. The Committee considered evidence about the relationship of diet with several health outcomes that are listed as major public health outcomes of concern in Scientific Report of the 2015 Dietary Guidelines Advisory Committee: Part D. Chapter 1: Food and Nutrient Intakes, and Health: Current Status and Trends. Several of these outcomes—cardiovascular disease, overweight and obesity, type 2 diabetes, congenital anomalies, and bone health—also were addressed by the 2010 Dietary Guidelines Advisory Committee.  Others—cancers (lung, colon, prostate and breast) and neurological and psychological illness—while previously addressed, are considered here in more depth and represent an expanded list of health outcomes for which there is growing evidence of a diet-disease relationship.
 
For additional information, see Scientific Report of the 2015 Dietary Guidelines Advisory Committee: Part D. Chapter 2: Dietary Patterns, Foods and Nutrients, and Health Outcomes.  Information in the report was vetted by the full committee and presented at public meetings; however, more detailed supporting information on each specific systematic review is available on the NEL website. Below are links to the questions this Subcommittee answered using a NEL systematic review approach.
