Overview

The Dietary Patterns Subcommittee conducted systematic reviews to address 8 questions that examined the relationship between dietary patterns and health outcomes: 

  1. What is the relationship between dietary patterns consumed and growth, size, body composition, and risk of overweight and obesity?
  2. What is the relationship between dietary patterns consumed and risk of cardiovascular disease?
  3. What is the relationship between dietary patterns consumed and risk of type 2 diabetes?
  4. What is the relationship between dietary patterns consumed and risk of certain types of cancer?
  5. What is the relationship between dietary patterns consumed and bone health?
  6. What is the relationship between dietary patterns consumed and neurocognitive health?
  7. What is the relationship between dietary patterns consumed and sarcopenia?
  8. What is the relationship between dietary patterns consumed and all-cause mortality?

These reviews can be accessed below, and are discussed in the Scientific Report of the 2020 Dietary Guidelines Advisory Committee, Part D: Chapter 8, which is available at DietaryGuidelines.gov.
For information on all systematic reviews conducted by the 2020 Dietary Guidelines Advisory Committee with support from NESR, including details about NESR’s systematic review methodology, see the 2020 Dietary Guidelines Advisory Committee Systematic Reviews Page.

Every systematic review contains a summary, description, and synthesis of the evidence, data and risk of bias tables, graded conclusion statements, and research recommendations. The systematic review also details the protocol used in conducting the systematic review, including the analytic framework, inclusion and exclusion criteria, literature search strategy, searching and screening results, and lists of included and excluded articles. In addition, both a technical abstract and plain language summary are provided for each of the systematic reviews.
