Overview

The Dietary Fats and Seafood Subcommittee conducted 4 systematic reviews that examined the relationship between dietary fats and seafood and health outcomes: 

  1. What is the relationship between types of dietary fat consumed and risk of cardiovascular disease? 
  2. What is the relationship between seafood consumption during pregnancy and lactation and neurocognitive development in the child?
  3. What is the relationship between seafood consumption during childhood and adolescence (up to 18 years of age) and neurocognitive development?
  4. What is the relationship between seafood consumption during childhood and adolescence (up to 18 years of age) and risk of cardiovascular disease?

These reviews can be accessed below, and are discussed in the Scientific Report of the 2020 Dietary Guidelines Advisory Committee, Part D: Chapters 2, 3, and 9, which are 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.
