Part III
Part III of this report presents the evidence the committee reviewed to derive the Dietary Reference Intake (DRI) values for sodium. Based on the committee’s review of the evidence on indicators of adequacy, toxicity, and chronic disease as they relate to sodium, the committee provides its recommendations. This part of the report consists of four chapters.
Chapter 8 follows steps 1 and 2 of the DRI organizing framework, provides the committee’s review of the evidence on indicators of sodium adequacy, and presents the committee’s rationale for updating some of the previously established Adequate Intake values.
Chapter 9 follows steps 1 and 2 of the DRI organizing framework, provides the committee’s review of the evidence on indicators of sodium toxicity, and presents this committee’s rationale for not establishing a Tolerable Upper Intake Level under the expanded DRI model.
Chapter 10 follows steps 1 and 2 of the DRI organizing framework, provides the committee’s review of the evidence on the relationship between sodium intake and chronic disease risk, and provides the committee’s rationale for establishing the sodium Chronic Disease Risk Reduction Intakes.
Chapter 11 follows steps 3 and 4 of the DRI organizing framework by characterizing risk in the U.S. and Canadian populations and by describing special considerations and public health implications, as they relate to the revised sodium DRI values.
