Part II
Part II of this report presents the evidence the committee reviewed to derive the Dietary Reference Intake (DRI) values for potassium. Based on the committee’s review of the evidence on indicators of adequacy, toxicity, and chronic disease as they relate to potassium, the committee provides its recommendations. This part of the report consists of four chapters:
Chapter 4 follows steps 1 and 2 of the DRI organizing framework, provides the committee’s review of the evidence on indicators of potassium adequacy, and presents the committee’s rationale for revising the previously established Adequate Intake values.
Chapter 5 follows steps 1 and 2 of the DRI organizing framework, provides the committee’s review of the evidence on indicators of potassium toxicity, and presents this committee’s rationale for not establishing a potassium Tolerable Upper Intake Level under the expanded DRI model.
Chapter 6 follows steps 1 and 2 of the DRI organizing framework, provides the committee’s review of the evidence on the relationship between potassium intake and chronic disease risk, and provides the committee’s rationale for not establishing a potassium DRI based on chronic disease.
Chapter 7 follows steps 3 and 4 of the DRI organizing framework by characterizing risk in the U.S. and Canadian populations and describing special considerations and public health implications, as they relate to the revised potassium DRI values.
