To the Editor Dr DeSalvo and colleagues concluded that dietary patterns should align with the eighth edition of the Dietary Guidelines for Americans.1 However, I disagree with the recommendation to reduce sodium intake to less than 2300 mg/d. As a member of the Institute of Medicine (IOM) Committee on Sodium Intake in Populations, I also disagree with the characterization in the Viewpoint that the IOM report generally recommends sodium reduction. This report recommended reduction of “excessive” sodium intake (without defining “excessive”) but specifically concluded, “Science was insufficient and inadequate to establish whether reducing sodium intake below 2300 mg/d either decreases or increases cardiovascular disease risk in the general population.”2 Consequently, this report does not support the 2300-mg/d upper level recommended by the Dietary Guidelines.
