In this issue of the Archives, Yang et al¹ report on their analysis of the relationship between mortality and usual intakes of sodium and potassium. Among more than 12 000 US adults whose dietary intake was assessed in the Third National Health and Nutrition Examination Survey (NHANES III), they identified large relationships between higher sodium intake and higher all-cause mortality and between lower potassium intake and higher all-cause, cardiovascular (CVD), and ischemic heart disease (IHD) deaths. Most important, higher sodium to potassium ratios were strongly associated with increased all-cause, CVD, and IHD mortality.

This article strengthens the already compelling evidence of the relationship between sodium intake and mortality. A considerable body of work supports the links between higher sodium and lower potassium intake and hypertension, cardiovascular events, and mortality.² Some studies diverge, such as that by Cohen et al.³ However, . . .
