Is it true that a higher dietary potassium intake relative to sodium intake is associated with a lower risk of cardiovascular disease?
Yes. A 2025 systematic review and meta-analysis of cohort and randomized studies found that a higher estimated dietary sodium-to-potassium ratio was associated with a higher risk of cardiovascular events and mortality in the general population. Reference and consensus sources likewise report that higher potassium intake relative to sodium is linked to lower cardiovascular risk, though several items address blood pressure or hypertension rather than cardiovascular disease itself.
