Higher sodium intake is associated with an increased risk of stroke, stroke mortality, and coronary heart disease mortality in adults.

While direct mortality data from trials is limited, observational evidence suggests that high sodium intake increases the risk of stroke and heart disease death. Maintaining moderate sodium levels supports long-term cardiovascular health.

ModerateSupportsMEDIUM confidence
Increased sodium intake was associated with an increased risk of stroke (risk ratio 1.24, 95% confidence interval 1.08 to 1.43), stroke mortality (1.63, 1.27 to 2.10), and coronary heart disease mortality (1.32, 1.13 to 1.53).

Why this rating

Evidence is derived from cohort studies, which are rated 'low' or 'very low' quality by GRADE due to observational design, though the association is statistically significant.
