Summary
This WHO guideline provides evidence-based recommendations on potassium intake for adults and children, drawing on systematic reviews of the relationship between dietary potassium and blood pressure and cardiovascular outcomes. It recommends a potassium intake of at least 3,510 mg/day for adults, noting that higher intakes are associated with reduced blood pressure and lower risk of stroke and coronary heart disease. The document is intended to inform national nutrition policies and dietary guidelines worldwide.
UK applicability
Directly applicable to UK nutrition policy; the guideline informs UK dietary reference values and public health messaging on potassium, particularly in the context of cardiovascular disease prevention. UK intakes are generally below the recommended threshold, making this guidance relevant to NHS and SACN dietary advice.
Key measures
Recommended daily potassium intake (mg/day); blood pressure outcomes; cardiovascular disease risk; urinary potassium excretion as intake proxy
Outcomes reported
Sets out evidence-based recommendations for adequate daily potassium intake to reduce blood pressure and risk of cardiovascular disease in adults and children. Reports on intake thresholds associated with health outcomes across population groups.
