Research Paper Title

Effect of Increased Potassium Intake on Cardiovascular Risk Factors and Disease: Systematic Review and Meta-analyses.

Study Question

What are the effects of increased potassium intake on blood pressure, mortality and morbidity from cardiovascular diseases, and incidence of adverse effects in apparantly healthy adults and children without acute illness or impaired renal handling of potasssium?

Summary Answer

High quality evidence shows that increased potassium intake reduces blood pressure in adults with hypertension and has no adverse effect on blood lipid concentrations, catecholamine concentrations, or renal function; higher potassium intake is also asociated with a 24% reduced risk of stroke (moderate and low quality evidence); evidence in children is sparse but also suggests a benefit on blood pressure with higher potassium intake.

What is Known and What this Paper Adds

Low potassium intkae has been associated with high blood pressure and risk of some cardiovascular diseases, but the evidence is not entirely consisten. This review provides the most comprehensive and up to date synthesis of literature on potassium intake and helth outcomes and concludes that increased potssium intake is beneficial for reducing blood pressure and risk of stroke.
