Effect of increased potassium intake on cardiovascular risk factors and disease: systematic review and meta-analyses
Salt seems to get the most press, but potassium is an important player in the prevention of vascular disease. This systematic review of 22 RCTs and 11 cohort studies shows that systolic blood pressure was reduced by 7.16 (1.91 to 12.41) mm Hg when the potassium intake was 90-120 mmol/day, without any dose response. Furthermore, there was a 24% lower risk of stroke. The results suggest that patients without impaired renal excretion of potassium would potentially see the most benefit with respect to hypertension and stroke prevention with increased potassium intake.
