Effect of longer term modest salt reduction on blood pressure: Cochrane systematic review and meta-analysis of randomised trials
This Cochrane study supports the notion that our society needs to reduce total salt intake.. Thirty-four trials and over 3000 participants were included in this meta-analysis. The results are impressive: the mean change in urinary sodium was −75 mmol/24 h with an associated mean change in systolic blood pressure of −4.18 mm Hg (95% confidence interval −5.18 to −3.18, I2=75%) and −2.06 mm Hg (−2.67 to −1.45, I2=68%) for diastolic blood pressure.
