Does sodium reduction reduce systolic and diastolic BP in participants of clinical trials?
Dietary sodium reduction linearly decreases both systolic and diastolic blood pressure, with greater absolute reductions seen in individuals with higher baseline blood pressure.
In this dose-response analysis of sodium reduction in clinical trials, we identified an approximately linear relationship between sodium intake and reduction in both systolic and diastolic BP across the entire range of dietary sodium exposure. Although this occurred independently of baseline BP, the effect of sodium reduction on level of BP was more pronounced in participants with a higher BP level.
