The Claim
Reducing sodium intake from 0.4 g/d to 7.6 g/d results in a nearly linear reduction in systolic blood pressure, with no threshold below which additional sodium reduction fails to further lower systolic blood pressure.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you eat less salt, your blood pressure goes down steadily — even at very low salt levels, cutting back more still helps lower it.
See the scientific wording
Sodium reduction lowers systolic blood pressure in a nearly linear fashion across the entire range of intake from 0.4 g/d to 7.6 g/d, with no evidence of a threshold below which further reduction provides no benefit.
What the research says
1 studyStudy: Blood Pressure Effects of Sodium Reduction
This study looked at what happens when people eat less salt, and found that the less salt they ate, the lower their blood pressure went — all the way down to very low levels, with no point where cutting more salt stopped helping.
