The Claim
Reducing dietary sodium intake from 7.6 g/d to 1.5 g/d causes a linear reduction in systolic blood pressure by approximately 15 mm Hg and diastolic blood pressure by approximately 10 mm Hg in adults, with the greatest effect observed in individuals with hypertension.
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 cut down how much salt you eat from a lot to very little, your blood pressure will go down—by about 15 points for the top number and 10 points for the bottom number—and this works best if you already have high blood pressure.

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 lowering salt intake lowers blood pressure — especially in people who already have high blood pressure — just like the claim says.
