The Claim
A modest reduction in systolic blood pressure of 2–3 mmHg resulting from sodium restriction is associated with clinically meaningful reductions in population-level mortality from stroke and coronary heart disease, as supported by prior meta-analyses.
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.
Reducing sodium intake lowers systolic blood pressure by 2–3 mmHg, and this small change is linked to fewer deaths from stroke and coronary heart disease in the general population.

Eating less salt causes the kidneys to remove more water from the blood, which lowers the total amount of fluid in the bloodstream. This reduces the pressure pushing against artery walls. At the same time, less salt helps blood vessels relax by increasing a natural chemical that widens them, making it easier for blood to flow.
What the research says
1 studyEating less salt led to a small but real drop in blood pressure in people with high blood pressure, which is exactly how reducing salt is thought to prevent heart attacks and strokes across whole populations.
