The Claim

Low sodium intake is associated with increased heart rate and reduced augmentation index, suggesting altered vascular dynamics, but has no significant effect on pulse wave velocity, indicating no major change in arterial stiffness.

In plain English

Eating less salt might make your heart beat a little faster and change how your blood vessels respond, but it doesn’t seem to make your arteries stiffer.

What the research says

1 study

  1. Study: Dietary salt intake and cardiovascular outcomes: an umbrella review of meta-analyses and dose-response evidence

    This study found that eating less salt raises heart rate and makes blood vessels more flexible, but doesn’t make arteries stiffer — which is exactly what the claim says.
