Surprising Findings
Low sodium intake increased heart rate and improved vascular elasticity — but didn’t reduce arterial stiffness.
Most assume low salt = more flexible arteries. But this shows the body compensates differently — faster heartbeat and better blood flow dynamics without changing artery rigidity.
Practical Takeaways
Cut your daily salt by 1 gram — roughly 1/4 teaspoon — by skipping the salt shaker, choosing low-sodium soy sauce, and avoiding processed snacks.

Eating more salt every day is linked to a higher chance of heart problems and strokes—every extra gram of salt per day raises your risk by a little bit, according to a big review of many studies.
