In plain English

Even if your blood pressure is normal, cutting back on salt still helps lower it a little—which could help prevent high blood pressure as you get older.

See the scientific wording

Sodium reduction lowers blood pressure in both hypertensive and normotensive adults, with significant effects even in those with baseline systolic blood pressure as low as 120 mm Hg, indicating broad population-wide benefit.

What the research says

1 study

  1. Study: Effect of dose and duration of reduction in dietary sodium on blood pressure levels: systematic review and meta-analysis of randomised trials

    This study found that eating less salt lowers blood pressure in everyone — even people whose blood pressure is already normal — so cutting back on salt helps the whole population, not just those with high blood pressure.
