The Claim

A sodium-restricted diet limiting daily intake to approximately 1,500 mg, based on DASH principles, produces a modest but statistically significant reduction in systolic blood pressure by 2.3 mmHg and diastolic blood pressure by 1.2 mmHg over several weeks in hypertensive adults aged 30–70 in Pakistan.

In plain English

In hypertensive adults aged 30–70 in Pakistan, a diet limiting sodium to 1,500 mg per day based on DASH principles reduces systolic blood pressure by 2.3 mmHg and diastolic blood pressure by 1.2 mmHg over several weeks.

Why this might work

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 the lining of blood vessels work better, allowing them to relax more fully, which further lowers resistance to blood flow and reduces blood pressure.

  1. Study: ROLE OF SODIUM-RESTRICTED DIETARY APPROACHES TO CONTROL BLOOD PRESSURE IN PAKISTANI HYPERTENSIVE POPULATION

    This study found that when people with high blood pressure in Pakistan ate less salt—about 1,500 mg per day for several weeks—their blood pressure went down a little, but in a way that was real and not just by chance. This means cutting back on salt is a simple, cheap way to help manage high blood pressure along with other treatments.
