How it works

Eating less salt makes the kidneys get rid of extra water, which lowers the pressure in the blood vessels. It also helps the blood vessels open up more by increasing a natural relaxing chemical, which further reduces pressure.

Most probable mechanism

In Simple Terms

Eating less salt causes the kidneys to remove extra water from the blood, which lowers the total amount of fluid in the bloodstream. This reduces the pressure on artery walls. At the same time, less salt helps blood vessels relax by increasing a natural chemical that opens them up, further lowering pressure.

Causal chain
1

Reduced dietary sodium intake decreases renal sodium reabsorption, leading to osmotic loss of water and decreased plasma volume.

Decreased plasma volume reduces cardiac output and arterial pressure.

Lower sodium levels reduce oxidative stress in vascular endothelium, increasing nitric oxide bioavailability.

Increased nitric oxide bioavailability causes vasodilation, reducing peripheral vascular resistance.

Similar Assertions

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.

Following a specific heart-healthy diet called DASH and limiting salt intake to 2,000 mg a day for three months can cut the chances of developing metabolic syndrome by about 71% in adults with slightly high blood pressure who aren't taking medication. This approach works much better than just getting standard advice on how to eat for blood pressure.

People with very high blood pressure at the start of a low-sodium DASH diet see a bigger drop in their numbers compared to those with milder high blood pressure. This means the diet works especially well for severe cases and might help some patients need fewer blood pressure medications.

If you have high blood pressure and eat a lot of salt, switching to the DASH diet can lower your blood pressure by up to 10.6 points—but if you’re already eating very little salt, the diet might not help as much. So, it works best when you’re still eating salty foods.

Eating less salt and more potassium together lowers blood pressure better than just cutting salt or just adding potassium alone—and that’s why the DASH diet works so well.
