Topic Overview

Eating a lot of sodium is linked with high blood pressure and problems in the heart, kidneys, and blood vessels.

Reducing sodium in the diet can prevent high blood pressure in those at risk for the disease and can help control high blood pressure. Limiting sodium is part of a heart-healthy eating plan that can help prevent heart disease and stroke.

Most people with high blood pressure shouldn't eat more than 2,000 milligrams (mg) of sodium a day.footnote 1
