Sodium is needed for the body to work properly. The body uses sodium to control blood pressure and blood volume. Sodium is also needed for muscles and nerves to work properly. Too much sodium has the potential to cause or exacerbate high blood pressure in some people or a build-up of fluid in people with congestive heart failure, cirrhosis, or kidney disease.
Plant: Most plants, particularly beets and celery.
NOTE: Sodium occurs naturally in most foods. The most common form of sodium is sodium chloride, which is table salt. Drinking water may also contain sodium, although the amount varies depending on the source.
« It is recommended that healthy adults limit their sodium intake to 2,300 mg per day. Adults with high blood pressure should have no more than 1,500 mg per day. Those with congestive heart failure, liver cirrhosis, and kidney disease may need much lower amounts.
