Low salt diet
Low salt diet

Background

Adults need less than 2,400 mg of sodium per day, according to the National Heart, Lung, and Blood Institute (NHLBI). Most Americans eat about four or five times the amount they need. Table salt is just one source of this mineral in the American diet. Almost every non-fresh food purchased at the grocery store contains added amounts of sodium, which are disproportionate to the body's level of need.

Sodium is necessary for a proper fluid balance in the body and the healthy functioning of muscles. However, most Americans consume significantly more of this mineral than is necessary, or even healthy.

Salting food or purchasing high sodium products is not necessary to receive adequate amounts of this mineral. Americans receive enough sodium in their diets by eating a healthy balance of fruits, vegetables, grains, protein, and milk without any additives.

People use this for...

A low salt diet is used in people with high blood pressure, congestive heart failure, cirrhosis, or kidney disease.

Pregnancy And Lactation: There's no reason to expect safety issues with the low salt diet in pregnancy and lactation.

INSUFFICIENT RELIABLE EVIDENCE TO RATE

Coronary heart disease. Some research suggests that following a low sodium diet may reduce the risk of coronary heart disease. More evidence is needed to rate the low salt diet for this use.

Natural Medicines rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

    Mechanism of action

    The NIH places a strong emphasis on the reduction of salt intake as a means of preventing, as well as recovering from, coronary heart disease. Decreasing salt in the diet of people with coronary heart disease will theoretically help reduce the risk of high blood pressure and edema.

    The NHLBI notes that sodium intake must be at or below 1,500 mg per day in order to fully benefit from a low sodium diet.
