Healthy Heart Reports

Salt Restriction And High Blood Pressure

Many doctors glibly prescribe a low salt diet to treat high blood pressure. A recent study from Finland shows that even with intense counseling and instruction, fewer than 20% are able to lower high blood pressure (1).

A diet rich in fruits and vegetables and low in fat is far more effective in lowering high blood pressure than a low-salt diet (2,3,4). Reducing salt intake a little does not lower high blood pressure (5,6) and reducing salt intake a lot can raise blood pressure even higher. Severe salt restriction causes your adrenal glands to produce large amounts of a hormone called aldosterone and your kidneys to produce large amounts of another hormone called angiotensin that constrict blood vessels and raise blood pressure (2,8,9). People on low-salt diets have a much higher death rate (10), and severe salt restriction can raise blood pressure (11) and blood cholesterol (12),/ and even cause heart attacks (13).

On the other hand, obese people are often sensitive to salt restriction because being overweight prevents your body from responding adequately to insulin and raises insulin levels. Since Insulin, itself, causes the body to retain salt, salt restriction raises blood levels of insulin which make a person hungry and fatter. Eating white flour and sugar makes your body much more sensitive to salt and restricting these food products decreases salt's ability to raise blood pressure (14). The 40% chance of lowering blood pressure with the most popular drugs is much lower than the 60% success rate of going on a low-fat diet and losing weight (15,16), so changing your lifestyle is far more effective in reducing high blood pressure than just taking drugs.
