Sodium keeps your heart beating in a strong, steady rhythm. It also helps balance the functioning of all your muscles and nerves. Sodium is the major regulator of your body's water balance and keeps the other vital minerals in proper concentration in your tissues and blood.
WARNING: Sodium has one of the strongest links to high blood pressure of anything we eat, although only one American in five has the genetic hypersensitivity to sodium that makes it raise our blood pressure to dangerous levels. Too much sodium can produce other damaging effects, however, in body systems like your kidneys and your heart.
Optimal Level: You can't help but get enough sodium without even trying, so make an effort to keep your daily intake as low as possible.
