Sodium is a mineral that the body uses to regulate blood pressure.
Sodium also helps muscles and nerves work properly. The National Research Council of the National Academy of Sciences recommends an approximate daily range of 1,100 to 3,300 milligrams of sodium for adults. The American Heart Association recommends that for every 1,000 calories of food consumed, the sodium intake should be 1,000 milligrams and should not exceed the 3,000 milligram limit. The average intake in the United States is between 4,000 and 5,000 milligrams of sodium per day. Fast food also generally contains a lot of sodium.
