MORE INFO:

Make no mistake about it: salt is essential for human health. The average adult’s body contains 250 grams (g) of sodium — less than 9 ounces, or about the amount in three or four saltshakers. Distributed throughout the body, salt is especially plentiful in body fluids ranging from blood, sweat, and tears to semen and urine.
