Perhaps it's time to cut back on the salt a bit. As far back as the 1960s, physicians linked salt to high blood pressure, a major risk factor for heart disease and stroke. Today, more than 65 million Americans have hypertension -- repeatedly high blood pressure -- according to the National Heart, Lung and Blood Institute, and 59 million more have pre-hypertension, a level higher than normal that can also lead to health problems.
