The typical U.S. diet has 3400 mg of salt, while 1500 mg is the recommended amount. Sodium in the salt can raise blood pressure, increase the risk of heart attack and stroke, and weaken the kidneys.  While the salt shaker provides some of our salt, 75% of sodium in our food comes from canned and processed foods.  Instead of fast, frozen, canned, and processed foods,  go for fresh fruits and vegetables, whole grains and limited salt and fat for your health.
