Study: Americans eat too much salt

Nine out of 10 Americans eat too much salt every day, and many of them get more than twice the recommended daily amount, according to a new report from the CDC.

Researchers surveyed nearly 5,000 U.S. adults and found that they consumed a daily average of almost 3,500 milligrams of sodium. Current dietary guidelines say that Americans should get less than 2,300 milligrams of sodium each day.  However a government advisory panel recently urged officials to decrease the recommended daily sodium limit to 1,500 milligrams for all Americans.  Even people who steer clear of salty foods may not be avoiding excessive sodium. The report notes that many foods with a high sodium count, like breads, cookies and crackers, may not taste salty.
