ATLANTA (AP) -- Bread and rolls are the No. 1 source of salt in the American diet, accounting for more than twice as much sodium as salty junk food like potato chips.

That surprising finding comes in a government report released Tuesday that includes a list of the top 10 sources of sodium. Salty snacks actually came in at the bottom of the list compiled by the Centers for Disease Control and Prevention.

"Potato chips, pretzels, and popcorn - which we think of as the saltiest foods in our diet - are only No. 10," said CDC Director Dr. Thomas Frieden.

Breads and rolls aren't really saltier than many of the other foods, but people tend to eat a lot of them, said Mary Cogswell, a CDC senior scientist who co-authored the report.
