A new study from the University of Minnesota has found that home water softeners are sending a significant amount of salt into the state's lakes, streams and groundwater.
Bread and rolls are the No. 1 source of salt in the American diet, accounting for more than twice as much sodium as snacks like potato chips and pretzels.
Health experts are concerned that people will still be saying "pass the salt" this Thanksgiving, even when many prepared foods already are loaded with it.
