Too much sodium (salt) in our diet is the subject of a new study by the CDC, the Centers for Disease Control and Prevention.

And what items in our diet do you suppose brings us the most sodium? Bread and rolls, the study found. Not because they are so heavy in salt, but because we eat so much of them.

Two-thirds of our sodium intake is added to foods we purchase at the grocery or the restaurant. Meals prepared at home can reduce the overload of sodium, which averages 3,300 miligrams per day per person, 1,000 more than the health folks recommend.

The other sources of sodium in the CDC’s study were cold cuts and cured meats, pizza, poultry, soups, sandwiches and burgers, cheese, pasta dishes, meat mixed dishes and snacks — in that order.

The study is reported in a Tufts University health letter.
