About nine of every 10 Americans eat more salt than is recommended, and Public Enemy No. 1 is bread — not junk food, the federal Centers for Disease Control and Prevention said Tuesday.

Salt, or sodium chloride, is a sneaky ingredient, ending up in many food products that don't sport the distinctive tang of a potato chip. But just because the sodium intake per slice of bread may be lower than a serving of potato chips doesn't mean that the salt isn't piling up. Americans love bread.

According to the CDC, the average person consumes about 3,300 milligrams of sodium per day, well above the current daily guideline of about 2,300 milligrams, or about a teaspoon of salt.

The salt poured at the table is rarely the culprit, because eaters can easily control intake. It is the hidden salt found in processed foods that help push Americans over the limits.

Just 10 types of food are responsible for more than 40 percent of people's sodium intake, the CDC noted. Leading the pack are bread and rolls, followed by luncheon meat such as deli ham or turkey. Pizza, poultry, soups, sandwiches, cheese, pasta dishes and meat dishes round out the list.

Snacks such as potato chips, pretzels and popcorn are at the bottom of the 10-worst list.
