NEW YORK (AP) Chain restaurants across New York City may soon be compelled to add a new item to their menus: a salt-warning symbol.

The city's Board of Health is set to vote Wednesday on a groundbreaking rule that would slap a black-and-white salt-shaker emblem on chain-eatery dishes with more than the recommended daily limit of 2,300 milligrams of sodium. That's about a teaspoon.

It could include foods ranging from BLT sandwiches to fried chicken to even some salads.

City health officials say they're just trying to provide information. Experts say salt is too prevalent in most Americans' diets, raising their risk of high blood pressure and potential heart attacks and strokes.

Public health advocates applaud the proposal. Salt producers and restaurateurs call it a misguided step toward an onslaught of confusing warnings.
