NEW YORK (AP) -- New York City could become the first city in the U.S. to require a warning label on high-sodium menu items at chain restaurants.
The city's Health Department tells The Associated Press it will propose Wednesday that all chain restaurants add a symbol resembling a salt shaker on menus next to food products that contain more than the recommended daily limit of 2,300 milligrams of sodium, equal to about 1 teaspoon of salt.
Sodium increases the risk of high blood pressure, which can lead to heart attack and stroke.
Studies have found that the vast majority of dietary salt comes from processed and restaurant foods.
Average sodium consumption is about 3,400 milligrams of sodium each day. Only about one in 10 Americans meets the 1 teaspoon guideline.
