New York restaurants to display symbol on high-salt dishes

New York City begins a new era in nutritional warnings this week, when chain restaurants will have to start putting a special symbol on high-salt dishes.

The first-of-its-kind rule takes effect on Tuesday. It will require a salt-shaker emblem on some sandwiches, salads and other menu items that top the recommended daily limit of 2,300mg – about a teaspoon – of sodium.
