NEW YORK CITY — Beginning today, New York City chain restaurants have to add a special salt-shaker symbol on menu items that have more than the recommended daily limit of sodium (2,300 milligrams, which is around a teaspoon), Business Insider reports.

“With the high sodium warning label, New Yorkers will have easily accessible information that can affect their health,” said Dr. Mary Bassett, the city’s health commissioner, back in September when the Board of Health passed the requirement.

However, the restaurant industry has lashed back, accusing the city of zeroing in on only one ingredient. “Every one of these cumbersome new laws makes it tougher and tougher for restaurants to find success,” said Melissa Fleischut, president of the New York State Restaurant Association.

The new salt warnings will need to be placed next to around 10% of menu items at restaurant chains with 15 or more outlets in the United States. City officials claim that applies to about a third of the city’s restaurants. New York has given restaurants a grace period to comply, with fines not collected until March 1.

New York City has also banned trans fats from restaurants and pushed chains to post calorie counts next to menu items. The locality also attempted to restrict the size of sugared beverages.
