Many restaurants in New York City will soon be required to place warning signs next to menu items with high salt content after the National Restaurant Association once again failed to convince a state court to overturn the regulation.

Last year, NYC's board of health required restaurants in the city with at least 15 locations nationwide to post warning labels next to menu items with at least 2,300 milligrams of sodium, which is the recommended daily allowance of sodium intake. NRA sued soon afterward, arguing the regulation was both costly and unfair because it targeted chain restaurants.

A lower court ruled against the association in February. NRA appealed the decision to the Appellate Division of state Supreme Court in Manhattan, but on Thursday the court upheld the lower court ruling. It also overturned a judge's order to prevent enforcement of the regulation until the case had worked its way through the courts, meaning chain restaurants will soon be required to comply.

NRA vowed to continue fighting the regulation in the courts.

"You have a radioactive symbol for an essential nutrient," NRA spokeswoman Christin Fernandez told the New York Times. "This is the first of its kind. It looks like a poison symbol."

The fine for noncompliance is only $200, but restaurants that don't participate risk losing their permits if they don't post warning labels. http://nyti.ms/1qOK2dl
