New York City will be the first city to require chain restaurants to identify highly-salted dishes with a special symbol, starting this week. CBS News  reports that, starting Tuesday, a salt-shaker emblem will be required to be placed next to menu items that contain over 2,300 milligrams of sodium.

Experts say Americans consume too much sodium, which puts many at risk for high blood pressure and heart issues. On average, Americans consume approximately 3,400 milligrams of salt daily. Health advocates are in favor of the new emblem, in hopes that identifying the high-sodium dishes will make consumers more aware of the amount of salt they are ordering.

A majority of sodium consumed by Americans comes from prepared foods, rather than directly from a salt shaker. Because of this, most people are unaware of how much salt they actually consume.

Some salt producers, however, say New York City is acting on information that may not be entirely accurate. A study held internationally last year,with over 100,000 participants found that the amount of salt consumed by the average person is fine for one’s health.

Restaurants have their own concerns over the new rules, as federal regulators are in the process of determining new sodium intake guidelines, nationwide. Some feel that the regulations make the success of a restaurant more difficult.

The new regulations are expected to apply to around 10 percent of menu items at New York City locations of national chains, with 15 or more outlets. These eateries make up roughly one-third of New York City’s restaurant business.

The regulations will not be enforced, or subject to fines until March 1, despite going into effect Tuesday.
