New York Seeks National Effort to Curb Salt Use

First New York City required restaurants to cut out trans fat. Then it made restaurant chains post calorie counts on their menus. Now it wants to protect people from another health scourge: salt.

On Monday, the Bloomberg administration plans to unveil a broad new health initiative aimed at encouraging food manufacturers and restaurant chains across the country to curtail the amount of salt in their products.

The plan, for which the city claims support from health agencies in other cities and states, sets a goal of reducing the amount of salt in packaged and restaurant food by 25 percent over the next five years.

Public health experts say that would reduce the incidence of high blood pressure and should help prevent some of the strokes and heart attacks associated with that condition. The plan is voluntary for food companies and involves no legislation. It allows companies to cut salt gradually over five years so the change is not so noticeable to consumers.

“We all consume way too much salt, and most of the salt we consume is in the food when we buy it,” said Dr. Thomas Farley, the city health commissioner, whose department is leading the effort. Eighty percent of the salt in Americans’ diets comes from packaged or restaurant food. Dr. Farley said reducing salt from those sources would save lives.

Since taking office, Mayor Michael R. Bloomberg, who just began his third term, has gained a reputation as an advocate for healthy living, initiating prominent campaigns against smoking and harmful trans fats. To combat obesity, he has campaigned for calorie labeling on restaurant menus and warned consumers about sugary soft drinks.

The city’s salt campaign is in some ways more ambitious and less certain of success than the ones it waged against smoking and obesity. For one thing, the changes it prescribes require cooperation on a national scale, city officials said, because major food companies cannot be expected to alter their products for just the New York market.

And removing salt from many products can be complicated. Salt plays many roles in food, enhancing flavor, preventing spoilage and improving shelf life. It helps bread to rise and brown.

The city’s campaign against salt resembles its push to cut trans fat from restaurant foods, which began with a call for voluntary compliance. When that did not work, the city passed a law to force restaurants to eliminate trans fat.

But city officials said it would be difficult to legislate sodium reduction.

“There’s not an easy regulatory fix,” said Geoffrey Cowley, an associate health commissioner. “You would have to micromanage so many targets for so many different products.”

He said officials hoped the campaign would work through public pressure. Companies that complied would benefit from good publicity.
