New York City’s Mayor has taken on smoking, trans fats and sugary drinks. Now, he says he’s winning the war on sodium.

Mayor Michael Bloomberg says 21 out of 24 companies have met their target goals to voluntarily reduce salt in prepackaged foods.

“Kraft reduced the amount of sodium in Kraft single American slices by 18 percent. Subway reduced sodium in two of its most popular sandwiches, the Subway Club and the Italian BMT which by accident happens to be my favorite.”

He challenged them three years ago when the city set voluntary guidelines for various restaurants and manufacturers to cut sodium levels by a quarter overall by 2014. More than 20,000 New Yorkers die each year from heart disease or stroke.

“Manufacturers aren’t stupid. They look and see what’s down the road. Down the road, we’re going to have to eat healthier or otherwise we’re going to go bankrupt with our health care costs.”

A city official says two participating companies are still working on meeting their targets. Hostess filed for bankruptcy.
