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 new plan is said to be voluntary and involves no new legislation.  Does anyone believe it will stay that way?
