Should more states/countries force food manufacturers to reduce the amount of sodium in their processed, packaged food?

New York City health officials have battled trans fat and high-calorie fast food. Now, they're taking on salt. The health department planned to release draft guidelines suggesting the maximum amount of salt that should be in a wide variety of manufactured and packaged foods. New York City's program is modeled in part after a similar initiative in the United Kingdom that has been underway since 2003.
