The agency wants to lower how much salt we consume over the next three years to an average of 2,750 milligrams per day. That's still above the recommended limit of 2,300 mg.

The Food and Drug Administration on Thursday laid out fresh goals to cut sodium levels in packaged and processed foods  by about 20%, after its prior efforts to address a growing epidemic of diet-related chronic diseases showed early signs of success.

The FDA in October 2021 had set guidelines to trim sodium levels in foods ranging from potato chips to hamburgers in a bid to prevent excessive intake of salt that can trigger high blood pressure, a major risk factor for heart disease and stroke.

The agency is now seeking voluntary curbs from packaged-food makers such as PepsiCo, Kraft Heinz and Campbell Soup. The companies did not immediately respond to requests for comment.
