According to a recent Morbidity and Mortality Weekly Report (MMWR), more than half of Americans now report taking action towards reducing the amount of sodium in their diets. This is the first study to report state-level estimates of sodium intake behavior among the general population.

Excess sodium intake is a major risk factor for hypertension, and subsequently, heart disease and stroke. During 2011–2012, the average daily sodium intake among U.S. adults was estimated to be 3,592mg, significantly higher than the recommended target of 2,300mg. More than three quarters of sodium in the American diet is estimated to come from processed and restaurant food. Sodium is also found in products that some may not consider “salty,” such as bread, pasta and cereal.
