Represented by Public Citizen, CSPI filed suit yesterday in federal court in DC to compel action by FDA on CSPI's citizen petition to reduce the alarming amount of salt to which U.S. consumers are exposed. The petition has been pending for 10 years, and FDA's foot-dragging dates back far longer, explains CSPI in its press release.
As for the scope of the problem and the risks, CSPI says:
[T]he FDA’s failure to reduce the sodium in packaged and other foods is contributing to tens of thousands of premature deaths annually due to stroke, heart disease, and other health problems. The average American consumes about 3,650 milligrams of sodium per day, far in excess of the 2,300 milligram limit recommended by federal dietary guidelines, or the 1,500 milligram limit recommended for certain subgroups, including children, people over 50, African Americans, and people with hypertension, kidney disease, or diabetes.
