Simulating the impact of sodium reduction from packaged foods on population sodium intake in US adults and children.

The study demonstrated that if Na reduction shifted the top-ten packaged food group sources of dietary Na intake from the median to 25th percentile, population Na intake would be reduced by 9 % in US adults and children. These findings will help inform the US government's Na reduction targets, as well as policy makers' understanding of differences in intake of critical sub-populations in the USA.
