A new study suggests reducing average daily sodium consumption could reduce annual health care costs (attributable to cardiovascular complications) by billions:

By reducing average daily intake to 2,300 mg/day, $18 billion could be saved in Health Care per year.

By reducing average daily intake to 1,500 mg/day, $26 billion could be saved in Health Care per year.

*2,300 mg is the current recommended daily limit.
