Also, there are some hints, albeit from studies with serious flaws, that eating the lowest levels might actually harm certain people -- those who are being aggressively treated for serious heart failure, the report added.
The prestigious group, which advises the government about health, urged more and better research to settle the best target range.
"We're not saying we shouldn't be lowering excessive salt intake," said Dr. Brian Strom of the University of Pennsylvania, who led the IOM committee. But below 2,300 mg a day, "there is simply a lack of data that shows it is beneficial."
