"But the science is settled!" department:
An unusual medical brawl erupted on Tuesday when the influential Institute of Medicine issued a report questioning the basis of years of advice for Americans to cut their salt intake in half.
The Institute, which advises the federal government on medical issues, concluded that the studies have answered the question poorly. A panel of experts looked at studies showing the medical effects of eating too much salt, as well as at studies that have been used to suggest that some people may suffer form eating too little salt.
Haven't they figured out yet that obsessing about what you put into your mouth does far more long-term harm than anything you eat too much or too little of?
