Recommended daily sodium levels too low, says a new study. (Fotolia)


 

Go ahead and eat those salt-and-vinegar chips, because the sodium levels recommended by experts are actually too low, according to a new Danish study.

The Centers for Disease Control (CDC) says healthy people under 50 should consume no more than 2,300 mg of sodium per day, and those over 50 no more than 1,500 mg per day.

But a meta-analysis of 25 separate studies, involving more than a quarter of a million people, found that a range of 2,645-4,945 mg per day is actually healthier.

Diets higher or lower than that range were associated with increased mortality, according to the analysis led by Copenhagen University Hospital.

"Our results are in line with the (Institute of Medicine's) concern that lower levels could produce harm, and they provide a concrete basis for revising the recommended range in the best interest of public health," lead author Dr. Niels Graudal said in a press release.

Canadians eat about 3,400 mg of sodium per day, according to Health Canada, whose guidelines follow the CDC recommendations.

The study was published in the American Journal of Hypertension.
