OLDER adults with salty diets may have an increased risk of suffering a stroke, according to a US study of more than 2,000 people.
Though it is well known that as people's sodium intake rises, blood pressure is likely to increase as well, it is less clear whether a salty diet may mean a higher risk of strokes and heart attacks down the road.
But the researchers, whose findings were published in the journal Stroke, said that of the close to 2,700 older adults, mainly black and Hispanic New Yorkers, they studied, those who got well above the recommended sodium intake were nearly three times as likely to suffer a stroke over 10 years as people who met guidelines recommended by the American Heart Association.
"High sodium intake was prevalent and associated with an increased risk of stroke independent of vascular risk factors," wrote Hannah Gardener, a researcher at the University of Miami School of Medicine, who led the study.
The American Heart Association suggests people limit sodium intake to no more than 1,500 milligrams a day. The World Health Organization advises a 2,000 milligram limit.
