According to research presented at the American Stroke Association’s International Stroke Conference 2011, diet soda drinkers have a much higher risk of vascular events compared to those who don’t drink soda,
The study, involving 2,564 people, found people who drank diet soda every day had a 61 percent higher risk of vascular events than those who reported no soda drinking.
In separate research using 2,657 participants also in the Manhattan study, scientists found that high salt intake, independent of the hypertension it causes, was linked to a dramatically increased risk of ischemic strokes (when a blood vessel blockage cuts off blood flow to the brain).
In the study, people who consumed more than 4,000 milligrams (mg) per day of sodium had more than double the risk of stroke compared to those consuming less than 1,500 mg per day.
“The take-home message is that high sodium intake is a risk factor for ischemic stroke among people with hypertension as well as among those without hypertension, underscoring the importance of limiting consumption of high sodium foods for stroke prevention,” Gardener said.
