Gulping down an artificially sweetened beverage not only may be associated with health risks for your body, but also possibly your brain, a new study suggests.
Artificially sweetened drinks, such as diet sodas, were tied to a higher risk of stroke and dementia in the study, which published in the American Heart Association’s journal Stroke on Thursday.
The study sheds light only on an association, as the researchers were unable to determine an actual cause-and-effect relationship between sipping artificially sweetened drinks and an increased risk for stroke and dementia. Therefore, some experts caution that the findings should be interpreted carefully.
No connection was found between those health risks and other sugary beverages, such as sugar-sweetened sodas, fruit juice and fruit drinks.
“We have little data on the health effects of diet drinks and this is problematic because diet drinks are popular amongst the general population,” said Matthew Pase, a senior research fellow in the department of neurology at Boston University School of Medicine and lead author of the new study.
“More research is needed to study the health effects of diet drinks so that consumers can make informed choices concerning their health,” he said.
The new study involved data on 2,888 adults older than 45 and 1,484 adults older than 60 from the town of Framingham, Massachusetts. The data came from the Framingham Heart Study, a project of the National Heart, Lung, and Blood Institute and Boston University.
In the older-than-45 group, the researchers measured for stroke and in the older-than-60 group, they measured for dementia.
“The sample sizes are different because we studied people of different ages,” Pase said. “Dementia is rare in people under the age of 60 and so we focused only on those aged over 60 years for dementia. Similarly, stroke is rare in people aged under 45 and so we focused on people older than age 45 for stroke.”
