Did you know, a 20 oz. bottle of Coke-Cola contains 65 grams of sugar, the same as 5 Little Debbie swiss rolls? Many people opt for diet soda, thinking it is a healthier option.
However, gulping down an artificially sweetened beverage may not only be tied to health risks for your body, but also possibly your brain. This is based on the findings of a new study.
According to a study published by the American Heart Association’s journal Stroke on Thursday, artificially sweetened drinks, such as diet sodas, were tied to a higher risk of stroke and dementia.
“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.” wrote CNN’s Jacqueline Howard.
No connection was found between those health risks and other sugary beverages, such as sugar-sweetened sodas, fruit juice and fruit drinks.
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.”
The researchers analyzed how many sugary beverages and artificially sweetened soft drinks each person in the two different age groups drank, at different time points, between 1991 and 2001. Then, they compared that with how many people suffered stroke or dementia over the next 10 years.
Compared to never drinking artificially sweetened soft drinks, those who drank one a day were almost three times as likely to have an ischemic stroke, caused by blocked blood vessels, the researchers found.
They also found that those who drank one a day were nearly three times as likely to be diagnosed with dementia.
Those who drank one to six artificially sweetened beverages a week were 2.6 times as likely to experience an ischemic stroke but were no more likely to develop dementia, Pase said.
“So, it was not surprising to see that diet soda intake was associated with stroke and dementia. I was surprised that sugary beverage intake was not associated with either the risks of stroke or dementia because sugary beverages are known to be unhealthy,” Pase said.
“We know that sugary and artificially sweetened beverages are not great for us. This study adds strength to that, and also says they may not be great for your brain, specifically,” she said. “There are alternatives — things we can all do everyday to keep our brains and our bodies as healthy as we can as we age.” Alternatives such as regular cardiovascular exercise that elevates heart rate and increases blood flow and doing puzzles and games to activate and challenge the mind. These are recommendations from the Alzheimer’s Associations list of 10 lifestyle habits to reduce risk of cognitive decline.
