Diet sodas may not be the best alternative to sugary drinks, according to a new study published in the American Heart Association's journal "Stroke" on Thursday.
The study suggests people drinking diet soda daily are almost three times as likely to develop stroke and dementia as those who consumed it weekly or less.
While the findings do not prove that diet drinks damage brains, they support other studies that show people who drink them frequently tend to have poorer health.
A second study published in "Alzheimers & Dementia," found that higher consumption of sugary beverages was associated with markers for pre-clinical Alzheimer’s disease.
The study also "found that those who reported consuming at least one artificially sweetened drink a day, compared to less than one a week, were 2.96 times as likely to have an ischemic stroke, caused by blood vessel blockage, and 2.89 times as likely to be diagnosed with dementia due to Alzheimer’s disease," said a summary from the AHA.
The American Beverage Association was quick to respond:
"Low-calorie sweeteners have been proven safe by worldwide government safety authorities as well as hundreds of scientific studies and there is nothing in this research that counters this well-established fact," it said in a statement.
