People who regularly drank artificially sweetened
beverages are also more likely to suffer a stroke, but the full-fat equivalent is not
associated with a greater risk of either condition. Researchers have warned, however, not to treat
sugary drinks as a healthy option, saying there may be an as yet undetected link between
full-fat drinks, dementia and stroke. The nature of the study means they cannot
prove a causal link between diet drinks and dementia, but previous research has shown
that artificial sweeteners can damage blood vessels.
