Consuming a can a day of low- or no-sugar soft drink is associated with a much higher risk of having a stroke or developing dementia, researchers claim.

Their findings have prompted renewed questions about whether drinks flavoured with artificial sweeteners can increase the risk of serious illness, as heavily sugared drinks have already been shown to do.

“Drinking at least one artificially sweetened beverage daily was associated with almost three times the risk of developing stroke or dementia compared to those who drank artificially sweetened beverages less than once a week,” according to the American researchers who carried out a study published in Stroke, the journal of the American Heart Association.

“After adjustments for age, sex, education (for analysis of dementia), calorific intake, diet quality, physical activity and smoking, higher recent and higher cumulative intake of artificially sweetened soft drinks were associated with an increased risk of ischaemic stroke, all-cause dementia and Alzheimer’s disease dementia,” the co-authors write.
