Artificially Sweetened Beverages, Stroke and Dementia Risk

An observational study in the Journal “ Stroke, A Journal of Cerebral Circulation” examined the question of whether there is an a relationship between consuming “ diet” beverages with artificial sweeteners and the development of a stroke or dementia using data from the Framingham Heart Study Offspring Cohort. They looked at 2888 individuals older than 45 years of age for the development of strokes and 1484 participants over age 60 for the development of dementia. They followed the group for ten years and were able to gauge their intake of artificially sweetened beverages from food questionnaires filled out at exams. After making adjustments for age, sex, education, caloric intake, diet quality, physical activity, and smoking they found that higher consumption of artificially sweetened beverages was associated with a higher risk of strokes and dementia. This was not seen in individuals drinking sugar sweetened beverages.

In a comment section, the author acknowledged that diabetic patients had a higher risk of stroke and dementia than the general public and they consumed more artificially sweetened beverages than others. While the study did not show cause and effect it does leave us wondering just how safe these diet drinks are?
