Zhang Y, Yang H, Li S, et al. - Lower risk of stroke and dementia was observed in persons who consumed coffee and tea separately or in combination. A lower risk of poststroke dementia was found in those who drank coffee alone or in combination with tea.

• From the UK Biobank, a total of 365,682 participants (50 to 74 years old) who reported their coffee and tea intake were included.

• The lowest hazard ratio of incident stroke and dementia was obtained in relation to coffee intake of 2 to 3 cups/d or tea intake of 3 to 5 cups/d or their combination intake of 4 to 6 cups/d.

• A 32% lower risk of stroke and a 28% lower risk of dementia was observed in relation to drinking 2 to 3 cups of coffee with 2 to 3 cups of tea daily.

• Lower risk of poststroke dementia was reported in relation to consumption of coffee alone or in combination with tea.

• Overall, a potential beneficial link between coffee and tea intake and risk of stroke, dementia, and poststroke dementia was highlighted but causality cannot be inferred.
