Zhang Y, Yang H, Li S, et al. - In this study, separate or combined intake of coffee and tea was found to be linked with lower risk of stroke and dementia. A lower risk of poststroke dementia was noted in participants who drank coffee alone or in combination with tea.

• Coffee and tea have been shown to be implicated in the development of stroke and dementia in previous studies.

• From the UK Biobank, a total of 365,682 participants (50 to 74 years old) who reported their coffee and tea intake were analyzed to determine the links of coffee and tea separately and in combination with the risk of developing stroke and dementia.

• The lowest hazard ratio (HR) of incident stroke and dementia was reported in relation to coffee consumption 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.

• Intake of 2 to 3 cups of coffee with 2 to 3 cups of tea daily were linked with a 32% lower risk of stroke and a 28% lower risk of dementia.

• A daily intake level of 3 to 6 cups of coffee and tea was related to the lowest risk of incident poststroke dementia (HR, 0.52).
