Drinking Coffee and Tea May Reduce Risk of Stroke and Dementia
Coffee and tea are among the most widely consumed beverages worldwide. A new study has found that consuming coffee and tea may help reduce the risk of stroke and dementia.
Participants in the study included 365,682 adults with an average age of 62 who are part of the UK Biobank. Participants self-reported their consumption of tea and coffee at the beginning of the study. They were followed for an average of 11.4 years. All incidences of stroke and dementia were recorded.
Participants who drank 2 to 3 cups of coffee, 3 to 5 cups of tea, or 4 to 6 cups of both coffee and tea daily were found to have a 32% reduced risk of stroke compared to those who did not drink tea or coffee. They were also found to have a 28% reduced risk of dementia. The researchers believe these findings may be due to the antioxidant and polyphenolic content of coffee and tea.
The study was conducted by researchers from Tianjin Medical University. It was published online ahead of print on November 9, 2021 in the journal PLOS Medicine.
