Scientists analyzed data on the amount of coffee and tea drinking in 365,682 people aged 50 to 74 years. The researchers followed the participants for 10-14 years. During this time, they suffered strokes and dementia.
The study authors found that drinking two to three cups of coffee or three to five cups of tea daily, and four to six cups of coffee and tea together, reduced the risk of stroke and dementia. People who drink two to three cups of coffee and two to three cups of tea a day have a 32% lower risk of stroke and 28% less risk of dementia, compared to people who do not drink tea and coffee.
Scientists believe it is due to the polyphenols and antioxidants found in drinks.
