Drinking Coffee or Tea May Be Linked With Lower Risk of Stroke & Dementia: New, Largest Study
- The Guardian, Nov. 16, 2021. Tea and coffee may be linked to lower risk of stroke and dementia- study.
Research looking at 365,000 people aged 50-74 finds moderate consumption could have health benefits.
Drinking coffee or tea may be linked with a lower risk of stroke and dementia, according to the largest study of its kind. Strokes cause 10% of deaths globally, while dementia is one of the world’s biggest health challenges – 130 million are expected to be living with it by 2050.
In the research, 365,000 people aged between 50 and 74 were followed for more than a decade. At the start the participants, who were involved in the UK Biobank study, self-reported how much coffee and tea they drank. Over the research period, 5,079 of them developed dementia and 10,053 went on to have at least one stroke.
Researchers found that people who drank two to three cups of coffee or three to five cups of tea a day, or a combination of four to six cups of coffee and tea, had the lowest risk of stroke or dementia. Those who drank two to three cups of coffee and two to three cups of tea daily had a 32% lower risk of stroke. These people had a 28% lower risk of dementia compared with those who did not drink tea or coffee.
The research, by Yuan Zhang and colleagues from Tianjin Medical University, China, suggests drinking coffee alone or in combination with tea is also linked with lower risk of post-stroke dementia. Writing in the journal Plos Medicine, the authors said: “Our findings suggested that moderate consumption of coffee and tea separately or in combination were associated with lower risk of stroke and dementia.”
However, the scientists cautioned that the UK Biobank reflects a relatively healthy sample relative to the general population, which could restrict the ability to generalise these associations...
