[Asia Economy Senior Reporter Jinsoo Lee] Research results suggest that drinking coffee or black tea may reduce the risk of stroke and dementia.

A research team from Tianjin Medical University in China reported in the weekly medical journal PLOS Medicine published on the 16th (local time) that people who drink 2-3 cups of coffee, 3-5 cups of black tea, or 4-6 cups of coffee and black tea combined daily have the lowest probability of suffering from stroke or dementia.

Stroke accounts for 10% of deaths worldwide. Moreover, dementia is one of the major global challenges. It is estimated that by 2050, 130 million people worldwide will suffer from dementia.

The research team from Tianjin Medical University tracked and investigated 365,682 men and women aged 50 to 74 in the UK over 15 years. The participants were part of the UK Biobank study. The UK Biobank is a project designed to collect genetic data from residents aged 40 and above across the UK.

The participants self-reported how much coffee and black tea they consumed daily. During the follow-up period, 5,079 participants developed dementia, and 10,053 experienced at least one stroke.

The results showed that people who drank 2-3 cups of coffee and 2-3 cups of black tea daily had a 32% lower risk of stroke compared to those who did not drink at all. The risk of developing dementia was 28% lower.

The researchers reported that whether drinking only coffee or alternating between coffee and black tea, it also appeared to reduce the risk of dementia following a stroke.

In the paper, the researchers wrote, "Whether drinking only coffee, only black tea, or alternating between the two, it is estimated to reduce the risk of stroke and dementia."

However, some experts unrelated to this study told the British daily The Guardian on the 16th that "more research is needed to fully understand the biological link between coffee, black tea, and stroke and dementia."
