A study has found that drinking a lot of coffee increases the risk of stroke. According to data published in the Journal of Stroke by a joint study between Galway University in Ireland and McMaster University in Canada, drinking more than four cups of coffee a day increases the risk of stroke by 37%.

 

Stroke is a condition in which brain cells are damaged and neurological symptoms manifest due to blockage or rupture of the brain arteries and carotid arteries that supply blood to the brain, leading to interruption of blood flow. During a stroke, 1.9 million nerve cells are lost per minute, and 120 million per hour.

South Korea is one of the countries experiencing a rapid increase in stroke patients. According to the National Disease Statistics, the number of stroke patients was 607,862 in 2020 and has been gradually increasing each year, reaching 653,409 last year. If previous research findings are accurate, the increased coffee consumption may have had a negative impact. Last year, the average annual coffee consumption per Korean adult was 405 cups, significantly exceeding the global average of 152 cups.

 

Researchers found that drinking tea instead of coffee reduces the risk of stroke by 18-20%. In particular, the incidence of stroke decreased by nearly 30% when drinking Earl Grey, English Breakfast (a blended black tea made from Assam and Ceylon tea), rather than green tea or herbal tea.

 

Martin O'Donnell, the chief physician at Galway University Hospital, stated, "You can reduce the risk of stroke through healthy lifestyle choices in daily diet and physical activity."

How many cups of coffee do you drink a day?

I was drinking three glasses, then I drank some alcohol.

Now I have reduced it to one glass.
