Studies have found that women drinking coffee regularly can help prevent stroke

A new study by researchers in the United States and Spain has found that women who drink coffee regularly can reduce the risk of stroke, but for women who smoke a lot, drinking coffee can greatly reduce the effect of preventing stroke.

Researchers from Harvard Medical School in the United States and the Autonomous University of Madrid in Spain said in a press release on the 18th that they reached the above conclusion by analyzing the relevant data of more than 83000 adult women. The women took part in a health medical survey between 1980 and 2004, and before the survey began, they had no history of stroke, heart disease, diabetes or cancer. But in the 24 years of the survey, nearly 2300 of them had strokes.

The researchers said that by analyzing the relationship between the risk of stroke and coffee drinking in the women surveyed, they found that coffee had different effects on different people. For women who have never smoked or have smoked but have since quit, drinking more than four cups of coffee a day can reduce their risk of stroke by 43%. But for women who smoked, although they drank the same amount of coffee every day, the risk of stroke decreased by only 3%, suggesting that smoking greatly offset the stroke prevention effect of drinking coffee.

In addition, the researchers found that how much coffee they drank each day also had an effect on the risk of stroke. Women who drank about three cups of coffee a day had a 19% lower risk of stroke than those who drank less than one cup of coffee a month.

The findings will be published in the March issue of the journal Circulation.
