Drinking Green Tea, Coffee May Help Lower Stroke Risk

Japanese survey also finds these beverages may ward off cardiovascular disease

FRIDAY, March 15 (HealthDay News) -- People who consume one or more cups of green tea or coffee per day have a lower risk of cardiovascular disease and stroke, according to a study published online March 14 in Stroke.

Yoshihiro Kokubo, M.D., Ph.D., from the National Cerebral and Cardiovascular Center in Osaka, Japan, and colleagues surveyed 82,369 Japanese who were free of cardiovascular disease and cancer regarding their consumption of green tea and coffee via a food-frequency questionnaire.

After a mean follow-up of 13 years, and after adjusting for age and sex, the researchers found that people who drank at least two cups of green tea per day had a lower risk of stroke compared to people who rarely drank tea (hazard ratio, 0.86). Greater tea consumption was also associated with a lower risk of cardiovascular disease and intracerebral hemorrhage. Similar results were observed for coffee, with a lower risk of stroke for people who drank at least one cup of coffee per day (hazard ratio, 0.80) and a lower risk of cardiovascular disease, cerebral infarction, and intracerebral hemorrhage.

"Higher green tea and coffee consumption were inversely associated with risk of cardiovascular disease and stroke in general population," the authors write.
