Coffee and tea may reduce stroke risk according to recent studies. The data, released by the American Heart Association, revealed that people who drink coffee and tea may significantly reduce their risk or suffering a stroke.
Numerous people enjoy drinking coffee and tea, but most do not realize that their favorite drink may have positive effects on their health. Historically, the caffeine containing drinks were thought to be unhealthy.
As reported by NPR, the assumption that caffeine is harmful likely stemmed from prior research. Meir Stampfer of the Harvard School of Public Health suggests that earlier results may have been inaccurate as a large number of people who drink coffee also smoke. Testing results that revealed negative health consequences could have been caused by smoking, not the caffeine.
As technology progressed researchers have been able to isolate which negative health results were caused by smoking. Through new studies, researchers have identified evidence that caffeine, found in coffee and tea, can reduce stroke risk.
Green tea in particular was found to greatly reduce risk of stroke. Research revealed that those drinking green tea can reduce their risk of stroke by nearly 20 percent. Components found in green tea, called catechins, have been shown to regulate blood flow and blood pressure. Catachins, along with components found in caffeine, are thought to be responsible for the reduction in stroke risk.
The same results were found in coffee drinkers. The risk of stroke in those that regularly drink coffee was also found to be reduced by around 20 percent.
Dr, Rob van Dam of the Harvard Department of Nutrition has stated that otherwise healthy people can safely consume up to six cups of coffee per day without negative health risks. In an article at Harvard.edu van Dam suggests that using a paper filter when making coffee can further reduce any health risk as it will remove components that may cause increased LDL cholesterol.
Coffee and tea may reduce stroke risk, but doctors still recommend that pregnant women avoid consuming caffeine. Additionally, those with a history of heart disease or high blood pressure should discuss caffeine consumption with their doctor.
