Stroke - acute impairment of cerebral circulation, noticeably "rejuvenated" for the last decade. This medical emergency can be averted by having a few glasses of black or green tea a day. This statement was made by a group of American scientists from the University of California, studied nine researches on the subject. http://www.sciencedaily.com/releases/2009/02/090223091806.htm
In recent years, every twelve months, around the world more than six million people are diagnosed with a stroke. In peacetime, stroke causes the death of every third adult person, which means that is more frequent cause of death than a car accidents. Thus, every two out of ten cases of stroke happen to people under the age of fifty. There are very few ways to reduce the risk of stroke. According to lead author of study Lenore Arab, a professor of medicine, by the time a stroke victim receives medical care, it’s nearly too late to impede the damage. Another research found that 25 percent of people who had a stroke died within one year.
American scientists have collected and conducted nine large-scale studies on the relationship between regular consumption of green and black tea, and the risk of stroke. It appears that tea may be the prevention from this disease. The survey covered nearly 195,000 individuals of different sex, age, social status, and so on. This group of people in a certain period of time had 4,378 cases of stroke.
As the researchers found, people that regularly drink green or black tea two to three cups which is about three hundred milliliters of tea per day, the risk of stroke for them is reduced by 21%, compared to people who do not drink tea at all, or drink one cup a day or less.
The scientists suggest that the whole matter in the substances contained in tea, and plan soon to conduct a series of clinical trials to confirm the findings.
