A new study conducted by Japanese scientists at the Tohoku University in Sendai confirms once again the multiple benefits of green tea upon human health. The team found that drinking five or more cups of green tea daily reduces the risk of death caused by various triggers, such as cardiovascular accidents and many others. However, they added that a regular consumption of green tea would not work against cancer symptoms which lead to death.
The general conclusion of this exhaustive and long-term study is that drinking green tea on a regular basis prolongs one's life span by cutting down his risks of severe diseases which could bring about death sooner or later. According to the researchers, the study is the amplest one ran until now, because it has involved and investigated the effects of green tea consumption on more than 40,000 Japanese people.
“Only four epidemiological studies in people have been conducted to date”. Those studies “included small sample sizes, and the results were inconsistent. However, our study includes far more participants - 40,350 - than the previous studies. I think our study would provide strong evidence regarding the benefits of drinking green tea in humans on cardiovascular disease,” pointed out lead researcher of the study Dr. Shinichi Kuriyama.
The research published in the Journal of the American Medical Association investigated the health of adults with ages ranging from 40 to 79, Northeastern Japan dwellers. The research began in 1994 and was completed recently. The team analyzed the causes of people's deaths which occurred during the 11 years follow-up study and compared these causes with the individuals' green tea consumption.
Results showed that adults who used to drink at least five cups of green tea daily were 16% less likely to experience premature death from all causes. Moreover, regular green tea drinkers had a 26% lower risk of cardiovascular death than their counterparts who did not consume the beverage. Green tea's beneficial effects upon women's health proved to be even stronger, as women who drank at least 5 cups of the beverage were 31% less likely to die from heart disease and stroke.
