A Japanese study reveals that green tea significantly reduces the risk of deaths from several diseases. In an 11-year-old study that included 40,000 people there has been a 25% reduction in the risk of fatal cardiovascular disease. While some researchers contribute the decreased incidence to the green tea consumption, others say that Japanese diet alone is a great factor as well because it is healthy unlike the Western diet.

Eighty percent of people in Japan consume green tea and over 50% are consuming three or more cups a day. In the previously mentioned study, there has been a 16% reduction in risk of dying from any cause in people who consumed 5 or more cups of green tea a day. 26% reduction in risk of dying from cardiovascular disease was noticed. Women seemed to benefit more from green tea than men. There was no link between green tea consumption and death from cancer.

When the researchers examined the links between black or oolong tea consumption and reduction in risk of deaths from CVD, no significant links have been found. This indicates that the antioxidants specific to green tea could have the major role in cutting down the risks of diseases by reducing bad and increasing the good cholesterol as well as by preventing arterial plaque build up and enabling better functioning of the blood vessels.

Japan has already the lowest rates of cardiovascular disease in the world and many find that their diet plays the biggest role and not the green tea. More clinic trials are needed to determine if it is really the green tea that prevents deaths from heart disease.
