Green tea for healthy life13th September 2006
Researchers say that drinking green tea can reduce the risk of early death from heart disease by up to a quarter.
The researchers, from the Tohoku University School of Public Policy, in Sendai, Japan, studied more than 40,000 people. Their results suggested that drinking five or more cups a day can also decrease deaths from other causes such as strokes. However, they found no link between green tea consumption and a reduced risk of death from cancer.
The study, published in the Journal of the American Medical Association started in 1994, and included 40,530 adults aged 40 to 79 in north-eastern Japan. Eighty per cent of the population in this region drink green tea regularly, with more than half consuming three or more cups a day.
Researchers found that people who consumed five or more cups had a 26 per cent lower risk of fatal heart disease, and 16 per cent lower risk of death from any cause than those who consumed less than one cup of green tea a day, with women benefiting most.
Polyphenols, the chemicals in green tea known to have strong antioxidant properties, have widely studied as possible preventive agents for heart disease and cancer. However, the researchers in this study found no significant association between green tea consumption and death from cancer.
