Green tea is known in Asia for centuries. Unlike black teas, resulting from the fermentation of tea leaves are green teas unfermented. This leaves more of the Polyphenols in tea.
Black tea has 3 to 10% Polyphenols, green tea as much as 30 to 40%.Due to the high content of green tea Polyphenols attach a series of beneficial effects on health, from normalizing blood pressure to reduce the chance of developing cancer. Since all the positive effects of green tea have not been approved yet, only subsequent research will confirm if green tea Polyphenols actually help in the fight against various diseases.
