Green Tea and Antioxidants
Tea is brewed from the dried leaves of the Camellia sinensis bush and can be categorized into four types, depending on the level of oxidation: white (unoxidized buds), green (unoxidized leaves), oolong (partially oxidized leaves), and black (oxidized leaves). The health benefits of tea stem from the antioxidants it contains, primarily flavonoids, also known as catechins.
All teas contain antioxidants, though green and black teas contain the highest amounts of flavonoids. Other factors that determine the antioxidant levels of tea include tea quality, origin of growth, brewing method, and brewing time. The antioxidant levels in dry tea leaves are much higher than those in brewed tea because the tea leaves are discarded after the brewing process.
