Does iced green tea have the same health benefits as freshly brewed green tea?
Green Tea AnswerDear Sandra, If you brew your green tea yourself and then ice it, it should have the same health benefits as freshly brewed hot green tea. But don’t let the tea stand at room temperature for more than a few minutes before refrigerating it, as its catechin content can start to diminish.If your iced tea comes from bottled green tea, however, chances are you are getting far fewer catechins than you would if you drank freshly brewed green tea. The health-promoting catechins in green tea are sensitive to heat and oxygen, so they’re easily destroyed during the processing, transporting and storing of bottled tea. Given that, it’s not surprising that researchers at Oregon State University found that the polyphenols and antioxidant activity in some bottled tea products were 10 to 100 times lower than those found in brewed tea!
