What is the level of antioxidants found in tea?

Answer 1

The antioxidant content of various types of tea has been well studied. An analysis on 20 common brands of tea has shown that they contain widely varying amounts of antioxidants, which are known to help fight off cancer and heart disease among other illnesses.

The following teas were brewed for 3 minutes each and the antioxidant level is shown below:
Brand of Tea Catechin content (in milligrams)
Celestial Seasonings Green Tea 217
Lipton Green Tea 201
Bigelow Darjeeling Blend (black tea) 164
Uncle Lee's Green Tea 157
Stash Premium Green Tea Decaf 53
Twinings Earl Grey Black Tea 46
Bigelow Constant Comment (black tea) 38
Bigelow Constant Comment Decaf 10
Lipton Lemon Iced Tea 0
Snapple Peach Iced Tea 0

The overwhelming of all tea consumed in the U.S. is black tea. The processing method of tea may account for some of the differences in antioxidant levels. Green tea is commonly thought to have more antioxidants than black tea. This was often, but not always the case. Most scientists that have really studied this have found that the number of antioxidants in black tea is actually higher than what is found in green tea.

Answer 2
