Antioxidant levels in Tea
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. Many studies conducted have found that the common known antioxidants found in tea are polyphenols and catechins. Tests were conducted on a variety of green and black teas to measure the catechin content. The teas were brewed for 3 minutes each and the results are as follows:
Anti-Aging Perspective:80% 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 in the new study. 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. Due to the caffeine content (about 50 mg for tea vs. 100 mg for coffee per cup), there are simply better ways to get antioxidants other than from drinking tea. From an anti-aging perspective, pure filtered water is still the number one beverage.
