Green Tea for Cardiovascular Health

Green or black tea may produce improvements in heart health according to a new study.
Salada has 2 new blends available sold as antioxident supplements. One claims to have "Green" antioxidents and has a vaguely citrus flavor. The other has "Red" antioxidents and has a delightful strawberry-orange flavor that needs no sweetener. What's the difference between green and black teas? (From the Real Age website)

Black, oolong, and green teas are made from leaves of the Camellia sinensis plant. The difference between green and black tea is the level of oxidation the tea leaves experience during processing. The longer tea leaves experience oxidation, the darker they become. Research suggests oxidation levels probably have little influence over the amount of heart-healthy flavonoids different teas contain, although there may be some variation. A recent animal study suggests both green and black tea may produce similar improvements in blood vessel health. According to the researchers, the average 150-pound person would have to drink two 5-ounce cups of green or black tea daily to get heart-health benefits similar to those achieved in the animal study.
