The research backing these claims appeared in the journal Nutrition Bulletin. A 12-week study of 87 volunteers, financed by the industry backed Tea Advisory Panel (TAP), showed three cups of tea a day led to a significant improvement in various cardiovascular risk factors.
Researchers found two or more cups protect against type 2 diabetes. Results were similar, with or without milk.
The benefits are attributed to the 150- to 200-mg of flavonoids in tea are equivalent to five portions of vegetables and may be the best delivery of antioxidants.
Nutritionist Dr. Carrie Ruxton, who co-authored the review reports tea’s active ingredients control inflammation, reduce excess blood clotting, promote blood vessel function and reduce clogging in arteries.
“There is far more to the nation's favorite drink than we realize,” reports Ruxton. “With its antioxidant flavonoids, black tea packs a powerful punch with many health benefits particularly for the heart. And recent studies show that the flavonoids work their magic whether or not we choose to add milk.”
“Chronic conditions such as heart disease, stroke and diabetes are associated with inflammatory processes and the presence of excessive pro-oxidant free radicals in the body,” according to TAP’s Dr. Tim Bond, “The proven antioxidant and anti-inflammatory effects of black tea flavonoids may therefore be responsible for the positive health effects of black tea.”
We at the Whistling Kettle have always advocated that you mix your tea types, because both black, green, white and oolong teas contain not only varying amounts of anti-oxidants, but the forms are different as well. Black tea is higher in theflavins, whereas green tea is high in catchetins.
For diabetes, we also recommend Matcha because of it's extreme concentration of catechins, which lowers blood sugar. This is further enhanced by fiber - which is contained in Matcha.
