Tea reduces breast cancer risk, improves blood vessel function
A new review examining 39 previous studies concluded that tea consumption may lead to a noticeable reduction in breast cancer incidence and an improvement in blood vessel function. Researchers investigated thousands of breast cancer cases and found that regular green tea drinkers had a 21 percent decreased risk of breast cancer, most likely due to the high polyphenol content of green tea. The cardioprotective effects of black tea were also confirmed based on several studies that suggest a link between black tea flavanoids and improvement in blood vessel function.
