* Cardiovascular Health : Black tea is abundant in antioxidants, such as flavonoids, demonstrated to prevent the oxidation of LDL cholesterol, preventing damage in both the bloodstream and at artery walls, and lowering the risk of heart disease. Additionally, it has been shown that black tea flavonoids are able to both improve coronary vasodilation and reduce clots. Polypehnols found in black tea are also very strong antioxidants, and the manganese in black tea may reduce the risk of coronary heart disease by helping cardiac muscle function.
* Cancer Prevention : Polyphenols in tea seem to help in preventing formation of potential carcinogens in the body, particularly in certain types of cancer, such as ovarian, lung, prostate, colorectal, and bladder. Other studies reveal that black tea may help prevent stomach, prostate, and breast cancer. A compound in black tea called TF-2 causes such cancer cells to go into apoptosis (programmed cell death) while normal cells remain unaffected. One study on oral cancer showed that consuming black tea can significantly reduce the risk of oral cancer, particularly in those who smoke cigarettes and use other tobacco products.
* Diabetes : Black tea flavonoids improve insulin sensitivity to protect against diabetes.
* Skin and Hair Health : The antioxidants in green tea may help keep your skin from being plagued by acne, and in some cases have been demonstrated to function equally as well as the harsher benzoyl peroxide used in so many skin products.
* Bone and Connective Tissue : Studies indicate that the bones of regular tea drinkers are stronger than those of non-tea drinkers, even when other variables were adjusted for. Scientists theorize it may be an effect of the powerful tea's phytochemicals.
