There is substantial in vitro and in vivo evidence implicating tea polyphenols as chemopreventive agents against various cancers. In a case-control study conducted among Asian-American women in Los Angeles County, we reported a significant inverse relationship between intake of green tea and risk of breast cancer (A. H. Wu et al., Int. J. Cancer, 106: 574-579, 2003). Because catechol-containing...

Green tea polyphenols have demonstrated significant antioxidant, anticarcinogenic, anti-mutagenic and antidiabetic in numerous human, animal and in vitro studies. Hence present study was design to evaluate the influence of green tea in streptozotocin induced oxidative stress in mice. Morris water maze, Elevated plus maze and passive avoidance apparatus was used for the evaluation of learning an...

BACKGROUND Green tea is a very popular beverage, and in vitro studies have shown that green tea polyphenols inhibit the growth and cellular adherence of periodontal pathogens and their production of virulence factors. We investigated the epidemiologic relationship between the intake of green tea and periodontal disease. METHODS We analyzed 940 Japanese men aged 49 to 59 years as part of a com...

Epidemiological studies have indicated that regular consumption of red wine and green tea is associated with a reduced risk of coronary heart disease and tumor progression.

Green Tea Has Acute Beneficial Effect on Endothelial Function Scientists studied the effects of 6 grams of green tea, 125 mg of caffeine (the amount contained in 6 grams of tea), or hot water on flow-mediated dilation of the brachial artery in healthy subjects. Flow-mediated dilatation (FMD) of the brachial artery is related to coronary endothelial function and is an independent predictor of ca...
