Anti-Cancer Compound in Green Tea Identified " . a compound called EGCG in green tea prevents cancer cells from growing by binding to a specific enzyme."

Beat stress, drink tea - study "Men who drank black tea four times a day for six weeks had lower levels of the stress hormone cortisol than subjects in a control group who drank a tea substitute …"

Drinking Green Tea Reduces CVD Mortality "A prospective cohort study of more than 40,000 people in Japan has shown that drinking green tea can significantly cut deaths from cardiovascular disease (CVD) as well as all-cause mortality, particularly in women. There was no beneficial effect of green tea consumption on cancer mortality, however."

FDA Rejects Health Claim for Green Tea

Green Tea and the 'Asian Paradox' " . the average 1.2 liters of green tea consumed daily by many people in Asia offers the anti-oxidant protective effects of the polyphenolic EGCG. EGCG may prevent LDL oxidation, which has been shown to play a key role in the pathophysiology of arteriosclerosis. EGCG also reduces the amount of platelet aggregation, regulates lipids, and promotes proliferation and migration of smooth muscle cells, which are all factors in reducing cardiovascular disease . "

Oxidative-induced retinal degeneration is attenuated by epigallocatechin gallate. (Brain Res. 2006) "The conclusion reached from this study is that EGCG is a powerful antioxidant and when injected into the eye with SNP attenuated the detrimental influence of SNP to retinal photoreceptors. Since oxidative stress has been implicated in retinal diseases like AMD and glaucoma this study provides "proof of principle" for the idea that daily intake of EGCG may help individuals suffering from retinal diseases where oxidative stress is implicated."

Tea Consumption May Reduce Risk for Ovarian Cancer

What are the real benefits of green tea? "Green tea contains relatively high amounts of a type of phytochemical called EGCG, proven in laboratory studies to be a powerful antioxidant. A variety of antioxidants from plant foods seem to stabilize “free radicals,” protecting DNA from damage that could allow cancer to develop, and protecting blood vessels from damage that could promote blockages."

ARTICLES:

Green Tea for Long Life? "The study was conducted with meticulous care. But Kuriyama is quick to point out that this kind of study can't prove green tea has any beneficial effect. Proof comes only from a clinical trial in which some people get green tea and others do not. The Kuriyama study shows only that there is a link between green tea and lower death risk -- not that green tea causes lower death risk."

Is Green Tea Really Beneficial? "The current study lends further credibility to the notion that green tea may improve survival, particularly mortality related to cardiovascular disease and particularly among women. However, the sum of data regarding the benefits of green tea consumption remains conflicting."

JOURNAL ARTICLES:

Anti-obesity effects of green tea: From bedside to bench. (Mol Nutr Food Res. 2006)

Beneficial effects of green tea--a review. (J Am Coll Nutr. 2006) "Tea is the most consumed drink in the world after water. Green tea is a 'non-fermented' tea, and contains more catechins, than black tea or oolong tea. Catechins are in vitro and in vivo strong antioxidants. In addition, its content of certain minerals and vitamins increases the antioxidant potential of this type of tea. Since ancient times, green tea has been considered by the traditional Chinese medicine as a healthful beverage. Recent human studies suggest that green tea may contribute to a reduction in the risk of cardiovascular disease and some forms of cancer, as well as to the promotion of oral health and other physiological functions such as anti-hypertensive effect, body weight control, antibacterial and antivirasic activity, solar ultraviolet protection, bone mineral density increase, anti-fibrotic properties, and neuroprotective power."

Beneficial effects of tea and its polyphenols against prostate cancer. (Mol Nutr Food Res. 2006)

Black tea – helpful or harmful? A review of the evidence (European Journal of Clinical Nutrition (2007)) "There was sufficient evidence to show risk reduction for CHD at intakes of 3 cups per day and for improved antioxidant status at intakes of one to six cups per day. A maximum intake of eight cups per day would minimise any risk relating to excess caffeine consumption. Black tea generally had a positive effect on health. Sponsorship: The Tea Council. The authors confirm that the sponsors played no role in the writing of this review."

Consumption of Antioxidant-Rich Beverages and Risk for Breast Cancer in French Women. (Ann Epidemiol. 2006)

Daily consumption of green tea catechin delays memory regression in aged mice. (Biogerontology. 2006) "We found that daily consumption of GT-catechin prevented memory regression and DNA oxidative damage in these mice. GT-catechin did not prolong the lifetime of SAMP10 mice, but it did delay brain senescence. These findings suggest that continued intake of GT-catechin might promote healthy ageing of the brain in older persons."

Effects of green tea on urinary stone formation: an in vivo and in vitro study. (J Endourol. 2006) "Conclusions: Green tea has an inhibitory effect on urinary stone formation, and the antioxidative action of EGCG is considered to be involved."

Epigallocatechin-3-gallate increases the formation of mineralized bone nodules by human osteoblast-like cells. ( Nutr Biochem. 2006) "The observed effects of EGCG on bone formation by HOB-like cells suggest that EGCG may have beneficial effects on bone health."

Green tea, black tea and colorectal cancer risk: a meta-analysis of epidemiologic studies. (Carcinogenesis. 2006) "Despite the strong evidence from in vitro and non-human in vivo studies in support of green and black tea as potential chemopreventive agents against colorectal cancer, available epidemiologic data are insufficient to conclude that either tea type may protect against colorectal cancer in humans."

Green Tea Consumption and Mortality Due to Cardiovascular Disease, Cancer, and All Causes in Japan (JAMA. 2006) "Conclusion Green tea consumption is associated with reduced mortality due to all causes and due to cardiovascular disease but not with reduced mortality due to cancer. "

Habitual green tea consumption and risk of an aneurysmal rupture subarachnoid hemorrhage: A case-control study in Nagoya, Japan. (Eur J Epidemiol. 2006) "BACKGROUND: Green tea, a popular beverage in Japan, contains many polyphenolic antioxidants, which might prevent cardiovascular disease. This study is designed to determine whether the consumption of green tea is associated with a reduced risk for subarachnoid hemorrhage (SAH) using a case-control study. . CONCLUSION: In a case-control study in Japan, we found that habitual green tea consumption may be strongly associated with a reduced risk for SAH. Our findings will be useful in targeting individuals and populations for the primary prevention of SAH."

Mechanisms of action of green tea catechins, with a focus on ischemia-induced neurodegeneration (The Journal of Nutritional Biochemistry 2006) "Catechins are dietary polyphenolic compounds associated with a wide variety of beneficial health effects in vitro, in vivo and clinically. These therapeutic properties have long been attributed to the catechins' antioxidant and free radical scavenging effects."
