Green Tea Boosts Production Of Detox Enzymes, Rendering Cancerous Chemicals Harmless
Concentrated chemicals derived from green tea dramatically boosted production of a group of key detoxification enzymes in people with low levels of these beneficial proteins, according to researchers at Arizona Cancer Center.
Green Tea Consumption and Mortality Due to Cardiovascular Disease, Cancer, and All Causes in Japan

(Annals of the New York Academy of Sciences 928:274-280 (2001))
a decreased relative risk of death from cardiovascular disease was found for people consuming over 10 cups of green tea a day, and green tea also had life-prolonging effects on cumulative survival. These data suggest that green tea has preventive effects on both chronic inflammatory diseases and lifestyle-related diseases (including cardiovascular disease and cancer), resulting in prolongation of life span.Green Tea Fights Fat
[Researchers say the results indicate that catechins in green tea not only help burn calories and lower LDL cholesterol but may also be able to mildly reduce body fat.
"These results suggest that catechins contribute to the prevention of and improvement in various lifestyle-related diseases, particularly obesity," write researcher Tomonori Nagao of Health Care Products Research Laboratories in Tokyo, and colleagues.]

"Moderate consumption of green tea appears safe. There is some evidence that green tea may prevent the occurrence of some forms of cancer, but the mechanisms of action of its specific constituents are poorly understood. Preliminary evidence exists of the potential effectiveness of green tea as a treatment for cancer. Further research into the effects of green tea and some of its constituents would be worthwhile." (Kaegi)
"Population studies demonstrate that green tea consumption may actually be one of the major reasons why the cancer rate is lower in Japan." (Murray)
"Drinking at least one cup of green tea per week appears to reduce the risk of stomach cancer." (Cassileth)
"Green tea polyphenols are potent antioxidant compounds that have demonstrated greater antioxidant protection than vitamins C and E in experimental studies. (Ho)" (Murray)
Despite the much touted health benefits of green tea about its ability to provide protection against cancer, it is advised by the scientists to avoid green tea if you are trying to conceive as it reduces the efficacy of folic acid, which is very important in preventing neural tube defects in the first month after conception. This effect though can be minimized by eating folate rich foods like the greens and the regular usage of folic-acid supplement, but again why to take a chance with a baby. Of course you can have a cup of green tea after the first trimester if you wish to.

An extract of green tea wards off colorectal cancer, animal experiments show.
According to research reported at the Sixth International Conference on Frontiers in Cancer Prevention, sponsored by the American Association for Cancer Research, a standardized green tea polyphenol preparation (Polyphenon E) limits the growth of colorectal tumors in rats treated with a substance that causes the cancer.
Green Tea May Protect Brain Cells Against Parkinson's Disease
(2007/12/14 Science Daily)
Does the consumption of green tea, widely touted to have beneficial effects on health, also protect brain cells? Authors of a new study being published in the December 15th issue of Biological Psychiatry share new data that indicates this may be the case.
The authors investigated the effects of green tea polyphenols, a group of naturally occurring chemical substances found in plants that have antioxidant properties, in an animal model of Parkinson's disease.
