Green Tea and Polyphenols

What are Polyphenols?
Polyphenols are compounds found in nature. More specifically they are found in plants and provide coloring for some. Their purpose appears to be a potent, natural antioxidant. There are many plants that we consume that contain polyphenols. Concentrations are high in Olive oil and Green Tea and have been the subject of many health articles and promoted to enhance your health.
How do Polyphenols work?
These antioxidants eliminate free radicals, unstable molecules that are the major cause of both aging and disease, in both plants and humans. Free radicals continually attack the body. Free radicals are a normal product of metabolism and result in a process called oxidation. Polyphenols and other antioxidants, including beta carotene (a vitamin A precursor), vitamin C, vitamin E, and selenium, scavenge these free radicals and help to prevent formation of unstable oxygen molecules, known as oxidation. Oxidation can damage healthy cells in the body and have been linked to many diseases including cancer, heart disease and stroke. Polyphenols not only work to prevent diseases but may also help to reduce abnormal cells and inflammation; get rid of cancer causing agents and restore cells back to normal health.
What foods contain Polyphenols?
Unfortunately, polyphenols have a quick life span (short half life) of about 3 hours, thus the scientific reason behind researchers' recommendation to drink green tea a minimum of 8 times a day. EGCG, the most abundant and powerful of green tea's 5 main catechins, is dubbed the 'super antioxidant' because it is 200 times more powerful than the popular antioxidant vitamin E. Just one example is a subgroup of polyphenols, exclusive to green tea, called catechins. These extremely high levels of polyphenols deliver green tea's unique results in several ways.

Green Tea is the #1 source of polyphenols. They include red wine, olive oil, black and green tea. There are many but there are only a few, which contain particularly high levels.
And, research at the University of Geneva, in Switzerland, indicate that green tea raises metabolic rates In addition to caffeine, green tea's catechin polyphenols raise thermogenesis (the rate at which calories are burned) and hence increases energy expenditure.

Not only may green tea protect and heal the body from disease but also clinical trials, conducted by the University of Geneva, in Switzerland, indicate that green tea raises metabolic rates and speed up fat oxidation.
Research is still continuing with green tea and more health benefits continue to be discovered. For instance, EGCG's may one day play a role in treatment of mad cow disease (Nature Structural and Molecular Biology, DOI:10.1038/nsmb743). And the formation of unstable oxygen molecules in the body is unavoidable. Aging, smoke, and environmental pollutants are all sources of the damaging free radicals. Japan and China have benefited from drinking green tea vs. black tea, like the rest of us, for centuries. The west is just now catching on to the benefits of green tea. With green tea being no more harmful than a cup of coffee (and actually containing less caffeine) there's no reason why you shouldn't begin today to benefit from green tea too.

Recent Research Indicates Major Antimutagenic Activity in Green Tea

Used for various purposes in Asian countries for centuries; green tea is now a very popular North American beverage also. 20% of daily global tea consumption is green tea. On any day around the globe, nearly two thirds of the population drinks tea, of one kind or another.
New research is emerging that suggests that green tea holds healing properties that slow the aging process and other age related illness and ailments.
Western culture has adopted a love for green tea in recent history, and as such, its pharmacological active compounds benefits have fallen under intense scrutiny as researchers seek to identify what, if any, benefit this beverage possesses in eradicating or avoiding cancers and other diseases usually associated with the promotion of free radicals. Recently, a research team from the Department of Dermatology at Case Western University in Cleveland, Ohio, conducted a study to see if green tea possessed antimutagenic qualities.
The results, while hardly conclusive and more study is likely needed, indicate that green tea does, in fact, possess some qualities that seem to thwart the creation or spread of certain mutations that are thought to contribute to the creation and spread of cancer, contribute to aging, and lead to other diseases associated with aging.
The results of the study found that WEGT and GTP significantly inhibited the reverse mutation induced by benzo [alpha] pyrene (BP), 2-aminofluorene, aflatoxin B1 (AFB1), as well as methanol extracted from coal tar in Salmonella typhimurium TA100 and/or TA98 in the presence of a rat-liver microsomal activation system. The study attempted to identify antimutagenic activity that was a direct result of interaction with WEGT, and subsequently, GTP. Interestingly, this research carefully studied water extracts from green tea, known also as WEGT, and their significant attributes, including green tea polyphenols (GTP).
When GTP was added, during and after nitrosation of methylurea, the results in a dose dependent fashion were the inhibition of mutagenicity. GTP was also found to inhibit gene forward mutation in V79 cells when treated with AFB1.
This perhaps could hold significance as new studies are formulated to ascertain the healthful benefits of GTP. Free radical inhibition is terrifically difficult and the results of this study could be an indication that green tea is a very effective natural source of accomplishing this restriction. The study also found that the antimutagenic activity of GTP implies that it may affect carcinogen metabolism, DNA adduct structure, the interaction of ultimate carcinogen, or the scavenging of free radicals.
Many ancient cultures believed it possessed healing powers and even the ability to ward off disease and mutations, but this is still relatively new to countries in Europe, Canada, and the United States. Green tea has fallen under much scrutiny as its alleged benefits have been touted for centuries, but it popularity in regions of the West have increased dramatically in recent years.
The study noted as 223(3):273-85 is yet one more confirmation that green tea in solid or beverage form possesses restorative and healthful powers that are just now being discovered. Green tea likely holds a potential that is relatively untapped.
With further study, researchers are becoming increasingly confident that consumption of green tea in any form might be an easy and inexpensive method of giving the body another weapon in its life long fight against diseases such as cancer. Additional studies also are beginning to examine whether or not green tea possess other qualities that can inhibit the mutation of certain compounds that contribute to disease and aging. The benefits of green tea are beginning to be unlocked and additional discoveries seem to be on the horizon.
