“If we do not find time to take care of our health, we will
reluctantly have to find time for our illness”
-Hippocrates

Lately there’s a lot of buzz in the news and online about
green tea and its’ health benefits, particularly the role of
polyphenols in green tea.

Polyphenols are chemical compounds found in fruits,
vegetables and green tea and further divided into sub groups
called catechins. There are 4 major catechins in green tea
of which EGCG ((-)-epigallocatechin gallate (EGCG) is the
most potent and found in abundance in green tea.

This compound is dubbed the “super antioxidant” because it’s
more powerful than the popular antioxidants Vitamin E &
Vitamin C. This super antioxidant eliminates free radicals,
the unstable molecules in the body that are the major cause
of both aging and disease, which continually attack the body
and leave the body vulnerable to disease.

Free radicals disrupt the biochemical processes within
cells, and our body’s natural defenses become compromised
leading to illness. Free radicals indiscriminately kill
cells, destroy enzymes and produce toxic chemicals which
cause damage to cellular functions. They are highly reactive
molecules; their activities cause damage to critical
structures such as DNA, lipids and proteins. All of which
are vital for normal cellular function.

Free radicals in the body are toxic forms of reactive oxygen
metabolites (ROM). It’s ironic that on one hand oxygen
sustains us and on the other hand oxygen can be responsible
for much of the destruction and aging of our cells. Free
radicals are responsible for many ailments including but not
limited to aging, cancer, heart disease, stroke and
arthritis. Without an antioxidant line of defense, your
cells oxidize or breakdown faster thus speeding up the aging
process, it’s the free radicals oxidative damage that makes
us age.

Since EGCG contained in green tea is a potent antioxidant it
neutralizes free radicals and hence is responsible for the
health promoting benefits listed below.

Lower total cholesterol and LDL (bad)-cholesterol levels
Increase HDL (good)-cholesterol levels
Reduce the risk of cancer
Reduce the risk of heart attack
Decrease the risk of stroke
Decrease the risk of developing rheumatoid arthritis
Enhance immune function
Act as an antibacterial and antiviral agent
Help in weight loss
Boost longevity due to potent antioxidant properties

One cup of green tea usually provides 100-300 mg of
polyphenols and contains EGCG in high concentrations. As
mentioned above EGCG is believed to possess 100 times more
potency as an antioxidant than vitamin C and at least 25
times more potency than Vitamin E and protects cells and DNA
from damage believed to be linked to cancer, heart disease
and other potentially fatal illnesses.

Green tea has been used for centuries in China for the
health benefits it provides. We’re just now scratching the
surface of what green tea has to offer, new studies come out
constantly that provide data on the effectiveness of green
tea against various ailments. The latest research indicates
that green tea may help in Alzheimer’s disease by decreasing
the production of a protein which in large amounts causes
nerve damage and memory loss. All of the benefits of green
tea can be attributed to polyphenols, particularly EGCG.

Green tea comes in various dosage forms but the more popular
versions are the liquid forms and the patch. The patch seems
to be gaining in popularity due to the convenience factor
and delivery of the same amount of the active ingredient of
green tea at a constant rate. Place the patch on the skin
and wear it for 48 hours and replace it every other day. It
can’t get any simpler than that

As you can see EGCG is an important component of green tea
responsible for all of the health benefits listed above.
Recent studies also indicate green tea as being effective in
promoting weight loss.

Green tea is truly a ‘wonder compound’ with a large array
of benefits for improving
health. It’s been around for thousands of years and now it
has finally been re-discovered
for our benefit.

-A discovery is said to be an accident meeting a prepared mind, Albert von Szent-Gyorgyi (1893 - 1986)

Or as I like to say When the student is ready, the teacher shall appear! By the way, have I said how much I passionately enjoy green tea, the personal benefits I have witnessed from green tea and what a fantastic unearthing this ‘ancient medicine’ is for modern western living?

After a good deal of research, I have found that there isn’t any other food or drink in general consumption reported to have the innumerable health benefits that green tea possesses…none!

The Chinese have known about the medicinal benefits of green tea since ancient times, using it to treat everything from headaches and lethargia to depression. And did you know that green tea has been used as a medicine in China for over 4,000 years When will we westerners learn?

At present, in both Asia and America, scientific research is providing a more than solid substantiation for the health benefits long associated with drinking green tea. For instance, in 1994 the Journal of the National Cancer Institute published the results of an epidemiological study demonstrating that drinking green tea reduced the risk of esophageal cancer in Chinese men and women by nearly sixty percent. Conversely, University of Purdue researchers recently concluded that a compound in green tea inhibits the growth of cancer cells. There is also research indicating that drinking green tea lowers total cholesterol levels, as well as improving the ratio of good (HDL) cholesterol to bad (LDL) cholesterol.

To abridge just a few of the medical conditions in which drinking green tea has proved to be helpful:

impaired immune system function

cardiovascular disease

cancer

rheumatoid arthritis

elevated cholesterol levels

numerous types of infections

muscle wasting diseases

Green tea’s ’secret’ lies in the fact it is rich in catechin polyphenols, particularly epigallocatechin gallate (EGCG). EGCG is a powerful anti-oxidant: besides inhibiting the growth of cancer cells, it kills cancer cells without harming healthy tissue. It has also been exceedingly effective in lowering LDL cholesterol levels, and inhibiting the abnormal formation of blood clots. The preceding takes on added importance when you consider that thrombosis (the formation of abnormal blood clots) is the foremost cause of heart attacks and stroke. Quite startling, don’t you think?

For The Record Books

Correlates are being drawn between the effects of drinking green tea and the “French Paradox.” For years, researchers were mystified by the fact that, despite consuming a diet rich in saturated fat, the French have a lower incidence of heart disease than Americans. The answer was found to lie in red wine, which contains resveratrol, a polyphenol that limits the negative effects of smoking and a fatty diet. In a 1997 study, researchers from the University of Kansas concluded that EGCG is twice as powerful as resveratrol, which may explain why the rate of heart disease among Japanese men is significantly low, even though in excess of seventy-five percent are smokers.

So why don’t other Chinese teas have similar earth-shaking health benefits? Green, oolong, and black teas all come from the leaves of the Camellia sinensis plant. What sets green tea apart is the way it is processed.In particular, green tea leaves are steamed, which prevents the EGCG compound from being oxidized. By contrast, black and oolong tea leaves are processed from fermented leaves, which results in the EGCG being transformed into other compounds that are not nearly as effective in preventing and fighting various conditions and diseases.

Some Additional Benefits

The latest evidence emerging is that green tea can even help dieters attain success more rapidly an efficiently. In November, 1999, the American Journal of Clinical Nutrition published the results of a study at the University of Geneva in Switzerland. Researchers found that men who were given a combination of caffeine and green tea extract burned more calories than those given only caffeine or a placebo.

Incidentally, green tea can even help prevent tooth decay! Just as its bacteria-destroying abilities can help prevent food poisoning, it can also kill the bacterium that causes dental plaque. Meanwhile, skin preparations containing green tea - from deodorants to creams - are starting to appear on the market showing positive effects.

The Potential Unsafe Effects?

As of today, the only adverse side effect reported from drinking green tea is mild insomnia due to the fact that it contains caffeine. On the other hand, green tea contains much less caffeine than coffee and most soda: there are approximately thirty to sixty mg. of caffeine in six - eight ounces of tea, compared to over one-hundred mg. in eight ounces of coffee and can you imagine the huge contrast in caffeine content between green tea and these ‘new’ high-tech energy drinks that are currently being consumed by the masses with such ravenous voracity.

Green Tea Polyphenols, What Are They You Ask?

Specifically, tea polyphenols are compounds in tea leaves that are natural plant antioxidants. Antioxidants have been proven to prevent damage caused by free radicals to DNA and other molecules.

How Do They Work?

Green tea polyphenols have corroborated several cancer preventive properties. In addition to antioxidant activity, these compounds may as previously mentioned have shown to reduce abnormal cell growth and inflammation; help the body get rid of cancer-causing agents; and restore communication between different cells in the body.

On Cancer The Facts

The relationship between green tea consumption and human cancer has been studied in several different populations and at various cancer sites. Some of the studies comparing green tea drinkers to non-green tea drinkers support the claim that green tea-drinking, in fact prevents certain types of cancer. Certain dietary, environmental, and population differences may account for these discrepancies. In animal studies, different tea extracts, tea polyphenol mixtures, purified tea components, and tea infusions as the sole drinking fluid have more consistently been shown to prevent cancer, including cancers of the colon, esophagus, liver, stomach, lung, breast, pancreas, and skin. The purified component, epigallocatechin gallate (EGCG), prevented colon cancer, but did not prevent cancer of the esophagus in animal models. A polyphenol mixture with EGCG, called Polyphenon E, has also shown cancer preventive properties in animals. Animal studies were inconclusive as to whether EGCG or Polyphenol E caused DNA mutations that might trigger cancer growth. Both EGCG and Polyphenon E are being tested for safety and efficacy in humans.

Slower Prostate Cancer Cell Growth Found From Consumption Of Green And Black Tea

A study at The Experimental Biology 2004, in Washington, D.C., reported as part of the scientific program of the American Society of Nutritional Sciences, anti-tumor effects of green and black tea polyphenols in human tissue. And researchers at the University of California at Los Angeles found and were able to detect tea polyphenols in prostate tissue after a very limited consumption of the tea. More notably, the scientists found that prostate cancer cells grew more slowly when placed in a medium containing blood serum of men who had consumed either green or black tea for five days compared to serum collected before the men began their tea-drinking regimen. Serum from men who drank comparable amounts of diet or regular soda showed no such slowing in cancer cell proliferation.

Consequently, Dr. Susanne Henning, UCLA Center for Human Nutrition, pronounced that the UCLA research team - a combination of nutrition scientists and urologists - focused on the feasible outcome of tea polyphenols on factors named polyamines and the enzymes responsible for the production of polyamines. Elevated levels of polyamines have been connected with malignancy in humans, including prostate cancer, and - since polyamines are current in prostate tissue in high concentration - are considered a logical target for chemoprevention of prostate cancer.

Prostate cancer is one of the most widespread cancers among males in the United States, and more than a fourth of all those patients with prostate cancer are known to use alternative therapies, including green tea. This study suggests that both black and green tea are promising natural dietary supplements useful for chemoprevention of prostate cancer, according to Dr. Henning. She plans to investigate if this effect can be enhanced by consuming larger amounts of tea polyphenols in the form of green tea extract supplement capsules.

So If It’s That Good, How Much Should I Drink?

Strangely enough, there are as many answers to this question as there are researchers investigating the beneficial properties of green tea and polyphenols. Herbs for Health magazine mentions a Japanese report citing that men who drank ten cups of green tea per day stayed cancer-free for three years longer than men who drank less than three cups a day (there are approximately 240 - 320 mg of polyphenols in three cups of green tea).

Meanwhile, a study by Cleveland’s Western Reserve University concluded that drinking four or more cups of green tea per day could help prevent rheumatoid arthritis, or reduce symptoms in individuals already suffering from the disease. And Japanese scientists at the Saitama Cancer Research Institute have discovered that there were fewer recurrences of breast cancer, and the disease spread less quickly, in women with a history of drinking five cups or more of green tea daily.

A University of California study on the cancer-preventative qualities of green tea concluded that you could probably attain the desired level of polyphenols by drinking merely two cups per day. So which is it? I personally don’t buy the hype that those that manufacture and sell green tea products are propagatingmoderation is, like with all things probably your best bet! But given all the evidence, it is almost certainly safe to plan on drinking four to five cups of green tea daily. If you’re a real aficionado, by all means imbibe more; but whether or not you’ll derive added health benefits remains to be determined.

Okay, enough science Let’s all just relax and have a cup of green tea or if you like your beverages cold like I do, a glass of ‘iced’ green tea.
