While herbal
"teas" can be brewed from the leaves, flowers, or even roots of almost
anything that grows out of the Earth, true tea - both green and black -
comes from the leaves of Camellia sinensis. The difference in taste and
in health benefits comes from the way the tea leaves are processed: to
make black tea, the leaves are fermented, which oxidizes many of the
antioxidants present in the leaves, while green tea is produced by
lightly steaming the fresh-cut leaf.
Green Tea was brought to
Japan by Buddhist monks from China, and the Japanese people quickly
embraced the soothing, grassy brew. Today, the citizens of Japan boast
the longest average lifespan in the world, and there are reams of
research to suggest that green tea is a major factor in their robust
health.
Research in experimental animals has found green tea or its extracts
to be effective against chemically-induced cancers of the lung, breast,
colon, liver, and skin, as well as a variety of gastrointestinal organs,
cancers induced by chemical carcinogens; more excitingly, Green Tea
extracts have been found to protect animals from existing, spontaneous
prostate cancer. More important to us is the human evidence for the
health benefits of Green Tea consumption. Extensive epidemiological
evidence shows that people consuming high amounts of Japanese sencha
green tea live longer develop less Cancer, have healthier Cholesterol
levels, suffer less cardiovascular and liver disease, and may be less
susceptible to heart attacks.
The evidence for the cancer-fighting powers of green tea is so strong
that human clinical trials of green tea powders and extracts are now
under way at the Memorial Sloan-Kettering Cancer Center and at other
clinical centers in the United States.
How Much Tea?
But other studies have found no
difference in cancer incidence among higher and lower drinkers of Green Tea. In the most infamous example, a study published in 2001 in the New
England Journal of Medicine found no protective effect of green tea
consumption against gastric Cancer, despite the fact that numerous
previous studies had found that drinking green tea does provide a shield
against this killer. As with so many other things, the key appears to
lie in the amount of green tea being consumed. In the New England
Journal of Medicine study, drinking five or more cups of green tea a day
put people into the highest consumption group. By contrast, the most
consistent epidemiological evidence for a protective effect of green tea
comes from the consumption of ten cups or more of Japanese sencha per
day.
How Do You Get that in Pills?
Few Westerners
drink this much Green Tea. So to get green tea's benefits, many
health-conscious people have turned to standardized extracts of the
green tea leaf itself. That seems to be an especially attractive option
when many companies advertise small green tea pills which allegedly
contain the equivalent of five to ten cups of Green Tea apiece.
Unfortunately, nearly all green tea extract capsules contain only a
fraction of the green tea "cup-equivalents" than their manufacturers
claim.
These companies aren't flat-out lying, but they're using the wrong
yardstick - or, to be more precise, the wrong cup. The problem is that
the amount of EGCG (the main Cancer-fighting component) and other
goodies in a cup of green tea can vary over a wide range, depending on
the kind of green tea, the region where it's grown, the brewing time,
tea leaf, kind of teabag - and, of course, the size of the cup! By
choosing to compare a supplement to the poorest-quality green tea
infusions, supplement companies use "creative accounting" to evaluate
the potency of their pills. They can inflate the comparison, asserting
that their products' 100 to 200 milligrams of EGCG is equivalent to five
to ten cups of Green Tea.
But this is just misleading. When all of these factors are taken into
account, and when you consider that the most consistent research on
green tea's health-enhancing effects in humans comes from drinkers of
Japanese sencha, the "gold standard" cup of green tea can contains 150
milligrams of EGCG. This means, unfortunately, that few green tea
capsules even deliver the equivalent of even one full cup of Japanese
green tea a day - let alone the ten cups that is most consistently
associated with good health and long life.
If you're looking to use Green Tea for longevity and to guard against
age-related disease, it only makes sense to get the best-backed dose of
the best-backed molecule. Indeed, it's these kinds of doses - 800 to
1600 milligrams of EGCG per day that are being used in the human
clinical trials that have begun in the last few years.
The Caffeine Conundrum
Green tea contains very
little caffeine compared to coffee - but of course, it can still add up
if you start drinking ten cups of the steaming brew a day. Indeed, one
clinical trial which has been using ground tea solids as its ‘drug' has
reported significant side-effects - including insomnia, fatigue,
confusion, nausea, diarrhea, stomach pain, and even vomiting - linked to
the caffeine content.
Some green tea supplements are fully decaffeinated to avoid any such
problems. While this approach is better than adding as much as 500
milligrams of extra caffeine to your day, these supplements are
inherently less effective than real tea, because several studies have
found that caffeine itself plays a significant role in the Cancer-fighting powers of Green Tea.
There are other benefits to moderate intake of caffeine, despite the
clear negative impacts of being a full-fledged caffeine junkie. For
instance, a large body of research now suggests that modest caffeine
consumption reduces your risk of developing Parkinson's disease -
probably as a result of caffeine's ability to modulate adenosine A2A
receptors in the brain. Another example: Green Tea polyphenols and
caffeine synergize to increase the body's thermogenic fat-burning
activity - effects with important implications for the Battle of the
Bulge, which is an engagement important for health and vanity alike.
Thus, rigorously eliminating the caffeine content from Green Tea -
whether you get it in cup or capsule - is not the best strategy for your
long-term health. While a zero-tolerance approach may be the only way
for a few extremely caffeine-sensitive individuals to get the benefits
of EGCG, most people will be better off getting at least a little
caffeine in with their green tea. Lightly-caffeinated green tea extracts
provide a happy medium between caffeine-induced side effects and the
loss of significant health benefits.
Putting it All in a Capsule
So getting the full
benefits of Green Tea - an icon of Zen simplicity - turns out to involve
taking a lot of factors into consideration. Green tea extracts should
be HPLC standardized to their content of EGCG. They should make it
convenient to get 1500 milligrams of EGCG a day, to match the strong
epidemiological evidence of health benefits in Japanese sencha drinkers.
And they should contain at least a little caffeine, so that the
often-synergistic interactions between EgCG and caffeine can be
unleashed. Put it all together, and you'll have squeezed a remarkable
amount of health benefit into a few small capsules.

Les catéchines
du thé vert aident à prévenir l'oxidation des lipoprotéines retrouvées
dans le plasma en augmentant la capacité antioxydante du sang.
Les citoyens du Japon ont la chance d'avoir une des plus longues
durées de vie dans le monde. Les études suggèrent que la consommation de
thé vert soit un facteur important dans cette précellence.
L'évidence
épidémiologique prouve que les gens consommant beaucoup de thé vert
japonais sencha vivent plus longtemps. Ils développent moins de cancer,
ont des niveaux plus sains de cholestérol, souffrent moins de maladies
cardio-vasculaires et d'affections hépatiques, et sont peut être moins
susceptibles aux crises cardiaques. En fait, une tasse de thé vert a une
plus grande activité antioxydante qu'une portion standard de brocoli,
d'épinards, de carottes ou de fraises.
L'EgCG ou l'épigallo-catéchine gallate est la catéchine
principale, en importance, et la plus efficace des catéchines qui sont
présentes dans le thé vert. Les études cliniques sur les effets
bénéfiques du thé vert chez l'humain viennent des buveurs de thé sencha
japonais (le standard par excellence du thé vert), qui peut contenir 150
milligrammes d'EgCG par tasse. La quantité de thé vert utilisée dans
ces études à long terme est de 10 tasses (ou plus) par jour, ce qui
équivaut aux 800 à 1600 milligrammes d'EGCG par jour utilisés dans des
essais plus récents.
Le thé vert contient relativement peu de
caféine comparée au café mais 10 tasses par jour peuvent apporter un
total d'environ 500 milligrammes du stimulant. L'absence complete de
caféine dans les extraits de thé vert risque ne pas apporter les
meilleurs résultats, parce que les études suggèrent qu'une quantité
modérée de caféine fournit un avantage synergique à la catéchine de thé
vert.
