Green Tea Extract Gives You Benefits ofGreen Tea With No Losses
- The benefits of green tea are well documented. It is one of those natural
products used for thousands of years which has shown many benefits in modern
studies.
Here is a fairly complete list, though
I've made no attempt to find every one.
Studies published in medical journals
have shown that green tea...
* Improves cognitive performance --
keep you alert and working more efficiently
* Treats stomach disorders, like
vomiting, diarrhea and headaches.
* Is a diuretic (improving urine flow)
* Aids weight loss
* May be beneficial in solid tumor
cancers and to reduce the risk of breast cancer, prostate cancer, colon cancer
and gastric cancer.
* May help maintain remission in people
with Crohn's disease
* May help prevent Parkinson's disease
* Appears to protect against heart
disease, tooth decay and kidney stones
* Helps prevent skin damage from
ultraviolet radiation (for example, sunburn) and other environmental causes.
Green tea is different from black teas
because it is not fermented.
For that reason (forgive the big
scientific words about to land on you, I promise they're the last in this
article) the green form has much higher levels of polyphenols such as gallic
acid and catechins such as epigallocatechin gallate (EGCG), epigallocatechin
(EGC), epicatechin gallate (ECG) and epicatechin (EC). All of these are
abundant in green tea and are believed to be responsible for many of its
benefits.
Green tea also contains 2-4 percent
caffeine, or an average of about 40 mg of caffeine per cup. The caffeine
stimulates our central nervous system, like caffeine from any source. That
explains the improvement in alertness, and why we do better on mental
performance tests when we use caffeine.
It's also a potential problem. Even
though the amount of caffeine is less than black tea and coffee, some people
are very sensitive to caffeine and want to avoid it completely.
One other fact about all teas: they all
contain some fluorides. No studies have ever shown ill effects from the amount
of fluoride ingested by drinking an ordinary amount. For example, the amount of
fluoride in five or 10 cups a day, more than most of us are ever likely to
drink, appears to be harmless over a lifetime. But many people would prefer to
leave fluoride out of their daily diet, too.
If either is a concern, the answer is
simple: green tea extract. As part of a balanced supplement, a good extract
provides all the benefits of green tea, without either the caffeine or the
fluoride.
One thing to keep in mind. All tea is
not the same -- and neither are all extracts. Polyphenols and catechins in
green tea (especially the EGCG mentioned above), are usually identified as the
active ingredients that provide the amazing variety of health benefits of green
tea.
Here is the difference in extracts. The
percentage of catechins in green tea extract can range from 20 percent to 80
percent. Since I like a supplement with the most for my money, I take one that
contains only the 80 percent version.
Also, even with all the well-proven
benefits of green tea, no food ingredient is the Lone Ranger. All nutrition
depends on a variety of good things happening in the body, and I want my
supplements to contain other antioxidants and polyphenols that have been proven
in their own clinical studies.
