The four thousand-year-old
secret of green tea's medicinal properties is becoming more
apparent each year. Research is being conducted in Asia,
Europe, and the United States. Studies are finding that the
compound epigallocatechin gallate (EGCG) found in green tea
helpful in a number of medical conditions, including cancer,
rheumatoid arthritis, high cholesterol, cardiovascular disease,
and infections.
What Makes Green Tea
Effective
Green tea is rich in catechin polyphenols, in
particular epigallocatechin gallate (EGCG). EBCG is an
antioxidant. Let's define these terms:
Antioxidants are substances or nutrients in food
which can prevent or slow down oxidative damage in
the body.
Catechin is a bioflavonoid and a powerful
antioxidant.
Flavonoids are a group of chemical compounds found
in plants that have antioxidant and
anti-inflammatory properties.
Polyphenols are compounds found in green tea known
to have antioxidant qualities which help the body
to fight damage caused by free radicals.
Free radicals are molecules in the body that
contain oxygen and attack cells in the body.
The cells in our body use oxygen which produces
a by-product known as free radicals. These free radicals attack
the cells in the body causing damage such as the development of
cancer cells. Antioxidants inhibit and repair the damage caused
by the free radicals.
Other teas, such as black tea and oolong, do
not have the same health benefits as green tea. Green tea is
steamed and does not lose its oxidation. Black tea and oolong
tea are fermented and that allows water to evaporate which
causes oxidation. The result is that EGCG is converted into
other compounds that are not as effective in preventing and
fighting various diseases.
Green tea is also effective in killing the
oral bacteria that forms as plaque on and
around the teeth. Studies are showing that green tea can be
effective in weight loss. In ancient China, the people of
the Southern Provinces changed from green tea to black tea
because they lost weight and they needed the weight to
maintain fighting strength during the social upheavals of
the time.
How Much Green Tea Do You Need
Daily
Researchers have not found a definitive
answer as to how much green tea you should drink in a day.
The amount ranges from two cups per day to ten cups per
day depending on the study you read. The average amount
seems to be four to five cups per day.
Green tea is an acquired taste. There are
different types of green teas and some are sweeter than others.
You can add sweeteners, sugar, honey, or milk to the tea. Some
research studies have found that these additions do not break
down the antioxidants in green tea.
You can drink as much as you like, although
drinking more than four or five cups may not provide any
additional health benefits.
For over 4000 years the natural ingredients of
green tea have been used for medicinal purposes. Studies of its
health benefits are ongoing. The only negative thing about
green tea is that it does contain caffeine. However, there is
less caffeine in eight ounces of green tea (about 60 mg) than
there is in eight ounces of coffee (over 100 mg).
So, if caffeine does not bother you, enjoy your
green tea!
