What Do They Know? by Unknown Source
Tea is a plant product similar to fruits and vegetables. It
contains natural occurring compounds called phytochemicals that are
powerful antioxidants. These phytochemicals have been identified as
playing a role in decreasing the risk of cancer, lowering blood
cholesterol and building up the immune system. Two principal
phytochemicals in tea are flavonoids and polyphenols. It is
believed that they may actually protect us from the harmful effects
of "oxidants" or "free radicals" which are products of normal body
functions and enter our bodies through pollution, smoking, certain
foods or sun exposure. Free radicals can contribute to disease
processes such as cancer and heart disease. They can also make us
older before our time! Antioxidants neutralize the destructive
potential damage of the oxidants or free radicals.
Flavonoids are vitamin like nutrients that make blood cells less
prone to clotting. What can't clot won't stick to arteries or
trigger a heart attack. Both black and green tea contain
flavonoids.
Black tea also contains a small amount of B vitamins. Two
flavonoids produced during the tea process are theaflavins and
thearubigins. Research has shown them to be effective in reducing
esophageal tumors and damage to lung tissue in the laboratory
setting.
A recent study was conducted by a heart specialist at Brigham
and Women's Hospital in Boston on the effects of drinking tea on
the heart. The study concluded that drinking a single cup of tea a
day could cut the risk of heart attack by 44%. The effect was the
same, whether tea was consumed hot, cold, loose or tea bag form and
milk, sugar or lemon was added.
By the way, according to the Tea Council, you get the same
antioxidant benefit from drinking decaffeinated tea.
If you are taking a medication to thin your blood like Coumadin,
you should check with your physician as to how much black or green
tea you should be drinking. Tea contains vitamin like nutrients
called Flavonoids. Flavonoids are reported to make blood cells less
prone to clotting.
There has been publicity about taking an iron supplement and
drinking tea. Apparently, some feel that tea could interfere with
the absorption of iron. We are not sure if this is true, but we
suggest you drink your tea a couple of hours after taking the
supplement.
One particular polyphenol in tea is called " EGCG" is thought to
be 100 times more powerful than Vitamin C and 25 times more
powerful than Vitamin E. This is also present in the black tea. In
the laboratory setting, EGCG selectively destroys cancer cells
while leaving healthy cells unharmed. It is recognized that there
is a lower incidence of certain cancers in Japan due to the daily
consumption of green tea.
Tea is also an excellent source of fluoride and appears to
inhibit the growth of bacteria associated with decay causing plaque
by drinking just one cup a day.
It has been shown to lower blood pressure and reduce the
incidence of stroke. A 15-year study of men in the Netherlands
concluded that those who drank 4 or more cups of tea a day were 69%
less likely to suffer a stroke.
A more recent study showed women age 65 to 75 increased their
bone density significantly by drinking at least one cup of black
tea. It is believed that the polyphenols in tea protect the bones
and keep them healthy.
Some cosmetic companies, impressed by the positive results of
tea in skin cancer research has added green tea to some of their
products.
The exciting information is ongoing and includes many other
possible health benefits. The one thing we do know for sure is that
adding a cup of tea to your diet can contribute to your well being,
and more importantly, it tastes good!
"Thank God for tea, what would the world do without tea, how
did it exist? I am glad I was not born before tea." Sidney
Smith, clergyman and popular figure.
