Black Tea, Green Tea, White Tea, Terrific Teas April 13 2000. White tea, known mostly to tea connoisseurs, may have the strongest potential of all teas for fighting cancer, according to Oregon State University researchers. They presented the first research ever on white tea March 29th at a national meeting of the American Chemical Society. Among the rarest and most expensive varieties of tea, white tea is produced almost exclusively in China. It belongs to the same species (Camellia sinensis) as other tea plants, but has a higher proportion of buds to leaves. The buds are covered by silvery hairs, giving the plant a whitish appearance. Some teas are processed more than others. White tea is rapidly steamed and dried, leaving the leaves “fresh.” Green tea, composed of mainly leaves, is steamed or fired prior to being rolled. Oolong and black teas get their dark color and flavor from additional processing. The researchers think that processing may play a part in tea’s cancer-fighting potential. The key is a class of chemicals called polyphenols.
Chemical analysis confirmed their theory. White tea contains the same types of polyphenols as green tea, but in different proportions. Those present in greater amounts may be responsible for white tea’s enhanced cancer-fighting potential, says Dashwood. Lab tests on four varieties of white tea showed that it may prevent DNA mutations, the earliest steps leading to cancer. The researchers say that their latest data indicate that white tea may protect against colon cancer in particular. The researchers say more studies are needed to determine whether white tea actually protects people against cancer. “White tea, and tea in general, is a healthy alternative to other popular drinks, such as sodas,” says Dashwood. “But to be on the safe side, one should maintain a healthy lifestyle that includes a diet rich in fruits and vegetables, regular exercise, and avoidance of smoking.” Dr. Dashwood is Associate Professor in the Department of Environmental and Molecular Toxicology at Oregon State University. He also is Principal Investigator with the university’s Linus Pauling Institute. Dr. Santana-Rios is a post-doctoral Research Associate with the Linus Pauling Institute.
Green Tea is
significant in cancer research. Many studies and tests are being done and have
found green tea to be an antioxidant and anti-carcinogen. It inhibits the
formation of the cancer-inducing compound, N-nitrosation. Therefore, it is being
studied as a prevention for esophageal cancer, digestive tract cancer, pancreas
cancer, rectal cancer, small intestine cancer, skin cancers, hepatic cancer,
pulmonary cancer, leukemia, and others, which are still being tested. Green Tea Kills Prostate Cancer Cells
Sip green tea. Green tea is the traditional beverage of Japan and China and appears to reduce cancer in general including prostate cancer. Green tea contains an antioxidant called EGCG which not only kills prostate cancer cells in test tubes but also appears to inhibit enzymes that promote prostate and breast cancer. Suggest you substitute green tea for coffee, black tea or colas. Decaffeinated green tea is also available and still retains its antioxidant affect. Terrific Teas
A particularly potent polyphenol (EGCG) in green tea is 20 times more potent against free radicals than the known vitamin. It also blocks an enzyme that’s responsible for cancer’s spread and has the ability to help trigger cancer cell death. Green Tea. Another staple of Asian populations.

The latest tea discovery? Strong evidence that both green and black tea can fight cancer-at least in the test tube-though green tea holds a slight edge. In a new study, both teas kept healthy cells from turning malignant after exposure to cancer-causing compounds. Prevention, May 2000 "People who drink about 4 cups of green tea a day seem to get less cancer. Now we may know why."In recent test-tube studies, a compound called EGCG, a powerful antioxidant in tea, inhibited an enzyme that cancer cells need in order to grow. The cancer cells that couldn't grow big enough to divide self-destructed. It would take about 4 cups of green tea a day to get the blood levels of EGCG that inhibited cancer in the study. Black tea also contains EGCG, but at much lower concentrations.

"Many
of the more potent tea polyphenols ('catechins') become oxidized or destroyed as
green tea is further processed into oolong and black teas," says Roderick
H. Dashwood, Ph.D., a biochemist in the university’s Linus Pauling Institute
and principal investigator of the study. "Our theory was that white tea
might have equivalent or higher levels of these polyphenols than green tea, and
thus be more beneficial."
Green
tea — Drink at least 4 cups a day or take a standardized extract. Green tea
inhibits cancer cell growth and induces
apoptosis
(programmed cell death).
April
1998. Green tea contains compounds that kill prostate cancer cells. Most people
in the USA and around the world drink black tea, if they drink tea at all. Only
about a quarter of all tea drunk is green. Both kinds of tea leaves are from the
same plant, the evergreen shrub Camellia sinens. Black tea is made from the
withered, fermented leaves. The leaves sold as green tea have been steamed after
picking, and are not fermented. This makes a difference. Green tea, evidence
suggests, is more potent in anti-cancer ingredients.
Teas:
Green Tea and Black Tea
contain certain antioxidants known as polyphenols (catechins) which appear to
prevent cancer cells from dividing. Green tea is best, followed by our more
common black tea (herbal
teas do not show this benefit).
According to a report in the July 2001 issue of the Journal of Cellular
Biochemistry, these polyphenols that are abundant in green tea, red wine and
olive oil, may protect against various types of cancer. Dry green tea leaves,
which are about 40% polyphenols by weight, may also reduce the risk of cancer of
the stomach, lung, colon, rectum, liver and pancreas, study findings have
suggested.
Studies
have linked both green and black tea to a reduced risk of many cancers,
including those of the lung, colon, stomach, skin, breast and pancreas. Drinking
large quantities of green tea (up to 6 cups a day) may explain why Japanese men
have a lower risk of dying from prostate cancer or developing lung cancer than
people in the West.
