Drinking Tea Fights
Cancer Studies Show
Tea drinkers
rejoice! Studies show that drinking tea reduces the risk
of some cancers in humans. Previously tea was thought to
have cardiovascular benefits, but there is mounting
evidence that tea has cancer-fighting properties as
well. Specifically, the antioxidant properties in green,
black and oolong or real tea are cited in these studies.
These teas originate from the camellia sinensis plant
and are excellent sources of polyphenols or plant
chemicals (phytochemicals).
In particular
real tea is rich in flavonoids, powerful antioxidants,
which have been highly touted as a primary staple in the
diet of the Okinawan people of Japan, otherwise known as
the healthiest people on earth. Herbal teas are derived
from a different plant source and lack the antioxidant
properties of the flavanoids in real tea.
Antioxidants
help protect the body against disease by counteracting
the harmful effects of free radicals - stray, highly
reactive particles that accumulate in the body as
byproducts of metabolism. Free radicals injure
surrounding cells through oxidation. Left unchecked they
can damage cellular DNA and potentially cause cancer.
Antioxidants,
such as vitamins C and E and beta-carotene are free
radical scavengers. But research from both the National
Foundation for Cancer Research and the University of
Kansas reports that green tea is 100 times more potent
than vitamin C and 25 times more potent than vitamin E
at protecting cells from damage linked to cancer, heart
disease and other illnesses. In addition, indications
are that black tea contains the same amount of
phytochemicals as green tea.
Most of the
data supporting the anti-cancer benefits of tea at this
point is derived from animal studies in which animals
were treated with polyphenols equivalent to amounts
consumed by regular tea drinkers. Evidence is the
strongest for prevention of cancers of the oral cavity,
stomach and colon. A few animal studies link tea with a
decreased risk of lung and skin cancers . Studies in
humans have been less consistent but still suggest that
tea has anticancer benefits. So drink tea to your
health!
