- Green
or White, Choose Tea

"Better to be deprived
of food for three days than tea for one." ~ Chinese Proverb
A half a million years ago some ancient and bold adventurer threw
caution to the wind - and then threw tea leaves into a pot of
hot water and drank the brew. The rest is a storied history of
tea, a history of power and money made from selling it, a history
that has always included the belief that, above all, drinking
tea insures a long and healthy life. In this case it turns out
that the rumor is true.
Tea contains powerful anti-oxidants,
substances that scavenge for free radicals. Free radicals damage
DNA and are considered
to be co-conspirators in the formation of cancer. Tea contains
polyphenols, very powerful anti-oxidants, called catechins. And
the most powerful (and studied) of these is epigallocatechin
gallate, otherwise (and mercifully) known as EGCG.
Tea is processed in several
different ways, but all teas are made from the leaf of the same
plant. White tea is picked as an
immature bud and is unfermented. Green tea is picked as a mature
leaf and is unfermented. Black and Oolong teas are made
from mature leaves that are fermented to varying degrees. It
is the fermentation process that destroys some of the polyphenols,
like EGCG, and this is why the unfermented white and green teas
are better for you.
Though not yet fully understood,
the health benefits of white and green tea appear to be substantial.
In 1994, a paper
published in the Journal of the National Cancer Institute revealed
that Chinese women who drank green tea had a 60% lower
risk of esophageal cancer, a very common and deadly cancer in
China.
And at the University of Purdue
scientists reported that green tea reduced the growth of cancer
cells.
And at the University of Kansas
scientists reported that EGCG was twice as powerful an anti-oxidant
as resveratrol, the
protective substance in red wine that lowers risk for cardiac
disease.
Finally, in 2004 Pace University
scientists concluded that white tea could help the body's immune
system.
Researchers are just beginning
to understand and appreciate the health-promoting benefits of
polyphenols, like those found in
white and green tea, but while we wait for additional studies
and more information about the specific mechanisms by which white
and green tea impart their beneficial effects, it can't hurt
to drink 1-2 cups of white or green tea daily, especially in
the
morning so that the mild dose of caffeine found in these teas
has a chance to wear off by the end of the day.
Play it safe and add white
or green tea to your defensive arsenal. Live long and prosper,
healthfully.
