Watercress: The Miracle Food
Watercress is called Sai Yeong Choy in Cantonese
UK Scientists say watercress is
the new super food, able to prevent certain types of cancer. According
to a study published this week in The British Journal of Nutrition, the
consumption of a three ounce portion of watercress reduced the presence
of a key tumor growth factor six to eight hours after eating the
watercress in healthy patients who had previously been treated for
breast cancer.
The study was conducted by the
Cancer Research Center at the School of Medicine, Southampton General
Hospital in the United Kingdom and concluded watercress is as
therapeutic as traditional drug treatments with tamoxifen &
herceptin, commonly used chemotherapy drugs.
The study also said that through
regular consumption, watercress "has the potential to confer
valuable protection against cancer in general." "Watercress
has the ability to turn off HIF1, a signal sent out by cells calling
for blood supply," said noted aging scientist Dr. Nicholas
Perricone.
When HIF1 becomes incorrectly
regulated, otherwise harmless precancerous clusters of cells have the
opportunity to grow to form invasive tumors. "Scientists
have been looking for anti-angiogenesisagents for years because if we
can turn off the blood supply, we can kill the cancer," said
Perricone. "And it looks like watercress can do that."
Another study published in The
American Journal of Clinical Nutrition in February of 2007 showed that,
inaddition to reducing DNA damage, a daily dose of watercress increased
the ability of cells to further resist DNA damage that may be caused by
free radicals.
In the study, 60 men and women,
half of whom were smokers, consumed their usual diet plus 85 grams of
raw watercress daily for eight weeks. Blood samples were analyzed for
plasma antioxidant status and DNA damage in lymphocytes, a type of
white blood cell. Watercress consumption significantly reduce dlymphocyte
DNA damage. In the time of the Romans, Greeks and Persians watercress
was used as a natural medicine, prescribed for migraines, anemia,
eczema, kidney and liver disorder and tuberculosis.
