Watercress the new super food 西洋菜是新的超级食品
Sai Yong Choi (or Watercress), good for health and able to prevent certain types of cancer.
Nothing to lose. Try for less than $2 ,maybe once a week. The locals here add them raw to their green. We usually boil soup with it with pork bones as soup base although the boiling may destroy some of its potentials. Eating things raw has its risks too esp nowadays. Hot soup good for cold weather like winter coming soon here. For some unknown reasons, our local born sons love the watercress soup, surprising even the watercress itself!
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 and eight hours after eating the watercress in healthy patients who had previously been treat ed for breast cancer.
The study was conducted by the Cancer Research Centre at the School of Medicine , Southampton General Hospital in the United Kingdom .
The study concluded watercress is as therapeutic as traditional drug treatments with tamoxifen and 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-angiogenesis agents 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 , in addition to reducing DNA damage, a daily dose of w at ercress 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 st at us and DNA damage in lymphocytes, a type of white blood cell. Watercress consumption significantly reduced lymphocyte 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.
