Does Green Tea have any effect on Cancer?

Green Tea Polyphenols (GTP), particularly EGCG or EGCg (epigallocatechin gallate) not only inhibit an enzyme required for cancer cell growth, but also kills cancer cells with no ill effect on healthy cells.

Dry green tea leaves are about 40% polyphenols by weight, and the most potent of these is EGCG. A team of scientists at Purdue University determined: “In the presence of EGCg, the cancer cells literally failed to grow or enlarge after division then presumably because they did not reach the minimum size needed to divide they underwent programmed cell death, or apoptosis.” EGCG, an antioxidant, is considered many times more potent than the Vitamin E or Vitamin C antioxidant properties. In 1997 study, researchers from the University of Kansas determined that EGCG is twice as  powerful as resveratrol.

Green Tea is also a key element of cancer prevention. “Researchers have known for years that the incidence of prostate cancer is considerably lower in Asian countries. One possible explanation advanced by scientists is the high consumption of plant foods among Asian populations. Another is the growing number of laboratory studies indicating that green tea — the most popular tea in China, Japan and other Asian countries has anti-tumor effects.

Green tea is the most consumed water based drink after water itself! Tea is also the most beneficial drinks apart from natural  fruit juices. Green tea contains more polyphenols chemicals that act as powerful antioxidants and nontoxic, cancer preventive agents than black tea. It has been speculated that the low lung cancer rate in Japan in spite of  high rate of smoking is due to green tea consumption.”
