This recent study shows a huge effect at reduction of risk of prostate cancer. All men over 40 should be taking a high potency green tea supplement (maybe younger men as well). I’ve tested a lot of them and find one capsule a day in the morning of Life Extension Foundation Mega Green Tea Extract works best.
Green tea reduces prostate risk
21/04/2005 – Green tea is back in the news again after a new study showed that men at a high risk of contracting prostate cancer had their risk slashed after taking green tea catechins for a year.
The study – whose results were made public yesterday at the 96th Annual Meeting of the American Association for Cancer Research – found that after a year’s oral administration of green tea catechins (GTCs), only one man in a group of 32 at high risk for prostate cancer developed the disease, compared to nine out of 30 in a control.
“Numerous earlier studies, including ours, have demonstrated that green tea catechins, or pure EGCG (a major component of GTCs), inhibited cancer cell growth in laboratory models,” said Dr Saverio Bettuzzi, who led the Italian research team. “We wanted to conduct a clinical trial to find out whether catechins could prevent cancer in men. The answer clearly is yes.”
The researchers said that earlier studies demonstrated primarily that green tea catechins were safe for use in humans, while they have newly identified that EGCG targets prostate cancer cells specifically for death, without damaging the benign controls.
And added that they had identified Clusterin, the most important gene involved in apoptosis, or programmed cell death in the prostate, as a possible mediator of catechins action. “EGCG induced death in cancer cells, not normal cells, inducing Clusterin expression,” said Bettuzzi.
