The Shanghai Women’s Health Study is a large scale statistical survey. One part of it reviewed 70,000 middle-aged or older non-smoking women who drank three cups of green tea or more per week. The statistics showed that these women had a lower risk of colon, stomach, and throat cancer (American Journal of Clinical Nutrition).
Next researchers at Columbia University Medical Center in New York showed a link with green tea extracts (GTEs) inhibiting breast cancer tumour growth among women already with breast cancer.
Then a study from the David Geffen School of Medicine (UCLA) followed men scheduled to undergo a prostatectomy (the removal of a cancerous prostate gland). Those who drank several cups of green tea every day in the weeks before the procedure had less prostate inflammation and lower PSA readings, a protein marker for prostate cancer, than those who didn’t.
The active ingredients are polyphenols and those in green tea are called catechins. These have been shown in research to inhibit blood supply formation to tumours. The most abundant catechin in green tea is epigallocatechin gallate, EGCG.
EGCG has been shown by
Dr Young S. Kim of the
National Cancer Institute to inhibit the regrowth of tumours. EGCG is known to have strong epigenetic benefits, and can coreect and reverse damage to the genome.
