This news about green tea may be a good news for those who are affected by prostate cancer.
If you have a prostate cancer then drinking green tea may be a good health option for you.
A recent study conducted at Louisiana State University has shown the slow progression of prostate cancer in males who were given the doses of polyphenon E found in green tea.
Dr.
James Cardelli with his colleagues conducted a clinical trial on 26 men ageing between 41 and 68 years to find out the effects of active compounds found in green tea in the form of short term supplements given to the patients.
What they found was that given in short term supplementation, polyphenons have the ability of limiting the levels of serum associated with the growth of prostate cancer thus preventing them from the disease to some level.
The quantity of polyphenon E given to the men was 1.
3 grams daily which is equivalent of 12 cups of tea drunk daily.
There had been studies on the association between the two earlier also but evidence was inconclusive as according to FDA people consumes small quantities only.
But now according to the clinical trial conducted by Dr James and his team on 26 men have proved that green tea though drunk in acceptable quantity can significantly reduce the risk of the disease.
There are three bio-makers in the serum associated with the growth of cancer.
These are HGF (Hepatocyte Growth Factor), VEGF (Vascular Endothelial Growth Factor) and PSA (Prostrate Specific Antigen).
Doses of polyphenon E given to the men for a period of 12 to 75 days shew the drop of 18.
9 percent in HGF, 9.
9 percent in VEGF and 10.
4 percent in PSA.
Some men showed the drop by 30% even.
There were higher levels of ECGF which blocked the production of HGF, and VEGF.
This is in contrast to the earlier studies performed on ECGF which proved the adverse effects on liver of having higher levels of ECGF.
This clinical test conducted by Dr.
James almost proves the role of polyphenon E in preventing the prostate cancer but Dr.
James at the same time says that the test is in early stage so lot of further study needs to be conducted in order to prove the benefits of green tea in preventing prostate cancer.
