(NaturalNews) Many studies have demonstrated evidence of several health benefits  from drinking green tea, including lowering the risk of cancer.
A recent  large scale statistical survey to determine green tea’s cancer prevention  potential, first reported by Reuters then published in the American  Journal of Clinical Nutrition, was conducted by Shanghai Women’s Health  Study.
This study involved almost 70,000 middle-aged or older  non-smoking women who drank green tea regularly. The statistics showed that  these women had a lower risk of colon, stomach, and throat cancer.
The  required green tea consumption amount was rather low for the study, only three  times weekly. Those who drank more green tea with longer consumption histories  demonstrated statistically lowered cancer risks than those who only met the  minimum study requirements.
Another recent test at Columbia University  Medical Center in New York showed a link with green tea extracts (GTEs)  inhibiting breast cancer tumor growth among women with beast  cancer.
How about green tea for men? Another study at University of  California Los Angeles David Geffen School of Medicine was conducted on a  small group of men scheduled to undergo a prostatectomy, the procedure for  removing a cancerous prostate gland.
Those who drank several cups of  green tea daily a few weeks before the procedure had less prostate inflammation  and lower PSA (prostate specific antigen) readings, a protein marker for  prostate cancer, than those who didn’t.

How green tea helps reduce cancer risks and cardiovascular disease

It  appears that green tea polyphenols, the type of antioxidant flavanoids in green  tea, have extremely high antioxidant properties to help prevent clogged  arteries. That’s great for lowering cardiovascular  disease risks.
But they are more complex than most antioxidants as  they also exhibit pro-oxidant abilities that can induce apoptosis (programmed  cell death) in cancer cells. Cancer cells can’t handle oxygen. They survive by  fermenting glucose for metabolism instead.
So a cancer patient who eats  sugar is feeding his or her cancer cells and promoting their growth. That’s  something oncologists don’t warn their patients about.
Another  anti-cancer factor with green tea polyphenols is  their enzymatic effects that inhibit tumor blood vessel (angeogenic) growth  factors such as hepatocyte growth factor (HGF) and vascular endothelial growth  factor A (VEGF-A).
The type of polyphenols or flavanoids in green  tea are catechins. The most abundant catechin in green tea is epigallocatechin  gallate, commonly referred to as EGCG. And EGCG is considered the prime mover  for green tea’s health contributions.
Citizens of Japan have much lower  cancer rates than the U.S. despite having a higher percentage of cigarette  smokers. They drink high quality green tea  often. If you’re not up to heavy, high quality green tea drinking, then perhaps  green tea extract (GTE) supplements are right for you.
GTE supplements  have high concentrations of EGCG, and these are the supplements most often used  in trials with positive outcomes on cancer  patients. Of course, these mainstream medical trials are used on cancer patients  undergoing chemo or radiation or both.
What they usually discover is  their treatments are more efficacious with fewer side effects when green tea  extracts high in EGCG are used. That’s probably because it takes less poison to  kill the cancer cells when EGCG is introduced.

Wait, there’s more!

In addition to protecting against cancer and cardiovascular issues, green tea and greet tea extracts demonstrate anti-aging and promote longevity. Green tea or GTEs also promote blood sugar stability to help block the onset of adult onset diabetes (Type II diabetes).
Green  tea or GTEs may help the body metabolize energy from fat, making weight loss a  little easier. ECGC from green tea or green tea extracts have been observed to  boost the immune system by raising the number of the body’s T cells.
