Green Tea: Health Articles
D
atabase - Green tea research has shown it has an effect on variety of health conditions. The ability to lower blood sugar, chelate iron and control the production of nitric oxide are all especially
important. This ancient beverage seems custom-made to protect health and delay aging. To find how green tea benefits different organs and conditions click a specific topic from our article database below:

New research from Japan: Green tea fights pneumonia in Women


Date: 11-09-2009
Yet another study of the Ohsaki data by scientists at the Tohoku University Graduate School of Medicine, published in the September edition of the American Journal of Clinical Nutrition, found a strong link between drinking green tea and protection against pneumonia in women. The researchers noted in their paper that experimental and animal studies have previously shown that catechins, antioxidant phytochemicals found abundantly in green tea, are active against infectious agents -- so that could be a possible explanation for green tea's apparent pneumonia-fighting ability. They excluded any research participants who were missing information on their green tea consumption or who had reported a history of cancer, heart attack or stroke. In all, the scientists followed the research subjects' health for over 12 years. The results showed, at least for women, a dramatic reduction in the risk of pneumonia for green tea drinkers. Once again, drinking five or more cups a day appeared to offer the most benefit. All of the research is based on findings from the huge Ohsaki National Health Insurance Cohort Study in Japan which involved 41,761 Japanese adults between 40 and 79 years of age. None of the research subjects had a history of cancer when the study started and their diets, along with other lifestyle factors and any health problems they developed, were followed for about ten years.



UMC to enroll subjects for green tea-HPV study


Date: 10-26-2009
The University Medical Center in Arizona is calling for about 156 test subjects in its study to see if green tea extract could be used to clear the human papilloma virus, the virus that can lead to cervical cancer in women. Previous experiments have shown that green tea extract helps clear up cervical lesions created by the virus. Now scientists want to see how effective it is on the virus itself. The scientists are focusing their attention on Polyphenon E, a chemical present in green tea. This is the same green tea extract that other studies have shown may slow prostate cancer in men. Researchers plan to enroll 156 patients with HPV or abnormal pap smears in a four-week study known as a double-blind placebo controlled experiment. Half of the women will receive the Polyphenon E and the other half with receive a placebo. Neither the researchers nor the subjects will know who is receiving which treatment until the study is over. Over the four-month period of the study, test subjects will make six study visits to track the progress of the HPV. They will be compensated $250 at the end of the study. Since it’s know that a person’s immune system can clear up HPV on its own, the objective of the study is to see if the more women who receive the Polyphenon E clear the HPV than those receiving the placebo. Other studies in the past decade have shown that green tea is a boost to the immune system. It may prove to boost the immune system well enough to clear HPV.



Virus Replication & Green Tea


Date: 01-01-2003
Recent studies suggest that green tea catechins may inhibit the HIV virus replication, and various other viruses. A study done at the Laboratory of Viral Oncology in Nagoya, Japan, discovered that two catechins found in green tea, epigallocatechin gallate and epicatechin gallate, were able to differentially inhibit the enzymes used by the HIV virus for replication: reverse transcriptase and various DNA and RNA polymerases. A more recent Chinese study at the Institute of Medical Biotechnology in Beijing found that green tea catechins in general could inhibit the reverse transcriptase or polymerases of several types of viruses, including HIV-1 and herpes simplex 1. Various polymeric oxidation products of polyphenols have also been found to inhibit the herpes simplex virus. It seems that flavonoids in general ought to be more thoroughly researched for their ability to inhibit the replication of viruses and keep them in a state of latency.
