Drinking green tea with starchy food may help lower blood sugar spikes
In continuation on my update on green tea
Mice
fed an antioxidant found in green tea
epigallocatechin-3-gallate, or EGCG and corn starch had a significant
reduction in increase in their blood sugar blood glucose levels compared to
mice that were not fed the compound, according to Joshua Lambert, assistant
professor of food science in agricultural sciences.
The dose of EGCG fed
to the mice was equivalent to about one and a half cups of green tea for a
human. Lambert, who worked with Sarah C. Forester, postdoctoral fellow, and
Yeyi Gu, graduate student,
both in food science, said EGCG was most effective when the compound was fed to
the mice simultaneously with corn starch. For humans, this may mean that green
tea could help them control the typical blood sugar increases that are brought
on when they eat starchy foods, like breads and bagels that are often a part of
typical breakfasts.
"The spike in blood glucose level is about 50 percent lower than the increase in the blood glucose level of mice that were not fed EGCG," Lambert said.

Green tea found to reduce rate of some GI cancers
In continuation of my update on green tea.
We know that, Tea contains polyphenols or natural chemicals that include catechins like EGCG and ECG. Catechins have antioxidant properties and may inhibit cancer by reducing DNA damage and blocking tumor cell growth and invasion.
Now researchers have found that regular tea consumption, defined as tea consumption at least three times a week for more than six months, was associated with a 17 percent reduced risk of all digestive cancers combined. A further reduction in risk was found to be associated with a increased level of tea drinking. Specifically, those who consumed about two to three cups per day (at least 150 grams of tea per month) had a 21 percent reduced risk of digestive system cancers.
For all digestive system cancers combined, the risk was reduced by 27 percent among women who had been drinking tea regularly for at least 20 years," said Nechuta. "For colorectal cancer, risk was reduced by 29 percent among the long-term tea drinkers. These results suggest long-term cumulative exposure may be particularly important."

GEN | News Highlights:Green Tea and Gold Nanoparticles Destroy Prostate Tumors
In continuation of my update on green tea
Scientists report on the development of a radioactive gold nanoparticle for prostate cancer therapy that they claim is far less toxic to normal tissues than traditional radiation therapy and results in massive reduction in tumor volume and increased survival in experimental mice after just one dose. The nanoparticles, derived from the Au-198 isotope, incorporate an extract from green tea known as epigallocatechin-gallate (EGCg), which effectively latches the nanoparticles onto the prostate tumor cells and facilitates their internalization.

Green tea shows promise against two types of tumors, HHS
In continuation of my update on green tea
Researchers lead by Dr. Thomas Smith at The Donald Danforth Plant Science Center
and his colleagues at The Children’s Hospital of Philadelphia, have found that a compound found in green tea shows
great promise for the development of drugs to treat two types of tumors
and a deadly congenital disease.
Dr. Smith and his colleagues discovered
that two compounds found naturally in green tea are able to compensate
for this genetic disorder by turning off GDH in isolated and when the
green tea compounds were administered orally. The Smith lab also used
X-ray crystallography to determine the atomic structure of these green
tea compounds bound to the enzyme. With this atomic information, they
hope to be able to modify these natural compounds to design and develop
better drugs.
Interestingly, two other research groups
have validated and extended these findings to demonstrate that blocking
GDH with green tea is very effective at killing two different kinds of
tumors; glioblastomas, an aggressive type of brain tumor, and tuberous
sclerosis complex disorder, a genetic disease that causes non-malignant
tumors to grow on a number of organs.

Polyphenols in red wine and green tea halt prostate cancer growth, study suggests
In continuation of my update on Green Tea and EGCG........
Polyphenols in red wine and green tea halt prostate cancer growth, study suggests
"The profound impact that the antioxidants in red wine and green tea have on our bodies is more than anyone would have dreamt just 25 years ago," Weissmann added. "As long as they are taken in moderation, all signs show that red wine and green tea may be ranked among the most potent 'health foods' we know." ....

Green tea might help to treat Uterine Fibroids....
We have seen many research groups trying to explore the usefulness of green tea for reduction in heart disease (bad cholesterol), increase in metabolic rate (fat oxidization) prevention of Alzheimer’s or Parkinson’s diseases, lowering incidence of cancers and weight reduction.
Now researchers from Meharry Medical College in Nashville, Tenn lead Dr. Ayman Al-Hendy , have found that green tea extract shows promise as a treatment for uterine fibroids. The key ingredient responsible for this activity is "epigallocatechin gallate (EGCG)". The researchers investigated the effect of epigallocatechin gallate on rat leiomyoma (ELT3) cells in vitro and in a nude mice model. ELT3 cells were treated with various concentrations of EGCG. Cell proliferation, proliferation cell nuclear antigen (PCNA), and cyclin-dependent kinase 4 (Cdk4) protein levels were evaluated. As per the claim by the researchers, EGCG significantly decreased PCNA and Cdk4 protein levels. The authotrs conclude that EGCG effectively inhibits proliferation and induces apoptosis in rat ELT3 uterine leiomyoma cells in vitro and in vivo.

Gren tea for new type of H1N1 Flu ......
In continuatation of my update on Epigallocatechin gallate (EGCg), I find this info something different and interesting too. We are aware about the antioxidant and anticancer activities of this compound, but now researchers from Central Research Institute of ITO EN, Ltd., & School of Pharmaceutical Sciences, University of Shizuoka have found the same compound to inhibits flu infection. As per the researchers claim, the compound had an inhibitory effect against three types of influenza viruses, including the swine-origin H1N1 virus that caused pandemic flu in 2009, and that its effect did not depend on the type of virus. These findings once again suggest that green tea is effective in preventing flu.
Gargling with green tea has already proved to prevent the onset of seasonal flu. It has become clear that catechin, a major type of polyphenol in green tea, plays a major role in prevention of flu infection, and that, among different types of catechin, EGCg displays the strongest antiviral activity. More interestingly, the researchers have conducted examinations to see if EGCg also shows antiviral activity against the new type of H1N1 virus, regardless of viral subtypes.
Solutions containing three types of viruses including the H1N1 virus were mixed with EGCg extracted from green tea. The mixture was added to cultured cells, which were thus infected. The cells were incubated for a set period of time, and the number of infected cells was counted. The concentration of EGCg at which virus infection was inhibited to 50% of the level of infection without EGCg was calculated.
The experiments showed that EGCg prevented flu virus infections at lower concentrations than Amantadine (a drug used to prevent and treat flu). A typical concentration of EGCg in green tea infused from a teapot is reported as 5,000-7,000 micromoles/L. Therefore, these results indicate that green tea diluted 1,000-fold or more is effective to halve infections by three types of viruses, including H1N1.

Combination of EGCG & DAPH-12 - a treatment for brain disorders ?
![](http://1.bp.blogspot.com/_PiEbciaMtBE/SxkL77-q-6I/AAAAAAAAAVk/eXvZ6HfP0LE/s320/Epigallocatechin+gallate.png)
To date, researchers have had no success in destroying plaques in the human brain and only minimal success in the laboratory. One reason for these difficulties in finding compounds that can dissolve amyloids is their immense stability and their complex composition.
Yet, Dr. Duennwald ( Boston Biomedical Research Institute , BBRI) and co workers from Pennsylvania School of Medicine, experienced success in previous studies when he exposed amyloids in living yeast cells to EGCG (see the above structure). Furthermore, he and his collaborators also found before that DAPH-12, (see below structure) too, inhibits amyloid production in yeast.
Epigallocatechin gallate, also known as Epigallocatechin 3-gallate, is the ester of epigallocatechin and gallic acid and a type of catechin. EGCG is the most abundant catechin in most notably tea, among other plants, and is also a potent antioxidant and that may have therapeutic properties for many disorders including cancer. It is found in green tea, but not black tea, as EGCG is converted into thearubigins in black teas. EGCG can be found in many supplements.
These findings are significant because it is the first time a combination of specific chemicals (EGCG & DAPH-12) has successfully destroyed diverse forms of amyloids at the same time.
Though the detailed mechanism is still to be established, its a good achievement and hope this combinatorial therapy will help those sufferings from Alzheimer's and other degenerative diseases (Huntington's, and Parkinson's) in the days to come.....
