(NaturalNews) We've heard of the benefits of green tea but what about the evidence. The scientific community has shown strong interest in uncovering just what the benefits might be. Some have been cautious and say that there is limited long term evidence that green tea can combat certain diseases (1).

However, a recent study (reported on the ScienceDaily site) has found green tea improves the risk factors involved in heart disease (2). Drinking green tea improves the way cells in the lining of the circulatory system work. These cells are called endothelial and if they are not working well, then atherosclerosis may take hold. So the function of the endothelial cells are an indicator of cardiovascular risk.

A team of researchers at the Athens Medical School (Greece) led by Dr. Nikolaos Alexopoulos conducted a trail where volunteers had their brachial artery measured after consuming green tea, caffeine and hot water. The brachial artery was measured for the amount it had dilated. Dilation occurs when there is an increase in blood flow, and increased blood flow is good news.

Dilation was significant after drinking green tea, while it wasn't after drinking hot water or caffeine. It is known that black tea also impacts positively on endothelial function, but green tea is likely to have stronger antioxidants as it undergoes less oxidisation during processing.

What is positive for us is that antioxidants reverse the effect of oxidisation in the human body. This has to be good for many diseases. In fact another study mentioned in the ScienceDaily report (ibid) showed that damage to the endothelial cells caused by smoking can be reversed by green tea. Overall tea drinking is linked to reduced cardiovascular problems and mortality rates.

Another study, whose researchers were motivated by the value of green tea in oral hygiene, has looked at antibacterial activity in inhibiting bacteria (2). A bacteria called DNA gyrase locates a site or binds itself to a location. Drugs cannot be used to remove the bacteria because of serious side effects.

A team of researchers at the National Institute of Chemistry in Ljubljana (Slovenia) found that green tea catechins, in particular one known as EGCG (short for epigallocatechin), are able to target the DNA gyrase. The benefit of green tea, according to the lead researcher Roman Jerala, is its safety record as opposed to toxicity associated with drugs (3).

Further related research has found that green tea helps overcome the resistance of certain bacteria to antibiotics. Dr. Mervat Kassem from the Faculty of Pharmacy at Alexandria University in Egypt found that drinking green tea at the same time as taking the antibiotics improved the efficiency of the drugs to kill the bacteria including the strain of superbugs (4).

The antioxidant levels of green tea is reported to be a hundred times that of vitamin C and 25 times that of vitamin E. It is the catechins that are the most effective antioxidants in the tea. If these have the potency to reverse damage to cells, what other effects does green tea have? The cautions showed by some are valid; but they are a little behind given the conclusions of the recent research which has positive news about the benefits of green tea.

As everyone here knows, I am a coffee-aholic at night while working <- coffee

But, I also drink a great deal of green tea during the day, at least 5-6 mugs...rock on green tea!!!!

Hellooo

We don't sell the cold green tea drink here.. just the natural raw unsweetened stuff..

and it's YUCKY!... (to me)
I have persevered with it many times.. a little honey etc.. but the after taste is sooooooo bitter.. it's horrible.

I've been thinking of getting some of the Green tea tablets from the Health food shop instead.

My doctor asked me what I drink every day.
I toled him: two coffees. She was dissatisfied and aksed me if this is only what I drink per day.
I said yes and sometimes when is match on TV I drink two bottles of beer. I consoled herself a bit. :)
I need to drink more water (at least 1 L) and maybe I start drink green tea.

Crikey! yeah.. you need to drink more.

To be honest claayer you are better off with the tablets , to cut a long story short you would more or less have to mainline it to get enough of the active ingredients from the tea to count as a therapeutic dose , if H&B have a sale on you can get some great deals in there the dose per tab is normaly a little on the low side but at the discount they normally give you can afford to take them by the hand full

DON'T DRINK GREEN TEA!!!!!!!!



<<----------------------------------------------

OMG Ship How long do you have left ??

I brew my green tea in the coffee maker.

2 green tea bags
2 ginseng blend tea bags
10 cups of water

When tea is finished brewing, I pour it into a gallon tea pitcher, add
1/2 cup raw sugar, and fill with ice to make the gallon. Stir well to melt the ice.

In this way, I can drink it thoughout the day. It is refreshing and cold.
Tastes very good too! I do not care for plain green tea, it really lacks flavor. You may use any variation you like, using your favorite teas combined with the green tea.

Green tea is full of anti-oxitants, which destroy free radicals.
Free radicals are responsible for deforming cells and cell abnormalities.
Toxins taken into the body in many forms, create these free radicals.

The daily temps here have been 103 degrees F.
A cold glass of beneficial tea is very welcome!

Ohhh HealthyLiving...if you only knew about rabbits...

I bought some bottled green tea today... it tastes fairly good... all things considered.

I too use a coffee maker to brew green tea and black tea together.
Love the ice cold tea in the hot weather.

Check to see what they added to it

I drink green tea very very much maybe 1L per day and more and feel great

I always knew you were a right wing Republican, Healthy Living!!!
Shame on you!! Trying to disguise your true political affiliation!!


****Green tea is full of anti-oxitants, which destroy free radicals.


We all know it was the free radicals that founded this great nation!

It was the free radicals that sponsored the Boston Tea Party!

It was the free radicals that wrote possibly the most important document in the history of human-kind! The Declaration of Independence

It was the free radicals that established freedom of speech and freedom from religion!!


It was the free radicals, still at work, that ended the Vietnam War


And YOU want to destoy these FREE RADICALS! May God have mercy on your soul!!

I started drinking green tea regularly when my Dr. suggested it during a bout of laryngitis. I began to read up on it's overall health benefits and I feel great, having made it a part of my daily regimen!

Thanks for the info HL - I added green tea to my diet a year ago. I drink it 3x a day now - find it much more refreshing than reg tea. I still enjoy coffee, but have replaced that 2nd cup with the green tea now - have noticed a real diff in my energy levels and my dr said it increases metabolism - nice if you're trying to drop a few pounds. Thank you - am going to check out your website.
