Green tea could help protect against the damage caused by heart attacks and strokes, researchers suggest.

A chemical found in the tea, which has been drunk for over 4,000 years, has been shown to reduce the amount of cell death which follows such trauma.

Cell death leads to tissue death and even organ failure.

Experts from the UK's Institute of Child Health carried out the study, published in the journal of the Federation of Experimental Biology.

Green tea was frequently used in the past as fluid supply for patients suffering from infectious diseases, but recently researchers have begun to scientifically determine the health benefits of green tea.

Tea is very high in fluoride content. What about fluoride role in this respect?
 
From the same source:
He said more research would have to be carried out before patients could be advised to drink green tea after a heart attack or stroke.

"But hopefully we will one day be able to tell patients who are susceptible to heart disease that they can drink green tea for its therapeutic benefits."

Belinda Linden, head of medical information at the British Heart Foundation said: "Green tea has, in the past, been associated with a reduced risk of coronary artery disease, with claims that its high antioxidant properties may cut the amount of cholesterol in the artery wall.

"The results suggest that there may be other ways that green tea could protect the heart, but larger controlled studies would be needed to confirm this benefit."

This could be good news indeed, but further SCIENTIFIC research is required to ensure it really IS good news. Don't you agree?

Normal drinking water has easily measurable flouride content. What about normal drinking water role in this respect?

A better question would be is that chinese green tea or japanese green tea?

Actually all tea, whether green, orange (oolong), or black, comes from the same plant. The difference is in the processing. Natural enzymes begin transforming the cell contents as soon as the tea is picked.

Chinese green tea is produced with a very short withering period followed by rapid heating to deactivate the enzymes then rolling and drying. Japanese green tea is steamed immediately to deactivate the enzymes, then rolled and dried. It is thus slightly "greener" than the chinese version.

Oolong tea is lightly rolled first and allowed to ferment for a few hours before the enzymes are deactivated. Black tea is aggressively rolled for up to an hour and allowed to ferment for 4 hours or more before the enzymes are deactivated...

Kumar is correct about the fluoride content of tea being quite high ...higher in mature plants than younger ones in fact.
However: I seriously doubt it is the fluorides in tea which are responsible for these findings. Almost every published study and comment on MedLine states that the fluoride content in tea is responsible for engaging its traditional dental cavity fighting ability.

On the other hand teas, green, black or otherwise, contain up to 4 different kind of polyphenols or polyphenol catechins, potent antixoidants found also in a number of exotic juices and in red wine and even dark chocolate. The best studied of these substances seems to be epicatechin gallate. or
epigallocatechin-3-gallate

There are 23 pages of citations in MedLine on tea's polyphenol content and its value. I would have to say, like beverages mentioned elsewhere, it is early yet but polyphenols seem to be a provocative benefit derived from a variety of sources.

enter green tea polyphenols

into the search engine at:

entering green tea alone into Medline produces over 80 pages of published studies.

materia3,

Can you compare effects of green tea somewhat as metioned on this link.
Click to expand...

Nope. I am afraid I think homeopathy and the theories on this website regarding so-called fluoride imbalance are nonsense.
About the only accurate remark is that fluoride protects bone and tooth enamel.

These disorders

Piles, hemorrhoids
Varicose or Enlarged Veins
Hardened Glands
Organ Displacements
Weakened Abdominal Walls
Hemorrhages of Organs or Tissues

have well established causations and there is no proof calc.fluor imbalance is one of them. I already pointed out that any cardiovascular benefit of green, black, even red and oolong teas is due to the presence of polyphenol antioxidants.
 
Both are also said to be related to anti tumor effect. Btw, I am looking for some other concept. Can it be possible that two are complementary or antidotal to each other at 'organic' & 'inorganic' level?

In some studies, fluoride is related to heart/CVs diseases.

P.S. One very important question;

Whether tea water made from green tea will still contain similar amount of both?

What about these disorders, Are their basic reasoning/causes are somewhat less understood?

Following are some indications of composition & thier role;-

Composition of the green tea leaf: ( % of dried leaf )
Polyphenols 37%
Carbohydrates 25%
Caffeine 3.5%
Potein 15%
Amino acids 4%
Lignin 6.5%
Organic acids 1.5%
Lipids 2%
Ash 5%
Chlorophyll 0.5%

Just a thought; In view of Calc.Fluor. & EGCG indications, it appears that EGCG help in reversing fluoride effects of causing CV diseases(opposite effect by potentised remedies) due to its accumulation. It also made me to know some logic of organic & inorganic body's substances role. Specific organic & inorganic body substances to any part of body can act as compensating, antidotal or balancing substance to each other---or organic substance can behave to balance any imbalanced inorganic mineral. That organic mineral if used or extracted & used can act for balancing related imbalkanced inorganic mineral. Accordingly, EGCG might be doing for fluoride. But it can be important to understand 'fluoride in tea water & EGCG & fluoride balance for getting the benefits.
 
Tea is very high in fluoride content. Fluoride in tea is much higher than the Maximum Contaminant Level (MCL) set for fluoride in drinking water.

Tea leaves accumulate more fluoride (from pollution of soil and air) than any other edible plant (1,2,3). Fluoride content in tea has risen dramatically over the last 20 years, as has tea consumption (4).

While in 1976 a Belgian analysis showed content of between 50 and 125 ppm fluoride in 15 varieties of tea (3), a Polish study in 1995 found fluoride content of up to 340 ppm in 16 varieties of black tea (5). A major Canadian study published in 1995 reports average fluoride content in tea to be 4.57 mg/l in the 1980's (6).

A website by a pro-fluoridation infant medical group lists a cup of black tea to contain 7.8 mgs of fluoride (7), which is roughly the same amount as if one were to drink 7.8 litres of water in an area fluoridated at 1ppm. It is well known that fluoride in tea gets absorbed by the body similarly as the fluoride in drinking water (1,8).

Does it mean something?

zep, look at one advt. for green tea expract;

"The most potent GREEN TEA LIQUID EXTRACT
2 fluid oz - 60 ml - 60 servings @ 1 ml/30 drops
Highest Polyphenol content * Organic * Alcohol Free * Fluoride & Aluminum free * Caffeine Free * Standardized * Pleasant Tasting "

Yes. It means that there is a high flouride content in tea.

Quote was for full article as link was given.

While there can be no doubt as to the beneficial effects of individual antioxidants found in green tea, the same cannot be said about green tea as a beverage. Existing studies tend to concentrate on active ingredients of green tea, such as epigallocatechin gallate (EGCG), a compound that belongs to a family of antioxidants known as polyphenols. EGCG and other polyphenols are constituents of tea - especially of green tea.

However, no studies exist investigating the effects of fluorides on these anti-oxidants. Existing studies involving other antioxidants and fluoride compounds give evidence that fluorides can adversely affect the action of antioxidants(27). Thus, while isolated antioxidants may slow down the development of some forms of cancer in experimental studies, their effect may be annihilated in their complex natural environment (as a sum of the action of all the substances present).

But probably, you may not be able to afford my fees for giving/sending the information, specifically on e.mail. ;)

This is an excellent reason why people should not go overboard and rely on unregulated natural remedies and leave it to competent scientists to identify, isolate, test (both for benefits and risks) and determine dosages for active ingredients. While this paragraph is evidently pushing a theory (without foundation -- which they admit: "no studies exist .....") upon which a commerecial product is based,it makes sense.

However this does not mean its true and it does not mean the product they are pushing is either safe or effective.

In fact in perusing the MedLine cites I recall there were a few, for example, where some doses of polyphenol caused liver damage in mouse studies. This is why it is early yet in exploiting the benefits of polyphenols as well as gauging the risks and under what circumstances or dosages they are apt to increase.
