Hi,
Green tea is on the cover of the magazine this month. What is the reality of the objections laid on Green tea due to its higher fluoride content for e.g look at the criticism found here:
Best regards

- The new green tea products, Mega Green Tea Capsules contain:
# 00753 (lightly Caffeinated) has a fluoride content of 26.1 parts per million.
# 00754 (Decaffeinated) has a fluoride content of 20.3 parts per million.
Since people are usually consuming just one of these capsules per day, it doesn't amount to a lot of fluoride. Concerning drinking the tea, there is something called brick tea fluorosis that occurs in some parts of China from drinking brick tea that is high in fluoride. This doesn't occur in other regions in which the residents have been drinking tea for thousands of years. The Guizhu province especially produces tea with a higher fluoride content than other regions. - Moderator Post Edited By Moderator (DDye) : 1/4/2005 4:54:52 PM GMT | | Back to Top | | |

alfax said... I DRINK AN AVERAGE 4-5 CUPS OF GREEN TEA A DAY. CAN THESE CAUSE A DANGEROUS INTAKE OF FLUORIDE? Here is what Linus Pauling Institute has to say about it:
(down a bit on the page).
I would guess that if you are really worried, then you should simply
stop consuming it until you get a satisfactory answer directly from
the Brand you consume (Or send it in to a lab for analysis).
I think Mercola has some good information, but sometimes tends to be
more on the alarmist side.
(BTW I drink 1-3 cups brewed fairly weakly each day and am not too concerned) | | Back to Top | | |

I read that the 3 most toxic substances to the body were in order lead, fluoride and mercury. (I found it on Google). I also read that fluoride was originally a byproduct of aluminum manufacturing and considered a hazardous substance until someone figured out how to pawn it off on the unsuspecting public. Can someone confirm this?
Incidentally, people in Okinawa don't actually drink green tea- they drink Jasmine tea (The Okinawa Program by Dr. Bradley J. Wiicox M.D.). A breif quote from the book on page 161:
"One of the more surprising findings from our studies of the Okinawan diet was the high consumption of jasmine tea, especially among the centenarian poulation. Jasmine tea is the most popular beverage of the elders, who rarely drink plain Japanese green tea."
I personally have given up green tea until I find evidence to the contrary. I inquired about the possible dangers of fluoride in the green tea from LEF weeks ago but have not heard back from them as yet.
- Jasmine tea is green tea to which jasmine flowers have been added. We have posted to the forum the amounts of fluoride in Life Extension's newest green tea extract capsules which are 26.1 and 20.3 (in the decaffeinated formula) parts per million. This is not much fluoride. If you will send me a private message concerning who you addressed your correspondence to that has not yet answered you, will check on it for you. - Moderator

I looked up the list of toxic substances and actually arsenic is first, followed by FLUORIDE and then lead, etc. I know arsenic is hazardous at 1 part/million. What about fluoride? What's the number? 28 and 20 parts /million doesn't seem low to me.
- Here is a paragraph from the Linus Pauling Institute's site:
"The fluoride content of most foods is low (less than 0.05 mg/100 grams). Rich sources of fluoride include tea, which concentrates fluoride in its leaves, and marine fish that are consumed with their bones (e.g., sardines). Foods made with mechanically separated (boned) chicken, such as canned meats, hot dogs, and infant foods also add fluoride to the diet (21). Foods generally contribute only 0.3-0.6 mg of the daily intake of fluoride. An adult male residing in a community with fluoridated water has an intake range from 1-3 mg/day."
If you are using the Mega Green Tea Extract nondecaffeinated version, multiply .0000261 (which is 26.1 over 1 million) times the 725 milligrams of green tea extract in item #00753, you have .0189225 milligrams which equals 18.9225 micrograms fluoride in one capsule. - Moderator Post Edited By Moderator (DDye) : 2/16/2005 4:34:30 PM (GMT-5) | | Back to Top | | |

Another thing to keep in mind is that tea has been consumed for thousands of years, and all the facts seem to suggest that it helps prevent health problems, and does not contribute to them. Please see the following link:
http://www.nbc4i.com/health/1451480/detail.html
On the other hand, perhaps the chemical compounds in tea neutralize any negative effects of fluoride, and tea might possibly be improved by removing the fluoride.
The article at the following link suggests that instant tea may have concentrations of fluoride that are too high, and that brewed tea has comparable concentrations of Fluoride. A 52 year old woman who drank 1 to 2 gallons of instant tea a day (mixed at double strength) her entire adult life, obtained a chronic backache. It was then determined she had fluorosis after she disclosed her tea drinking habits. However, the pains went away after she quite drinking tea for a few years.

In the article at the link directly above, Michael Whyte, a professor at Washington University's School of Medicine, stated that two or three cups of tea a day should not be a problem. However, based on what I read in the article, if you are drinking two quarts or more per day, you may be getting too much fluoride from the tea.
In addition to not drinking more than three cups of tea per day, I think if you brewed the tea with distilled water, and drank distilled water rather than tap, that would be helpful in limiting your fluoride consumption. Also, using tooth paste without fluoride will help.
Here are some links to some variations on the same or similar articles:

You can do a www.google.com "news search" for the latest news on the topic.
You can also get google news alerts on fluoride here:
http://www.google.com/alerts?q=fluoride&hl=en
NOTE: I have been drinking nothing but distilled water since I was 15 (I am 37 now) and I have only had 1 small cavity my whole life, and that was when I was drinking tap water with fluoride as a kid !!
I am going to keep drinking 1 to 3 cups of tea per day, brewed with distilled water.
Hope this helps.

I use only toothpaste without fluoride, drink certain bottled water and shudder when I think of the fluoride in my bath water. I've read that it interferes with thyroid function, could this be why so many people now have temps under the 98.6 mark? And, when you stop to think about it maybe fluoride is a leading cause of obesity as the thyroid regulates your metabolism and body growth. Just a thought. | | Back to Top | | |
