Fluoride in all tea? or just Green and black?
I have read up alot of articals that go on to show the high levels of fluoride in green tea and black....but my question is that are the levels of fluoride in all tea or just some? cause most them say that tea leaves obtain more aluminum and fluoride from polution but im curious to know if there that high in other teas...

"Fluoride is known to help prevent dental cavities, but long-term ingestion of excessive amounts could cause bone problems. The average person ingests a very safe amount, 2 to 3 milligrams, daily through fluoridated drinking water, toothpaste and food. It would take ingesting about 20 milligrams a day over 10 or more years before posing a significant risk to bone health.
Whitford discovered that the fluoride concentration in black tea had long been underestimated when he began analyzing data from four patients with advanced skeletal fluorosis, a disease caused by excessive fluoride consumption and characterized by joint and bone pain and damage. While it is extremely rare in the United States, the common link between these four patients was their tea consumption -- each person drank 1 to 2 gallons of tea daily for the past 10 to 30 years."
"The new information shouldn't deter tea drinkers, as the beverage is safe and some teas even have health benefits, Whitford said. "The bottom line is to enjoy your favorite tea, but like everything else, drink it in moderation.""

Tea is an agricultural product, therefor the amount of any chemical in any tea is going to have a dependence on growing conditions. This means region, agricultural practices of the grower, water supply, soil make up and on and on. You also have to pay a lot of attention to what sort of water you are brewing the tea with.
A lot of the studies on the chemical composition of tea conducted in the USA are inaccurate in their extremely limited sampling. There are so many growing regions, so many farms, so many varieties of tea production method, that ripping open a bag labeled "green tea" is not going to tell you a whole lot of anything.
Your best bet is to buy close to source and from a provider that can provide you with a wealth of reliable and accurate information on any particular tea they sell. I am collecting and publishing a lot of data on this subject on my blog, stop by if you have any more questions. Good Luck!!Source(s): http://blog.maemawktea.com/

Camellia sinensis, the tea plant, produces what can be called "true teas".
Tea infusion readily releases Fluoride from tea leaves into water. As such, it is considered a significant dietary source of Fluoride (Lu, et al., 2004)
Tea plants accumulate fluoride in their leaves over time, so the oldest leaves contain the most fluoride, while the youngest contain the least.
Therefore, white tea (which is made from youngest leaves and buds) is your best bet if you’re trying to take in as little fluoride as possible.
Green tea that is made from older leaves,
oolong tea and black tea have more fluoride.
The highest amount of fluoride is found in brick tea, a lower quality tea made from the oldest tea leaves which are molded into the shape of a brick (thus its name).
Brick tea is the one to watch out for, as symptoms of fluorosis have been seen in Tibetan children and adults who drink large amounts of this kind of tea.
scientists (tested) several brands of instant tea available at grocery stores to determine the fluoride content in each.

It's much higher in the public water supply where they dump this hazardous waste into every ones drinking water.
