I prefer Oolong tea and Green tea, but drink some Black tea as well from time to time.

Chamomile tea is good by me in on a couple fronts. It helps promote sleep and it's also a natural aromatase inhibitor.(apigenin)

The catechins of Green tea are also supposedly an aromatase inhibitor as well. :2cents

Very hard to avoid fluoride and there are no stats on tea brands and locations for fluoride content. Would be nice if someone published that info.

Very hard to avoid fluoride...

With so many types of tea, it is hard to know the full spectrum. The studies I've seen note fluoride levels within a factor of ten between high and low tea samples, with black tea being on the high end. So frequent drinking of any leaf in the Camellia sinensis (black, green, white, etc.) line may accumulate fluoride. For instance:

Some info on fluoride content of tea products is gathered here:

But it's also worse than that, with widespread LEAD and some ALUMINUM contamination in brewed teas among 30 Camellia sinensis black, green, white, and oolong teas:

"All brewed teas contained lead with 73% of teas brewed for 3 minutes and 83% brewed for 15 minutes having lead levels considered unsafe for consumption during pregnancy and lactation. Aluminum levels were above recommended guidelines in 20% of brewed teas."

There are studies. The ones I've read tend to show high fluoride, aluminium and other nasties for all teas. Doesn't matter the brand, organic or not, Green or White or Black... In particular it did not seem like Green was safer than Black for fluoride. The only way out are some young leaves from some non-polluted area (so, you can exclude the main countries where commercial tea usually comes from). If that exists, you wouldn't find that at the grocery or high street tea shop, but possibly online and not cheap.

How about dumping some calcium acetate into tea to bind fluoride? I got the tip from an internet forum where people were trying to remove fluoride from tap water, one poster said reverse osmosis was disappointing because it removes a bit but you could have a lot left, so might as well use calcium acetate in your drinks.

There's not just fluoride to be careful of but the many estrogenic polyphenols.

A safe green tea is almost an oxymoron. Stick to lightly caffeinated coffee (or diluted coffee) if you enjoy sipping on a warm drink.

People have been drinking green tea for millennia there is nothing wrong with it at all if you stick with loose leaf or real matcha ( not that proccesed stuff that has been used due to matchas popularity lately)

It's time to move beyond the 'so-and-so has been drinking/eating this for centuries so it must be healthy/OK/whatever' thinking.

Green Tea and its Fluoride Content, a major Health Hazard

Geoff Pain

Feb 2018

Abstract
Green Tea is promoted as a healthy beverage yet few consumers are aware of the health
risks caused by its Aluminium, Fluoride, Fluoroacetate, Heavy Metal, Oxalate and
Polyphenol content.
Keywords: Aluminium, Anaemia, Asthma, Bai-mieng, Brick Tea, Camellia sinensis, Cancer,
Cardiovascular Disease, Chemical Castration, Extract, Fluoride, Fluoroacetate, Fluorosis,

Introduction
"Fluoride is a Schedule 6 Poison. The acute lethal dose of Fluoride for humans is less than 5
milligram of Fluoride per kilogram of body weight. The World Health Organization (WHO)
states that Fluoride is more toxic than Lead and slightly less toxic than Arsenic.
Fluoride is a bio-accumulative, endocrine disruptor that has no nutritional value [Pain 2016a].
Fluoride is a teratogen [Fedrick 1974, Correa 2000, Wang 2004, Zielinsky 2013].
Therefore all allegations that there is an “adequate intake”, “optimal intake” or “tolerable
upper intake” of Fluoride are completely false and misleading.
The question of what constitutes a “safe” dose of this bio-accumulative poison has been
addressed using the criterion of predicted reduction in the IQ of exposed children and is
estimated to be 0.0010 mg Fluoride/kg-day [Hirzy 2016]. Clearly this implies that the
commitment expected to be made by public health authorities should be to the ALARA
principle, i.e. keeping exposure reduced to As Low as Reasonably Achievable.
Tea (Camellia sinensis) is a major source of Fluoride in the diet throughout the world.
Despite this, the Australian government, through its agency the National Health and Medical
Research Council (NHMRC), deliberately excluded in its 2017 review on the health effects of
water fluoridation, twenty-eight (28) peer-reviewed scientific papers relevant to the Fluoride
content and adverse health impacts of drinking tea [Jack 2016].
The focus of this review is Fluoride content of Green Tea and its derivative products such as
Brick Tea formed by compression, Kombucha formed by fermentation and instant packaged
Green Teas. Tea also contains other toxins not covered in any detail here, such as
Aluminium, heavy metals and Oxalate [Simpson 2001].
The toxicity risk of Green Tea has been evaluated [Sarma 2008, Zerabruk 2010,
Janiszewska 2013, Atasoy 2016]. Human toxicity of Kombucha has been reported [Ernst
2003, Sunghee Kole 2009] and its Fluoride analyses reported [Kumar 2008].
As Green Tea, Black Tea and White Tea all come from the same plant, the health impacts of
Fluoride ingestion from Green Tea discussed here are generally applicable."
