In terms of Peat friendly foods, tea has always seemed to be a problematic one that is worshipped in the world of natural health, but according to Peat values looks to have a bunch of negatives such as fluoride and estrogenic flavanoids.
But what about Pu -erh tea? Which is basically a fermented black tea.
I know Peat said the following about it in email exchanges but did not elaborate further as to why:
EGCG, total catechins and the alike seems to be broken down in Pu erh tea from the fermentation, basically forming theabrownin: Effects of enzymatic action on the formation of theabrownin during solid state fermentation of Pu-erh tea. - PubMed - NCBI
Yet retains the caffeine: Factors affecting the levels of tea polyphenols and caffeine in tea leaves. - PubMed - NCBI
There are some interesting properties to Pu erh such as inhibiting nitric oxide:
Pu-erh Tea Reduces Nitric Oxide Levels in Rats by Inhibiting Inducible Nitric Oxide Synthase Expression through Toll-Like Receptor 4
Protective effects of pu-erh tea on LDL oxidation and nitric oxide generation in macrophage cells - ScienceDirect
Beneficial effects on gastric function and bowel movement:
Component analysis of Pu-erh and its anti-constipation effects
Protective effect of Pu-erh tea extracts against ethanol-induced gastric mucosal damage in rats
A lipid-lowering effect in hyperlipidemic rats:
Effects of theabrownin from pu-erh tea on the metabolism of serum lipids in rats: mechanism of action. - PubMed - NCBI

Above is just a small assortment of what I read today. There is also a whole bunch of anti-cancer research but what I am more interested in discussing is do you guys think the benefits outweigh the negatives of this tea?
It does seem to contain amounts of kaempferol and quercetin still which is considered estrogenic here right?
https://europepmc.org/abstract/med/23947136
Hesperidin and naringenin are found in orange juice too which is consumed a ton here so why are people not weary of them too same as quercetin for example?
Also, cacao contains quercetin but is considered a Peaty food, recommended since it inhibits iron same as coffee but is also a good magnesium and saturated fat source.
Do the estrogenic flavanoids really matter that much or is flouride the only real threat with Pu erh tea?

The addition of lemon or milk to tea reduces the reactivity of the tannins. In recent years, the tea industry has very commonly been adulterating the product. Pu erh is one that still seems to be o.k.

For example, the flavonoids, naringenin, quercetin and kaempherol (kaempherol is an antioxidant, a phytoestrogen, and a mutagen) modify the metabolism of estradiol, causing increased bioavailability of both estrone and estradiol. (W. Schubert, et al., "Inhibition of 17-beta-estradiol metabolism by grapefruit juice in ovariectomized women," Maturitas (Ireland) 30(2-3), 155-163, 1994.)
