Pu-erh Tea, What's The Verdict?

    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:

    http://pubs.sciepub.com/jfnr/2/12/22/index.html

    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?

    It can but a proper manufactured pu erh tea can also contain penicillin and other beneficial microorganisms. Which makes it Peaty too.

    I am very interested in it if it could potentially mean a natural daily source of caffeine, theanine and penicillin, a pretty epic combination in one drink.

    Tea is not ideal beverage in peat view.he said pu erh is ok! But he admires coffee!

    Especially if you drink lots of tea ,it becomes a bit irritating to digestive system. Those tannines ,phenoles.

    Black tea is a bit estrogenic, green tea a bit anti thyroid.

    I loved tea because of theanine/manganese ,but my digestion is more agree with coffee , apparently.

    As long as tea is enjoyable for me i drink it, at least to get some manganese if i i dont have any other manganese rich food in a period.


    Also i want add that adding a little bit lemon juice or dried lemon or milk to my tea really offsets some of bad effects it has on my digestion.

    Good question ,i wondering why ray suggested this type of fermented tea.

    Chris masterjohn is his podcast also mentioned fermented food often is a cause of allergies.


    Good points and questions @Aleeri

    Seems to contain the Candida strain. Another fermented beverage that usually contains it is Kombucha.

    Dr. Peat says this all the time. But I'm not sure I have heard of anyone with an allergy to tea. Puerhh is moldy. I've bought it, I've used a lot of it. I no longer consume it. I just think it is suspect. And I don't drink much tea anymore anyway.

    Thank you for mentioning it as I have this allergy. I wonder why it's not widely known to avoid it in people with this allergy or if it causes serious reactions.
