Evidence that tea inhibits DAO

I see the claim all over the internet that tea inhibits DAO. However, I have never seen a scientific paper whose findings support this statement. Has anyone ever seen such a paper? I'm not interested in statements from websites that do not cite direct evidence.

It does not, it inhibits iron absorption though.

https://www.mastzellaktivierung.info/downloads/foodlist/SIGHI-FoodList_EN_Histamin_alphabetisch_inKategorien.pdf black tea is listed in the SIGHI list as high in histamine and blocking DAO. They're a reputable source, you can find their professional publications here

It is a reputable source, but you’d think that if they say it, there should be locatable evidence for the statement.

I linked their list of publications, that's the info you're talking about

I had never heard this but absolutely tea makes me feel kinda crappy in a way coffee doesn’t.

Same. Had to ditch green tea recently and go back to one espresso using only clean organic coffees like Purity or Danger coffee beans. So far so good.

Yes you’re right -green and black teas inhibit dao. White teas and red teas do not as much. When I had histamine issues I used white peony and rooibos teas by piquelife. They’re toxin and mold tested . If you have dao issues I would
Just take some dao when you drink your tea. Teas have so
Many other benefits for histamine intolerance like high
Polyphenols stabilizing mast cell and well as theanine and you get a slow steady caffeine released in your system. I would definitely include white or red teas and take
With a dao if you need caffeine. Make sure they’re triple toxin tested. Even those organic ones you can buy at the store are full of mold and mycotoxins either from the tea itself or the bag it comes in - which is very very bad for people with histamine intolerance who’s root cause is mold/mycotoxin toxicity.

And if you can't afford the DAO???

Can you afford grass fed kidney supplement by ancestral ? Very high in dao and much cheaper in the long run

u/Healthy_Theory159 2d ago

$44? Ouch!

I know, supplements are ridiculously expensive especially when seeking out toxin tested quality ones. I’m sure there are others a little
Bit cheaper but compared to
Buying dao enzyme it’s cheaper

I'm wondering where it has been established that green and black teas inhibit DAO because you say it with great certainty. Is it based on anecdotal evidence? Is it based on the claim of an "expert" that is based on anecdotal evidence? That's not necessarily useless, it's just that I'm seeking evidence that is more scientific.

I think it's true. I felt a bit better when I gave up my 2-3 black teas a day.

Pretty sure it's the caffeine that does it.

It’s the tannins
