Is pu-erh tea keto-compatible?

What to know about pu-erh tea

Pu-erh is the only tea that is properly fermented rather than merely oxidised. Leaves from Yunnan are pressed into cakes or bricks and worked on by microbes, either slowly over years (raw sheng) or by a forced pile fermentation that compresses the process into weeks (ripe shou). Because every other microbially aged food on this list carries an amine warning, the reasonable assumption is that pu-erh does too. The grades say otherwise: pu-erh is rated clean on histamine, histamine liberation and tyramine, and clean again on salicylate, oxalate, FODMAPs, gluten, nickel and sulfite. Pu-erh is the one tea where trace histamine and tyramine are detectable at all in laboratory work, but the quantities reported are small next to genuinely amine-heavy foods like aged cheese or cured sausage. That leaves two honest caveats. Caffeine is graded moderate and young sheng is often stronger than the dark shou people picture. And the fermentation gives it a slight edge over plain green tea for a very sensitive SIBO gut, which is the only place pu-erh is graded worse than an ordinary cup of tea.
