PFAS (and, to a lesser extent, plasticizers) circulate from the blood to the gut ~5 times per day through enterohepatic circulation (https://en.wikipedia.org/wiki/Enterohepatic_circulation). This is why cholestyramine was shown to be effective at reducing serum PFAS by up to 60% in a Swedish trial.
Blood donations are also somewhat effective, saunas less so. Also, to be clear, PFAS are very different from microplastics. PFAS are the Teflon chemical.
> the Teflon chemical
Teflon is PTFE, which is fully fluorinated but is also very much a plastic: it’s a highly unreactive solid at reasonable temperatures (which sadly do not include temperatures commonly encountered on stoves).
By “the Teflon chemical” are you perhaps referring to the various nasty liquid, water-soluble surfactants commonly used in factories that make or process PTFE? Those include PFOA, PFOS, and the newer and not obviously any safer “GenX” compounds.
Yes, they are referring to PFOA/PFOS; they're talking about PFAS which is the broad class of chemical compounds that includes PFOA/PFAS. And PFAS are not plastics.

I wonder if there's a safe way to equip people to just do simple bloodletting if they have high exposure to PFAS. I mean obviously it's better to donate, even in that case, given the steady state of most blood banks. But it's still a bit of a pain in the ass.
