This is expensive and time consuming Because this is not a permanent solution (the patient will get reinundated with microplastics shortly after the procedure), they will need reapplications throughout their whole lives. Thus, this will likely only be available to the ultrarich.
The article does point out that prevention is still the best solution. But the corpos make that hard.
- There are other ways to lower the amount of plastic in you. If you donate your blood you can measurably lower your pfas levels. Really just removing blood which carries plastic through your whole body will also lower your concentration of plastics. Because plastic is in the water, make sure you drink filtered water. They do make filters that will catch micro plastics and some will advertise it. If you want to keep your levels lower avoid hydrophobic coatings that sit next to food for extended periods of time and definitely don't heat that food next to a hydrophobic coating. Think microwaving food in a container with coatings that'll leach into the food. So bags of popcorn should be avoided like the plague, unfortunately.

  A while ago there was a reddit post about how you don't need bagged popcorn to pop popcorn. You don't even need any of them there fancy air poppers. All you need is a glass container and the popcorn itself. And it's true!
  The only part that presented any trouble was finding a safe container with a safe lid - during the process of popping, an individual kernel is super warm, so if it hits a lid that can't tolerate that it can melt pits into the lid.
  Other than that (and making sure you don't add too much popcorn, that stuff expands like crazy), just dump the kernels into your container, cover it up (don't forget to vent as appropriate) and then microwave as you would the bagged stuff. Add your seasonings, shake up the container, and enjoy.
  
  There's an even more accessible way to pop popcorn. Add oil to a pot, heat it on the stove and dump in some kernels. Optionally cover with a lid.
  
  That indeed is a functional method, but I'm not sure I'd call it more accessible. Unless you mean that more people probably own a pot than an appropriate microwave safe container, in which case, fair enough.
  
  That's how I did it for years . Turn the heat down when it starts popping and take it off the heat when it slows down.
  
  It's even better because you can pop in whatever fat you want. If you toss the salt in there while popping then it'll evenly distribute across your popcorn as well.
  
  Or use Flavacol instead of salt if you want movie theatre popcorn.
  
  This is the way
  
  So bags of popcorn should be avoided like the plague, unfortunately.
  Unfortunately? Popcorn is the least flavorful thing in existence. Just find some other bland edible material and put your toppings on that instead.
  
  Popcorn is just a method of eating butter or other oil-based flavours.
  
  If it's Veritasium, I would just recommend watching. End of sentence. This bloke is amazing.
  What's a "hydrophobic coating" in relation to foods?
  I don't use plastic to heat anything up. I may buy microwavable foods, but then scrape them into a metallic or class container and heat them in the oven (that's more out of necessity, as I don't have a microwave oven). And I don't like popped corn (though I kind of wish I did).
  
  I just hate that he exudes privilege. It's not his fault, he does amazing science communication. But man it's hard for me to watch his stuff.
  
  And if there's ever a brand integration, he'll spout their marketing drivel uncritically and try to pass it off as science. I can't trust him anymore.
  
  Yeah, that's a good way of putting it. I don't like him either, but the information is useful and/or interesting so I've been watching some of them.
  
  Hydrophobic coating loosely means a thin water proof coating on a material that otherwise isn’t waterproof.
  Example: the previously mentioned popcorn bags are paper based but with a thin plastic based coating. (Historically we used to use wax for this kind of thing but in the modern day it’s almost always plastic)
  Not that containers made of glass, ceramic, or metals that don’t corrode don’t need and typically don’t have hydrophobic coatings.
  
  Ah ok. Yeah, that makes sense. Thanks, mate!
  
  You can also pop your popcorn in plain undyed paper bags. Toss them in oil, put em in the bag, microwave.
  
  There are other ways to lower the amount of plastic in you. If you donate your blood you can measurably lower your pfas levels. Really just removing blood which carries plastic through your whole body will also lower your concentration of plastics.
  I'm pretty sure regular blood letting is actually not great for you either.
  
  Oh, and I suppose you've figured out a more modern way to balance the humors‽
  
  Describing donating a pint of blood every several weeks as “regular bloodletting” is really something. I mean I guess in a literal sense that is what is happening, but they literally will not take your blood if it is not safe to do so, including donating too recently.
  Edit: by the way, after thinking about this for only a few moments longer, i have realized you can probably do even better just by donating plasma only, and now you are not even losing your blood cells.
  
  I know pfas levels are immediately lower after the donation. I'm not under the impression that pfas levels stay low for very long i.e. long enough to safely donate blood again.
  Plasma donations can be done more frequently, though, so that might be actually effective way to reduce contamination.
  But, it's kind of messed up that we're donating contaminated blood and/or plasma. Is that good for the people that use our blood? Who knows!
  
  I think it’s definitely worth doing some serious math first before publicly writing it off. Even if its a marginal benefit, as long as its just a tiny bit greater than the marginal benefit you get from intentionally avoiding exposures as much as reasonably possible, then over time the PFAS levels will come down slowly but steadily
  Secondly, no its not okay to give people contaminated blood. But the blood is contaminated with something basically everyone is contaminated with already, and the person who needs transfusion will likely die without it, so it is kind of moot.
  But after only a few more moments of thought, if we were really concerned about it, we could just perform the dialysis on all the donated blood and plasma after it has been taken where we have economies of scale and nobody needs to be hooked up to a machine for it
  
  Looks like patients that receive hemodialysis treatment have lower pfas levels, so that actually might be viable!
- It is not expensive, assuming you don't mind giving someone else your microplastics. In fact, you can get paid about $100 to do it in most places. How? Apharesis is exactly what is performed when donating plasma.
  
  Once the plasma is collected, I wonder if you can perform dialysis on it at an enormous scale to protect future recipients while still keeping things economical.
  
  That would definitely be the way to do it, and with plasma you could mix individual donations into large batches for processing without worried about blood type
- The article already says everything you said. It’s not a “solution” to anything. It’s a small step to show that this is even possible. Perhaps it will help some people whose condition makes them extraordinarily sensitive.
  I swear people will find a way to shit on virtually anything and turn absolutely everything into class war.
  
  How many lemmings do you know that actually read the full articles? If an article interests me enough to read it, I usually try to summarize it in the comments, and, yes, point out its flaws.
  
  Your comment reads more like a rebuttal than a summary. If you intend to summarize the article for lazy lemmings, that’s cool, but present it as such.
  
  Ok. Good feedback. What can I do different?
  
  You could begin with “summary:”
