alt Hacker NewsYes, there are a few things you can do. In rough priority / proven benefit order:
1. Eliminate as many items as possible from your diet that make use of PFAS based components, such as plastic linings. This means don't buy groceries packaged in lined packaging, this means don't cook with Teflon pans, and it means don't drink water from plastic bottles or bottles lines with plastic.
2. Get a whole-home water filtration system that is certified (NSF 53 or similar standard) to reduce/remove PFAS and if possible, on top of this do under-sink RO for drinking/cooking which is certified (NSF 58 or similar) to remove PFAS and use glass or stainless steel reusable water bottles to take water outside your home.
3. Exercise regularly so that you sweat and drink lots of appropriately filtered water, donate blood and/or plasma regularly.
4. Eliminate clothing or other items in your wardrobe that are coated with DWR or similar coatings. Don't make use of any PFAS-derived treatments/plastics in your clothing. This is especially important during the process of washing your clothes, as this generates microplastics which are PFAS contaminated and you can ingest them via breathing.
Everything else is basically guesswork, these are the only things known to have any benefit. We mostly ingest PFAS due to contamination in the food and water supply. This contamination is unavoidable, but we can greatly reduce exposure by making smarter choices about packaging materials and cooking methods, and a big one is simply not drinking anything that you can't confirm has been properly filtered and packaged.
I'm a bit extreme, I even brew and bottle my own beer and other beverages like soda and water kefir/kombucha to avoid exposure to externally packaged products that may be contaminated with PFAS.
You missed a few:
1. Don't eat out where they might have used PFAS coated nonstick cookware such as Teflon. It is not sufficient to avoid it at home.
2. Don't use conventional dental floss as it's made of PFAS. Find ones that aren't.
3. Intake substantial supplemental fiber daily, e.g. psyllium, as it binds to bile which binds and excretes a subset of PFAS.
4. Strongly prefer certified Organic foods as these don't use PFAS pesticides and PFAS containing sewage sludge, both of which are allowed in conventional foods.
Note that RO water requires monitor pH adjustment, plus adding sodium bicarbonate on top for meeting bicarbonate/buffer requirement, and a substantial increase to one's supplemental calcium and magnesium intake if not already high. RO water is not appropriate for non-technical persons. Countertop RO works pretty well, and it doesn't necessarily have to be under-the-sink. For everyone else, a gravity filter is better than nothing.

What's up with the haughty arrogance? It is both unjustified and wrong.
