A recent report from a woman who found she had high pfas in her blood:
https://www.bbc.co.uk/news/articles/ce8z8pv1e0ko?utm_source=firefox-newtab-en-gb and some strategies to reduce the risk:
Increased fibre intake in the diet (although they don't explain why this helps)
Menstruation (not really an option for those of a male persuasion, children or older women)
Having a child (you pass on the pfas to them

)
Replace non-stick cookware with ceramic, stainless steel or cast iron alternatives,
Use a water filter
Switch to PFA free cleaning products.
Look for "fluoro" or "PTFE" and avoid those ingredients in make-up and hair products
Keep carpets vacuumed if these are likely to be treated with stain repellents,
Avoid "waterproof" or "stain-repellent" labels unless they have a PFAS-free certification
Eat only organic foods as pesticides often contain pfas to stop them washing off in rain
