US study that researchers say highlights chemicals’ ubiquity also shows PFAS association with seafood and red meat
New research aimed at identifying foods that contain higher levels of PFAS found people who eat more white rice, coffee, eggs and seafood typically showed more of the toxic chemicals in their plasma and breast milk.
The study checked samples from 3,000 pregnant mothers, and is among the first research to suggest coffee and white rice may be contaminated at higher rates than other foods. It also identified an association between red meat consumption and levels of PFOS, one of the most common and dangerous PFAS compounds.
“The results definitely point toward the need for environmental stewardship, and keeping PFAS out of the environment and food chain,” said Megan Romano, a Dartmouth researcher and lead author. “Now we’re in a situation where they’re everywhere and are going to stick around even if we do aggressive remediation.”

They go hand in hand with a lot of plastic packaging. Either way, it'd be nice to go after companies like DuPont, Bayer, 3M, and Honeywell as well as the oil companies that provide them the raw materials anyway.
Assuming that research is accurate, and also given that those 3 things make up a huge portion of my diet, then I'm probably mostly made of PFAS these days.
Same, except I eat brown and red rice instead of white. I also stopped buying pre-peeled shrimp because I read it has the highest level of microplastics among seafood.
Next up. Do you drink water? Turns out its all poison now!
Soon:
How does that coincide with your post-war Commie conspiracy, huh? It's incredibly obvious, isn't it? A foreign substance is introduced into our precious bodily fluids without the knowledge of the individual. Certainly without any choice. That's the way your hard-core Commie works.
I mean, based on the amount of bottled water people drink im pretty sure that could be a concern for most people. I don't drink water bottled in plastic because I think it's wasteful and contributes to the massive amount of plastic pollution already going on, but even if we consider that the recycling process is 100% efficient, those thin, flimsy bottles are still getting heated by and exposed to sunlight. It would be naive to think they aren't leaching plastics into the water. Just buy a cheap metal bottle and refill from the tap. That's where all the major brands get their water from anyway.
Because of their ubiquitous usage and environmental persistence, humans are exposed to a variety of PFAS, primarily through ingestion of contaminated water and food, though PFAS have also been detected in air, indoor dust, and consumer products (Domingo and Nadal, 2017; Sunderland et al., 2019).
While certain communities can be highly exposed to PFAS due to proximity to an industrial site or occupational exposure, PFAS exposure is ubiquitous among human populations, with 98 % of the U.S. population having detectable concentrations of PFAS in their blood (Calafat et al., 2007; National Center for Environmental Health Agency for Toxic Substances and Disease Registry, 2023).
In coffee, researchers suspect that the beans, water used for brewing, or soil could be contaminated. Previous research has also found coffee filters to be treated with PFAS, and paper cups or other food packaging also commonly contain the chemicals.
I'd guess it could also be K Cups and non-dairy creamer, but who knows
Like, we know toxins concentrate in water creatures. That's why you'll see way more warnings about fish you harvest on any DNR page than you will deer.
Someone already mentioned this indirectly but I think this correlation is because all three items mentioned go on to be cooked in cookware coated in PTFE or mixed with spatulas and other utensils coated in PTFE.
PTFE is indispensable for high tech uses such as well almost all processes where high temperature near water boiling point is required. 100 to 200C for example. Now, because of its original use as a food process coating, PTFE is about to be banned in a stupid way.
I much rather have it banned from food use articles and allow it for use in niche technology. That would make the material more expensive and so less profitable to use in stupid uses where other materials are available.
I actually did manage to sub out coffee for tea, and can now go a day without caffeine for the first time since college. It's kind of an empowering feeling, that I would recommend.
I just made a batch of white rice, once cooked I freeze it on baking paper. Not long ago I looked into baking paper, it's loaded with some kind of plastic non-stick chemicals.
The literature on PTFEs illustrates that it is, at best, uncertain whether there are health harms relating to contact and ingestion. Most of the studies struggle with confounds, controls, and sample sizes because almost literally everyone has been exposed to PTFEs. Toxicity researchers would not definitively agree that it is "completely harmless".
The other commenter is right, also, that PFOA and GenX (the chemical, not the generation) are more evidently harmful and both involved in, and released from, the creation of PTFE.
Just throwing this out here in case someone is like "wait, IS Teflon fine???"
