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.”
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???”
