Half the story

The Reel says

Air fryers do not cause kidney cancer or harmful PFAS chemical build-up?

checkthis · automated fact-check · How we check · Reel by @chefwinterr

While air fryers use PTFE non-stick coatings, PTFE is inert, non-toxic, and not absorbed by the body, and air fryers operate below its breakdown temperature. Air fryers commonly use PTFE non-stick coatings, which belong to the PFAS family, but health authorities emphasize that PTFE is non-toxic and cannot be absorbed or metabolized by the human body. Air fryers operate at temperatures up to 450°F, well below the 500°F threshold where PTFE breaks down into fumes. Poison Control confirms that air-frying equipment is not known to cause cancer.

The trick: Exaggerates

It inflates the facts beyond what the evidence shows (known as exaggeration).

“with years of daily use, studies have linked that PFA's build-up to a higher risk of kidney cancer”

The video conflates inert, non-absorbable PTFE used in cookware with toxic, bioaccumulative PFAS compounds to falsely claim daily air fryer use causes kidney cancer.

What the Reel doesn't tell you

How it plays you

It wants you to think: “So you should stop using air fryers and use a food scanning app instead.”

Normal air fryer use operates below PTFE degradation temperatures, and inert PTFE is not absorbed by the body, so air fryers do not cause PFAS toxicity or kidney cancer.
