>Our data shows a statistically significant correlation between PFAS in the blood and harmful blood lipids linked to cardiovascular risk.

Fast food consumption is also associated with both. Was this controlled for? How about BMI?

[thomasmg]

The paper is available, so feel free to check yourself. BMI was taken into account. Fast food I do not see, but where did you read about this association?

At the end of February this year the FDA banned PFAS in food packaging which was prevalent especially in paper products which held greasy food. If you ate a bunch of French fries there was a good chance you were exposed to a significant amount of extra PFAS. This study could be finding a correlation between diet and PFAS exposure and nothing more. I’m not saying it is but if not corrected for the signal is suspect.

I do not have a link, but have read it in multiple journals.

The MAO is entirely plausible. Many fast food wrappers are lined with PFAS because of its temperature stability and hydrophobic properties. At high temperatures these coatings also leech the coating.

"Fast food consumption is also associated with both"

I'm not arguing the point here but why would fast food have more PFAS in it? Seems these days all food is grown under conditions and goes through similar handling before it gets to customers.

Many fast food wrappers/containers contained PFAS until very recently [0]. Putting hot food out of a fryer into those containers would leech some of the PFAS into the food.

Paper straws and paper wrapping, cartons and so on are lined with PFAS. Paper isn't waterproof so to get the green credentials they coat it with PFAS.

That cheeseburger wrapper, feels waxy doesn't it? That's PFAS.

It seems food packaging is at fault here [1], and fast food has much more individually wrapped items, small ketchup bags, and even before preparation often is single-portioned. Meaning insane amounts of touching packaging material compared to real food.

The switch from plastic to "biodegradable" materials for food packaging will probably be shown to be a grave mistake in the future. Natural cardboard will quickly loose it's strength if exposed to hot oily food, so they are usually coated with materials to prevent that.

I also suspect PFAS or similar coatings are used on paper cups to aid separation when stacked.

A few years ago I visited a Burger King in Spain and the cups have a strange slimy feel, which felt similar to when you get PTFE spray on your hands (good as a lubricant where you don't want it to spread to nearby parts like oil).

[hokkos]

in the study the confounding factors adjusted for are "certain risk behaviors (alcohol consumption, smoking), obesity and lipid-lowering medication" and they "generally decreased the strength of and number of significant associations, but did not substantially change the overall patterns".

Fast food is also full of PFAS.
