You only have to huff it for a few seconds, and then turn off the heat. The symptoms are what shows up hours later.

how much of "it" is there? what is the concentration? dose makes the poison, not time.

These so-called perfluorochemicals are toxic to humans at single-digit parts per trillion.

If you live in the US, chances are your blood already contains these chemicals at 4,000 ppt or greater (four thousand parts per trillion is the nationwide average).

For some things maybe, but usually there's an option where the risk is pretty negligible. I feel pretty confident we're not going to declare wooden spatulas to be a massive health concern.

There's a risk for wooden ones that are glued, specifically bamboo, or finished with something toxic. You should probably stick to ones made from a single piece of hardwood and are unfinished. There's also a risk that any cracks will fill with bacteria.

The latest issue of Fine Woodworking agrees and explains why this is true:

* "The Best Food-Safe Finish May Be None at All", https://www.finewoodworking.com/2024/10/10/the-best-food-saf...

TLDR; unfinished wood that is rinsed and dried on all sides will naturally trap and kill bacteria as it dries. Any finish interferes with this process.

> The magic of deposit refund system is that you only pay more once. Your insight into the economics of this is shallow. If plastic is cheaper than glass, a "deposit refund scheme" doesn't fix the fact that forcing everything to glass makes it more expensive. Glass jars aren't just washed and reused, they have to be melted down to be reused at all. There's a big fuel usage penalty there (not to mention this is fossil…

Glass jars tend to have small fractures, especially around where the lid/cap are, making them unfit for reuse. Inspection is tedious and manpower-intensive. Melted down and put back into the blow molds, if reused at all. Industry works differently than the political perception of it. You might want them to be reused, but it's just not the way the world works.

Instead of jacking off over political videos, go watch some of the non-political ones of the "how it's made" variety once in awhile.

No, they aren't. At least, not in the way you're interpreting the word "toxic".

The fact that you're telling me that I'm currently thriving with 1000x the "toxic" dose you just quoted should tell you that at least one of the statements is exaggerated.

Again, there are people out there who will tell you that any exposure to certain chemicals is "toxic". These people are not worth listening to.

You are doing damage control for multinational chemical corporations. Why would you be worth listening to?

Is she wrong?

Well she's been saying this for at least 10 years now I think, so she's lived longer than she expected to.

She also has guests and visitors, so even if she doesn't care about ingesting microplastics herself, she should worry more about them I should think.

I live in Germany and I see glass bottles that have been obviously re-used--e.g., beer from one brewery in glass embossed with the slightly-raised lettering of another brewery.

I couldn't tell you whether it's economically efficient or energy-efficient to do things that way, when you consider all the direct and indirect inputs; any more than I could tell you how to make a pencil. But I can tell you that Germany does it.

Usually “nonstick” in the cooking context means “nonstick without any added fat”. So a stainless steel pan is never “nonstick”.

Fear of fat has completely killed this country's health. Fat is a necessary part of food. Fat doesn't make you fat, refined sugar does.

while factual (and quite alarming if I'm honest), it is factually a non sequitur for the commonly held definition of "non-stick pan"

people generally don't use metal tools on enameled cast iron, which is plenty strong

you can use wood on enamelled cast iron. Why would you use a spatula with enamelled cast iron?

to flip an egg?
