Everyone is talking about food containers, what about textiles - we breathe in and swallow quite a lot of dust every day, mostly coming from them. Even if you're wearing pure cotton the others may not and the office carpets and furniture are all plastic, getting torn every day.

    According to a report compiled by the EU, the largest group of primary sources consists of the small particles released from the washing waters of synthetic textiles, such as fleece clothing. Wear particles from tire and road materials are the second largest primary source. Together, these primary sources form 15–31% of the microplastics in the oceans, that is, less than one third.

    Secondary sources include larger plastic items, such as bottles, bags and fishing nets that are ground into microplastics over time. These are estimated to form 69–81% of the sources of microplastics in the oceans, that is, at least two thirds.
The fleece loving hippies are killing us faster than the car fanatics are, but only just.

Coke in "aluminum" is actually coke in plastic; the cans are lined.

I think they're talking about McDonalds which uses stainless steel tanks for delivery. I'm pretty sure those aren't lined with plastic.

The cup linings and soda dispenser hoses and miles of water supply lines to the store your house and everywhere typically are.

If you can, there are some great borosilicate glass containers out there. I use them for everything. The ones I have seal well enough that I can fill it with soup and stick it in a backpack, ride somewhere and it's fine on the other side. Thick enough to be basically unbreakable, microwavable, dishwasher-safe, etc. Don't need to worry about tomato staining either like on plastic. I've been thrilled with mine.

> basically unbreakable The clip-retaining rims seem to love to chip on the IKEA 365 style ones. The long-tabbed GlassLock ones seem less vulnerable to that. Which not unique to glass boxes, I'm still amazed by how robust the living hinges can be, some are going on 10 years and haven't split yet.

Yeah we’ve got ~20 or so of the Ikea ones and we do love them, but a few have chipped in that way.

They’re still amazing for the price though considering how thick they are and how heat/cold/etc resistant they are. Many other brands crack if dropped even a small distance, or shatter if pouring hot food directly in from the stove.

I love using these for things like casseroles. I can bake it directly in the container or even freeze a raw casserole and when ready, defrost and bake. One less dirty dish and no need to transfer and make sure it will fit.

Not a huge deal, but heads up from 3d ago that pyrex is now often tempered soda-lime glass & not borosilicate & is somewhat succeptible to thermal shock breakage. https://news.ycombinator.com/item?id=36206565 PYREX all caps should be borosilicate still & mostly immune (within reason).

I learned this one on a very unhappy thanksgiving! It shattered so explosively that every single single food dish was contaminated with glass shards (and some of my blood).

That ended up being a fast food for dinner night.

There are a lot of interventions to avoid plastic and chemical exposure that greatly decrease your exposure with little effort (avoiding drinking from plastic water bottles) though there are others which seem productive but have marginal impact. Is there a website anywhere that gives a list of easy changes you can make in your life to avoid plastic exposure and with alternatives? I feel that the impact of environmental pollution in the world and tactics to avoid it is a big mirage of anxiety half-baked solutions.

My mum when I was a kid in the 90s: we don't store things in plastic, glass or ceramic only Me when I was a kid in the 90s: mum is a f'ing idiot wtf is wrong with plastic this hippy shit is dumb My mum 2020s: so plastic huh? Me 2020s: ugh.

will be interesting to see if plastic ends up being our modern day equivalent to Rome and their lead pipes

There's a delicate balance between adhering to empirical data and paranoia of something.

On the one hand, you can point at mountains of data that show for the most part, to our knowledge, many plastics are safe when used appropriately. Specific cases have shown otherwise (e.g. BPA use and hazards in certain plastic manufacturering is a well studied example). Then there's all the cases where we have little evidence it's harmful. Our ignorance of harm doesn't mean there isn't harm though.

Transition to paranoia. Everything we don't empirically know is a non-hazard and non-dangerous and should be avoided or leveraged very cautiously. We use materials that have been around for ages like wood and ceramics because we know most the hazards at this point and rely on the maturity to mitigate risk of the unknowns.

Somewhere in between we can try to reason about things, but frankly we don't know either way, so either extreme argument (avoid at all costs, use it because it's safe as far as we know) is rational.

The Roman's has no reason to think lead was hazardous until it was a bit too late. Marie Curie had no idea she was slowly killing herself. In some places where time isn't critical, we should probably lean towards the paranoia and tread cautiously. In times where time is important and progress should be made we should tread more toward risk taking and accept the unknowns while trying to manage risk as we go. No matter what risk exists. Lead propelled the Roman's in some aspects, then in some perspectives may have been one of their ultimate downfalls.

The people who think seed oils are unhealthy and cause inflammation are up there with the most ignorant folks in nutrition.

So, trans fats which are a known contributor to heart disease are healthy now?

I love comments like these, it keeps reminding me how misinformed the dogmatic folks are in the nutrition community. I'll let you reconsider your question, and also link to you (one of) the double blind, randomized, controlled studies that shows replacing saturated fat with vegetable oil significantly reduced CVD outcomes https://www.ahajournals.org/doi/10.1161/01.CIR.40.1S2.II-1 .

weird. I never had a problem with pyrex. Must be something to do with the environment the glass in your specific case is exposed to.

Pyrex is just tempered glass now. You have to trawl yard sales and antique shops to find the borosylicate version.

There's actually two variants, confusingly differentiated via capitalization.

https://en.wikipedia.org/wiki/Pyrex

> The pyrex (all lowercase) trademark is now used for kitchenware sold in the United States, South America, and Asia. In Europe, Africa, and the Middle East, a variation of the PYREX (all uppercase) trademark is licensed by International Cookware for bakeware that has been made of numerous materials including borosilicate and soda-lime glass, stoneware, metal, plus vitroceramic cookware.
