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

So having abnormally high omega-6 to omega-3 ratios in your food when natural food hardly has any omega-6 fats doesn’t sound like a problem to you?

> natural food

Are seed oils something other than oil derived from seeds? As in, some of the most natural possible foods?

Metal? Lighter and less prone to breaking than glass. Also less inert maybe, but probably better than plastic.

No way to microwave sadly :/ Hard problem to solve. I wonder what the best effort-per-payoff is in this scenario. Perhaps cutting out plastic water bottles would be 90% of the benefit, and the plastic containers for food is 10% of the benefit but tremendously more effort -- I don't know (never did research on this).

Microwaving and heat is the 90%, I believe…

Coca-Cola cans, and probably many others, have plastic coating with BPA on the inside. But that doesn’t matter much in comparison, because PFAS (corrected) are in the product, allegedly: https://amp.theguardian.com/environment/2023/jan/19/simply-o...

It's not BPA anymore, but something very similar. Also, PFAS is not the plural of PFA - those are actually different classes of chemicals.

Did they switch recently? As of 2020, it seems there was BPA in aluminium can linings of Coca-Cola? https://www.coca-cola.co.uk/our-business/faqs/does-coca-cola...

Aren’t the lids typically plastic though?

Yes, but the vast majority of the container being glass still has advantages. For example, whenever heating it, you'd remove the lid and only be heating the glass.

Actually, on at least some of the range, Ikea advertise that the lid can be used as a splash guard in both microwave and conventional ovens (at least on my local Ikea website that's what it says), and has photos of the whole kaboodle in the oven: https://www.ikea.com/hu/hu/images/products/ikea-365-eteltaro...

Make it easier for her by taking on the chores of washing them and preparing them. If you're insisting she do something differently, ask her if there is anything you could do to make it easier for her to do it -- since this is clearly a more important change for you than for her (at this time).

I did offer to do that but the main problem is she doesn't want to carry the items and it can be heavy for her with all the tools she carries (she's a piano technician). Really only solution would be finding lightweight alternatives, but haven't had luck with that.

It may be worth looking into silicone containers.

They do these kinds of studies on mice because mice have a high homology with humans, and a huge number of the findings extrapolate to humans.

Yes, and as a model organism they're fantastic. But I feel any and all studies on mice need to have "on mice" always in any published study or news report about that study. But it's one thing to pump a 100g/100g of micro plastics to bodyweight directly into the brain of a mouse and another to study mice in a mostly natural environment filled with plastic dust in similar proportions to what we find in our human lives.…

Exactly, thank you.

I mean, I can understand doing those kinda of experiments in animals since it would be unethical to do them in humans (not going to discuss the implications of doing tests in animals either, let's just say that doing them in animals is less controversial). But as always the title omits this crucial point of information, mostly probably because this generate more clicks for the website, but I hate this trend so much.

You can find ones with glass lids. Here in the UK we're lucky that Pyrex is still borosilicate glass, and there are some I've seen with glass lids that are advertised as "zero plastic".

PYREX all caps should be borosilicate. Indeed harder to get now. Submission from 3d ago on the this: https://news.ycombinator.com/item?id=36206565

Snopes found a mixture of true and false in these rumors about Pyrex: https://www.snopes.com/fact-check/exploding-pyrex/

My impression is that finishes free of petroleum products have become somewhat of a niche cottage industry these days. So I wouldn't assume anything acquired finished by someone else is free of such things, regardless of whatever once-precise names they used to describe the finish. Even when you try DIY-finish something with an eye towards food-safety it's rather challenging. E.g. the "Boiled Linseed Oil" you find on…

Why would oil companies dispose of their toxic byproducts when they can sell them to companies who will poison the public with them? Since it makes them money and there's zero risk of legal repercussions for it, the only thing that would stop them is having morals and the oil industry certainly isn't burdened with those.

This transitive logic applies to chemical companies and pharmaceuticals, more than anyone realizes.

It would be worth checking that the concentrations of microplastics used in this study are of a similar concentration to those found naturally. Otherwise the research is not very meaningful.

It's still worthwhile to look at 10x and 100x concentrations since these things bioaccumulate. Whatever negative effects are happening at 1x should be studied as we crank that concentration up. Might be fine now, but in 100 years? We should probably have an idea how the harm/effects scale

This is a good point. I hadn't thought about bioaccumulation. Thanks for raising.

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 .

I love pompous comments like these. I'm not part of a "nutrition community" and I'm actually pretty open minded to these things. Hence why I asked. But you seem to be unable to have a civil conversation without being an asshole. Congrats.

Let's throw around studies like pokemon cards then. I have a study too: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3955571/
