I'd love to have one of these, but I can't do it at that price. I'll just keep getting microplastics in me, I suppose..
Mocha pot
Did someone test the aeropress and find lots of microplastics?
A few people mentioned it here.
If its a concern, aren't (e.g.) tupperware and coffee flasks too?
Yes, all plastic food service items are of concern.
*Though the studies on harder plastics have been focused on plasticizers leeching into the food or liquid.
Micro plastics are a concern with all plastic food containers, especially when you’re heating something in them.
It’s long been a recommendation to not reheat leftovers in plastic
If you instead use glass or stainless, you don’t have to worry about it. Or in theory they last longer
I think the idea is that adding boiling water to something made of plastic probably leaches chemicals.
As far as Tupperware and coffee flasks go, yes. This is also a concern.
There's plenty more research to do about microplastics. I'm sure the plastic aeropress is still significantly better than using soft plastic disposable coffee pods. I'm not a scientist or doctor though so don't take my word for it.
of course not. People read it on Reddit.
There are no 'microplastics' in aero press.
Oh, everyone is now scared of micro plastics that have been around for 70 years and no lab has yet to find a mechanism for toxicity. Meanwhile, we have been implanting plastic prosthetics, shunts, pacers, etc. for 70 years and there were no issues.
Americans love to be scared. BPA doesn't give you tits either.
"We've been using lead in everything for ages, and everyone is fine!" -- You
Science takes time, that's how consensus works, but there have been eye-opening studies if you have been paying attention.
Everything about micro plastics is about how they are everywhere. With them everywhere you'd expect to see them causing a lot of harm but they're not. It really looks like the risk is much lower than it is presented
You picked the wrong guy for this. Junk science in a second rate journal is not eye opening. Correlation is not causation.
"Compared to adjacent non-cancerous tissues, tumor tissues exhibited a greater variety and distribution of microplastics. "
Because cancerous tissue does not have the intact structure of normal tissues. They see all kinds of stuff in tumors that the lymphatic system clears out of healthy tissues. That paper does not show HOW plastic polymers could cause tumors, because no one can show this in 50 years of research.
Again, we have been implanting plastic stents and meshes and prosthetics for 60+ years. The experiment has been done.
Since this thread is looking for something to be afraid of, look at coffee brewing with and without paper filtration. Filtered brews yield caffeine and compounds healthy for liver functions. Unfiltered coffees contain diterpenes, cafestol and kahweol, which signficantly raise total and LDL cholesterol, which is bad. Actual science, not media driven hype fear.
Let’s assume you’re right (you’re not, but for the sake of argument)
There are no problems with microplastics. However they are near ubiquitous throughout the environment, across our food chains, in every part of our body. We’re long past the point of being able to clean them up And there are more and more every year.
Are you really so comfortable that they will never cause problems for ourselves, or any of the millions of types of life forms in our biosphere? That there’s no threshold that’s dangerous? Ever?
We’re being foolish and short-sighted with our impact on the environment, turning what may not be a problem into if it is, we will have created a worldwide disaster that we can’t do anything about
