Short term: grow your own food.
long term: politics

you don't. you can try to mitigate it by using less plastic yourself, buying local foods, whatever, but it won't make much of an impact.

the less bad news is that plastic, by its own properties, is chemically relatively inert, so they're really not that harmful. they're still bad, mind you, just not all that hyped up to be.

That's the neat part, you can't

They’re in he air, the water, the food, your brain, apparently. Your reproductive fluids…there’s literally no escape. We signed this pact with satan when capitalism determined that profit is the only thing that matters.

The first step we could take? Bringing the exploitative and murderous system of capitalism to its knees. So we can promptly shoot it in the back of the head. Then, maaaybe our children’s children’s children would have an option to avoid microplastics.

My take-aways from this article:
There's no good study on microplastics in humans.
They've tested "pristine" plastic on mice and it's pretty bad.
The plastics we're exposed to are loaded with chemicals and toxins.

She carries a stainless-steel water bottle and avoids plastic water bottles. She doesn’t microwave food in plastic containers and only uses glass, wood, or metal kitchen items, including mixing bowls, spoons, cutting boards, and food storage containers.

takes her shoes off to avoid tracking in dust from the outside and uses a HEPA filter to capture particles from the air.

Great point. Tires are one of the leading products polluting our environment and lungs.

This article also links to The Program on Reproductive Health and the Environment at UCSF which offers a guide for minimizing exposure to bad stuff. https://prhe.ucsf.edu/toxic-matters

Here's a relevant NYT Article - How to Minimize Your Exposure to Microplastics

You can't completely avoid them, but avoiding plastic food/drink containers is an easy thing to do. Good for the environment too, not just your health.

Clothing and textiles from natural fibres. No rubber tires as they are major shedders of micro plastics.

Short answer: very simple

Avoid plastic

You buy bottled water?

That has Microplastics.

You buy or store food in plastic?

Microplastics..

Use plastic straws?

Welp, Microplastics

Etc...

Basically it's difficult to avoid it since we use plastic almost everywhere daily, but not impossible.

I read an article not that long ago that stated that they're in men's testicles and women's ovaries. In other words, they have become a part of your physical body and will become a part of the bodies of the next generation (likely several generations). They're unavoidable.

That's the fun part. You don't.

"Plastic came out of the Earth; the Earth probably sees plastic as just another one of its children. Could be the only reason the Earth allowed us to be spawned from it in the first place: it wanted plastic for itself, didn’t know how to make it, needed us. Could be the answer to our age-old philosophical question: “Why are we here?” Plastic, assholes!"

George Carlin.

Afaik it tends to concentrate further up the foodchain, so keeping meat, especially fish, out of your diet will help. Particularly filter feeders like shrimp and anything that eats those.

I'd also like to add that wrapping food in plastic reduces waste considerably, so you might want to look into that and balance your view against that.

Become a communist and start advocating for workers to run the economy because we wouldn't fuck ourselves over like capitalists will.

Just embrace them

Use only textiles made of cotton, wool or linen (I recommend linen in summer and wool in winter, since cotton isn't very good at conserving your body heat), look for a bamboo toothbrush, avoid foods in plastic packaging (this can sadly be difficult) and only put them in ceramic, metal or glass containers.

I assume your goal is to minimise the amount of microplastics inside your body, so the materials that touch your food are a priority. The amount of microplastics in your food or drink also depends on how long they are in contact with plastic. For example, if you have juice in a plastic bottle, drinking it right away or putting it in a plasticless container would probably result in less microplastics than storing it in the said bottle.

If you are more concerned about nature, try shopping at second-hand stores.

Read a material science book. Then think about exposure anytime you see plastic.
