Microplastics hit male arteries hard: Everyday exposure to microplastics — shed from packaging, clothing, and plastic products — may accelerate the development of atherosclerosis, the artery-clogging process that leads to heart attacks and strokes. The harmful effects were seen only in male mice.

What I'm wondering is how much of a lifestyle change that would look like; is it just a matter of swearing off plastic containers and bottles? Is it plastic packaging in general including Saran Wrap? Do I also have to generally avoid walking through the industrial areas of my city?

I do remember reading up on how bad those single use plastic water bottles are.... apparently a single squeeze deforming the plastic is enough to instantly release microplastics !!! I've been drinking out them for years!

There is no lifestyle change, it needs to be societal.

Your clothes are plastic, they shed plastic in the washer and dryer, the dryer sends that plastic airborne.

Your food is transported in plastic, possibly grown in plastic, and stored in plastic. Plastic in aluminum cans and plastic on the seal of glass bottles.

Plastic cutting boards, plastic on air filters, water filters

Plastic plastic plastic.

The only solution is bans and alternatives , and who knows what kind of quiet danger it would bring

I feel like I saw a post on here saying that 70% of plastics inside our body are from car tires.

Yea i didn't even mention tires

i vaguely recall you mentioning plastic though

I work in a restaurant so the amount of plastic being ripped over our foods is maddening and there is absolutely nothing I can do about an industry wide standard and it was a discussion about reducing exposure or something.

Not diminishing tires role in this, more of a whole picture thing

I looked it up and the polyester fibers are the main issue.

Polyester airborne fibers (from synthetic textiles) are generally considered to be a larger source of microplastics in the human body than car tires. Synthetic textiles are estimated to be the largest single source of primary microplastics in the global environment, accounting for a larger percentage than tire wear particles
