From the actual paper: "With this in mind, an in vivo study was designed to determine the effects of these MPs [microplastics] in a rodent model (Figure 2A). Following a 3-week exposure to PS-MPs, C57BL/6J mice were tested in a series of behavioral assays including the open-field and light–dark preference tests. Both assays showed significant changes in parameters such as distance traveled, rearing activity, and dura…

Good thing you’re not a mouse.

My suggestion, which isn't rocket science: Ban plastic food containers for any type of long-term storage or anything that gets heated up (and different plastics have different microplastic shedding profiles, so ban the worst first) and also ban PFAS in anything that gets close to food. It will increase costs, but the alternative is we poison ourselves, so it is sort of needed. Phase it in so that industries have time…

It's almost as if it was the adoption of the microwave oven that signaled the roller coaster was beginning to race downhill. God, I wish I could go back to non-plastic packaging. Natural peanut butter I can still find in glass, as I can for my jelly. But mayonnaise, ketchup and countless other items are in plastic-only containers.

Things like the microwave lowered the friction point for making food and snacks so I'm sure it is part of it. I honestly think people forget how much more friction was involved to have a bite to eat even just 20 years ago, and even more so 40 years ago.

Plastic food packaging is crazy to me, but also lowers the cost of food because of transportation. I would love to see a situation where you buy food in glass bottles and take thise cleaned glass bottles back to the store for resuse, for example. On plastic, on strategy for healthy eating is to be as strict as you can about buying food packaged in plastic. This is getting harder, but it forces you to get the majority of your food from the produce and butcher. Of course, one lived in places (like DC) where such a strategy might seem less possible.

Perhaps related to microplastics interfering with the endocrine system. https://www.niehs.nih.gov/research/programs/geh/geh_newslett...

Which is ironic as to the fact that fatty products are normally encased in toxic plastics.

Alongside fruits and vegetables

I'm still shocked that there hasn't been more of a regulatory push to eliminate single-use plastics. In the US the closest we've gotten is banning plastic straws and charging for plastic carry bags. Everything I've read about plastic recycling points to it being ineffective and requiring massive amounts of fossil fuel to move the waste around the globe, often with much of it just getting burned or dumped into the env…

I agree there’s far too much single use plastic. For example, it baffles me why non perishable products are still sold in transparent plastic bags. If they go to the store they generally get taken out of the plastic bag and put on display. If they’re sold online I have to waste time opening and discarding of a random plastic bag. Why? What purpose does it serve? If you’re that desperate to wrap it in something why no…

> Why is the cable in the box also in a small plastic bag?

The charger I bought this weekend was in a cardboard box. Inside that cardboard box was a plastic shimmy bracket, keeping things in place. The charger had a plastic film adhered to it, but not the whole thing, just like the on the sides kind of. The cable was tied together with a velcro band (plastic from the futor!). On the plugs of the cable were little plastic protector caps. The box itself was wrapped in plastic of course. There was a booklet, not plastic.

The material world we've surrounded ourselves with really is made of plastic, disposable trash.

This is the third time this week I've seen a study related to microplastics. Should I be alarmed? If so, what can I even do? If I'm understanding these studies correctly, these microplastics are everywhere. In our bodies, in our water supplies, in our food. And we can't even get rid of them.

You can't do anything about it. Personally, I think it's probably being a bit overblown. It's definitely not good but some of these articles make it sound like you'll drop dead in a few days.

Plastics have enabled us to keep food fresh and have done a lot of things to keep humans living longer and healthier than they ever could in the past. Our modern food preservation couldn't exist without them.

So, yeah we need to be better but I think people should be looking at the overall picture. I don't see an alternative for plastic right now.

There are two macro population health trends that suggest we are somehow poisoning ourselves at a large scale. Most people do not relate the two, but I personally wouldn't be surprised if they have related causes. The first is the Flynn effect, which was rising IQ levels decade over decade, which halted and then reserved for most Western nations around 1990s/2000s and is now declining: https://en.wikipedia.org/wiki/F…

Also the metabolic syndrome/obesity epidemic. 40% of US adults have obesity. By 2030 about half of US adults will, and in 29 states more than half of adults will be obese. We see obesity becoming increasingly normalized. People feel powerless to stop it and that we should just accept it. It feels to me like there is something besides diet changes happening to us. That's part of it, but I wonder if microplastics or so…

Big thing you would expect if it’s due to general plastic/pollution prevalence is obesity in pets/wild animals.

> But mayonnaise, ketchup and countless other items are in plastic-only containers. One idea is to stop consuming these, given they are not food and are not nutritious in the first place. Your body (and mind) will thank you.

This is probably mostly the right answer to the obesity problem. Most condiments and packaged "food" is garbage food. If argue that a majority of products in a typical grocery store don't need to be there.

The Flynn effect reversal has a pretty simple (but unpopular) explanation that has nothing to do with microplastics.

Could you please share this simple explanation for those of us who aren’t as smart as you?

I assume dysgenics (which you’d assume is happening if family size is inversely correlated with education and or income).

AFAIK there are some studies that show that dysgenics are at least not the only effect in play (e.g. this study https://www.pnas.org/doi/full/10.1073/pnas.1718793115). But I am far from an expert on the topic.

Obesity itself is oestrogenic. It's the calories, stupid!

I used to think this, that the obesity thing was just a function of an increase in calorie consumption and a drop off in physical activity. I just can't take this view seriously anymore. When you look around today, there are body types that never existed prior to the 1970s - at least at any kind of scale. Comparing pictures of family gatherings from the 1950s through the 1970s, and then to the 1990s and beyond and there's such a stark, shocking difference. Two of my cousins had gastric bypass surgery (before they passed away), and there was never a real change in their diet or exercise (one was a cop, so it's not like he didn't get exercise). Something is poisoning us in America, and if there was one issue presidential candidates should be talking about that should be an easy bipartisan win it's health and fitness.

Plastic food containers aren't even close to being the largest source of microplastics. Synthetic fibres in clothing (like that cotton-poly blend shirt you're most likely wearing) and motor vehicle tyres are some of the bigger sources. These both also release particles directly into the atmosphere allowing them to get absolutely everywhere, unlike plastic in landfills that probably has a harder time escaping into the…

I think bhouston is talking more about poisoniing one’s own body with microplastics, whereas you’re talking about polluting the environment.
