## Summary

A 2025 study published in Nature Medicine found microplastics and nanoplastics accumulate in human brains at concentrations 7 to 30 times higher than in the liver or kidneys. The video discusses the implications of these findings, particularly the potential for neurological damage, and offers practical strategies to reduce exposure and support detoxification.

### Key Points

- **Microplastics Concentrate in the Brain** [00:02] — A study in Nature Medicine found microplastic concentrations in the brain are 7 to 30 times greater than in other tissues like the liver or kidneys.
- **Lipophilic Nature and Blood-Brain Barrier** [00:28] — Microplastics are lipophilic (fat-soluble), which may allow them to cross the blood-brain barrier and induce damage in the prefrontal cortex and amygdala.
- **Study Details** [00:43] — The paper, 'Bioaccumulation of Microplastics in Decedent Human Brains,' analyzed about 20 brains from deceased individuals, along with liver, pancreas, and kidney tissues.
- **Trend of Increasing Concentrations** [01:39] — The data suggests a trend of increasing microplastic particle concentrations in the brain and liver, with the majority being polyethylene nanoplastic shards or flakes.
- **Concern Over Filtration Organs** [02:07] — Microplastics are found in the brain rather than primarily in the liver and kidneys, which are the body's main filtration organs, raising concern.
- **Microplastics in Other Tissues** [02:23] — Research also shows microplastics concentrate in the carotid artery, placenta, and penile tissue, indicating widespread accumulation.
- **Dementia Cases Show Higher Presence** [04:17] — Brain samples from dementia cases exhibited even greater micro and nanoplastic particle presence, though the data is associative, not causal.
- **Mitigation Strategies** [04:46] — Recommendations include avoiding plastic food packaging, not drinking from plastic water bottles, using stainless steel mugs, and not microwaving food in plastic.
- **Real Evidence, Not Conspiracy** [05:28] — Microscopy images show numerous microplastic particles in prefrontal cortex tissue, corroborating findings in other tissues and emphasizing the reality of the issue.
- **Call for Larger Research Effort** [06:11] — Given the rising environmental presence of microplastics, the study compels a larger effort to understand their role in neurological disorders and other health effects.
- **Sauna and Exercise for Detoxification** [06:40] — The speaker suggests sauna use and daily exercise to activate the circulatory and lymphatic systems, potentially helping to eliminate microplastics through sweat and urine.
- **Other Strategies** [07:47] — Blood filtration techniques are mentioned as another potential tactic, though the speaker emphasizes the importance of supporting the liver, kidneys, and brain.

## Transcript

concentrated in your brain. In fact, the concentrations of microlastic in to talk about in this study that was published in nature medicine, was between 7 and 30 times greater compared
to other tissues in the body. Now, I think this is really important and this is not to scare you. This is just to let you know that you need to take this very seriously because it turns out that the brain because it's fat soluble. These
microplastics are lipopilic in nature and so forth. Maybe they have a brain and cross the bloodb brain barrier where they can induce damage within the prefrontal cortex and the amygdala and other parts of the brain as this
analysis found. As I mentioned this was published in 2025 in the journal nature medicine. The title of this paper is bioaccumulation of microplastics in descant human brains. So they analyzed roughly 20 some odd uh brains uh from
deceased individuals. They died from a a variety of different causes. But the tissues not just the brain, the liver, pancreas, uh kidney and also the brain.
But as you can see here from figure one part A and B the concentration of particularly polyropylene and polyethylene which again this is found in our food packaging. It's found in our water. It's found guess what in your
water. It's found guess what in your clothing your furniture. This stuff is more mindful of this. And I'll talk about strategies momentarily but let's dive into this in a little bit more depth. The investigators say the present
data suggests a trend of increasing microplastic particle concentrations in the brain and the liver. The majority of microplastic nanoparticles found in tissues consist of polyethylene and appear to be nanoplastic shards or
flakes. Micro nanoplastic concentrations in normal descent brain samples were between 7 and 30 times greater than the concentration seen in liver or kidneys. Now, why would we care about the liver or kidneys? Well, as you know, these are
your body's main filtration or uh organs. And so, if they're ending up in the brain, not the organs that are responsible for filtering them, that's of concern. Now, it's important to recognize that we also see microplastic
particles concentrate within the corateed artery. Uh there's research showing that it concentrates within the placenta as well as the penile tissue dysfunction. So, we've addressed those studies before and this is one of the
first reports of its kind to find that microplastic particles are now found in the brain which is which is totally frightening. So, before we go on, I just want to thank our show sponsor for this episode, nadsunder.com, the makers of
certified organic cotton underwear. Now, for men, this is really important because, as I mentioned, we know that we have these microplastic particles in all sorts of commercial clothing. And why do we care about our underwear? Because
in the sauna, you're sweating, you're moving your body, you're moving your pelvis, and your legs are rubbing against your boxers, you could be releasing microplastic particles that could inadvertently affect your sexual
health, and possibly the functioning of your brain. Now that we know that these that's why I love nadsunder.com certified organic cotton. They are amazing. They fit really well. I've had my uh several pairs. I got like six or
a year. I travel a lot. Sit on airplanes and Ubers and stuff and they are super comfortable. But most importantly, my friends, they are protecting your body. the cheapest pair of boxers that I used to get because I only wear NADs under
lot of people in the health space are turning to this because we all recognize be serious about. It's not just avoiding, you know, plastic, you know, disposable coffee cups. we have to think about our clothing as well. So
definitely go to nadsunder.com/hit to save. They make amazing boxer briefs that you will absolutely love if you're a healthconscious male or have one in description below. Now getting back to the study. Really interesting. The
investigator say brain samples from dementia cases exhibited even greater micro and nanoplastic particle presence. These data they say are associated and do not establish causal roles for such particles affecting health. However, I
that if your brain is full of plastic, your brain is probably not going to function very well or optimally. So, it makes sense that we take mitigation strategies to reduce exposure to these
microplastic and nanoplastic particles. Uh, as you just heard, it's really place to start. Food packaging is another wonderful place to start. Not drinking out of plastic water bottles. Trying to bring your own stainless steel
mug when you go to a coffee shop or ask or request for the ceramic mug at the coffee shop. I mean, most places that I've been to are totally cool about doing that. Certainly not putting in uh you know, microwavable food wrapped in
plastic and the microwave and cooking with that. Uh heat and plastic are not a good combination. So, I think that's important. Okay. I also want to focus in on these images here. This is figure two. As you can see from these
microscopy images, there are numerous microplastic particles within um the preffrontal cortex brain tissue. So this is again not a conspiracy theory. This is not woowoo science. Um this is real evidence and it just corroborates with
what we already know about microplastic particle accumulation in the corateed arteries in I think the aorta there was one study and then we also have the penile tissue the placenta um breast milk I mean it's getting everywhere it's
time we really focus on this now in conclusion given the exponentially rising environmental presence of microanoplastic particles these data compel a much larger effort to understand whether micro and nanoplastic
particles have a role in neurological disorders or other human health effects. So, I think this is fascinating. What do you think? A lot of you might be asking, well, what do I do? I mean, let's say you've been eating fast food or you been
for a long time or even cooking food in the microwave and you're like, well, what do I do? I really don't know. I I think anyone who is very confident that they have all the solutions in terms of how to sort of detoxify or eradicate
these particle concentrations from your brain or your liver or kidneys um I I I will speculate here. I think going in the sauna is a great place to start. We the sauna is a great place to start. We know that heat in is a natural way to
sort of massage and activate our circulatory system and also our circulatory system and also our lymphatic system. So um we can help to through the urine or through the sweat which uh makes a lot of sense. We know
from the blood urine sweat study the so-called bus studies by Stephan Jennis at University of Alberta he's conducted a lot of studies finding that sweating and you know hot yoga and and sauna therapy and so forth is a great way to
um release heavy metals persistent organic pollutants and possibly microplastics. So, I think um you know, moving every day, that's part of why we exercise, not just to like burn calories and move our muscle and lower blood
glucose, but to also help detoxify and eradicate or eliminate these um harmful chemicals, even plastics from our bodies. So, that's what I would suggest.
filtration tech techniques that have been, you know, popular in in while that are coming uh to the US. That could be another uh tactic or strategy that people should consider. But I think it's important to know that we have like
liver, our kidney, and also our brain. And and this is really um something that we should be paying attention to. So let me know what your thoughts are in the tuning all the way to the very end, and we'll catch you on a future video down
we'll catch you on a future video down the road. Bye now.
