I was honored to have the opportunity to meet with @HHSGov @SecKennedy, and discuss common ground in addressing the #plastic #pollution crisis. We also discussed the crucial role of independent #science in identifying effects if plastic #chemicals. 1/

I recently gave a @TEDx @nyulangone talk on #plastics and human health—an area I’ve studied for years.
I was surprised to see that TED added a note to the video saying some of the health effects I discussed warrant further investigation. 1/ m.youtube.com/watch?v=2pwaWF…
I’m the first to say that more research is needed. It always is.
What the note risks obscuring is that my talk is rigorously grounded in peer-reviewed research, much of which I shared with TEDx in advance. 2/

Terrific to have Dr. @LeoTrasande join us at the Florida Department of Health grand rounds! Thanks for a great discussion about microplastics and emerging research on their health impacts in children and adults.

What do we know about the impact of plastics on human health?
The Florida Department of Health recently hosted a Grand Rounds presentation featuring environmental health expert Dr. @leotrasande, with opening remarks from @FLSurgeonGen Dr. Joseph A. Ladapo.
Watch the full presentation to explore the latest research, emerging health concerns, and actions that can help protect future generations of Floridians.
We also explored the path towards understanding how #microplastics and #nanoplastics interact with #chemicals to contribute to chronic disease. Insights from the @ARPA_H #STOMP program will provide a roadmap for sustainable #chemistry and other interventions to mitigate impacts.

Has U-1 been tested for toxicity? What is the compound? If it disrupts hormones or is toxic to reproduction, this is premature celebration.
Delighted to speak earlier today at a press conference leading up to the plenary on the final day of the #global #PlasticsTreaty here at @UN in #Geneva on behalf of @TheEndoSociety
Hey @nytimes @nytopinion get your facts straight - there are global data on mortality not just 32 countries. nytimes.com/2025/08/07/opini… we published global data on all countries & you even covered it. 1/
What is your problem with @nyulangone research that you can’t cover it properly? nytimes.com/2025/04/29/well/…

It’s clear from this @Reuters article that the @StateDept position plastics treaty is at odds with @HHSGov statements in support of the need to limit #chemicals in #food packaging and protect #kids from #chronic #disease.

It’s not bad politics but bad economics - taxing the consumer isn’t Pigovian.
The true power move companies can take is to improve discounts for consumers that bring their own stainless steel containers. Governments could offer incentives to companies that do it effectively.
Have your water supply tested for #PFAS before getting an expensive reverse osmosis filter. If it is high @theNASEM recommends getting testing for serum PFAS. Medical monitoring for chronic disease due to PFAS may be indicated.
Replying to @bryan_johnson
3/ Reduce PFAS exposure:
+ use a reverse osmosis or carbon-block water filter
+ avoid nonstick cookware (especially scratched pans)
+ skip fast food wrappers + microwave popcorn
+ ditch stain-resistant fabrics and furniture
+ use glass or stainless steel containers
These results are very compelling even as an n of 1. This should be studied with diet and other behavioral data (organic vs not, food packaging, plastic exposures). The microplastic data are uninterpretable because the methods used by the lab are opaque (trust me I have tried).
15 sessions of sauna dramatically reduced toxins in my body.
+ 65% drop in 2,4-D
+ 100% drop in MEP
+ 15% drop in MBP
+ 100% drop in MEHP (undetectable post sauna)
+ 56% drop in NAPR
+ 56% drop in HEMA
+ 100% drop in Perchlorate (undetectable post sauna)
After completing fifteen sauna sessions, each lasting 20 minutes at 200°F, led to a significant reduction in my environmental toxins, three went from being abnormally high to undetectable post sauna.
The lab is so opaque about its methodology that the results are uninterpretable - @bryan_johnson should be measuring phthalates, bisphenols and the like. The word scam comes to mind.
I’d be curious if @bryan_johnson attributes his 93% microplastic drop more to TPE or vigilance—avoiding processed foods, tap water, and plastic packaging.
I would credit avoidance most; it’s the first step we should all take.
While chemical detox via sauna (sweating) is definitely plausible (removes BPA, BPS, phthalates, and heavy metals), microplastic particle elimination via this method currently lacks support.
Most of this success is probably due to the practical implementation of strategies to avoid environmental sources of exposure versus specific elimination methods, though both likely play a role.
The press release oversold the results of this nonhuman study as clouding the health benefits of glass, when human studies reducing plastic contact in food have shown lower levels after intervention.
Water from glass bottles might contain up to 3x more microplastics than plastic bottles.
A recent study tested common beverages in France and consistently found glass bottles had the highest microplastic contamination, significantly exceeding plastic bottles and cans.
Beer topped the list, with small glass bottles averaging 134 microplastics per liter (MPs/L). Lemonades (112 MPs/L), colas (103 MPs/L), and cold teas (86 MPs/L) followed (all in glass), with far fewer MPs (1.5–2.4 MPs/L) in plastic bottles or cans.
Even plain bottled water wasn’t exempt. Glass bottles averaged 4.5 MPs/L. That's 181% higher than plastic bottles, which averaged 1.6 MPs/L.
Most surprising of all? The contamination wasn't from the glass itself. Rather, it came from the bottle caps. Researchers discovered that flakes of polyester-based paint on metal caps shed into the beverages. Uncleaned caps drove contamination levels as high as 287 MPs/L, while cleaning caps greatly reduced microplastic contamination by up to 70%.
It really seems that, as a consumer, there is no easy way out. So what can you do?
Filtered water from a reusable, BPA-free bottle remains your best choice to limit exposure. And recognize potential trade-offs. While glass may contain more microplastic particles, plastic bottles (especially when exposed to heat) generally test higher for PFAS and endocrine-disrupting chemicals like BPA and BPS.
