Microplastics, on tape

The researchers who found plastic in our blood and brains, the podcasts that got them talking, and the explainers that make the science make sense. Watched, vetted, and worth your time.

Huberman Lab · 2024

The Effects of Microplastics on Your Health

Dr. Andrew Huberman — Stanford neurobiologist and host of the Huberman Lab podcast

Huberman's solo deep-dive is the best single starting point on this topic: what microplastics and nanoplastics actually are, how they get into us, and a concrete, non-alarmist checklist for cutting exposure.

  • Microplastics range from 1 micron to 5mm; nanoplastics are smaller and can cross barriers like the gut and blood-brain barrier
  • Biggest wins: stop heating food in plastic, swap plastic storage and water bottles for glass or stainless steel, and filter tap water
  • Endocrine disruptors like BPA, BPS and phthalates are the specific chemicals to worry about, not just the particles themselves

The long conversations

Podcasts that give the researchers room to actually explain.

The Joe Rogan Experience · 2026

Plastics, Hormones & Falling Fertility

Dr. Shanna Swan — Environmental epidemiologist and author of 'Count Down'

Swan's 2026 return to Rogan brings the reproductive-health science to a huge mainstream audience. A long, wide-ranging conversation on how everyday chemical exposure is reshaping fertility.

  • Sperm counts have fallen roughly 50% over recent decades, a trend Swan ties to endocrine-disrupting chemicals
  • Prenatal exposure windows matter most, meaning what a pregnant person is exposed to shapes the child's later hormone health
  • Reducing plastic food contact and fragranced consumer products is the most actionable individual response

Modern Wisdom · 2025

The Truth About Microplastics

Dr. Rhonda Patrick — Biomedical scientist and founder of FoundMyFitness

Patrick is meticulous about separating what the evidence shows from what's hype, which makes this the most citation-heavy episode in the set. A calm, rigorous tour through the research on plastics and the body.

  • Not every scary headline holds up; Patrick weighs study quality before drawing conclusions on health harm
  • Heat plus plastic is the key exposure multiplier: microwaving and hot liquids leach far more than cold contact
  • Sweating, sauna use and fiber-rich diets are discussed as plausible routes to help the body clear certain chemicals

ZOE Science & Nutrition · 2025

Microplastics in Your Brain, Heart & Blood

Dr. Sabine Donnai — Longevity physician and clinician

ZOE's tightly produced episode focuses on where plastic particles have been found inside the human body and what a realistic personal 'plastic detox' looks like. Accessible without dumbing things down.

  • Plastic particles have been detected in human blood, organs and brain tissue in recent studies
  • Kitchen habits (plastic chopping boards, non-stick pans, plastic kettles) are underrated everyday sources
  • Focus on the changes with the biggest payoff rather than trying to eliminate all plastic at once

From the researchers

Talks and lectures by the people doing the measuring.

Big Brains (University of Chicago podcast) · 2025

How Microplastics Are Invading Our Bodies

Dr. Matthew Campen — Regents' Professor of Pharmaceutical Sciences, University of New Mexico — led the 2024–25 studies that quantified microplastics in human brains

The researcher behind the headline-making human brain study walks through what his lab actually found — and is refreshingly candid about what we still don't know. A calm, first-hand account of the most talked-about microplastics finding of the decade.

  • Campen's team measured roughly a plastic spoon's worth (about 7 grams) of micro- and nanoplastics in the average human brain
  • Plastic concentrations in brain samples rose about 50% between 2016 and 2024
  • Most particles are nanoscale shards from decades-old plastic degrading in the environment, likely arriving via food

Beyond Plastics webinar · 2023

Plastics' Impact on Human Health

Dr. Philip Landrigan — Pediatrician and epidemiologist, Boston College — led the Minderoo-Monaco Commission on Plastics and Human Health

A full hour with one of the world's leading environmental-health physicians, laying out the Minderoo-Monaco Commission's findings on how plastics affect health at every stage of their life cycle. Long, but this is the definitive plain-language briefing from the person who ran the numbers.

  • Plastics harm health across their entire life cycle — production, use, and disposal — not just as litter
  • Plastic-associated chemicals like phthalates and BPA are linked to billions of dollars in disease burden annually
  • Children and fetuses are the most vulnerable populations, which is why Landrigan pushes for a global plastics treaty

TEDxBeaconStreet · 2020

Microplastics: Knowns, Unknowns & Actions

Dr. Sheila Hemami — Engineer (PhD, Stanford); director of strategic technical opportunities at Draper; former engineering professor at Cornell and Northeastern

An engineer's honest sorting of the microplastics evidence into what we know, what we don't, and what's worth doing anyway. A good antidote to both doom-scrolling and complacency — Hemami is precise about uncertainty without using it as an excuse for inaction.

  • We reliably know microplastics are in our water, food, and air; the dose-harm relationship in humans is the big open question
  • Personal actions worth taking now: fewer single-use plastics, tap over bottled water, natural-fiber clothing
  • Individual choices matter but scale only through policy and product redesign

Generation Sea Change · 2023

The Godfather of Microplastics

Prof. Richard Thompson OBE — Marine biologist, University of Plymouth — coined the term 'microplastics' in his 2004 Science paper

A short, beautifully shot profile of the scientist who literally named the problem. Thompson explains how a hunch about tiny fragments on British beaches became a whole field of research — and why he's more interested in fixing the system than in panic.

  • Thompson's 2004 paper 'Lost at Sea: Where Is All the Plastic?' coined the word 'microplastics'
  • Most microplastic in the ocean comes from larger items fragmenting, not from products designed small
  • Thompson argues the fix is upstream — better design and policy, not just beach cleanups

TED-Ed · 2026

3 Surprising Ways Microplastics Enter Your Body

TED-Ed — TED's animated education studio, scripted with subject-matter reviewers

TED-Ed's signature animation tackles the three main routes plastic takes into your body — the air you breathe, the things you touch, and what you eat and drink. The clearest six-minute primer on exposure pathways you'll find anywhere.

  • Micro- and nanoplastics enter the body through air, skin contact, and food and drink
  • Indoor air and household dust are underappreciated exposure routes
  • The smallest particles can cross into tissues and interfere with the body's normal processes

The explainers

The science in minutes, not hours — well made, well sourced.

The Peter Attia Drive · 2025

Five Ways to Reduce Your Microplastic Exposure

Dr. Peter Attia — Physician (MD, Stanford; trained at Johns Hopkins) focused on longevity and preventive medicine

A physician's ranked, no-nonsense list of the exposure reductions that actually move the needle — heat plus plastic is the enemy, and your kitchen is where most of the wins live. The practical companion piece to all the scarier science above.

  • Never heat food in plastic — microwaving is the single biggest particle-release event in most kitchens
  • Swap plastic cutting boards, containers, and bottles for wood, glass, and stainless steel
  • Prefer tap (filtered) water over bottled, and be wary of plastic-lined coffee cups and kettles

ABC 7.30 · 2025

How Worried Should We Be About Microplastics at Home?

Dr. Norman Swan — Physician and ABC health journalist

A physician-journalist takes the microplastics story indoors, asking how much of our exposure actually comes from the home. Short, current, and practical for anyone auditing their own space.

  • The home can be a major exposure zone via synthetic textiles, dust, and plastic kitchenware
  • Microplastics have been found in human blood and brain tissue, though health effects are still being studied
  • Simple steps like ventilation, less synthetic fabric, and avoiding heated plastic reduce household exposure

Kurzgesagt – In a Nutshell · 2018

How Humans Are Turning the World into Plastic

Kurzgesagt — Animation studio; this episode was produced in collaboration with UN Environment's Clean Seas campaign

The classic Kurzgesagt treatment: how a miracle material became a planetary management problem, from the chemistry of polymers to the microplastics now circulating through food webs. Still the best-animated on-ramp to the whole topic.

  • Humanity has produced billions of tonnes of plastic, and most of it still exists in some form
  • Plastic doesn't biodegrade — it fragments into ever-smaller microplastics that move up the food chain
  • The biggest leverage is in packaging, waste systems, and design, not consumer guilt

FRONTLINE · 2020

Plastic Wars

FRONTLINE / NPR investigative team — PBS FRONTLINE investigative documentary unit

This FRONTLINE and NPR investigation is the essential 'why recycling didn't save us' story, showing how the plastics industry promoted recycling while knowing most plastic would never be recycled. Context that reframes the whole problem.

  • Industry documents show companies doubted plastic recycling would ever work at scale, even as they marketed it
  • The recycling symbol gave consumers false confidence and helped normalize single-use plastic
  • Explains why reducing plastic at the source matters more than sorting it after the fact
