In Episode 289 of the Fit Father Project Podcast, Dr. Anthony Balduzzi takes a deep dive into one of the most urgent and underappreciated health threats of our time: microplastics and nanoplastics.
While most people know to avoid drinking from single-use plastic bottles, this episode goes far beyond the obvious.
Dr. A explains the critical difference between microplastics and nanoplastics, breaks down the five mechanisms by which plastic damages the body, and exposes the hidden sources of plastic exposure most people never think about, including tea bags, table salt, cookware, clothing, seafood, and grocery store receipts.
He also covers what the latest research says about how plastic is showing up in human blood, brain tissue, arterial plaques, and even reproductive organs, and what you can realistically do about it.
If you're serious about protecting your hormones, your heart, your gut, and your long-term vitality, this episode gives you the research-backed knowledge and practical steps to start reducing your plastic burden today.
It is also a must-share episode for parents and grandparents who want to protect the next generation from a growing and largely invisible threat.

Key Takeaways
- Microplastics vs. nanoplastics: size determines where they go in the body and how much damage they cause
- Nanoplastics are 70 times smaller than the width of a human hair and can cross the intestinal wall, enter the bloodstream, and reach the heart, brain, and reproductive tissue
- A Columbia University study found that 90% of plastic particles in bottled water are nanoplastics, the most dangerous kind
- The five mechanisms of plastic harm: endocrine disruption, oxidative stress, chronic inflammation, gut microbiome disruption, and cellular senescence
- BPA and phthalates act as xenoestrogens, blocking natural hormones, lowering testosterone in men, worsening perimenopausal symptoms in women, and suppressing thyroid function in both sexes
- A 2024 New England Journal of Medicine study found that patients with microplastics in their arterial plaques had a 4.5 times higher risk of heart attack, stroke, and death
- Hidden sources most people miss: plastic-mesh tea bags, table salt, polyester clothing, nonstick cookware, larger fish, and BPA-coated thermal receipts
- Himalayan pink salt tested with the highest microplastic load of any salt in a 2023 Australian study; Redmond Real Salt from Utah is currently the cleanest known option
- The body can eliminate microplastics through fiber-rich stool and excrete plasticizer chemicals like BPA and phthalates through sweat and sauna
- There is currently no proven method to remove embedded nanoplastics from tissues; reducing total lifetime exposure is the single most important strategy
