The Effects of Microplastics on Your Health & How to Reduce Them
In this episode, I explain what microplastics are, their prevalence in the human body and environment, and their common sources, as well as their potential negative health impacts. I provide practical strategies for limiting exposure to microplastics, nanoplastics, and endocrine disruptors such as bisphenol-A (BPA), bisphenol-S (BPS), phthalates, and PFAS.

Introduction to Microplastics
This episode introduces microplastics, defining them by size and highlighting their pervasive presence in everyday life. The speaker emphasizes the importance of understanding their potential health impacts, while also noting the ongoing research and the need for a balanced perspective, avoiding alarmism.
The Scale of the Microplastic Problem
The discussion delves into the widespread presence of microplastics and nanoplastics, addressing conflicting reports on ingestion amounts. It highlights their detection in various human tissues, including the brain, testes, and placenta, raising concerns about their ability to penetrate critical biological barriers.
Sources of Microplastic Exposure
This section details common sources of microplastic exposure, including bottled water, sea salt, canned goods, paper cups, and cookware. It emphasizes the need to switch to glass or stainless steel containers, consider water filtration, and opt for non-plastic alternatives to reduce intake.
Health Impacts: Hormones and Reproduction
The discussion shifts to the health impacts, focusing on endocrine disruption from chemicals like phthalates, BPA, and BPS. It highlights their potential to affect hormone levels, reproductive health, and sperm quality, with correlative data suggesting links to reduced testosterone and sperm counts.
Detoxification and Removal Strategies
This segment focuses on the body's natural detoxification mechanisms and how to support them. Strategies include consuming cruciferous vegetables, increasing fiber intake, and promoting sweating through heat exposure, all aimed at aiding the body in processing and eliminating harmful substances.
Reducing Exposure: Practical Tips
Practical advice is offered to minimize microplastic exposure, including avoiding plastic packaging, using reusable containers, choosing safer cookware, and reducing clothing turnover. These lifestyle adjustments aim to lower overall plastic intake and environmental impact.
Other Sources and Neurodevelopmental Concerns
The discussion covers additional sources like microwave popcorn and toothpaste, and notes variations in PFAS levels in sparkling water brands. While cautioning against definitive links to neurodevelopmental disorders, the importance of minimizing exposure, especially during pregnancy, is stressed.
Conclusion and Future Directions
The episode concludes by reiterating that while eliminating microplastics is impossible, reducing exposure and supporting the body's natural detoxification processes are vital. The speaker encourages informed choices, highlights the importance of supporting the podcast, and mentions his upcoming book.
