Episode 83. Microplastics in Our Food and Body: Cutting Boards, Microwaves, More

Sep 19, 2023

Dr. Roger Seheult discusses the prevalence of microplastics in our food and body, including the release of microplastics from plastic containers during microwaving. They explore the presence of microplastics in containers, the effects of plastic exposure on kidney cells, the presence of microplastics in human food from cutting boards, and the detection of microplastics in human heart and surrounding tissues. They also discuss the issue of harmful chemicals in consumer products and initiatives to eliminate toxic substances from the market.

Quick takeaways

Microwaving certain plastics can release millions of microplastic and nanoplastic particles, highlighting potential health risks.

Consumption of microplastics in humans through eating, drinking, and breathing is estimated to be in the range of 39 to 52,000 particles, indicating widespread exposure to microplastics.

Plastics in Microwaved Products Release Microplastics and Nanoplastics

A recent study examined the release of microplastics and nanoplastics from plastic containers and reusable food pouches when microwaved. It was found that within three minutes of microwave heating, one square centimeter of plastic area could release as many as 4.22 million microplastic particles and 2.11 billion nanoplastic particles. The study also revealed that different types of containers and varied temperatures had an impact on the amount and size of particles released. These findings highlight the potential health risks associated with microwaving certain plastics.
