Episode description
- Plastic cutting boards shed microplastics during routine food prep, contributing to increased plastic ingestion that accumulates in organs like the brain and reproductive tissues over time
- Research shows knife pressure releases hundreds of plastic fragments per cut, many embedding into food tissue and remaining even after rinsing or cooking
- Older, heavily grooved boards release more microplastics, as repeated knife strokes and surface wear accelerate abrasion and contamination during everyday meal prep
- Replacing plastic boards with wood, bamboo, or glass reduces microplastic exposure, while proper cleaning and timely replacement help limit bacterial and chemical risks
- Beyond cutting boards, reducing exposure to microplastics requires filtering water, avoiding plastic packaging, choosing natural fabrics, and addressing hormone disruption caused by estrogen-mimicking plastic chemicals
