Episode description
- A recent Osteoporosis International review summarized multiple studies showing that microplastics have been detected in human bone tissue, where they disrupt bone cell activity, trigger inflammation, and weaken structural integrity
- Laboratory and animal studies show microplastics accelerate osteoclast activity and alter bone microarchitecture, linking environmental plastic exposure to rising rates of bone fragility and dysplasia
- Microplastics are not limited to bone; previous research has also detected them in the bloodstream, brain, placenta, heart, lungs, liver, kidneys, and reproductive tissues
- Ultrafine combustion particles (UFPs), which are smaller than microplastics, pose an even greater threat due to the vastly higher levels of exposure you face each day
- Lower your daily microplastic exposure by switching to natural fabrics, filtering your air and water, avoiding plastic containers, and replacing plastic kitchen tools with safer materials
