383: Endocrine Disruptors, PFAS & Hidden Weight Gain | Leonardo Trasande | Leonardo Trasande
Plastics shift the conversation from invisible risks
Micro/nanoplastics now appear in human tissues, energizing policy and parent action. The core claim: endocrine-disrupting chemicals and plastics change metabolism, inflammation, and disease risk—so replacing plastics with “bioplastics” isn’t automatically safer.
PFAS guidance turns exposure into actionable tiers
National Academy of Sciences framing makes PFAS measurable and interpretable: green (<2 ng/mL), yellow (2–20), red (>20). Red implies filtering water/air and more repeat thyroid/certain cancer monitoring—elevating prevention from vague avoidance to risk-stratified steps.
Serum drops aren’t the whole body-burden story
The mechanism of benefit is slower and deeper than blood testing: chemicals leave serum quickly, but cellular/tissue changes (and downstream outcomes like chronic disease or preterm birth risk) can take months–years. Therefore, focusing only on lab “numbers” can mislead.
