Key Findings
Significant reductions in multiple plastic-associated chemicals were seen in the low-plastic group.
This shows that diet and daily habits are major drivers of exposure—especially through food contact materials.
However, exposure was not eliminated, indicating that plastics are pervasive in the environment and hard to fully avoid.
My addition: How to improve elimination of ingested plastic
Dietary fiber (especially soluble fiber)
Examples: psyllium, pectin, beta-glucan, resistant starch
Mechanism:
Forms viscous gel → traps particles
Increases stool bulk → faster elimination
Can bind bile → reduces recirculation
Evidence:
Natural fibers physically trap microplastics via porosity + electrostatic interactions
Fiber is well-established to increase toxin excretion in humans
