Episode notes
Measurement Methods May Inflate Estimates
- Analytical methods like pyrolysis-GC/MS can misidentify brain fats as polyethylene, inflating plastic estimates.
- Reported 'spoonful' and diet plastic numbers may be substantial overestimates.
Filter Your Drinking Water
- Reduce microplastic intake by avoiding bottled water and preferring filtered tap or glass bottles.
- Using reverse osmosis or quality filters gives a high return on effort to lower exposure.
Stop Heating Food In Plastic
- Avoid heating food in plastic and switch to glass storage to prevent leaching of plastic chemicals.
- Use glass Tupperware and avoid microwaving plastic containers.
