Cutting plastics: simple swaps against endocrine disruptors
September 29, 2026 · 25 min read
Shanna Swan, Natalie Crawford, William Li and Huberman's microplastics episode identify phthalates, BPA and microplastics in food, water and packaging as hormone disruptors, and list easy swaps. Reducing exposure is cheap and protects fertility and hormone health.
The rules, numbers and steps worth keeping in front of you.
- Main culprits: phthalates, bisphenols and the micro- and nanoplastics that carry them.
- Main routes: food, drinks, packaging, cookware and scented products.
- Shanna Swan: phthalates in early pregnancy were linked to less masculinized baby boys.
- Swan: sperm counts fell about half in 50 years; she concludes the cause is environmental.
- Go fragrance-free: lotions, soaps, deodorant, detergent, shampoo, especially for children.
- Never heat food or drink in plastic; microwave safe only means it will not melt.
- Drink and store in glass, ceramic or unlined stainless steel.
- Avoid canned food, especially fatty, acidic soup; BPA-free may mean a similar substitute.
- Replace non-stick pans with seasoned iron, cast iron or ceramic.
- Buy loose produce and bulk goods in your own jars; often cheaper.
- Andrew Huberman: filter tap water, choose non-marine salt, decline paper receipts.
- Phthalates and bisphenols clear within hours; exposure before birth cannot be reversed.
- Evidence is strongest for the chemical additives, weaker for the plastic particles themselves.
- Pregnant, trying to conceive or worried about hormones: see an obstetrician, urologist or reproductive endocrinologist.
This is the short form. The full insight has every expert's reasoning, their own words and the sources.
