Veritasium just made a great video about the history of Teflon and related chemicals. I got claude to help me put here:
Teflon and PFAS Health Concerns
Teflon (polytetrafluoroethylene or PTFE) and related compounds have several health concerns:
Teflon itself
- The intact, long-chain PTFE polymer generally passes through the body without being absorbed, as you noted
- Not considered directly toxic when ingested in its stable form
Related harmful compounds
PFOA (C8) and PFOS:
- Used historically in Teflon manufacturing (not present in final product)
- Extremely persistent "forever chemicals" that bioaccumulate
- Associated with:
- Various cancers (kidney, testicular)
- Immune system impairment
- Thyroid disruption
- Reproductive issues
- Developmental problems
Shorter-chain PFAS (including C6):
- Introduced as "safer" replacements for C8 compounds
- Still very persistent in environment and bodies
- Growing evidence suggests similar health concerns to longer chains
- May be more mobile in environment
Heating concerns
Teflon breakdown:
- At normal cooking temperatures (below 500°F/260°C): minimal risk
- At high temperatures (above 500°F/260°C): Teflon begins to degrade
- At very high temperatures (above 660°F/350°C): releases toxic gases including:
- Fluorinated compounds
- Particulate matter
- Can cause "polymer fume fever" in humans (flu-like symptoms)
- Fatal to birds due to sensitive respiratory systems
Recommendations:
- Don't preheat empty pans
- Avoid high-heat cooking with Teflon
- Replace scratched or damaged Teflon cookware
- Consider alternatives like cast iron, stainless steel, or ceramic
I have never has success with stainless steel but I will definitely try the heat/wipe/fresh technique if I get a chance.
Like how many people were involved in this decision? Let's just call it "computer program".
