PAHs (polycyclic aromatic hydrocarbons — grilled meats, air)
Toxins · Combustion carcinogen
Moderate priority
Bottom line
Read Off Label rates PAHs (polycyclic aromatic hydrocarbons — grilled meats, air) a MODERATE avoidance priority (5.3/10) based on strong evidence of moderate harm magnitude and low-moderate dietary exposure prevalence.
Marination reduces PAH formation substantially (vinegar/citrus/rosemary components).
The intervention here is reducing exposure, not adding a compound.
What this is
Marination reduces PAH formation substantially (vinegar/citrus/rosemary components). Cooking method matters more than meat quality. Also formed when fat drips onto hot surfaces — vertical grilling or foil-wrapping reduces exposure. Airborne PAH from nearby combustion sources is a separate exposure route.
Mechanism
Formed during incomplete combustion — grilled/charred meat, diesel exhaust, tobacco smoke, industrial combustion; benzo[a]pyrene is prototype IARC Group 1 carcinogen
Dose & route
Don't char meat; marinate (polyphenol protection); lift meat off direct flame; sous vide / indirect grilling
