Heavily charring meat and other foods at high temperatures produces heterocyclic amines and polycyclic aromatic hydrocarbons, which are classed as carcinogenic or probably carcinogenic compounds.

Is it true that heavily charring meat and other foods at high temperatures produces heterocyclic amines and polycyclic aromatic hydrocarbons, which are classed as carcinogenic or probably carcinogenic compounds?

Unclear. Two peer-reviewed reviews report that high-temperature meat cooking generates heterocyclic aromatic amines and polycyclic aromatic hydrocarbons, and one links these to DNA-reactive metabolites and cancer. Neither item addresses charring specifically nor states the carcinogen classifications the claim asserts, so the evidence covers only part of the claim.
