Citrus County Chronicle Research has shown that when any kind of meat, poultry or fish is cooked at high temperatures, especially when well-done or charred, cancer-causing compounds called heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are formed.

Atlanta Black Star But cooking at high temperatures can activate heterocyclic amines (HCAs), chemical compounds released by charring the protein in meats that can be carcinogenic. The unhealthy compounds develop during the browning process, or Mallard reaction.

Doctor Tipster However, precedent studies have shown that meat is responsible for the production of chemical compounds , such as N-nitroso compounds and heterocyclic amines, that are responsible for damaging the colon cells. In theory, this is the one of the processes  ...
