Research data showed that elevated consumption of grilled
meat might cause cancers of colon, liver, lungs and breast in human
beings (Sugimura et al., 2004) but some others have a contradictory
viewpoint that these cancers are not only linked with the presence
of HAAs (Barrett et al., 2003) because well-done cooked meat has
several other carcinogenic compounds such as polycyclic aromatic
hydrocarbons, N-nitroso compounds, lipid peroxides and other
pro-oxidant compounds. So the carcinogenic potency of these
grilled and other well-done cooked meats is not only related to
HAAs but also to the complex mixtures of these genotoxic compounds
(Cross & Sinha, 2004).
