Carcinogenic and neurotoxic risks of acrylamide consumed through bread, kaak, toast, and crackers among the Lebanese Population.

The present study deals with the assessment of acrylamide levels, dietary intake and toxicity associated with food products which constitute the main components of a Lebanese breakfast including bread, crackers, toast and kaak. Quantification of acrylamide levels was performed on a UPLC-MS/MS spectrometer and upon correlation with the results of a community survey, the carcinogenic and neurotoxic risks associated with the dietary intake of acrylamide were calculated. The average exposure to acrylamide from the investigated dietary products was found to be 5 times higher than the intake of 0.08 μg/kg-bw/day, as estimated by the NFCA (Norwegian Food Control Authority) and 3 times higher than the intake of 0.14 μg/kg-bw/day as set by the WHO (World Health Organization). MOE and MOE (Margin of Exposure for neurotoxic and carcinogenic risks) values ranged between 290 and 556, and between 449 and 861 respectively. Kaak, Crackers, and Toast appear to pose no neurotoxic or carcinogenic risk of concern among the entire population as well as the individual age groups. French bread and Lebanese bread pose different levels of carcinogenic risk among the entire population as well as various age groups. The results also indicate that 24% of children, 4% of young adults and 8% of adults are at both neurotoxic and carcinogenic risks.
