Assessment of dietary acrylamide exposure in children attending Spanish school canteens using the duplicate diet method
Acrylamide is a carcinogenic chemical contaminant formed in heat-treated foods. In this study, a duplicate diet method was used to evaluate the acrylamide content of foods/meals served at breakfast and lunch in two Spanish school canteens. The dietary acrylamide intake in students was estimated within lower bound (LB) and upper bound (UB) scenarios. Biscuits exhibited the highest acrylamide values, exceeding the benchmark level established by the European Regulation 2017/2158 (350 μg/kg), followed by main courses such as stews, side dishes and bread. In the LB scenario, breakfasts accounted for the major contributors to the daily acrylamide intake (73.3%). However, lunches were the main responsible in the UB scenario (65.4%). Acrylamide exposure was estimated for three age ranges: 3-5y pre-school children (0.59 and 0.92 μg/kg body weight/day), 6-9y children (0.43 and 0.67 μg/kg body weight/day) and 10-12y early adolescents (0.28 and 0.44 μg/kg body weight/day). Margins of exposure for neoplastic effects ranged between 144 and 1026, which is below the reference of 10,000, indicating a health concern. The findings reveal that any diet, even one that is balanced, varied and contains foods low in acrylamide, involves an additive exposure to the contaminant that should be considered when conducting acrylamide exposure risk assessments.
