Abstract

The distribution of acrylamide in food items frequently consumed by Canadian adolescents was determined along with estimates of their contribution to the overall dietary intake of acrylamide. A total of 196 non-smoking adolescents (10-17 years old) were recruited in Montreal Island population, Canada. Participants were invited to fill out a 2-day food diary and a food frequency questionnaire over the last month. 146 samples of foods most frequently consumed by participants were analyzed for acrylamide contents. The highest acrylamide contents were measured in deep-fried french fries and potato chips (mean ± SD: 1053 ± 657 and 524 ± 276 ng/g respectively). On the basis of the 2-day food diary, median total daily intake of acrylamide was estimated at 0.29 μg/kg bw/d, as compared to 0.17 μg/kg bw/d on the basis of the food frequency questionnaire. These values are similar to those reported in comparable populations. Deep-fried french fries consumption contributed the most to daily acrylamide intake (50%) followed by potato chips (10%), oven-baked french fries (8%) and breakfast cereals (8%). Margins of exposure based on genotoxic benchmark dose limits were estimated to be low (≈<100) in high-consumer adolescents, indicating the need to continue efforts to reduce dietary acrylamide exposure.
