Assessment of acrylamide intake of Spanish boys aged 11-14 years consuming a traditional and balanced diet

Abstract

Acrylamide is a toxic and potentially cancer causing chemical formed in thermally treated foods, especially in carbohydrate rich. New dietary habits acquired by adolescents, increasing snacking and fast food consumption, lead to a high acrylamide intake, since the composition of these meals and their processing promote its appearance. This study investigated acrylamide daily exposure in a group of Spanish male adolescents (11–14 years) consuming a balanced diet based on their food preferences but reducing snacking and fast food, aimed to determine whether acrylamide exposure was reduced by the consumption of a traditional diet. Acrylamide content of main dishes was analyzed and input per serving calculated. The Spanish potato omelette and the grilled loin of pork with fried potatoes presented the highest levels of acrylamide (128 and 111 μg/kg respectively), followed by different meals also containing potatoes or cereal derived products. The acrylamide total intake was estimated at 0.534 μg/kg body weight/day, where the highest percentage was provided by the breakfast (31.66%), the afternoon snack being the lowest contributor (16.19%). These results indicate consumption of a balanced and traditional diet, besides the well known beneficial effects on health, can also moderate acrylamide exposure and thus its possible long-term toxicological effect.
