Food Contaminants Division, Food Safety Evaluation Department, National Institute of Food & Drug Safety EvaluationAbstract A food list representing the typical diet of Koreans was developed for a total diet study based on the 687 fooditems which appeared in the dietary intake data collected during the 2008 & 2009 Korea National Health & NutritionExamination Survey. Food items included in 90% of the cumulative intake, items with a consumption frequency of 5%or higher and items contributing to 80% of cumulative fat intake were considered first. From the resulting 165 food items,15 items were removed to avoid similar foods, while 10 distinct items were added to increase the efficiency of 'best-fit'mapping. Consequently, 160 items were selected as representative foods, which cover 90.93% of intake amount, 91.36%of energy intake and 89.05% of fat intake. Given that every food consumed by Koreans can’t be analyzed forcontaminants of interest, mapping other foods to the previously mentioned representative 160 foods is warranted becauseit enables a more comprehensive dietary exposure assessment that is close to reality.Keywords: food list, food contaminants, dietary exposure assessment, mapping
