Food List for the Study of Dietary Intakes of Chemical Substances in Japan

Abstract

We investigated the details of the food list for the study of dietary intakes of chemical substances in Japan.
1) The food list was fundamentally based on the National Survey of Nutrition and was completed with other data such as the Family Income and Expenditure Survey and the Statistical Yearbook of Ministry of Agriculture, Forestry, and Fisheries, and so on.
2) To correct the seasonal deflection in the National Survey of Nutrition data, we calculated the “Seasonal correction factor” with the monthly data of the Family Income and Expenditure Survey, and established “Corrected food consumption. ”
3) If subdivision of the food categories were necessary, we broke it down into several food items according to the proportion of their production data in the framework of “Corrected food consumption. ”
This food list may be applicable to the assessment for the dietary intakes of naturally occurring dietary constituents as well as chemical contaminants and food additives.
