DIFFERENCES IN NUTRIENT INTAKE WHEN USING DIFFERENT NUTRIENT DATA-BASES - AN EXAMPLE

Mean dietary intake calculated from 25 7-day-food records by means of the three nutrient data bases modified Souci/Fachmann/Kraut (mSFK) 198 6/87, extract of Bundeslebensmittelschlussel (BLS) version 2.1, and ex tract of BLS version 2.2 revealed comparable results only for four of 27 nutrients considered. The greatest deviations were found for zink, fluoride, iodine, vitamin D, vitamin C, and dietary fiber. Comparing t he revised BLS version 2.2 and mSFK, the differences in fluoride, iodi ne and dietary fiber intake data were markedly lower than found with t he comparison of BLS 2.1 and mSFK; statistically significant differenc es no longer existed for the vitamins C and A (equivalents). As expect ed, using the mSFK data base with some missing fields for analytical d ata underestimation of nutrient intake could be shown for the trace el ements zink, fluoride and iodine. With regard to the given results of the investigated group, care has to be taken with some nutrient intake data gathered by means of BLS 2.1, too.
