[Differences in nutrient intake using different nutrient databases-- 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) 1986/87, extract of Bundeslebensmittelschlüssel (BLS) version 2.1, and extract 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 the revised BLS version 2.2 and mSFK, the differences in fluoride, iodine and dietary fiber intake data were markedly lower than found with the comparison of BLS 2.1 and mSFK; statistically significant differences no longer existed for the vitamins C and A (equivalents). As expected, using the mSFK data base with some missing fields for analytical data underestimation of nutrient intake could be shown for the trace elements 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.
