What nutrient database does the Diet*Calc software use?
The nutrient database for the DHQ was created using a data-driven method derived from national dietary data from USDA’s 1994-96 Continuing Survey of Food Intakes by Individuals (CSFII). The method is documented in: Subar AF, Midthune D, Kulldorff M, Brown CC, Thompson FE, Kipnis V, Schatzkin A. An evaluation of alternative approaches to assigning nutrient values to food groups in food frequency questionnaires. Am J Epidemiol 2000;152:279-86. Carotenoid values were added using the nutrient database from the University of Minnesota’s Nutrition Data Systems for Research, which is primarily based on values from the US Department of Agriculture. The file format required for Diet*Calc is detailed in the Diet*Calc Help System. The help system is installed with the Diet*Calc software (see Download the Diet*Calc Software).
