A study compared the nutrient databases of 2 widely-used, extensively-developed microcomputer nutrition software programs ("Nutritionist III" (N3) and "The Food Processor" (FP)) with the USDA Nutrient Data Base (NDB) using a food record of 20 foods (100-g portions). Calories, protein, and fat values from N3 and FP were within 3% of USDA NDB values. FP had 6 nutrients (carbohydrate, Ca, Fe, K, Cu, total vitamin E) and N3 had 2 nutrients (Cu and total vitamin E) that differed by over 10% from USDA NDB values. The absolute average difference from USDA NDB values was 12.6% for FP and 3.4% for N3. The reasons for these differences are discussed.(wz).
