A comparative study of two microcomputer nutrient data bases with the USDA Nutrient Data Base for Standard Reference.
The results of this investigation show that when direct comparisons are made between the USDA NDB and microcomputer data bases (avoiding the confounding factors of coding judgment and the differences between older and newer USDA nutrient data), differences still can exist. N3 and FP chose to seek out alternate data when the USDA NDB provided no data for a certain nutrient. FP chose to use a large number of additional sources to supplement USDA Handbook No. 8. Although the USDA NDB was very complete for all nutrients listed except for vitamin E/total and copper, gaps are likely to continue to exist because the USDA NDB is and will be in continual revision as an increasing number of nutrients are reported for an ever-growing food supply. Therefore, in accordance with established local needs, the dietitian has the responsibility both for knowing the sources used in the microcomputer nutrient data base and for making sure that reported results are reasonable.
