The following factors are considered in deciding whether to add a nutrient or other food component to the database:

• Scientific Interest: Is there demand for it? If there is a nutrient or food component you’d like added to the database please let us know(ndsrhelp@umn.edu).
• Availability of Food Composition Information: Is there analytic composition information available for a significant proportion of core foods in the NCC Food and Nutrient Database?
• Quality of Analytic Data: Is the analytic information available of sufficient quality (e.g., obtained using appropriate analytic methods) for use in assigning values to foods in the NCC Food and Nutrient Database?
