*It is important to note that although there are commercial databases that contain more foods than the NCC database, the nutrients available in these databases are generally limited to those included on the Nutrition Facts panel.
As a result, non-label nutrients of interest such as caffeine, carotenoids, and individual fatty acids such as omega-3s are generally not included in these databases. Also, the completeness of the data in commercial databases tends to be low for a number of nutrients of high interest, rendering these databases of limited use in research and many other applications. As an example, although the ESHA database includes over 50,000 food items the level of completeness is low for some nutrients (e.g., 60% complete for potassium, 48% complete for zinc, and 20% complete for vitamin D).
