For visitors' convenience, we have created different web apps to make it easier for them to find exactly what they look for.
Foods with Specific Nutrients
For visitors who want to find foods that contain a specific nutrient and how much of it.
Only foods where the nutrient is present are listed in these databases.
Foods without Specific Nutrients
For visitors who want to find foods that do not have a specific nutrient.
Only foods where the nutrient is absent are listed in these databases.
Nutrient Content of Foods
These databases show a nutrient's content in foods regardless of whether the nutrient is present or absent, so long as nutrient data are available.
Visitors who wonder why bother separating databases into haves and have-nots should find these useful.
