When mappings are not found
While most ingredients will have mappings, occasionally you'll find that the nutritional database doesn't have a good match. When this happens, the nutritional information for the recipe has to be calculated without the ingredient. The USDA does update the database often, though, so at some point all of the ingredients could be available for your calculations. You'll be able to get this updated information simply by downloading and reinstalling a new version of the Nutrition plug-in, when it's available.
