No 
A small set of whole foods maybe have energy,carbs and/or fiber assiged souce code 4, which is designated as "Imputed" data.
In addition, some manufacturers provide analytical data, though not many.
So in general, it's true, but not always.
You can find the USDA-SR17 documentation here:
http://www.nal.usda.gov/fnic/foodco.../SR17/sr17.html
And you can even download the database, in full, or abbreviated format. But you'll need the full format to find the nitrogen and CHO factors, and the source codes designated for each nutirent of every food item in the database.
