Hi,

* As usercvapp mentioned, I'm fetching nutrition data from USDA (https://fdc.nal.usda.gov/).

* I would say yes, USDA is the gold standard for food and nutrition data.

* Each ingredient is matched with foundational and legacy foods (not pre-packaged or branded) so if the matching is right the values are accurate.

* Final nutrition label relies on specific quantity and unit of each ingredient extracted, which you can edit to ensure the best estimation accuracy.
