Real and open nutritional datasources exist: https://support.cronometer.com/hc/en-us/articles/36001823947...
OpenNutrition uses many of the same open datasources included there, including USDA SR, CNF, AUSNUT, etc. The other datasources are licensed and not open, and I do not use those so that I can deliver a free app with a more generous set of features.
