That's what OpenNutrition does. However, in many cases, there is no publicly accessible "non-AI data" source to refer to. OpenNutrition tries to bridge the gap, using the public data when available, and providing additional inferred data to fill in the gaps. For "red beans" and "rice", OpenNutrition provides a long list of foods with full citations in public databases. See the "References" section where you can click through to the source material.
