The only source currently for all data is the USDA's Food Data Central. I'm planning on adding more nutrient data sources in the near future.

Really. Because it looks less useful than its source.

If I search for Apple on food central, I get offered different types of Apple, like Fuji, honeycrisp, etc. with nutripedia I just get raw and cooked, which are within each type on food central.

In addition, nutripedia has a bunch of what looks like AI written text that is not particularly useful.

Writing an AI generated wrapper around something is not enough to be interesting. What do you see as your value add?
