What type of foods does the era nomads eat?

Please clarify what you mean by "era nomads." Do you mean:

* Nomads from a specific historical era? For example, "nomads from the Bronze Age" or "nomads of the Mongol Empire."

* Nomads from a specific geographical region? For example, "nomads of the Mongolian Steppe" or "nomads of the Arabian Peninsula."

* Nomads in general, regardless of era or location?

Knowing the specific context will allow me to give you a more accurate and relevant answer.
