Ancestrally, the Eituhel descended from a fey race that was strictly vegetarian, but upon finding themselves outside the comfort of their home realm, they eventually learned to consume meat in dire circumstances and became functionally omnivorous after years of evolution. Despite this, modern Eituhel only eat meat either rarely or occasionally, tending to boast a more vegetarian diet.

These diets more specifically involve a wide range of flowers, fruits, herbs, nuts, seeds, and nectar, making a source of sugars, starches, and fiber a needed staple for Eituhel to fuel their explorative lifestyles. Their stomachs are specially designed to efficiently process nutrients from plants, leaving them fuller for longer and omitting the need to consume protein often. If a source of protein is needed, they typically ingest animal products like eggs and dairy, but this can be seldom.
