Bees, bugs and fish.

When it comes to food and animal products, Levis society is weird. But it is also not a monolith. The main drive of the people of Levis is that everything you consume must affect the cycle of life as little as possible.
Thus the key feature of most places is a mandatory personal garden. But some creature-kin, demons and twinform require meat in their diet, and so they must find alternatives to the norm. Now carnivorous people in Levis are often looked down on for their diet when it comes up in conversation .
Eggs and egg based products are a great taboo, as they take the start of a cycle and end it prematurely, no matter if they haven't been fertilised or not. Insects are seen as lesser parts of the ecosystem, however many sections of the continent where food is in over-abundance see consuming insects as tantamount to eating meat - though many a southern and central Levis person has been known to travel to Solaris and the like for the exotic wrongness of it all.
Fish is often seen as meat, although fishing is seen as more culturally acceptable across Levis, the towns lining Oceanus doing so most frequent and having the most stringent guidelines on how to do so. Export up the rivers of fishing goods on frozen barges is possible, but those who partake deeper inland are seen as weird. Honey is seen as acceptable, as long as you care for the hive with access to extra flowers and a regular supply of nutrient rich water.
