Of the divisions between the sentient species of Prova, none are so divisive as the ones relating to food.
The Kagzar are obligate carnivores, and must consume meat for complete nutrition. Jasemi are vegetarians, and abstain from any meat that does not come from an insect source. Kagzaren biology differs from the Kagzar, allowing them to digest plant matter and remain healthy, but suffer from a reduced life span for it. Kotfisken are omnivorous, and will eat anything that provides a complete enough nutritional profile.
Kagzar, being carnivores, enjoy meat for every meal. Pufbulo are raised for their meat primarily, and though a Pufbulo is rather small for a meat animal, they transfer food to weight at an astonishingly fast ratio allowing for early slaughter. Pufbulo meat is the mainstay of every Kagzar tribe: dried into jerky, roasted over an open fire, boiled in a stew, or even eaten raw, the Kagzar have more ways to prepare Pufbulo than Bubba-Gump has for shrimp. Cherished above all cuts is the nose. A Pufbulo's nose is mild in flavor, exceedingly tender, and similar to fillet mignon of beef in quality. This cut is reserved for the elders of the tribe, or those carrying a child.
Pufbulo also provide milk, which the Kagzar drink straight or ferment into thick yogurts that are heavily spiced and eaten with dried meat. Cheese is a common wintertime treat, preserved in the cooler weather for when the hunt is poor.
Aside from Pufbulo, the Kagzar hunt for more exotic meats to consume. Vostruo meat is a delicacy for its rich and gamey flavor, and the stretchy tail-mouths make excellent broth for stews. Darmegon meat is poor, but the tail-poison is used as a condiment with a rich texture and sour flavor once the poison has been cooked out of it. But the most notable prey they hunt is also the strangest: the Jasemi.
Yes, Kagzar eat Jasemi, and the Jasemi have no problems with this. Thanks to Jasemi religious belief, they feel that giving their brief mortal lives up so a Kagzar can eat is a noble action and frequently give themselves willingly to Kagzar raiding parties. Jasemi flesh tastes, naturally, like chicken, and is best served roasted over an open flame until lightly charred.
Jasemi themselves are herbivores, and eat almost entirely domesticated fruit and vegetables. The Jasemi discovery of farming was the direct predecessor to the modern Jasemi village, and no village is incomplete without a farm dedicated to growing roots, berries, and greens. Jasemi are not fussy about their meals, and will eat any combination of food that is in season. Bread is the only cooked food that the Jasemi regularly consume, made from flour ground from grass seeds. The bread is flat and unleavened, and forms the base of most Jasemi meals; various fruits, nuts, and greens are placed into a large piece of bread, wrapped up, and eaten. Groups of especially isolated Jasemi do not even farm, instead harvesting fruits and nuts from deep inside the jungle by hand.
Though vegetarian, Jasemi are capable of digesting dairy and insect protein. Pufbulo yogurt and cheese make a very rare treat, and the Jasemi will sometimes trade with Kagzar tribes for dairy products in exchange for tools. Insect protein is a fundamental source of nutrition; Jasemi harvest small flying insects by the thousands to press into insect gruels that is spread upon flatbreads and eaten. Agagl are never eaten, even in times of famine, as the Jasemi feel they are too intelligent to humanely kill.
Kagzaren eat a similar diet to the Jasemi with farms of their own, but eschew all forms of animal based food. Thanks to hundreds of years of natural selection, the Kagzaren have evolved past the point of needing meat protein to survive, but their lifespans have shortened for it. Kagzaren are, technically, malnourished.
Some Kagzaren, seeking to perfectly imitate the Jasemi, still allow the consumption of Pufbulo dairy. Others, attempting to gain perfection in Luno's eyes, refuse anything but fruit that would fall naturally from a plant. These dietary restrictions vary greatly from tribe to tribe, depending on whatever agreement the priests of that tribe have come to about diet.
Kotfisken, on the other hand, are anything but picky about their diet. They are omnivorous and capable of digesting most anything that can be eaten. Food is given no special thought aside from being fuel for the body; Kotfisken meals are unspiced, unseasoned, and almost always uncooked. The Kotfisken enjoy the meat of their non-sentient cousins, the Kotfisk, consumed raw and sometimes still alive. Enormous farms of algae and seaweed provide a vegetable component, sustaining the entire pyramid-city on its rich kelpy goodness. Kotfisken even cannibalize their dead; they see it as irrational to waste such an excellent source of meat.
