Ethiopian cuisine
Both Ethiopian Orthodox Christians and Muslims avoid eating pork or shellfish, for religious reasons. Pork is considered to be unclean in both Ethiopian Orthodox Christianity and Islam. Many Ethiopians would abstain from eating certain meats, and would mostly eat vegetarian and vegan foods.
Ortoiroid people
Ortoiroid peoples were hunter-gatherers. Shellfish remains have been found in these sites indicating that they constituted an important part of the Ortoiroid diet. They also ate turtles, crabs, and fish.
