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.
Shellfish
Inter-tidal herbivorous shellfish such as mussels and clams can help people reach a healthy balance of omega-3 and omega-6 fats in their diets, instead of the current Western diets. For this reason, the eating of shellfish is often encouraged by dietitians.
Shellfish are also a rich source of the amino acid taurine.
