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.
Israeli cuisine
Although not all Jews in Israel keep kosher, the tradition of "kashrut" strongly influences the availability of certain foods and their preparation in homes, public institutions and many restaurants, including the separation of milk and meat and avoiding the use of non-kosher foods, especially pork and shellfish. During Passover, bread and other leavened foods are prohibited to observant Jews and matza and leaven-free foods are substituted.
