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.

Contrary to the "old wives tale" that certain shellfish (i.e. prawns) raise cholesterol we now understand that the amount of saturated fat in the diet has a greater effect in raising blood cholesterol than the amount of cholesterol in the diet. So while dietary cholesterol is present in prawns, crabs and lobsters, as well as in squid and octopus, they contain very little saturated fat and for most people do not cause a rise in the level of cholesterol in the blood. Shellfish such as cockles, mussels, oysters, scallops and clams are very low in cholesterol, about half as much as chicken, and contain much less cholesterol than red meats.
