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 paradox
Israeli Jews eat a diet which is richer in linoleic acid (the most readily available plant-based form of omega-6 fatty acid, found in many vegetable oils) than any other population on the planet. Average per capita consumption is approximately 30 grams a day (11 kilograms annually), compared to 25 grams daily for the average American in 1985.
