Cow's milk and sorghum (millet) are the staples of the Nuer diet. Maize (corn), okra and sesame are also cultivated. Milk is viewed as necessary for children; families temporarily without milk can usually get it, or a lactating cow, from a relative. In areas closer to rivers, fishing helps to bridge the hunger gap at the end of the dry season. The Nuer also eat the meat of their cows but not as much as you might think, slaughtering their cattle more for ritual and religious ceremony than for food. They are highly adapted to their environment. I run the risk of romanticizing the Nuer, but I have to say it: The Nuer are tough, resilient and highly resourceful. They would have to be, to survive for thousands of years in this harsh environment.
