The Nuer are one of the largest ethnic groups in South Sudan, primarily residing in the Nile River Valley. The Nuer are a cattle-raising people, whose everyday lives revolve around their cattle. They have various terms related to cattle, so they can distinguish between hundreds of types of cows, based on color, markings, and shape of horns. They prefer to be called by the names of the cattle they raise. The commonest daily foods for the Nuer are dairy products, especially milk for the young and soured milk, like yogurt, for adults. And wild fruits and nuts are favorite snacks for the Nuer. The Nuer also have a culture of counting only older members of the family. They believe that counting the number of children one has could result in misfortune and prefer to report fewer children than they have.
