Zulu Native Fruits. Fruit grows plentifully in Zulu territories, and is eaten fresh as a part of daily meals. Some of the fruits have seeds that are used as nuts or for oil, including the marula and mobola plum. The mobola plum has seeds that are considered to be a substitute for almonds.he repeated use of the cooking pot is said to add special flavors to every meal cooked in them. Although many Zulu people eat farmed produce like pumpkins and tomatoes, they have a history of foraging native foods such as umfino (wild spinach), amadumbe, cassava and Jew's mallow.
