Wild African Fruits Pack More Protein Than Expected, Study Finds

Researchers at the University of Johannesburg have studied the nutritional content of 14 wild Southern African fruits. The findings reveal high levels of essential amino acids in many of these species. All of them contain lysine, which supports immune function and exceeds WHO daily recommendations. The white olive, or Halleria lucida, stands out for its protein (6.98 mg per 100 g) and carbohydrate content (36.98 mg per 100 g). It also contains high amounts of histidine, isoleucine, leucine, phenylalanine, and valine, surpassing WHO guidelines for daily intake. These amino acids play a key role in child development and adult health.

The jacket plum (Pappea capensis) is rich in lysine, providing far more than the adult daily requirement. It also delivers methionine, threonine, and a notable fat content of 5.11 g per 100 g portion. Another fruit, the Lowveld milkberry (Manilkara mochisia), leads in carbohydrate content, with 36.98 g per 100 g.

Among the studied fruits is the marula, a well-known species used in food, medicine, and cream liqueur production. While its nutritional details were not fully listed, it forms part of the broader research into these wild plants. The study highlights the potential of these fruits as valuable nutritional sources. However, further research is required to assess their commercial viability. The results suggest these wild species could contribute significantly to diets in the region.
