Even though it can help in alleviating the burden of hidden hunger, only the leafy part is utilized whereas the plant has edible berries. This study sought to address the problem of underutilization by looking at the benefits that can be derived from the berries. Four varieties of the plant were harvested through four stages; green, colour break, ripe and at senescence. Chemical analyses of the berries were done to determine the content and changes in macro and micro-nutrients and the phytochemical content of the berries as they ripened. Analysis of Variance (ANOVA) was used to determine the significant difference between nutrient and phytochemical composition of the different S. nigrum varieties at different ripening stages. The results show that fibre, ash and protein increased at senescence while carbohydrates decreased. Magnesium was the most abundant mineral. As berries ripened, oxalates, total phenols, flavonoids and phytates decreased while Vitamin C, tannins and total carotenoids increased. Conclusively, the berries in this study have comparable nutritional value with other commonly consumed fruits and could, therefore, be incorporated into the family pot.
