Nutritional intake of Solanum nigrum Linn. leaves fortified with peanut paste consumed at breakfast in rural zones in Côte d’Ivoire

Abstract

In Côte d’Ivoire, Solanum nigrum Linn. leaves are consumed at breakfast in rural zones most of the time fortified with peanut paste. Thus, in this study, this meal was evaluated by appropriate methods for its nutrients content in order to determine if it can cover the needs of the morning of famers. The results showed that the macronutrients contents were 2.27 g, 1.7 and 0.23 g per 100 g of fresh leaves respectively for proteins, carbohydrates and lipids, with an energy value of 17.95 kcal. That represents 2.99% of the energetic intake a low-activity adult man needs at breakfast which is 600 kcal. However, after cooking and fortification of these leaves with peanut paste, this energy value increased to reach the value of 600.69 kcal. This covers well the energy value that a low-activity adult man needs at breakfast. These leaves content also minerals (Ca, Fe, Mg, Mn, K, Na, Zn and Cu), fibers and vitamin A. This nutrients intake was significantly improved after the fortification with peanut paste. Thus, as these leaves fortified with peanut paste are consumed mainly by farmers before starting their daily activities, we can conclude that this meal covers their nutritional needs of the morning.
