ABSTRACT

The consumption and encouragement of indigenous diets could help alleviate malnutrition and mitigate food insecurity in developing countries. In this regard, three Nigerian traditional diets: Akidi (Vigna unguiculata), Akara-Igboro (manihot esculenta), and Ofe-achara (Pennisetum purpureum soup) mixed with Mgbam (baked melon seed) and Garri (Cassva flakes) were evaluated for sensory characteristics, proximate composition, anti-nutrient composition, as well as vitamins, and mineral content using standard methods. Data from the sensory characteristics indicated that Ofeachara mixed with Mgbam and Garri (7.67 ± 0.89) was the most acceptable diet. The proximate analysis also revealed that Ofeachara mixed with Mgbam and Garri was highest in carbohydrate, (55.08 ± 4.66%), Ash (6.67 ± 2.89%) and moisture content (8.41 ± 0.89%) while Akidi was highest in protein (5.91 ± 0.05%) and crude fibre (12.31 ± 0.01%). The anti-nutritional analysis of the diets revealed that Akara-Igboro had the highest phytate (0.40 ± 0.01%), Alkaloid (50.00 ± 1.33%), oxalate (27.28 ± 0.88%) and Cyanogenic glycosides content (1.62 ± 0.12%) when compared to other diets. The vitamin content also showed that Akara-Igboro had the highest concentrations of vitamin B2 and C (21.67 ± 0.02g/100g and 17.01 ± 0.01g/100g) respectively. The highest level of calcium was found in Ofeachara mixed with Mgbam and Garri (0.08 ± 0.01mg/100g). This study revealed that these traditional diets are crucial sources of important nutrients. Increased consumption of these nutrient-rich diets will mitigate nutrition-related disorders.
