A “nduduagworagwo” is a traditional food of Akokwa people in Imo State, South eastern, Nigeria. Based on the recent linkage of natural foods to health, the anti-nutrients, amino acid quality and performance characteristics of “nduduagworagwo” traditional food was studied. Low levels of cyanogenic glycoside (0.09±0.03mg/100g), phytate (0.04±0.00 mg/100g), and oxalate (0.29±0.05 mg/100g) anti-nutrients were observed in the studied food. Anti-nutrient/nutrient interactions; oxalate/calcium (0.73), phytate/calcium (0.01), and phytate/iron (0.02) in “nduduagworagwo” were lower than their critical values. Essential and non-essential amino acids were also obtained in the food. The chemical scores for observed amino acids compared favourably with those of reference food materials and some other existing traditional foods. The performance characteristics in this study indicated that “nduduagworagwo” could be an intermediate protein food that can enhance the body with good digestibility (96.00± 2.87%) and biological (58.06± 1.04%) values. The present study has revealed the anti-nutrients, amino acid quality, and performance characteristic of “nduduagworagwo” traditional food.
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 B 2 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.
