A comparative analysis using a forest resource Opuntia ficus-indica L. (prickly pear) and Pyrus communis (common pear) a commercial fruit: Implications on nutrition and food systems sustainability

Malnutrition and food insecurity persist in rural communities, where limited access to nutrient-rich foods exacerbates health challenges. Indigenous fruits like Opuntia ficus-indica L. (prickly pear) and Pyrus communis (common commercial pear) provide unique nutritional benefits, yet their potential synergy remains unexplored. This study analysed nutrient profiles of juices made from these fruits individually and in a hybrid formulation. Prickly pear juice (A1) demonstrated the highest Calcium (Ca) (46.43 mg/100 g) and Magnesium (Mg) (31.04 mg/100 g) concentrations, while common pear juice (A2) was a superior source of Potassium (K) (56.72 mg/100 g). The hybrid juice (A3) showed enhanced nutrient density, particularly for potassium (105.94 mg/100 g) and Vitamin C (VITC) (138.88 mg/kg), contributing up to above 100 % of the Estimated Average Requirement (EAR) for women. Nutrient contribution to DRIs was statistically significant (p < 0.005) for Ca, Mg, K and VITC for A1-A3 juice concentrations. The hybrid juice also displayed the highest composite Nutrient Density Index (NDI) (0.7480 mg/kcal), supporting its potential as a nutrient-dense beverage to combat micronutrient deficiencies. Integrating these fruits into rural diets can enhance food security, promote agroforestry, and improve dietary diversity. Policy recommendations include incentivizing indigenous fruit cultivation and incorporating hybrid products into nutrition programs to address malnutrition and promote sustainable food systems. • Prickly pear provides high calcium, magnesium, and antioxidants for arid rural diets. • Nutrient analysis supports prickly pear's inclusion as nutrient-dense forest fruit. • Nutrient Density Index (0.7480 mg/kcal) was observed for the hybrid juice. • Integration of indigenous and commercial fruits enhances food security and biodiversity. • Hybrid juice of prickly pear and common pear boosts nutrition and complements food systems.
