| Summary: | Background: Micronutrient deficiencies impact over two billion people globally, particularly in low- and middle-income countries, leading to severe health issues. Traditional interventions such as supplementation and dietary diversification face limitations, necessitating sustainable solutions like biofortification to enhance the nutritional content of staple crops.
Objective: This review aims to synthesize advancements in biofortification techniques, including agronomic, conventional breeding, and genetic engineering approaches, to address micronutrient deficiencies while ensuring crop yield stability and consumer acceptability.
Methods: A systematic analysis of peer-reviewed literature from 2000 to 2024 focused on biofortification strategies for key crops such as vitamin A cassava, iron pearl millet, and zinc wheat. Data were evaluated for nutritional efficacy, scalability, and socioeconomic impacts.
Results: Biofortified crops demonstrate significant efficacy: provitamin A maize improved serum retinol levels by 30% in deficient children, while iron-biofortified pearl millet increased hemoglobin concentrations by 15%. Agronomic techniques (e.g., foliar fertilization) and CRISPR-Cas9 gene editing emerged as scalable solutions, though challenges like GMO regulations and farmer adoption persist.
Conclusion: Bio fortification offers a cost-effective, sustainable strategy to combat malnutrition. Future success depends on interdisciplinary collaboration, policy harmonization, and community engagement to optimize crop nutrient profiles and ensure widespread adoption.
