Genetically modified (GM) crops have become a prominent component of modern agricultural systems, offering potential solutions to food insecurity, malnutrition, and environmental stress. Through the application of genetic engineering techniques, crops can be enhanced for traits such as pest resistance, herbicide tolerance, improved nutritional composition, and resilience to climatic stressors. These innovations have significant implications for public health, particularly in addressing micronutrient deficiencies and improving food availability. However, the adoption of GM crops remains contentious due to concerns regarding food safety, environmental impacts, ethical considerations, and socioeconomic consequences. This review critically examines the role of genetically modified crops in shaping public health outcomes, with a balanced evaluation of their benefits, risks, and policy debates. The paper explores how GM crops can contribute to improved nutritional status, reduced pesticide exposure, and enhanced agricultural productivity. At the same time, it assesses potential risks, including allergenicity, unintended genetic effects, biodiversity loss, and the development of herbicide-resistant weeds. The review also addresses broader issues such as regulatory frameworks, public perception, intellectual property rights, and global disparities in technology access. By integrating evidence from agriculture, biotechnology, nutrition, and public health, this paper highlights the need for robust risk assessment, transparent governance, and science-based policymaking. It concludes that while GM crops hold considerable promise for advancing public health and food security, their successful integration into food systems requires careful management of risks, inclusive policy dialogue, and ongoing research to ensure safety, sustainability, and equitable benefits.
