Genetically modified (GM) crops have emerged as a significant innovation in modern agriculture, offering potential solutions to global challenges such as food insecurity, malnutrition, and environmental stress. By enabling precise genetic alterations, GM technology allows for the development of crops with enhanced traits including pest resistance, herbicide tolerance, improved nutritional quality, and resilience to adverse climatic conditions. These advancements have important implications for public health, particularly in improving food availability and addressing micronutrient deficiencies. This review paper examines the role of genetically modified crops in public health, focusing on their benefits, associated risks, and the policy debates that influence their adoption. The paper highlights the potential of GM crops to enhance food security, reduce pesticide exposure, and provide nutrient-enriched food options. At the same time, it critically evaluates concerns related to food safety, environmental sustainability, and socioeconomic equity. Issues such as allergenicity, gene flow, resistance development, and corporate control over agricultural inputs are discussed in detail. Furthermore, the paper explores the regulatory frameworks governing GM crops across different regions, emphasizing the importance of science-based risk assessment, transparency, and public engagement. Emerging technologies such as gene editing are also considered in the context of future agricultural innovation, genetically modified crops hold considerable promise for improving public health outcomes; however, their successful integration into food systems requires balanced policies, rigorous scientific evaluation, and inclusive governance to ensure safety, sustainability, and equitable access.
