Foxtail millet is increasingly gaining global attention as a climate-smart and nutritionally superior cereal crop with substantial potential to contribute toward sustainable agriculture, food security, and human health. In the context of rapid climate change, declining agricultural resources, and the rising prevalence of lifestyle-related disorders, foxtail millet offers a promising alternative to major staple cereals due to its exceptional adaptability and rich nutritional profile. This review critically examines the agronomic importance, nutritional composition, functional attributes, therapeutic potential, and future prospects of foxtail millet in modern food systems. Foxtail millet demonstrates remarkable tolerance to drought, heat stress, and low soil fertility, while requiring minimal agricultural inputs, making it highly suitable for cultivation in arid, semi-arid, and climate-vulnerable regions. The crop is recognized for its sustainability, resilience, and ability to support agricultural productivity under adverse environmental conditions. Nutritionally, foxtail millet is an excellent source of dietary fiber, quality proteins, essential amino acids, vitamins, minerals, and bioactive phytochemicals such as polyphenols, flavonoids, and antioxidants. These compounds impart significant functional and health-promoting properties, positioning foxtail millet as an important component of functional foods and nutraceutical formulations. The low glycemic index and gluten-free nature of foxtail millet make it particularly beneficial in the prevention and management of metabolic and chronic diseases, including diabetes mellitus, obesity, cardiovascular disorders, and gastrointestinal complications. Scientific evidence further highlights its role in improving lipid metabolism, enhancing gut microbiota, reducing oxidative stress, and promoting overall metabolic health. In addition, advancements in food processing technologies, biofortification approaches, and molecular breeding strategies have opened new avenues for enhancing the yield, nutritional quality, consumer acceptability, and stress tolerance of foxtail millet. Despite its immense potential, the large-scale utilization of foxtail millet remains constrained by limited consumer awareness, insufficient value chain development, poor market integration, and inadequate policy support. Therefore, strategic efforts involving research institutions, governmental agencies, food industries, and farming communities are essential to promote its cultivation, processing, and commercialization. In conclusion, foxtail millet represents a highly promising climate-resilient crop with multifaceted benefits for sustainable agriculture, nutritional security, and public health. Its integration into future food systems could play a vital role in addressing global challenges associated with climate change, malnutrition, and non-communicable diseases. Continued research, technological innovation, and policy-driven interventions will be crucial for unlocking the full potential of this ancient yet future-ready cereal crop.
