ABSTRACT
Chronic lifestyle diseases such as cardiovascular disease, type 2 diabetes, and obesity are increasing globally, now accounting for more than two-thirds of deaths worldwide. In this context, millets are regaining attention as nutrient-dense, climate-resilient grains from traditional diets. They are rich in protein, dietary fiber, essential vitamins, minerals, and bioactive compounds that contribute to improved metabolic health and overall well-being. This review compiles and synthesizes current scientific evidence on the nutritional composition, bioactive profile, and disease-modulating mechanisms of millets. It also explores the role of millets in gut microbiome modulation, particularly their prebiotic potential in stimulating the production of short-chain fatty acids (SCFAs) and enhancing gut barrier integrity. Furthermore, the review highlights innovative food applications, including the incorporation of millets into modern food products such as fortified flours, breakfast cereals, snack bars, and beverages. Millets have demonstrated the ability to blunt postprandial blood glucose spikes by up to 15%, reduce cholesterol levels by nearly 10%, and promote natural calorie regulation, thereby supporting weight management and metabolic balance. Their prebiotic fibers nourish beneficial gut bacteria, contributing to improved gut health and immune defense. By integrating traditional knowledge with modern nutritional science, millets emerge as promising functional foods for preventing and managing chronic lifestyle disorders. Promoting millet-based diets offers a sustainable and health-promoting approach to address the growing burden of non-communicable diseases.
