Millets are a class of small-seeded grains belonging to the grass family, Poaceae. These are some of the first grains that people have ever grown. They have now become obscure, despite once being a vital part of the diets of Indian populations. Millets are excellent choices for eradicating nutritional deficiencies and hidden hunger in the global population. Their exceptional nutritional profile makes it simple to use them as a treatment for the many health problems and lifestyle illnesses that are plaguing people in this century. All of these species of annual grass are grown for both grain and fodder, and they are all members of the C4 family of plants. Millets are known for their climate resilience, which includes their adaptability to a wide range of ecological conditions, low susceptibility to environmental stresses, reduced irrigation needs, enhanced growth and productivity in low-nutrient input conditions, and decreased dependency on synthetic fertilizers. Millets have traveled a long way from ancient grains to reach their current designation as nutricereals. To lead a healthy life, these crops should not be overlooked and should be made a part of our daily diet.
