There are billions of people who are malnourished and facing food insecurity worldwide. By 2030, the United Nations has established a global goal to eradicate hunger, but we are still very far from achieving it. Food security has been challenged during the past ten years by climate change, population growth, and economic recession. To attain food and nutrition security, the food system must be transformed. Today, it is highly challenging to ensure food security so that the plant can produce its best products due to environmental stress factors that limit the production of important cereals. India has food security, but it lags behind in terms of nutritional security. The world's agriculture has advanced in many ways, such as biofortification, genetically modified crops, fortification, etc., but it has neglected the natural gift of nutria-cereals, which are resilient to climate change, highly tolerant of drought and other extreme weather conditions, rich in high nutrition and dietary fiber, and serve as good sources of protein, micronutrients, and phytochemicals. Additionally, it contains phytates, polyphenols, tannins, anthocyanins, phytosterols, and pinacosanols, all of which are significant contributors to ageing and metabolic illnesses. Due to their beneficial nutrient content, which includes carbohydrate, vitamins, proteins, and minerals, cereals are essential components of a nutritious and healthy diet. Millets are known as nutri-cereals because of their great nutritional value and potential to make a significant contribution to food and nutritional security. Additionally, they show very intriguing nutritional profiles that include macro and micronutrients as well as bioactive substances.
