Exploding global population, rapid urbanization, salinization of soils, decreasing arable land availability, groundwater resources, and dynamic climatic conditions pose impending damage to our food security by reducing the grain quality and quantity. This issue is further compounded in arid and semi-arid regions due to the shortage of irrigation water and erratic rainfalls. Millets are gluten (a family of proteins)-free and cultivated all over the globe for human consumption, fuel, feed, and fodder. They provide nutritional security for the under- and malnourished. With the deployment of strategies like foliar spray, traditional/marker-assisted breeding, identification of candidate genes for the translocation of important minerals, and genome-editing technologies, it is now tenable to biofortify important millets. Since the bioavailability of iron and zinc has been proven in human trials, the challenge is to make such grains accessible. This review encompasses nutritional benefits, progress made, challenges being encountered, and prospects of enriching millet crops with essential minerals.

全球人口爆炸式增长、快速城市化、土壤盐碱化、可耕地减少、地下水资源和动态气候条件通过降低粮食质量和数量对我们的粮食安全造成迫在眉睫的损害。由于灌溉水短缺和降雨不稳定，这一问题在干旱和半干旱地区更加复杂。小米不含麸质（蛋白质家族），并在全球范围内种植，用于人类消费、燃料、饲料和饲料。它们为营养不足和营养不良的人提供营养保障。随着叶面喷施、传统/标记辅助育种、重要矿物质易位候选基因的识别和基因组编辑技术等策略的部署，现在对重要的小米进行生物强化是可行的。由于铁和锌的生物利用度已在人体试验中得到证实，因此挑战在于使此类谷物易于获取。这篇综述包括营养益处、取得的进展、遇到的挑战以及用必需矿物质丰富小米作物的前景。
