ABSTRACT
People of poor are more exposed to risks of hidden hunger and malnutrition due to intake of carbohydrate-rich but deficient of micronutrient plant-based food. The development of high-yielding cultivars but by poor micronutrients further intensified the undernourishment. Several interventions have been used to increase dietary intake of nutrients such as dietary variation, clinical or pharmaceutical supplementation, industrial fortification (is the deliberately increasing the content of vitamins and essential macro- and micro-nutrients in a food), and crop biofortification (is a method by which the nutritional value of crops can be increased with the help of breeding and agronomic practices) are the major ways to get rid of these macro- and micro-nutrient malnutrition. Among them, crop biofortification is only one of the most appropriate, sustainable, and cost-effective ways to cater to the nutrient-deficient population of developing countries. Also, biofortification of staple crops has been proposed as a strategy to address micronutrient undernourishment, particularly with respect to insufficient intake of iron (Fe), zinc (Zn), vitamin A, and folate. Biofortified wheat, rice, maize, and other different crops biofortified with essential micronutrients as well as high levels of provitamin A, amino acids (such as tryptophan and lysine), 250protein and oils have great potential to benefit the world’s poor people, in terms of both economics and health.
