Hidden hunger is a public health problem worldwide, currently not only speaks about the deficit of a macronutrient and its consequences, it is increasingly emphasized the importance of an adequate intake of vitamins and minerals that not consumed in their quantities correct it is difficult to detect its affectation in the organism since it is not detectable to the naked eye, for example growth retardation, night blindness and a very little developed immune system. Due to this, biofortification emerged, which is a process to increase the nutritional value or content of micronutrients in foods from the crop, through different techniques such as agronomic or genetic biofortification. Although there are currently many vitamins and minerals that report low consumption, the World Health Organization and institutions such as HarvestPlus that support this strategy, focus on the main deficits: vitamin A, iron and zinc, applying biofortification in basket crops basic such as rice, wheat, beans, corn, among others. Therefore, this review presents key elements such as the requirements of the minerals and vitamins mentioned the advantages and disadvantages of each technique and the crops where it is mostly applied, to understand biofortification as a strategy to be easily included in the diet.
