Benefits and Limitations of Non-Transgenic Micronutrient Biofortification Approaches

Abstract

Increasing the amount of micronutrients in diets across the world is crucial to improving world health. Numerous methods can accomplish this such as the biofortification of food through biotechnology, conventional breeding, and agronomic approaches. Of these, biofortification methods, conventional breeding, and agronomic approaches are currently globally accepted and, therefore, should be the primary focus of research efforts. This review synthesizes the current literature regarding the state of biofortified foods through conventional breeding and agronomic approaches for crops. Additionally, the benefits and limitations for all described approaches are discussed, allowing us to identify key areas of research that are still required to increase the efficacy of these methods. The information provided here should provide a basal knowledge for global efforts that are combating micronutrient deficiencies.
