微量营养素缺乏是一种普遍现象，在发展中国家最为普遍。它与一系列疾病的发生有因果关系，影响着全世界数十亿人。通过生物技术提高作物产品中微量营养素的含量是一种很有前景的对抗全球微量营养素营养不良的技术。一些西方国家已经实施了食品的微量营养素强化，但发展中世界大部分地区的贫困农村人口仍然无法获得。此外，这种做法对人类健康，至少对某些维生素的负面影响的证据正在积累。作物生物强化——通过植物生物技术增强维生素和矿物质——是对抗微量营养素缺乏症的一种有希望的替代或补充。由于对维生素代谢以及植物对矿物质的吸收和再分配的了解不断增加，今天有可能提高作物植物中的微量营养素水平，为微量营养素摄入量不理想的人群提供可持续的解决方案。
Micronutrient deficiency is a widespread phenomenon, most prevalent in developing countries. Being causally linked to the occurrence of a range of diseases, it affects billions of people worldwide. Enhancing the content of micronutrients in crop products through biotechnology is a promising technique to fight micronutrient malnutrition worldwide. Micronutrient fortification of food products has been implemented in a number of Western countries, but remains inaccessible for poor rural populations in a major part of the developing world. Moreover, evidence of the negative impacts of this practice on human health, at least for some vitamins, is accumulating. Biofortification of crop plants-the enhancement of vitamins and minerals through plant biotechnology-is a promising alternative or complement in the battle against micronutrient deficiencies. Owing to a growing knowledge about vitamin metabolism, as well as mineral uptake and reallocation in plants, it is today possible to enhance micronutrient levels in crop plants, offering a sustainable solution to populations with a suboptimal micronutrient intake.
