Abstract
Biofortification was first proposed in the early 1990s as a low-cost, sustainable strategy to enhance the mineral and vitamin contents of staple food crops to address micronutrient malnutrition. Since then, the concept and remit of biofortification has burgeoned beyond staples and solutions for low- and middle-income economies. Here we discuss what biofortification has achieved in its original manifestation and the main factors limiting the ability of biofortified crops to improve micronutrient status. We highlight the case for biofortified crops with key micronutrients, such as provitamin D3/vitamin D3, vitamin B12 and iron, for recognition of new demographics of need. Finally, we examine where and how biofortification can be integrated into the global food system to help overcome hidden hunger, improve nutrition and achieve sustainable agriculture.
