Improving iron, zinc and vitamin A nutrition through plant biotechnology.
Recent understanding of plant metabolism has made it possible to increase the iron, zinc and beta-carotene (provitamin A) content in staple foods by both conventional plant breeding and genetic engineering. Improving the micronutrient composition of plant foods may become a sustainable strategy to combat deficiencies in human populations, replacing or complementing other strategies such as food fortification or nutrient supplementation.
