Staple food crops, in particular cereal
grains, are poor sources of key mineral nutrients. As a
result, the world’s poorest people, generally those
subsisting on a monotonous cereal diet, are also those
most vulnerable to mineral deficiency diseases. Various
strategies have been proposed to deal with
micronutrient deficiencies including the provision of
mineral supplements, the fortification of processed
food, the biofortification of crop plants at source with
mineral-rich fertilizers and the implementation of
breeding programs and genetic engineering approaches
to generate mineral-rich varieties of staple crops. This
review provides a critical comparison of the strategies
that have been developed to address deficiencies in five
key mineral nutrients—iodine, iron, zinc, calcium and
selenium—and discusses the most recent advances in
genetic engineering to increase mineral levels and
bioavailability in our most important staple food crops.
