Summary The reduction of phytic acid content in grains by genetic manipulation is a novel approach to increase mineral absorption from food based diets. Low phytic acid corn ( Zea mays ), rice ( Oryza sativa ), barley ( Hordeum vulgare ) and soybean ( Gycine max ) genotypes have been generated and mineral absorption has been evaluated. Genetically modified low phytic acid plants could be a novel contribution to the reduction of micronutrient malnutrition and animal waste phosphorus. Nevertheless, additional research needs to be done to understand the molecular biology and genetics of phytic acid accumulation during seed development, the negative and positive roles of dietary phytic acid in human health and the feasibility and effectiveness of the sustainable implementation of this approach at the community level.
