Modification of diet by means of genetic engineering methods shuld be an effective way to overcome problems derived from micronutrient deficiency. Here, we review the current status of knowledge of the micronutrient contents in native foods and matters of concern for the genetic engineering of their nutritional contents, and summarize the results of experiments in the development of high iron crops by ferritin gene transformation. This means that by increasing the storage capacity of iron in plants the potential activities of the iron uptake related mechanism can be induced and thereby create high iron content crops. Finally, we also discuss the possibility of storing more iron in ferritin and the expanded application of ferritin to further breeding other than iron storage.
