In many areas of the world, inadequate amounts of micronutrients in the human diet have more devastating consequences than low energy intake. As examples, deficiencies in zinc, iodine, iron and vitamin A account for 11% of deaths of all pre-school aged children; also, sub-optimal intakes of vitamin C and folate present significant health threats in several developing countries, as well as in developed ones. Micronutrients are involved in all aspects of growth and physiology of the human body, even as early as during embryonic development. Micronutrient deficiencies can cause birth defects, permanent physical and mental impairment and increased risk of death by infectious diseases. As plant scientists, we are now facing ever more challenging and urgent goals with respect to the quality of our food supply. As important players in the global effort to improve crops, we should ask ourselves: how do we feed the world’s increasing population and how do we feed it better? In other words, we n
