From its inception SIGHT AND LIFE has focused its attention on vitamin A, but the international community is increasingly realizing that vitamin A deficiency does not occur on its own. In the late 1970s, Dr Mejia showed that vitamin A nutrition improved or influenced the iron status in rats1 and children2, and many workers have confirmed these findings since then. While the mechanism by which vitamin A improves iron status still eludes us, it is now widely accepted that there is a metabolic interaction between these and other micronutrients, which means that nutrition workers can no longer justify the luxury of just addressing one nutrient in their work. For this reason SIGHT AND LIFE has also decided to adjust to developments and the literature digest will now cover all micronutrients accordingly.
