Updating of the nutritional guidelines for the Polish population requires updates of the nutritional norms for children. We present the Polish Expert Group statement (2012) on intake of selected nutrients (protein, lipids, carbohydrates, vitamin D and E) essential in nutrition of children aged 1-3 years. For this purpose the Expert Group reviewed available scientific data: the recent guidelines, nutritional norms and recommendations, systematic reviews and expert opinions as well as original publications, in relation to the specific requirements of the Polish population.
