Adequate nutrition is a crucial component for child growth. Under- or malnutrition may not only affect present and future growth, but also a child’s ability to develop skills. In this publication, specialists in nutrition and growth present some of the best studies from peer-reviewed journals published between July 2016 and June 2017. Each paper is briefly summarized and supplemented with editorial comments which evaluate the clinical importance of each article and discuss its application. This ‘Yearbook’ is an important tool for practicing physicians, including pediatricians, subspecialists in pediatric gastroenterology, metabolism and nutrition, and endocrinology. Nutritionists and dieticians, as well as other health professionals involved in the care of children, will also find this to be a useful resource.
