Facing the global nutrition challenges, the World Health Organization (WHO) teamed up with the United Nations Institute for Training and Research (UNITAR) to design, under the guidance of the Department of Nutrition for Health and Development (NHD), a Nutrition Knowledge Hub. By building the technical and functional capacities of all relevant staff at WHO through e-learning courses and key nutrition-related training and knowledge materials, the Nutrition Knowledge Hub aims to contribute to the acceleration and increase of the nutrition impact at the country level. The Nutrition Knowledge Hub also offers free and open courses to reach a larger public and raise awareness on the malnutrition problem and WHO’s response.
