Malnutrition is a hidden killer of children. It is the underlying cause of 2.3 million child deaths every year. Globally it has also left 170 million children stunted globally, impairing their mental and physical development, and undermining their future potential. Despite making signiﬁcant progress towards reaching most of the Millennium Development Goals (MDGs), malnutrition is a problem that has been neglected. In some countries, malnutrition is actually getting worse.
