Scaling Up Nutrition (SUN), is a movement founded on the principle that all people have a right to food and good nutrition. It involves the commitment of governments, civil society, the United Nations, donors, businesses and researchers to improve nutrition in a collective effort.

This framework document was created in 2010 in response to poor progress towards MDG 1. It outlines the social and economic consequences of undernutrition, the evidence and rationale for scaling up and recommends areas for prioritised action. The focus is on the evidence around the long-term and irreversible impact of undernutrition both on infant and child mortality and on longer term intellectual, physical and social development.

The framework draws heavily on the set of direct interventions outlined in the Lancet series, and a later review by the World Bank in 2009 which examined the feasibility and cost-effectiveness and identified a more selective package of 13 highly cost-effective interventions. These interventions, it is stated “could protect the nutrition of vulnerable individuals and communities and benefit millions of people if incorporated into food security, agriculture, social protection, health and education programmes.” Emphasis is also placed on the need for multi-sectoral cooperation, in recognition that direct, nutrition-specific interventions need to be complimented by a broader approach that includes integrating nutrition in related sectors.
