This document discusses moving from ideas to action on nutrition data by adopting a data value chain approach. It outlines how global efforts since 2014 have prioritized indicators, created and collected new nutrition data through surveys, made data more accessible through databases, supported analysis tools, synthesized evidence for policies, and integrated data into decision-making. While progress has been made, it calls for continued investment across the entire data value chain from priority setting to use in order to achieve nutrition targets and monitor the SDGs. Adopting national data value chain plans can help translate evidence into action at country level.
