The UN has adopted a new indicator to measure minimum dietary diversity (MDD) as part of its framework to reach Sustainable Development Goal (SDG) 2 — end hunger, achieve food security, and improve nutrition and sustainable agriculture. Nutrition Insight speaks with the humanitarian organization’s agencies, FAO and UNICEF, co-custodians of the tool, to learn about tracking global progress in the fight against malnutrition by assessing the variety of foods consumed by women and children.
