The United Nations’ Sustainable Development Goal 2 focuses on efforts to “end hunger, achieve food security and improved nutrition, and promote sustainable agriculture,” (1) but progress has been insufficient to meet these goals by 2030. The cost of healthy, nutritious food is a major barrier to adequate nutrition, especially in low-income countries (1). To address malnutrition and food insecurity, national governments, with assistance from development partners and technical experts, must reform and strengthen agrifood systems to make low-cost, nutrient-dense foods affordable to all.
