The effects of food systems interventions on food security and nutrition outcomes in low- and middle-income countries

„ There is a strong focus on randomised trials. Mixed-methods approaches and those considering cost evidence are severely underrepresented in the literature. The devastating impacts of malnutrition and food insecurity are well documented. In lowand middleincome countries (L&MICs), constraints and complexities within food systems are significant drivers of these conditions. As a result, there has been a significant global focus on improving food systems to facilitate better food security and nutrition outcomes. The evidence base regarding the impact of interventions within food systems in achieving these aims is massive, but complicated and disorganised, making it difficult for donors, policymakers and practitioners to navigate.
