This study assessed 11 candidate interventions developed through Delphi techniques to improve diets in India, Nigeria, and Ethiopia. A Markov simulation model incorporated time, individual-level, nutrition, and policy parameters to estimate health impacts and cost-effectiveness for reducing stunting, anaemia, diarrhea, and mortality in preschool children. At an assumed 80% coverage, interventions considered would potentially save between 0⋅16 and 3⋅20 years of life per child. The average cost-effectiveness ratio ranged from US$9 to US$2000 per life year saved. This approach, linking expert knowledge, known costs, and modelling, offers potential for estimating cost-effective investments for better informed policy choice where empirical evidence is limited.enNutritionHealthFood-based interventionsDietsCost-effectivenessArticle
