This study examines the relationship between children's diet diversity and household agricultural production diversity in Ethiopia using a large survey dataset. The study finds a strong causal relationship between what households produce and children's diets, rejecting the idea that consumption and production decisions are separable. However, this relationship does not hold for households with good access to markets. The study concludes that agricultural interventions should aim to increase productivity, market integration, and nutrition knowledge to improve children's diets rather than simply encouraging more diverse household production.
