Background The EAT-Lancet Commission drew on all available nutritional and environmental evidence to construct the first global benchmark diet capable of sustaining health and protecting the planet, but it did not assess dietary affordability. We used food price and household income data to estimate affordability of EAT-Lancet benchmark diets, as a first step to guiding interventions to improve diets around the world. Methods We obtained retail prices from 2011 for 744 foods in 159 countries, collected under the International Comparison Program. We used these data to identify the most affordable foods to meet EAT-Lancet targets. We compared total diet cost per day to each country's mean per capita household income, calculated the proportion of people for whom the most affordable EAT-Lancet diet exceeds total income, and also measured affordability relative to a least-cost diet that meets essential nutrient requirements. Findings The most affordable EAT-Lancet diets cost a global median of US$2•84 per day (IQR 2•41-3•16) in 2011, of which the largest share was the cost of fruits and vegetables (31•2%), followed by legumes and nuts (18•7%), meat, eggs, and fish (15•2%), and dairy (13•2%). This diet costs a small fraction of average incomes in high-income countries but is not affordable for the world's poor. We estimated that the cost of an EAT-Lancet diet exceeded household per capita income for at least 1•58 billion people. The EAT-Lancet diet is also more expensive than the minimum cost of nutrient adequacy, on average, by a mean factor of 1•60 (IQR 1•41-1•78). Interpretation Current diets differ greatly from EAT-Lancet targets. Improving diets is affordable in many countries but for many people would require some combination of higher income, nutritional assistance, and lower prices. Data and analysis for the cost of healthier foods are needed to inform both local interventions and systemic changes. Funding Bill & Melinda Gates Foundation.

Stunting affects 160 million pre-school children globally with adverse life-long consequences. While work within nutritional science suggests that stunting in early childhood is associated with low intakes of animal-sourced foods (ASFs), this topic has received little attention from economists. We attempt to redress this omission through an analysis of 130,432 children aged 6–23 months from 49 countries. We document distinctive patterns of ASF consumption among children in different regions. We find evidence of strong associations between stunting and a generic ASF consumption indicator, as well as dairy, meat/fish, and egg consumption indicators, and evidence that consuming multiple ASFs is more advantageous than any single ASF. We explore why ASF consumption is low but also so variable across countries. Non-tradable ASFs (fresh milk, eggs) are a very expensive source of calories in low-income countries and caloric prices of these foods are strongly associated with children’s consumption patterns. Other demand-side factors are also important, but the strong influence of prices implies an important role for agricultural policies—in production, marketing and trade—to improve the accessibility and affordability of ASFs in poorer countries.

International humanitarian organizations have expressed substantial concern about the potential for increases in food insecurity resulting from the COVID‐19 pandemic. We use a unique panel survey of a representative sample households in Addis Ababa to study both food security and food consumption during the pandemic. In contrast to some other countries in the region, Ethiopia never went into a full lockdown severely restricting movement. Despite subjective income measures suggesting a large proportion of households have been exposed to job loss or reduced incomes, we find that relative to a survey conducted in August and September of 2019, food consumption and household dietary diversity are largely unchanged or slightly increased by August 2020. We find some changes in the composition of food consumption, but they are not related to shocks found in previous phone surveys conducted with the same households. The results therefore suggest the types of subjective questions about income typically being asked in COVID‐19 phone surveys may not appropriately reflect the magnitude of such shocks. They also imply, at least indirectly, that in the aggregate food value chains have been resilient to the shock associated with the pandemic.

Objective: To revisit seasonality by assessing how household diets vary across agricultural seasons in rural and urban Ethiopia. The role of seasonality on the sources and intake of energy (per capita) and household dietary diversity score (HDDS) was analysed. Design: The use of nationally representative household-level data collected each month over one year to study the seasonal changes in the sources and intake of energy and HDDS. Setting: Eleven regions of Ethiopia, including rural and urban settings.
