Nutrient adequacy for poor households in Africa would improve with higher income but not necessarily with lower food prices

Healthy diets are not affordable to all in Africa due to a combination of high food prices and low incomes. However, how African consumers might change demand patterns if prices or incomes were to change remains poorly understood. Using nationally representative household panel survey data from five sub-Saharan African countries, we model consumer preferences and examine how nutrient intake responds to changing food prices, total expenditures and other demand determinants. Here we find a stronger positive relationship between growth in poor consumers’ total expenditures and their nutrient intake adequacy than has been previously documented. We also find that poor consumers’ intake adequacy is especially sensitive to food staple prices in countries where one food staple dominates poor consumers’ diets. In countries with multiple food staples, no single staple’s price is a strong determinant of poor consumers’ dietary intake adequacy.
