Little is known about the affordability of healthy foods and unhealthy foods in low- and middle-income countries, and how relative price may influence nutrition outcomes. This paper aims to quantify the link between price and dietary indicators and nutrition outcomes. Pulling from existing databases, it determines the relative caloric prices for foods across different categories, such as animal source foods and starchy staples, in 176 countries. The paper then compares food prices across countries to determine if there are associations between affordability and under- and overnutrition.
