Food Prices for Nutrition (FPN) provides indicators on the cost and affordability of a healthy diet (CoAHD) in each country, showing the population’s physical and economic access to sufficient quantities of locally available items for an active and healthy life. It also hosts indicators on the cost and affordability of an energy-sufficient diet and of a nutrient-adequate diet. These indicators are explained in detail in the Food Prices for Nutrition DataHub at: https://www.worldbank.org/foodpricesfornutrition.
The database version Food Prices for Nutrition 4.0, estimated in July 2025, relies on the 2021 global retail food price data from the International Comparison Program (ICP) and the latest 2021 PPP conversion factors to assess the diet cost indicators. For the non ICP benchmark years, it estimates the diet costs based on the latest food and general CPI data from FAOSTAT. Comparing to previous versions (see FPN Database Archives), it also reflects the most updated income distribution data for India and others from the World Bank’s Poverty and Inequality Platform (PIP). For the first time, the cost and affordability of a healthy diet and related indicators are estimated up to one year preceding the report year and diet cost indicators are both reported in PPP dollars and local currency units. Version 4.0 also updates the method of converting current year to constant year PPPs based on national CPIs instead of the US inflations. Estimates for the prevalence and number of people unable to afford a healthy diet were imputed for countries with missing information based on their regional and global aggregates. Countries' income classifications at the aggregate reporting level follow the calendar year of 2023 standard (the fiscal year of 2025 of the World Bank). The Cost and Affordability of a Healthy Diet indicators reported in the United Nations' State of Food Security and Nutrition in the World 2025 correspond to those in version 4.0.
The most recently updated database version, Food Prices for Nutrition 4.1, builds on version 4.0 and introduces two additional contextual indicators: GDP per capita, PPP (current international dollars), and GNI per capita, PPP (current international dollars), both sourced from the World Bank’s World Development Indicators (WDI) database. These indicators are included to facilitate comparisons between diet cost and affordability indicators and countries’ income levels.
