What you should know about this indicator

  • A nutrient adequate diet meets all essential nutrient requirements, with sufficient diversity and quantity of locally available foods to stay within the upper and lower bounds for total protein, fats, and carbohydrates as well as essential vitamins and minerals required to avoid nutrient deficiencies or toxicity.
  • The data is measured in international-$ at 2021 prices - this adjusts for inflation and for differences in the cost of living between countries.
Daily cost of a nutrient adequate diet
Cost of the least expensive locally-available foods for nutrient adequacy for a representative person within upper and lower bounds for 23 essential macro- and micronutrients plus energy balance at 2,330 kcal/day. This data is adjusted for inflation and for differences in the cost of living between countries.

Sources and processing

This data is based on the following sources

Food Prices for Nutrition provides indicators on the cost and affordability of healthy diets 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 provides 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.

Version 3.0, estimated in July 2024, uses the 2021 global food retail price data from the International Comparison Program (ICP) and updates the methodology of calculating the affordability indicators, including indicators measuring the ratio between diet costs and international food poverty lines and indicators measuring the share and volume of the population unable to afford each diet, and they are based on the latest Poverty and Inequality Platform (PIP) data expressed in 2017 purchasing power parity dollars (PPP).

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 2022 standard (the fiscal year of 2024 of the World Bank).
