Global Progress of Industrially Milled Cereal Grain Fortification

Globally 86 countries have legislation to mandate fortification of at least one industrially milled cereal grain. Of these, 85 countries mandate fortification of wheat flour alone or in combination with other grains. One country - Papua New Guinea - has a mandate only for rice fortification.

See this spreadsheet of countries with mandatory legislation for each grain.

For regional information:

Use the Global Fortification Data Exchange (GFDx) in English or in Spanish (en español). to see which nutrients are in country standards for grains as well as edible oil and salt. Use these directions:

  • On the right panel, select the food vehicle of interest and the nutrients of interest.
  • Below the GFDx map is a table with information used to populate the map.
  • Below the table, scroll over the Download button and click on CSV to download a file with the selected data.

Note: If a country has multiple foods that include the nutrient in the standard, the country will appear multiple times in the downloaded file.

We define mandatory as legislation that has the effect of requiring fortification with at least iron or folic acid. Most countries permit fortification. Voluntary means the country has a standard for fortification, but fortification is not mandatory.

We estimate that 30% of the world's industrially milled wheat flour, 30% of industrially milled maize flour, and 1% of industrially milled rice is fortified with at least iron or folic acid through these mandatory and voluntary efforts. See the 2019 Annual Report for an explanation of the calculation.
