Implementing Maize Flour Fortification

Wheat flour and maize flour are milled with similar processes. See the Flour Millers Toolkit for information on implementing and monitoring fortification at mills.

Maize is the third most commonly consumed cereal grain in the world, after wheat and rice. We estimate that 65% of the world's industrially milled maize is fortified (see page 10 of our 2017 Annual Report).

In Africa, less than 30% of the industrially milled maize is fortified. See this strategy document for scaling up maize flour fortification in Africa from 2017 to 2026.

The World Health Organization offers guidelines for fortifying maize flour "as part of a comprehensive food-based strategy for combating micronutrient deficiencies." Micronutrients are vitamins and minerals that people need in small amounts. These nutrients can easily be provided through fortified foods.

On the map below, the green counties have mandatory fortification for industrially milled maize flour. The dark gray countries are places where at least 75 grams of maize flour is available per person per day for human consumption, but fortification is not mandatory. For specific country information, see the country profiles.
