About GFDx

The Global Fortification Data Exchange (GFDx) provides unparalleled access to critical data on food fortification, along with tools to aid in analysis and visualization. GFDx empowers governments, donors, implementing agencies, researchers, the private sector and other members of the global fortification community to develop data-driven policies and programs to reach populations affected by vitamin and mineral deficiencies.

The GFDx website aggregates and visualizes data on five commonly fortified foods—maize flour, oil, rice, salt, and wheat flour—to inform the planning, resourcing, implementation, and evaluation of fortification programs. It includes indicators on food fortification legislation from 1940 to present, legislation scope, fortification standards, availability of regulatory monitoring protocols, food availability and intake, proportion of foods industrially processed, fortification quality and compliance, population coverage, alignment of national fortification standards with WHO guidelines, potential nutrient intake from fortification, and health status indicators before and after fortification.

The site enables users to:

  • Generate custom maps, charts, tables, and plots to analyze trends and derive insights.
  • Download data for offline analysis, for those who want to dig deeper into the fortification data.
  • Explore continuously updated data, ensuring access to the latest fortification information.

GFDx makes fortification data open, discoverable, and actionable

By consolidating available data for all five foods, GFDx allows national decision-makers to more holistically evaluate their fortification initiatives, identify gaps, and make informed comparisons across nutrients, foods, countries, and regions.

With GFDx data, decision makers can answer critical questions like:

  • How many and which countries require the mandatory fortification of maize flour, oil, rice, salt, or wheat flour?
  • In countries with legislation standards, what nutrients are required to be included in fortified foods?
  • How much maize flour, oil, rice, salt, or wheat flour is available or consumed in a given country?
  • What proportion of maize flour, oil, rice, salt, or wheat flour is industrially processed and hence able to be fortified?
  • How much of the food consumed in a given country is fortified at levels that meet the country’s standards?
  • What proportion of a country’s population is consuming fortified maize flour, oil, rice, salt, or wheat flour?
