The interactive map displays countries that have official documentation and/or a food standard that provides guidance or regulations for fortification (“voluntary fortification”) or legal documentation that has the effect of mandating fortification of a food with one or more vitamins or minerals (“mandatory fortification”), or countries that have written standards for the nutrients added in fortification (“fortification standards”). The color of each country indicates the number of food vehicles for which some form of legal documentation exists, also detailed in the table below the map. Country classifications for region are from the United Nations and income status classification from the World Bank.
