Folate
Food fortification

Folic acid is added to grain products in more than 80 countries, either as required or voluntary fortification, and these fortified products make up a significant source of the population's folate intake. Fortification is controversial, with issues having been raised concerning individual liberty, as well as the theorized health concerns described in the Safety section. In the U.S., there is concern that the federal government mandates fortification but does not provide monitoring of potential undesirable effects of fortification. The Food Fortification Initiative lists all countries in the world that conduct fortification programs, and within each country, what nutrients are added to which foods. The most commonly mandatory fortified vitamin – in 62 countries – is folate; the most commonly fortified food is wheat flour.
