Add nutrients to food, says UN

The brainpower of nations has diminished due to a shortage of the right vitamins, and slipping nutrients into food is the solution says a United Nations survey. The UN backs a range of artificially-fortified foods: soy sauce laced with zinc, "super salt" spiked with iron, and cooking oil fortified with vitamin A.

Deficiencies in these vitamins are having alarming effects in developing countries, even ones where people have enough to eat. A lack of iron lowers children's IQs by an average five to seven points, the report said today.
