Fortifying flour with folic acid to cut birth defects may lead to a range of health problems, warn scientists.
The move was approved earlier this year by the Food Standards Agency as a way to reduce defects such as spina bifida.
However, an Institute of Food Research team has shown the liver could easily become saturated by folic acid.
Writing in the British Journal of Nutrition, they warn this could lead to unmetabolised folic acid entering the blood, which could damage health. The latest study follows a letter to the Food Standards Agency from Sir Liam Donaldson, the Chief Medical Officer of England, requesting further expert consideration of two recent studies linking folic acid to bowel cancer before the government gives the final go-ahead for mandatory fortification.
