THE evidence that compulsory fortification of flour with folic acid helps prevent birth defects such as spina bifida is so compelling that it is difficult to understand the UK Government’s reluctance hitherto to implement the measure. It is already in place in 80 countries around the world.

Analysis of their experience has shown not only that adding folic acid can cut the risk of neural tube defects substantially but that concerns about side-effects have not been borne out. In the light of that, it is commendable that the Scottish and Welsh governments have written to Westminster Health Secretary, Jeremy Hunt, urging action on the matter so that a uniform approach can be adopted across the UK. The move is backed by the Food Standards Agency and the British Medical Association, which earlier this year reminded the UK Government of its stated aim to promote good pre-conception health ensuring every child got the best possible start in life.

The Government’s actual strategy, by contrast, appears to lie in persuading pregnant mothers to take supplements. But this ignores the fact that many pregnancies are unplanned, resulting in mothers taking supplements too late.

Many people are instinctively hesitant about mandatory food additives but, when it concerns the lives of children, and where the weight of evidence is clear, such measures will find support. We urge Mr Hunt to act accordingly.
