th awareness campaign no more than about 50 per cent of women took folic acid supplements before pregnancy. Voluntary fortification with folic acid can improve a population’s folate status, but most voluntary programs do not reach all the population.
Mandatory fortification provides a population safety net. The level of fortification proposed is generally low but could prevent about a quarter of pregnancies with spina bifida and ancephaly. Women still need to be encouraged to take folic acid supplements to achieve a higher level of prevention.
The suggestion that folic acid could cause negative side effects is unwarranted in my opinion. Hypothetical links between folic acid and cancer have been raised but do not bear scrutiny. As I shared during a presentation with the Food Standards Agency in Uppsala, Sweden, in January 2009, the possibility of harm is small and remote and insufficient to stop fortification.
Some may argue that even a remote and hypothetical risk is too great to take when the public’s heath is at stake. But denying a benefit is causing harm; there is no doubt that failure to fortify will cause harm. Typically wheat flour is centrally produced in large mills, which means government regulatory agencies are easily able to monitor compliance. Most modern mills are already equipped to handle fortification, and if the country requires flour fortification, the ongoing cost of buying folic acid for fortification is shared equally by everyone in the industry.
Most importantly, mandatory fortification means that women who need folic acid the most will receive an adequate amount of this essential nutrient without having to change their behavior. We should not accept the needless burden of disability from birth defects such as spina bifida when a proven method for reducing their incidence is available.”

I would like to wholeheartedly support Sir Nicholas Wald regarding his stance on mandatory fortification of folic acid.
As a consultant with over a decade of experience in advocating and implementing fortification of staple foods (wheat, maize/corn, vegetable oils, sugar and rice) in ECSA with a range of vitamins and minerals (A, B complex, Folic acid, iron and zinc) I can assure your readers that voluntary fortification, whilst laudable, is fraught with difficulties.
Major producers often use the addition of micronutrients as a marketing tool - and it can be argued that this is a valid and effective tool - but all too often it leaves the consumer unaware of the beneftits of that intervention and few producers have the necessary background information that will enable them to set the fortification levels at a point which will have the desired health impact. Frequently levels are set too low to have any significant impact.
In South Africa we have had mandatory fortification of wheat flour and maize meal since 2003 as part of an intergrated nutrition intervention which includes activities such as improving sanitation etc (don't feed the worms, feed the children) and are already seeing a significant decrease in incidents of NTD for example.
This success has been due to the commitment of the milling industry to the programme and whilst we have had our fair share of problems in monitoring and enforcement, due to lack of capacity with inspectors and focussing more on health safety issues i.e. the recent cholera outbreak, we have had a high degree of compliance.
It has also been interesting to note that throughout ECSA industry has usually required fortification to mandatory (arguing it keeps a level playing field) as opposed to voluntary fortification in which they could make some marketing mileage. Further, the fact that the fortification is mandatory, industry can be assured that Government gets involved in the essential components of any fortification programme - those of educating the consumer regarding the benefits of the interventi
