The UK government has responded to a campaign calling for an end to mandatory folic acid fortification of white flour, defending the policy as a crucial public health measure. The petition, created by Dr Clare Craig and signed by 20,000 people, argues that mass medication without consent is unethical. However, the Department for Health insists the policy prevents around 200 neural tube defect (NTD) pregnancies annually.
Petition Calls for End to Fortification
The petition on the Parliament website urges politicians to stop mandatory fortification immediately. It states: “We call on the Government to stop the fortification of flour with synthetic folic acid. Folic acid is a medicine not a food. We believe it is unethical to mass medicate the entire population without their knowledge or consent in the hope that a minority group of people might see a benefit.” The petition highlights that the NHS advises certain groups—such as people with cancer, a stent, or low vitamin B12 levels—to avoid folic acid due to potential harm, and that avoiding it is becoming harder as wholemeal and gluten-free products voluntarily add folic acid.
Government Response: Public Health, Not Medical Intervention
The Department for Health replied that the policy is a population-level public health measure, not a medical intervention. It applies to non-wholemeal wheat flour, reflecting existing fortification practices. The primary objective is to increase folic acid intake among women of childbearing age, reducing NTD risk. The policy is projected to prevent around 200 NTD-affected pregnancies annually—approximately 20% of UK cases. It also aims to improve folate status across the population, as folate plays a key role in forming healthy red blood cells and maintaining brain health.
Limited Success of Previous Campaigns
The government noted that previous efforts—public health campaigns promoting supplementation and voluntary fortification—have had limited success. Despite longstanding advice for women to take 400 micrograms of folic acid daily before conception and during early pregnancy, uptake remains suboptimal, especially among younger women and those from lower socio-economic backgrounds. Since almost half of UK pregnancies are unplanned, many women miss supplements during critical early weeks.
Labelling and Safety
All products containing folic acid must list it in ingredients. The Department for Health explained that the decision has a long history, recommended by the Scientific Advisory Committee on Nutrition (SACN) in 2006 after extensive evidence review. Subsequent reviews addressed concerns about adverse effects. The NHS provides guidance for those who need to avoid folic acid due to medical conditions or medication interactions. Foods like breakfast cereals and spreads have been voluntarily fortified for years without evidence of adverse health effects.
