Competing Interests

The authors have read the journal's policy and have the following conflicts: Petra Verhoef works at Unilever R&D in Vlaardingen, The Netherlands. Jane Durga works at Nestlé Research Center in Lausanne, Switzerland. The work at both food companies entails examining the health benefits of a variety of food ingredients, including folic acid. Unilever and Nestlé market food products, some of which are enriched with folic acid. This does not alter the author's adherence to all the PLoS ONE policies on sharing data and materials. All other authors declare that no competing interests exist.
