Dietary folate and the incidence and prevention of neural tube defects: a proposed triple intervention approach in Israel.

The efficacy of folic acid in the prevention of neural tube defects depends on whether it is administered to women during the period surrounding conception. Optimizing the compliance of women at this critical time is a public health challenge. We assess the need for formulation of public health policy in Israel aimed at enhancing folate intake by women, examine policy implementation strategies, and review policy options regarding the approaches to enhance folic acid intake.
