These were the findings of Canadian researchers who studied the population in Newfoundland, an area with historically high rates of neural tube defects (BMC Pregnancy and Childbirth 2004;4:20). They found that the rate of such defects was 78% lower after fortification. They conclude that fortifying food with folic acid at the …
