The incidence of neural tube defects in the U.S. has declined 19% following the fortification of enriched grain products, according to a recent study by the U.S. Centers for Disease Control and Prevention.

According to the C.D.C., the number of neural tube defects per 100,000 live births decreased to 30.5 after folic acid fortification, from 37.8 before fortification.
