Pregnant woman and women who are trying to get pregnant are routinely prescribed prenatal vitamins containing at least 1,000 milligrams of folic acid as a way to improve the health of the unborn child. In the mid-1990s, the Food and Drug Administration (FDA) took the effort one step further, requiring that folic acid be added to breads, cereals, flours, corn meals, pastas, rice and other grain products. Researchers say that move likely contributed to the 26 percent drop in neural tube defects, according to the U.S. Centers for Disease Control and Prevention. Now they say folic acid also may be tied into the six percent drop in heart defects each year after folic acid was added to grain supplies, researchers say.

While congenital heart defects are rare, such news is encouraging. “If you can reduce such a significant abnormality by doing something as simple as a public health intervention by increasing folic acid in the grain supply and encouraging individuals to take folic acid supplementation, it’s a win-win situation,” said Dr. Diane M. Ashton, deputy medical director of the March of Dimes.

Besides consuming a folic acid supplement or consuming foods high in folic acid, another step a woman can take to improve her chances of having a healthy baby is to discuss with her doctors any medications she is taking. Some drugs, such as SSRI antidepressants like Paxil, have been linked to a an increased risk of overall birth defects, and specifically heart defects.
