Lindsay Rodriguez said to help prevent birth defects, women should take action while the baby is still in the womb. Not enough folic acid means babies could wind up with brain or spinal deformities.
March of Dimes is pushing women to take pre-natal vitamins. Rodriguez said eating healthy might not be enough, because the food that's high in folic acid might not be a top choice.
"Foods like beans, liver, spinach, broccoli. So people might think they're eating healthy, but those healthy foods might not be the right ones. So if you're not getting these foods in your diet, chances are you're not getting the 400 micrograms of folic acid needed each day," Rodriguez said.
Rodriguez says since so many pregnancies are unplanned, women should take vitamins even if they are'nt planning to have a baby.
