The Best Folic Acid Foods and the Benefits For Pregnant Women

There are plenty of folic acid foods that will help a pregnant woman reap folic acid benefits but the risks of prenatal deficiency may make a supplement the safest best.

Doctors regularly recommend folic acid to pregnant women. That’s because it’s crucial for fetal development. In fact, health professionals recommend folic acid be taken regularly beginning up to a year prior to conception. Many would-be parents treat this as minor dietary diversion, plucking a bit more asparagus out of the produce section. But can you just eat folic acid foods and forget about the supplements? Maybe not.

Why is Folic Acid Important?

Folic acid benefits neural tube formation in the first few weeks of fetal development. Very serious neural tube defects (NTDs) like spina bifida and anencephaly can occur if things don’t go well during that period.

“Folic acid does seem to be quite important in the development of the nervous system,” says Dr. Mary Jane Minkin, Clinical Professor of Obstetrics and Gynecology at Yale University. “It has been shown for many years that supplementation with folic acid before conception and continuing for the first few weeks of pregnancy significantly lowers the chances of babies being born with neural tube defects.”

Research shows that the risk of NTDs can decrease by up to 50 percent when women take the daily recommended 400 mcg of folic acid for pregnancy. For women who’ve already had a child with an NTD, that risk can decrease up to 70-percent. Those women, Minkin says, should load up on folic acid to the tune of 4 mg a day.

How Should Women Get Folic Acid for Pregnancy?

One of the best ways to score folic acid is through a daily supplement like a prenatal vitamin. It can be difficult to consume enough of it through food to hit the 400 mcg target that offers the real benefits.

“Unfortunately, it is hard to take in that much folic acid without a supplemental vitamin form,” Minkin says. “Many cereal products are fortified with folic acid, but again, most women do need a pill for folic acid supplementation to get the right amount.”

That said, you should still keep your eyes out for folic acid foods when you’re hitting the grocery store. Many breakfast cereals do include plenty of folic acid, but grains and flours can also be fortified with up to 100 percent (or more) of the daily value (DV).

To find if your grocery items include the levels of folic acid a pregnant partner needs, check out the nutrition label. Folic acid can also be listed as “folate.” The percentage to the right is the percentage of DV contained in a serving. “Folate” and folic acid are essentially the same in the benefits they provide pregnant women, the difference being that folic acid is synthetic, and folate is found naturally in certain foods. Although they are metabolized slightly differently, they offer the same prenatal benefits.

How to Make Sure Your Partner Gets 400 mcg of Folic Acid Daily

  • Supplement her diet with over-the-counter B9. Whether she’s taking swallowing tablets or capsules, using drops, or chewing gummies, make sure she’s getting at least the 400 mcg DV.
  • Shop for foods that are fortified with folic acid. Leafy greens, such as spinach salads, lentils, asparagus, and broccoli are all good sources. Citrus fruit and avocado are quite high too. Remember to track quantities, though, and make sure that the foods you choose contain enough to reduce those risks.
  • Consider your family history of NTD’s. If she has had a baby with an NTD before, research shows that a big increase in her folic acid intake is probably beneficial.
  • Always follow her doctor’s orders. As with everything during pregnancy, make sure that you follow the nutritional, dietary, and supplemental advice of her primary care physician and her OBGYN.

Are There Risks for Taking Too Much Folic Acid?

A study published early in 2016 suggests that “very high” levels of folate in women (far more than what is recommended) at delivery could double the risk of the child developing an autism spectrum disorder. That risk was doubled even further when high levels of B12 were also present. “Most experts agree that if a mother has a history of having had a baby with a previous neural tube defect that she actually take 4 mg a day of folic acid before she conceives again,” Minkin says. “So I don’t think that a higher dose should be problematic.” All of this supplementation should, of course, be under the guidance of a physician to make sure the quantities are sufficient and safe.

Minkin says that there may be additional benefits to consuming plenty of folic acid during pregnancy, too.

“There is emerging data on many other fronts that other problems may be reduced by folic acid supplementation,” Minkin says. “A few studies have shown a decreased autism risk; some studies have suggested a decrease in heart defects as well.”

The jury is still out about whether too much folic acid could be bad for men. So maybe it might be wise to put your daily multi on pause for the next nine months if your primary health-care person agrees.
