Pregnancy diet: Focus on these essential nutrients

Folate and folic acid — Prevent birth defects

Folate is a B vitamin that helps prevent neural tube defects, serious abnormalities of the brain and spinal cord. The synthetic form of folate found in supplements and fortified foods is known as folic acid. Folic acid supplementation has been shown to decrease the risk of premature birth.

How much you need: 400 to 1,000 micrograms a day of folate or folic acid before conception and throughout pregnancy

Good sources: Fortified cereals are great sources of folic acid. Leafy green vegetables, citrus fruits, and dried beans and peas are good sources of naturally occurring folate.

Food Serving size Folate or folic acid content
Source: USDA National Nutrient Database for Standard Reference, Release 28
Cereal 3/4 cup (15 to 60 g) ready-to-eat cereal 100 to 700 mcg — choose a cereal that's 50 to 100 percent fortified

In addition to making healthy food choices, taking a daily prenatal vitamin — ideally starting three months before conception — can help ensure you're getting enough of this essential nutrient. All women who might become pregnant should take a daily vitamin supplement containing folic acid.
