Folate and pregnancy
Preventing neural tube defect
Recent research has shown that women who have a high level of the vitamin folate (folic acid) before they become pregnant are less likely to give birth to a baby with the abnormality known as neural tube defect.
The neural tube is that part of the developing fetus from which the skull, brain and spine develop. Defects in this system occur in about one in 500 babies. The most common defect is spina bifida, affecting the lower spine. Other defects include anencephaly, in which the brain does not form properly. Babies with these defects often die, while others have problems with walking and with bowel and bladder control.
Folate-rich foods
It has now been shown that a diet rich in folate, before and in early pregnancy, can prevent up to 70 per cent of these abnormalities.
Folate is found in most plant foods, especially green leafy vegetables, wholegrain breads, cereals and legumes (peas, beans and lentils). The vitamin is destroyed by cooking and prolonged storage, so it is best to eat fruit and vegetables that are fresh, raw or only cooked lightly.
Folic acid is also available in tablet form.
If you are planning to get pregnant, discuss your diet with your doctor. Be sure that you are getting plenty of folate to reduce the risk of this rare but serious problem for your baby.
