Iron and Folic Acid in Pregnancy

Ensuring you get enough nutrients during pregnancy is essential for both you and your growing baby. Iron and folic acid are two of the key nutrients you need, but how much should you be getting and what role do they play?

Iron is required to help the red blood cells transport oxygen around the body. During pregnancy, there's an extra demand for iron and other vitamins, which are needed for women, the unborn baby and the placenta. Many women find their levels of iron depleting during this time - which can cause anaemia.

Anaemia is especially common in women carrying twins, in those having pregnancies close together, in vegetarians, if you've had a loss of blood due to piles or stomach ulcers and if you haven't got enough folic acid in your diet. Anaemia can make you feel really tired, look pale, experience dizziness, breathlessness and palpitations. In severe cases, it can cause chest pain and headaches.

During pregnancy, your levels of iron should be checked at regular intervals. If it's found to be particularly low, you may be prescribed an iron supplement. However, you can boost your iron levels through eating iron-rich foods.

Foods rich in iron include:

• Lean red meat, such as pork, beef or lamb
• Eggs
• Dark poultry
• Sardines
• Cashew nuts
• Wholemeal bread
• Iron-fortified cereals
• Lentils
• Chick peas
• Baked beans
• Leafy green vegetables
• Dried fruit
• Baked potatoes
• Sunflower seeds

It's worth bearing in mind that the body doesn't absorb iron from non-meat sources quite as easily as it does from meat. However, you can help absorption by combining iron-rich foods with food or drinks rich in vitamin C, so as having a glass or orange juice with your meal. Both tea and coffee also reduce the absorption of iron, so it's better to drink these at least half an hour before you eat or two hours afterwards.

Folic Acid

Folic acid is one of the most important nutrients to have during the first trimester of pregnancy and before conception, as women deficient in folic acid have a greater risk of having a baby with a neural tube defect such as spina bifida.

Ideally, folic acid supplements should be taken from the time you're trying to conceive (if it's a planned pregnancy) to until the end of week 12 of your pregnancy. The recommended daily supplement dose is 400mcg, but women who've had a history of neural tube defects are usually prescribed a dose of 5mg. In addition to taking folic acid supplements, you should try and eat as much as you can each day, by eating plenty of foods rich in folic acid.

Good folic acid foods to eat include:

• Green leafy vegetables
• Citrus and kiwi fruit
• Peas
• Beans
• Cauliflower
• Fortified breakfast cereals
• Fortified bread
• Other fortified foods

It's useful to note that folic acid is lost when food is cooked, so it's advisable to only boil vegetables for a short period of time or steam them, to retain as many nutrients as possible.
