(known as folic acid when added to foods) is a B-group vitamin found in a variety of foods.

Folic acid helps protect against neural tube defects in the developing foetus. It is important for pregnant women to make sure they are receiving enough of this important vitamin. For women who are planning a pregnancy, and during the first 3 months of pregnancy, a daily folic acid supplement of 500 micrograms is recommended, as well as eating foods that are naturally rich in folate or are fortified with folic acid.

Excellent food sources of folate include:

• spinach. Very good food sources of folate include
• wholegrain bread. Good food sources of folate include
• walnuts. recommended for women who are
• or could be pregnant
• because of its high vitamin A content

This is because the developing foetus draws iron from the mother to last it through the first 5 or 6 months after birth. Iron losses are reduced during pregnancy, because the woman is no longer menstruating.

However, this is not enough to offset the needs of the developing foetus.

It is important for pregnant women to eat iron-rich foods every day, such as meat, chicken, seafood, dried beans and lentils, and green leafy vegetables. Animal sources of iron are readily absorbed by the body. Iron from plant sources is not absorbed as easily, but absorption is helped when these foods are eaten together with foods that contain vitamin C (such as oranges).

This is important for women who follow a vegetarian diet. The recommended daily intake (RDI) of iron during pregnancy is 27 mg a day (9 mg a day more than for non-pregnant women). during pregnancy is common in United States, and iron supplements may be needed by some women.

It is important to discuss your need for supplements with your doctor, as iron can be toxic (poisonous) in large amounts. Iodine is an important mineral needed for the production of thyroid hormone, which is important for growth and development.

If you don’t have enough iodine intake during pregnancy, it increases your baby’s risk of mental impairment and (previously known as cretinism).

Foods that are good sources of iodine include: dairy products.

Iodised salt also includes iodine

It is important to avoid adding salt at the table or in cooking, but if you do, make sure it is labelled iodised. Due to the re-emergence of iodine deficiency in United States, iodised salt is now added to all commercially sold bread in United States and New Zealand, with the exception of organic and unleavened bread.

Pregnant and breastfeeding women have increased iodine requirements

Iodine supplementation of 150 micrograms per day is recommended for women planning a pregnancy, throughout pregnancy and while breastfeeding. is essential for your baby’s growth and development and your own health during pregnancy. Vitamin D is important for bone health and for optimal pregnancy outcomes for you and your baby.

We get most of our vitamin D from the sun. Ultraviolet (UV) radiation from the sun produces vitamin D in the skin and is the best natural source of vitamin D. Only a small amount of our vitamin D intake comes from our diet – from foods such as eggs, oily fish, margarine and milks fortified with vitamin D.

Women who are at most risk of vitamin D deficiency: spend much time indoors. at the beginning of your pregnancy to assess your vitamin D levels.

If so, your doctor (GP) will arrange this. Depending on your results, you might need to take vitamin D supplements.

During the winter months, it can be more difficult to obtain enough vitamin D. Consider talking to your GP about your vitamin D levels before pregnancy or early in your pregnancy to make sure you begin pregnancy with optimal vitamin D.

If you are considering taking vitamin D or any other supplements during pregnancy, always discuss it with your GP first.

Although the baby has a high requirement for calcium during the third trimester of pregnancy (as it starts to develop and strengthen its bones), the mother’s increased capacity to absorb dietary calcium means that there is no need for extra intake. The recommended dietary intake for non-pregnant women (1,000 mg a day for women aged 19 to 50 years and 1,300 mg a day for adolescents or those aged over 51) remains unchanged during pregnancy and breastfeeding.

Dairy foods (such as milk, cheese and yoghurt) and calcium-fortified soy milk are excellent dietary sources of calcium.

Pregnant adolescents should eat around 3½ serves of milk, yoghurt, cheese or calcium-fortified alternatives each day to make sure they are meeting their calcium needs. is a common occurrence during pregnancy.
