When you are planning a pregnancy it is an ideal time to think more about your food choices. Is the food you are eating providing you with all the nutrients required during pregnancy? Eating a healthy diet (as described in the dietary guidelines) will help you to meet your nutritional requirements more easily.
In addition, a new study has found that a healthy diet in the year prior to getting pregnant is linked to a lower rate of birth defects. If you are planning to become pregnant, try to:
|What to do||What this means|
|Make sure you're getting enough folate (folic acid)|
|Make sure you are getting enough iodine|
The National Health & Medical Research Council (NHMRC) recommends that all women planning a pregnancy or who are pregnant or breastfeeding take a 150µg (microgram) iodine supplement each day.
|If taking multivitamins, check they are specifically for pregnancy or preconception|
Vitamin A (retinol) is harmful in large amounts in pregnancy, so if you are taking a multivitamin check that it does not contain retinol.
|Avoid eating fish with higher mercury levels|
Eat fish 2-3 times a week but limit fish with higher mercury levels e.g. shark (flake), ray, swordfish, barramundi, gemfish, orange roughy, long and southern blue fin tuna – to less than once per fortnight.
The best way to make sure you are getting enough nutrients is to have a healthy well-balanced diet rather than relying on vitamin supplements. For more information on a well-balanced diet visit the Nutrition Australia website or see our webpages on healthy living.
Women should not be dieting when they are pregnant. There are certain nutrition needs that must be met during pregnancy and very strict dieting puts that at risk.
Calcium is one of the essential nutrients necessary for healthy bone development. Not only is calcium important to bones, it is also important for the function of various organs within the body and a certain amount of calcium circulates within the blood. If blood calcium levels fall, the body will compensate for this by drawing calcium out of bones and putting it into the blood. Calcium is also excreted by the body daily.
This means it is important to have an adequate daily intake of calcium through your diet, so your bone mineral strength is not compromised. The best sources of calcium are milk, yoghurt and cheese but other foods also provide calcium.
In pregnancy, the increased calcium requirement (to provide for skeletal growth in the foetus) is met through increased absorption in the mother's gastrointestinal system.
Women who breastfeed also have higher requirements for calcium, which is provided mainly from the mother's skeleton.
Normal pregnancy and breastfeeding is associated with a certain amount of bone mineral loss, which generally recovers 6-12 months after delivery and/or breastfeeding.
Due to adaptation made by the body to obtain more calcium during pregnancy and breastfeeding, the calcium requirements are the same as for non-pregnant women. The calcium requirements for pregnant and lactating women are:
|Age (years)||Recommended daily intake of calcium|
During pregnancy the body requires a greater amount of iron due to the gradually increasing blood volume of the mother and the formation of the baby's blood. The best sources of iron are red meat, chicken and fish but iron is also found in many other foods. It is important to include adequate amounts of iron in your diet throughout pregnancy to prevent anaemia and ensure the baby has adequate iron stores when born.
Folate (also called folic acid) is a B vitamin needed for healthy growing, in particular for the nervous system. Folate helps:
Adequate intake of folate during pregnancy and breastfeeding is crucial, and requires a high quality diet. However, large surveys show women who are pregnant and breastfeeding often have a poor intake of folate through their diet.
All women who are pregnant or planning a pregnancy are recommended to take a folate supplement.
In Australia, up to 42% of women aged 24-80 years have or have had urinary incontinence or 'leakage' . Many women also experience bowel incontinence.
It is also possible to have pelvic floor muscles that are working too hard. In this case, women may experience pelvic pain and discomfort during intercourse.
The pelvic floor is a very important group of muscles and one that is not talked about or exercised enough. Pelvic floor muscles are the layer of muscles spanning underneath the pelvis.
Along with abdominal and back muscles, the pelvic floor helps to stabilise and support the spine, digestive system, pelvic and reproductive organs (including bladder, bowel and uterus) and plays an important role in preventing incontinence and supporting the pelvic organs. The pelvic floor is also important for sexual function in women, with voluntary contractions contributing to sexual sensation and arousal.
One of the risk factors for pelvic floor weakening is pregnancy and childbirth particularly:

Sometimes fibroids cause problems in pregnancy or they interfere with labour and delivery. The number and position of the fibroids will determine if there is a problem. Fibroids can increase the risk of:
