Eating well before and during pregnancy plays a vital role in your baby’s growth and development. The physical and hormonal demands of pregnancy create extra demands for certain nutrients to support your own body’s needs and the growing needs of your baby.
***Key Points***
The benefits of healthy eating for you and your baby
- Iodine: brain development
- Folic acid: blood formation and cell building
- Vitamin D: calcium and absorption and bone health
- Iron: brain development and energy levels
- Calcium: bone development
- Vitamin B12: nerve and brain development
- Protein: blood supply and tissue growth
Make sure your diet is varied and includes a variety of these foods
- Meat, fish*, poultry, eggs, tofu, beans, and nuts
- Eat a range of different coloured fruit and vegetables – make yourself a rainbow plate.
- Bread, cereal, rice, noodles – swap white varieties for wholegrain and eat fibre rich foods such as oats, beans lentils, grains, and seeds.
- Milk, cheese, yoghurt, or dairy alternatives
- Drink plenty of water
You are not required to eat more (the need to eat for 2 is a myth) but try to eat a greater variety of foods
***Key Points***
***Fish***
There is good evidence that eating fish regularly during pregnancy (low-mercury fish) is also beneficial for you and your growing baby. Fish is important for developing your baby’s brain and nervous tissue. One to three serves of fish per week is recommended.
There are certain types of large fish that should be limited because they contain high levels of mercury. Shark, Marlin and Swordfish should not be eaten more than once every two weeks and Sea perch (Orange Roughy) and Catfish no more than once per week.
Shark (flake), broadbill, marlin and swordfish shouldn’t be eaten more than once per fortnight and orange roughy (sea perch) and catfish, more than once per week. Other fish are safe to eat.

***Vegetarians***
If you are vegetarian, you can replace meat and animal products with lentils, beans, tofu, eggs and soy milk. If you do not eat animal foods or products, you should talk to your health professional about a supplement. They may suggest you take a vitamin B12 supplement, as this vitamin is needed for the baby’s brain development.

***Folate***
Folate (or folic acid) is especially important two months before you fall pregnant and the first trimester (three months) of pregnancy. A good intake of folate reduces the risks of your baby being born with spinal conditions such as spina bifida
As well as eating foods rich in folate, a daily supplement containing 500mcg (0.5mg) of folic acid is recommended.
If there is a family history of cleft lip, spinal problems or you are taking an anti-epilepsy medication, this dose may need to be greater. Women who are diabetic or have a high BMI may also require an increased dose.
Please discuss this with your Midwife, GP, or Obstetrician.
Food’s high in folate includes
- Green leafy vegetables e.g., spinach, salad greens or broccoli
- Cereals or breads with fortified folate

***Iron***
Iron is needed to make red blood cells that carry oxygen around the body. Your body makes more blood when you are pregnant which means you require more iron.
If you iron levels are low n pregnancy this can make you feel tired, lethargic and have poor concentration. If your levels are very low this can affect your baby’s growth or of your baby being born early.
Your iron levels are most important in the third trimester of pregnancy. This is when your baby increases their own iron stores ready for life after birth.
Iron from meat sources (haem iron) is taken up by the body more efficiently than iron from plant foods (non-haem iron)
Meat is the best source of haem iron. The redder the meat the better source of iron. Red meat like beef and lamb has higher amounts than pork, chicken and fish.
The best sources of plant iron include wholegrain and iron fortified breads and cereals, legumes such as kidney beans, baked beans and chickpeas, tofu and green leafy vegetables. Eggs are also a good source of iron and nuts and dried fruits.
5 Quick nutritional tips for improving your iron intake
- Include at least two serves of meat, chicken, fish, legumes or nuts every day
- eat plenty of dark green leafy vegetables
- Combine iron-rich foods with these high in Vitamin C, which helps with iron absorption e.g., citrus fruits, tomatoes or capsicum
- Limit foods that interfere with iron absorption e.g., coffee tea or more than 2 teaspoons of unprocessed bran
Most pregnant women require 27mg iron per day. (over 45mg can be harmful).
If your iron is low, talk to your Midwife, GP, or Obstetrician about taking iron supplements. Remember, your pregnancy multivitamin may also contain some iron.

***Iodine***
Iodine is a nutrient that is important for your baby’s brain development. To ensure adequate iodine you can
- eat fish one to three times a week, (limit high mercury types as above)
- use iodised salt
- take a multivitamin for pregnancy that contains iodine.
***Iodine***
***Calcium***
Calcium helps form healthy bones. Dairy foods such as yoghurt, cheese and milk are the easiest sources. Other sources include cabbage, bok choy, silverbeet and almonds.
***Calcium***
***Vitamin D***
Vitamin D helps the body use and absorb calcium. And works together to build your baby’s bones. Sunlight helps your body make its own Vitamin D. Vitamin D is contained in margarine, egg yokes, milk and oily fish, however only in small amounts.
If you have dark skin, are indoors a lot or cover your skin in the sunlight you may be advised to take a Vitamin D supplement.
***Vitamin D***
***Omega 3***
Omega 3 fatty acids are used for your baby’s healthy brain development, nerve development and eye development. Oily fish is the best source, vegetarians can source Omega 3’s from walnuts, linseeds/flaxseeds or chia seeds and soy beans.
