Breastfeeding means a healthy diet is important. Fluids, especially water, are also important for a good supply of breast milk. Breastfeeding uses a lot of energy and nutrients such protein, calcium, iron and vitamins. A strict diet to lose weight is not recommended while breastfeeding.
A healthy diet is always important, but it’s especially important if you are breastfeeding. Breastfeeding uses a lot of energy and nutrients. It is important that your diet supplies the nutrients you need during breastfeeding, such as protein, calcium, iron and vitamins. You need these nutrients for your own health and wellbeing. Try to eat regularly and include a wide variety of healthy foods.
How to get your daily nutrient requirements
Breastfeeding burns up a lot of energy (kilojoules). Some of the energy will come from the fat you laid down in pregnancy. However, most women will need to eat extra snacks to meet their energy needs. A steady weight loss back to your pre-pregnant weight should be the goal, rather than rapid weight loss. Use your appetite and weight to work out your energy needs.
Ideal snacks that provide nutrients and energy include:
- Sandwiches, bread and raisin toast
- Milk drinks
- Cereal with milk
- Nuts and seeds
- Cheese and biscuits
- Dip and vegetables.
Many women are very thirsty during breastfeeding, a sign that you need to drink plenty. Expect to drink up to two litres a day. All fluids count but water is the best source of fluid, so include a large share of your fluids as water.
It is important to include plenty of protein in your diet, including:
- Meat, fish and chicken
- Cheese and yoghurt
- Nuts and seeds
- Legumes – for example, lentils, baked beans and split peas.
You need around four serves of calcium-rich foods daily to protect your bone strength. Calcium is another major ingredient in breast milk. Good sources of calcium include:
- Dairy products such as milk, cheese and yoghurt (these are the best source of calcium)
- Soymilk fortified with calcium – look for a brand that includes around 120mg calcium per 100ml soymilk.
Pregnancy uses up your iron stores. During breastfeeding, you need to rebuild your iron stores with iron-rich foods, such as:
- Red meat, chicken and fish
- Legumes – for example, baked beans
- Nuts and dried fruit
- Wholegrain bread and cereals
- Green leafy vegetables.
Folate and vitamins
Breastfeeding also increases your need for:
- Folate – for example, leafy green vegetables such as spinach, broccoli, cabbage and brussel sprouts
- Vitamin C – for example, citrus fruits, berries, tropical fruit, tomatoes, capsicum and potatoes
- Vitamin A – for example, dark green and yellow vegetables such as broccoli, carrots and pumpkin.
Getting back to your usual weight
Although breastfeeding burns up a lot of energy (kilojoules), it can take several months to get back to your usual weight, so be a little patient. Some women do have a problem with extra weight. Tips for losing weight include:
- Grill, steam, bake or casserole lean meat, fish and poultry.
- Eat vegetables – at least five servings per day.
- Eat fruit – at least two servings per day.
- Choose low fat dairy products.
- Use butter and margarine sparingly.
- Avoid high fat foods, such as chips, rich desserts or greasy takeaways.
- Limit your intake of sugary foods, such as soft drinks, fruit juices, sweet biscuits, cakes, and lollies.
- Exercise – for example, push the pram around the block. Build up to 30 minutes daily.
- Enjoy healthy snacks to meet your energy needs (see above).
Foods to avoid
There is little evidence that certain foods upset babies or give them diarrhoea or colic.
Caffeine passes into breast milk, so large amounts of tea, coffee and cola drinks are best avoided. Drinking small amounts of drinks with caffeine (three or less drinks a day) should not be a problem.
A vegetarian diet can meet the nutritional needs of a breastfeeding mother as long as it includes a variety of foods, such as:
- Eggs, milk, cheese and yoghurt
- Wholegrain breads and cereals
- Fruit and vegetables.
Don’t go on a strict diet
Strict diets and skipping meals are not recommended because you could miss out on vital nutrients.
