importance of nutrition for breastfeeding mums

Every drop of breastmilk helps your baby

Breast milk gives your baby the best start. Breast milk contains water, energy (kilojoules/calories), protein, fat, carbohydrates, and minerals such as calcium. The first milk (2-4 days after birth) the body produces is called colostrum and is important for the baby’s immunity. Coming into the new world, they need protection. It is a formula high in protein and low in fat/sugar. This is followed by transitional milk and mature milk (10-15 days postpartum). To meet the demands of the mother, it is crucial that the mother consumes a variety of nutrients. Choosing nutrient-sense and nourishing foods is essential to support breast milk production.

Breastfeeding in the first 6 months can ensure your baby grows gradually and prevent obesity later if life. Breastfeeding may also reduce the risk of diseases later in life such as heart disease, diabetes and eating disorders. Breastfeeding can also create a bond due to skin-to-skin contact. As well as releasing oxytocin (happy hormone) and reducing stress levels for you and your baby.

supporting breastfeeding nutrition for breastfeeding mothers

Why is the mother’s nutrition so important during their breastfeeding journey?

Simply, it takes a lot of energy to make this liquid gold.

Lactation increases the mother’s nutrient needs, due to the loss of nutrients BUT also the process of making it. Some of the energy comes from the fat deposited during the third trimester of pregnancy. So, eating a balanced diet in accordance with the Australian Dietary Guidelines can ensure a healthy weight is maintained.

It is estimated that breastfeeding requires an additional 2,000-2,100 kJ/day (480-500 calories) per day. However, this calls on the addition of other nutrients such as vitamin D, vitamin A, vitamin E, vitamin C, B12, selenium and zinc. This is why ensuring that you are eating a variety of nutrient-dense, whole foods is important for your overall health and your baby’s.

Does this mean I eat more of the five food groups?


Vegetables, Legumes & Beans: 7 ½ serves.

Meat/Meat Alternatives: 2 ½ serves.

During pregnancy, iron stores are depleted and therefore an additional 0.5 serves is essential to replenish your levels. These are also important for Omega-3 to assist with brain development. Aim for oily fish such as salmon, mackerel, or tuna 2-3 times per week.

Let’s not forget Water…
