Synbiotics: helping support your child’s gut health

Right now, there are trillions of microorganisms in your gut – and that’s a good thing. At every stage of life, these gut bacteria (also known as the microbiome) help us digest and metabolise food, fight bugs and are involved in processes that regulate our mood.1

For infants and toddlers, getting the right balance of gut bacteria can affect health status in later life.2 And that’s where the new science of synbiotics comes in.

What are synbiotics?

You might have heard about probiotics and prebiotics.

Probiotics are live microorganisms that add ‘good’ bacteria to your gut and can help aid digestion. Prebiotics feed the good bacteria in your gut.

Synbiotics, quite simply, are a combination of the two. The science of synbiotics helps us understand how getting the right mix of probiotics and prebiotics can ensure the right microorganisms survive and thrive in the gut.3

Synbiotics and kids

Right from birth, a baby’s gut is populated with microorganisms, and the nutrition they receive afterwards affects how this microbiome develops.

Breastfeeding delivers an ever-changing combination of prebiotics and probiotics that’s tailored to the baby’s needs.4 It passes on beneficial microorganisms delivering about 200 types of prebiotic that feed the ‘good bacteria’ in the baby’s gut.5

Once a child is eating solids, a balanced and healthy diet gives them a synbiotic mix of both prebiotics and probiotics. Fibre-rich foods which include many vegetables, cereals and fruit provide prebiotics, while fermented foods like yoghurt, sauerkraut and kombucha can contain probiotics.6

The benefits of the right synbiotic mix

For growing kids, getting the synbiotic mix right will help ensure optimum gut health- which in turn helps their overall health.

An unhealthy or unbalanced gut can increase the risk of gastrointestinal problems such as conspitation and diarrhoea, and increase the chance of developing allergies.7

On the other hand, a well-balanced gut microbiome can support your child’s developing immune system, and help with digestion of nutrients from a healthy well balanced diet so they can grow, play and thrive.8

Supporting choices for mums

Before you enter, please read this important statement:

If you are able, breastfeeding is best. It provides all the nutritional health benefits as Mother Nature intended. In readying for and during breastfeeding, it's important that mums eat a healthy, balanced diet.

If you're considering bottle feeding, seek professional medical advice first. Introducing bottle feeding either partially or exclusively, may reduce the supply of your own breast milk, which makes reversing the decision not to breast feed difficult. Also consider the social and financial implications, such as convenience and cost over time.

When using infant formula, always follow the instructions for use carefully, unnecessary or improper use may make your baby ill.
