Synbiotics and the Gut Microbiota

The gut microbiota refers to the collection of trillions of bacteria, fungi, viruses and other microscopic organisms that reside in our gut. The gut microbiota plays an important role in immune system development in early life, helping to defend against infections, allergies and other immune-related conditions in later life.

Cow’s milk allergy (CMA) affects 2-3% of infants. Babies with CMA typically have an unbalanced gut microbiota (‘gut dysbiosis’) in comparison to non-allergic, breastfed infants. 

Breastmilk is the best source of nutrition for all babies including babies with CMA. Breastmilk contains friendly bacteria (probiotics) and components that act as ‘food’ for the friendly bacteria, e.g., fibres and lactose (prebiotics). The combination of probiotic bacteria and prebiotic components in breastmilk, together known as ‘synbiotics’, are important to promote a healthy gut microbiota and therefore support the developing immune system in breastfed babies.

Always consult your doctor if you suspect your baby has cow’s milk allergy or any other food allergy.
