The microorganisms living inside your digestive tract depend on what you eat.
Diet is one of the major factors influencing the composition of the gut microbiome, alongside age, antibiotics, illness, stress and exercise.
Researchers now recognise that these microorganisms are involved in much more than digestion.
The gut communicates continuously with the brain through the gut-brain axis, and a landmark 2011 study demonstrated that changing the gut microbiome altered both behaviour and brain chemistry in mice.
While these findings cannot be directly translated to humans, they have encouraged scientists to further explore the relationship between diet, the microbiome and brain health.
One of the simplest ways to support beneficial gut bacteria is by consuming adequate prebiotic fibre.
Unlike probiotics, which introduce live microorganisms, prebiotics provide nourishment for the beneficial bacteria already living in the digestive tract.
Among the best researched prebiotic fibres is Partially Hydrolysed Guar Gum (PHGG), which has been widely studied for digestive health, bowel regularity and support of beneficial gut bacteria.

To support your daily fibre intake, PHGG powder provides a gentle, highly researched prebiotic fibre that fits easily into everyday routines.
