We have a pretty fixed view of what makes up the human body – cells, blood, tissues, bone and so on. But, did you know that inside your gut you carry around a whopping 2kg of microbes, which consists of over 1,000 different species of bacteria that outnumber our cells 10 to one? Most of us are aware that these bacteria play a hugely important role in the digestion process (breaking down food, absorbing nutrients etc), but science is increasingly viewing the microbiome as a new, unexplored and possibly intelligent organ in its own right.
Scientists are now asking, “What’s the connection between the health of our microbiome and our overall health? What role does the microbiome play in mood, depression, diabetes, autoimmune disease, inflammation, food allergies and cancer?”
