We live in a bacterial world. Not only are the microscopic organisms all around us, they're found inside our bodies -- living and growing alongside us. Joining us to tell us all about the wonders of the microbiome is Dr. Liisa Veerus. It turns out some bacteria may be more important than we realise.

• A quick read on our ancestral microbiome
• A free, at-home gut test that could be a fun experiment for the entire family
• A list of foods to feed your microbiome during the upcoming holidays
