The Microbiome


The microbiome is a term used to describe all of the microbes, like bacteria and fungi, which live in the intestinal tract of all humans.


It's important to remember that not all microbes make us sick! Our microbiomes perform important tasks for us, such as digest our food, protect us from infections and help our immune systems develop.


We know certain factors help to shape our microbiome, including our diets, environment and exposure to things like antibiotics.
