Your Microbiome Behaves Like an Invisible Organ

We imagine the body as a single organism, but we carry a crowded ecosystem. The densest neighborhood is the gut. The microbiome can help break down fiber and produce certain molecules. It is also thought to communicate constantly with the immune system. When balance shifts, changes linked to some health conditions can appear. That is why diet, antibiotics, and lifestyle effects are studied. The microbiome expands the definition of self. Health can be the harmony of a community, not only one body.
