'Gut flora is the term for micro-organisms that live in the gastrointestinal tract. There are 100 trillion of them compared to our 10 trillion cells. If the intestines were opened and spread out to expose their inner linings, they would cover a tennis court.

We have a symbiotic relationship with all these friendly bacteria. Not only do they deter invading pathogens and assist with digestion, they also signal other aspects of our immune system in other parts of our bodies. The colony of helpful bacteria is sometimes called our “forgotten organ.”'
