The number of micro-organisms living within the average human adult body are estimated to outnumber human cells ten to one. They are found anywhere in and on our bodies but are most concentrated in the digestive system, the gut flora. This gut flora has a dynamic and continuous effect on our immune system.

In order to understand how changes in normal bacterial populations affect us or are affected by disease we must consider lifestyle, nutrition, personal hygiene, exposure to stress, pollution and the environment we live in. Just as

the human mind allows a person to develop a concept of intellectual self, the immune system provides a concept of the biological self.

Exposure to bacteria and/or viruses and our reaction to these invaders or their transmutations will depend on the health of our microbial environment and our mental, emotional state. Microbes in our gut are connected to our well-being and are the biggest defenders of our health.
