Connecting the dots
The body has no walls and each organ system interacts with every other and affects their function either in a positive or negative fashion.
The gut is a primary and central organ system which is truly the hub for the body as it is involved with digestion and nutrition vital for every organ in the body.
But in addition, its role in regulating metabolism, energy balance, hunger and satiety are not appreciated.
The gut is a primary detoxification center for environmental toxins food contaminants and drug metabolism. Without it, almost all the foods and drugs we ingest would be toxic. Independent of its role in digestion, the gut plays a vital role in immunity...that is protecting the body from harmful invaders both internalized and on the surface. As a regulator of the inflammatory response, it plays a role in chronic illnesses such as heart disease, arthritis and probably dementias such as alzheimer's.
There is a growing body of evidence that the gut with its connection to the brain via the nervous system, blood vessels ,and hormones plays a vital role in mood issues and behavioral conditions. Altering the gut's ecology, removing toxic substances, and enhancing its performance with dietary changes, probiotics and digestive enzymes can have profound effects on the gut and all the other organ systems.
