The gut is the gateway to all disease. Besides helping with digestion of fatty acids, protein, and carbohydrates, its function goes way beyond. The gut is about immunity and preventing infection.
More than 80% of our immune system is in the gut as well as 70% of our lymphocytes. There is a gut-brain connection that is finally now being understood.
The gut is a large neuroendocrine system. It holds more than 100 million microbes. This is the reason everyone is talking about the microbiome. These different bacteria in the microbiome play very important roles in biological function. They help us fight dangerous organisms, keep the immune system in balance, and modulate autoimmune disease such as hashimoto's thyroiditis, multiple sclerosis, and lupus.
Why is this so important? The gut is the gateway to all disease. A clean gut means a healthy body free of all disease. Bacteria have been linked to gastrointestinal cancers, inflammatory bowel disease, and much more.
