1. The whole digestive tract is coated with a bacterial layer dominated by essential or beneficial bacteria, much like a thick layer of turf on the surface of the gut epithelium, providing a natural barrier against invaders, undigested food, toxins and parasites. And just like soil unprotected by turf becomes eroded, the gut wall suffers if the protective bacterial turf gets damaged.

2. Apart from acting as physical barriers, the bacterial layer dominated by essential bacteria (good bacteria) work against invasive pathogenic micro-organisms by producing antibiotic, anti-fungal, anti-viral substances that dissolve membranes of viruses and bacteria; they engage the immune system to respond appropriately to invaders.

3. In addition to producing organic acids, the essential bacterial layer reduces pH near the wall of the gut to 4.0-5.0, making a very uncomfortable acidic environment for growth and activity of pathogenic “bad” microbes which require more alkaline surroundings.

 

4. The essential gut flora (good bacteria) has the good ability to neutralize toxic substances and chelate heavy metals and other poisons. The cell walls of beneficial bacteria absorb many carcinogenic substances, making them inactive. They also suppress hyperplastic processes in the gut, which is the basis of all cancer formation.
