The human body is an open system, where all manner of microbes can flow in and out of – making it is virtually impossible to keep them out completely. For this reason, one of the best ways to prevent colds and flu from developing is to maintain a robust immune system. This can be done by ensuring that the internal environment within the body is both clean and inhospitable to the various infectious pathogens that may be lurking, thereby preventing them from taking root and proliferating. In terms of human physiology, the digestive system is actually considered to be outside of the body. The entire gut is a barrier between the body’s interior and the outside world, keeping out that which does not belong. Luckily, 80% of the immune system is actually located within the digestive system.
