The Gut is far more than a filter. It is our wall of defense and acceptance between the outside world and everything we are exposed to. Specific programming that happens at our gut wall programs our immune system in a way that makes us able to resist pathogens from the outside world. If the gut defense is confused, our immune system is confused and the stage is set for allergies, auto-immune conditions and even certain cancers. Our gut determines our immune surveillance. Our gut is also responsible for making things like serotonin, a neurotransmitter that gives us sense of well-being and prevents depression. So much from heart disease to depression starts in the gut. By using markers such as Zonulin, Diamine Oxidase and Lipopolysaccharide we can see how healthy our gut is, how it is igniting our immune system and gain the upper hand on treatments that are best suited to calm our gut and sharpen our wall of defense!
