The guts defense system

Updated: Feb 12, 2020


if you read my last 2 articles under gut health you now know exactly what happens from the time you consume food until you poop it out.


One of the reasons why we are not all bedridden by infection is because of our gut defense system. The body has 2 main lines of defense, the intestinal wall, which acts as a physical barrier to foreign invaders and the immune system.


The body has 2 main lines of defense, the intestinal wall, which acts as a physical barrier to foreign invaders and the immune system.


The wall of our intestine is made up of a barrier of cells that are effectively secured by tight junctions. The intestinal wall serves a dual purpose, it allows nutrients in and keeps pathogens out, which are the bad guys.


However these junctions can become weak, or loose allowing unwanted bad guys to sneak accross the wall.


You might have heard of leaky gut! Well this is how a leaky gut happens.


However the body is pretty clever and even if this happens our immune system is primed and ready to hit hard, triggering a cascade of events within and outside our gut to shut down any nasty bad guys.


The immune system is very complex, it involves a high level of network cells, tissues and organs that work as team to fight off the bad guys. The 70% of immune tissue that lies within our gut has a very important job, because our digestive tract is the most popular gateway in the body.


It's a pretty hard job, a 24 hour patrol team, sifting through millions of foreign cells each day.


So what happens when things go wrong? The team is good but sometimes they get overwhelmed and s**t hits the fan, the immune tolerance is compromised and this is where conditions such as allergies and autoimmune diseases arise.
