gut health and immune system

How Gut Health Affects Immune System

How gut health affects immune system?  Well, humans have 100 trillion microbial cells in our gut!  That is 10 times the number of human cells, so we are more bacteria than human.  Since our bacteria genome is 150 times larger than human ones, it’s not surprising that bacteria affect our weight, digestion, mood, concentration, memory, etc.  Let’s take a closer look.

Our Gut Health & Immune System

Good bacteria are vital to protect us from bad bacteria.  In addition, our immune system defends the body from unwanted pathogens.  Since most of our bacteria reside in the gut, 70-80% of our immune system joins the gut bacteria in a symbolic relationship to protect the body.  Other factors such as diet, environment, and lifestyle also play a role.

Associations between Gut Health & Immune System

Studies show that a decrease in good bacteria results in an overpopulation of bad bacteria.  Conversely, if we eat well and nourish our body, then good bacteria overpopulate the gut.  This results in more energy, better mood, better sleep, less pain, and the body working in alignment.

So when then does gut health affect the immune system and miscommunication happens?  It can be a variety of circumstances such as poor diet, antibiotics, surgery, heavy metals, chemotherapy, etc.  These factors lower our gut flora and therefore, lower our immune system.  The opposite is true if we increase our prebiotic foods through vegetables and legumes and decrease processed foods.  Subsequently, we increase our biodiversity which helps our gut flora.  It is all truly connected:  brain, body, food, and spirit.

The actions are simple but not easy because we have built some bad habits that are difficult to break.  These should not come as a surprise, but it’s about making it a consistent lifestyle.  How does one do that without all-or-nothing mentality and dieting?  Focus on these aspects and get the support to keep you on track:
