The Mind Gut Connection – Chris James

‘The state of your guts affects how you feel in your mind.’

To understand the Mind Gut Connection, you firstly have to understand the roles of the gut in the body.

The multiple functions of the gut interact with each other and with the food you eat to regulate your nutrition, metabolism, mental function, weight, energy and your susceptibility to illness.

• Your gut has its own nervous system, the enteric nervous system (ENS), which has as many nerve cells as your spinal column and has constant contact with your brain. This has a direct impact on your mood and mental function.
• Your gut is also home to about 100 trillion microbes and lives in a symbiotic relationship with favourable bacteria, yeast and fungi, viruses and an occasional worm. This is called the ‘microbiome’.
• Over two-thirds of your body’s immune system is found in the lining of the small intestine. Thus your gut is the largest immune barrier to the outside world.
• The gut is also an organ of detoxification. Much of this responsibility rests with the liver, but the intestinal lining cells are themselves rich in detoxifying enzymes.

The ENS has a number of key functions. It:

• Controls the immune system in the gut
• Coordinates the release of hormones as food arrives
• Helps to open up the gut to circulation after you eat, which help absorption of nutrients
• Choreographs and coordinates the contraction of the muscle cells that line the intestines to keep everything moving in the right direction (i.e. out of the body).

The ENS is autonomous. If the connection between the enteric nervous system and the brain is severed at the vagus nerve, the gut will continue to function as if nothing has happened. It will even continue to digest food – imagine that!  This is unique to the ENS and is found nowhere else in the body.

The gut is affectionately referred to as the ‘second brain’ and the conversation that takes place between the first brain and the second brain is actually a two-way-highway conversation, although it has to be said that 90 per cent of the conversation is from the gut to the brain. The vagus nerve is responsible for this.  The vagus nerve works like a telephone cable between the switchboard, or brain, and the gut. This makes the gut the largest sensory organ to the outside world.

BUTTERFLY FEELINGS

You don’t have to be a gastroenterologist to be aware of the more subtle feelings in your stomach that accompany emotions such as excitement, fear and stress. The second brain consists of sheaths of neurons embedded in the walls of the long tube of our gut, or alimentary canal. The second brain contains some 100 million neurons, more than in either the spinal cord or the peripheral nervous system. It is this multitude of neurons in the enteric nervous system that enables us to ‘feel’ the inner world of our gut.

‘Listening to your gut is a very visceral response; it is like having a sixth sense.’

As adults we have to practise letting go of the analytical and over- thinking mind and trust in our intuition, especially when it comes to assessing potentially threatening situations. The process of making decisions based on gut feeling may involve the gut recalling how it felt in similar situations in the past. This is why yoga and meditation are such good, effective practices – because they allow us to step back, drop the analytical mind and tune in to our intuition.

As I have developed my yoga and life practice, I have become convinced that as we humans have become increasingly more ‘civilised’, we have forgotten how to listen to our instinctual self. The net effect is that we have become distanced from our physical bodies and our guts. We have lost our connection with the rhythm of life and with our own internal rhythms and the rhythm of our own body mind.

When these three elements (mind, body and gut) are fully connected, you awaken a deeper connection to your authentic self; to the inner knowing of things that are not learned but are an innate part of you, encoded in your DNA: your real human nature. In this connected state you can begin to care for yourself and stop abusing your own body.
