What Is The Gut-Brain Axis?

Ever heard the phrase ‘trust your gut’? Well, science says there’s actually more truth to that than you might think. Your gut and brain are constantly chatting away, influencing everything from your mood to your digestion. This fascinating conversation is called the gut-brain axis, and understanding it could be the key to better mental and physical wellbeing.

How Are the Gut and Brain Connected?

The gut and brain are in constant communication, influencing everything from mood and stress levels to digestion and overall health. This connection relies on several key pathways, including the vagus nerve, neurotransmitters and the trillions of microbes living in your gut.

The vagus nerve acts as a direct communication highway between the gut and brain, while neurotransmitters like serotonin - many of which are produced in the gut - help regulate mood and emotions. Meanwhile, the gut microbiome plays a crucial role in this relationship, affecting brain function and mental well-being. But how exactly does this complex system work? Let’s take a closer look.
 

The Role of the Vagus Nerve

Think of the vagus nerve as the ultimate messenger service. This nerve runs from your brainstem all the way (through organs like your heart and lungs), down to your intestines, carrying signals between the two. It helps regulate digestion, mood, and even heart rate.
 

The Impact of Neurotransmitters

Your gut approximately produces a whopping 90% of the body’s serotonin. But what actually is serotonin? It’s a neurotransmitter which is like a chemical messenger that helps to control your mood. In short, a happy gut helps to keep a happy mind.
 

The Influence of the Gut Microbiome

Inside your gut, live trillions of microbes, collectively known as the microbiome. These tiny bacteria influence everything from digestion to immunity and even play a role in mental health.

 

Why Is Gut Health Important for Mental Wellbeing?

When your gut microbiome is out of sorts, it can lead to inflammation, which has been linked to anxiety, depression and even brain fog. Therefore ensuring a well-balanced gut can help keep stress levels in check, boost your mood and support cognitive function.

 

How to Support a Healthy Gut-Brain Connection

If you’re wondering what you can do to improve your gut health, then creating simple habits like eating well, managing stress and prioritising sleep can make all the difference. Here’s how to keep your gut and brain in sync.

 

Eat a Gut-Friendly Diet

Load up on probiotic-rich foods like yoghurt, kefir and sauerkraut. These fermented foods contain ‘good bacteria’ that create better diversity in our gut microbes. Don’t forget fibre-rich foods like whole grains, bananas and onions – these feed good bacteria in your gut and help move things along if you’re feeling a little backed up!

 

Manage Stress Levels

If your body is under stress for long periods of time (known as chronic stress) it can throw your gut out of balance. Try activities like meditation, deep breathing or going out in nature can work wonders for your brain-gut connection.

 

Get Enough Sleep and Exercise

Sleep deprivation or lack of movement can both disrupt your gut health. Of course, every person is different, but on average, we should be aiming for 7-9 hours of sleep a night and regular movement to keep our gut - and ultimately your mind - happy!
