The Microbiome-Gut-Brain Axis: What you need to know for brain and gut health

Until recently, we didn’t know how much our gut and brain interacted. Some people thought that our brains controlled everything we did, consciously and subconsciously.

They were wrong!

Some of us have a sense that there is a connection because we often feel emotions in our gut. For example, when we’re scared we can get a “knot” in our stomach. Or, feeling sad or anxious can affect our appetite and the number of bathroom trips we need to make. Plus, many digestive issues often come with mood issues.

Recent research confirms a gut-brain connection, a.k.a. “axis.” This microbiome-gut-brain axis is stronger and different than we had imagined. And with new technology, we’ve been able to study the gut microbes in a way that was not possible just a few years ago.

Let’s talk about how your gut microbes, your gut itself, your brain, and your mental health are all interconnected and influence each other! Plus, we’ll dive into some “mood foods,” as well as stress reducing activities that can help with gut issues.

The gut and microbiome

The microbiome-gut-brain axis: The observations

The microbiome-gut-brain axis: The nerve connections

The microbiome-gut-brain axis: The biochemical connections

The microbiome-gut-brain axis: The immune and inflammatory connections

Mood foods

What about probiotics?

Reduce stress for your gut


There is a tonne of research digging into these vast and varied interconnections between our gut and our brain. The microbiome-gut-brain axis consists of nerves, biochemicals, and the immune system. This axis is a hotbed of research to try to really understand how our “second brain” affects our moods and vice versa.

There are a number of foods that we can feed our gut that can help our moods, and reducing our stress can have a significant impact on several digestive diseases.

The microbiota-gut-brain axis is an active area of research now. Make sure you treat your gut and your brain well.
