The gut-brain axis: how it works and the role of nutrition

Are you familiar with the gut-brain axis? If you’ve ever felt ‘butterflies’ at the sight of a loved one, or lost your appetite when you’ve been stressed, you might be aware that your mind and stomach are connected. But the gut-brain axis is a real phenomenon, and this constant two-way communication, when out of sync, can trigger gut and other health-related issues.

By and large, the gut-brain axis is a communication system between the brain and the trillions of bacteria, fungi and viruses living within your intestines. multiple studies have shown that the composition of gut bacteria can have a profound impact on mental health and the functioning of the nervous system. A healthy diet plays a significant role in shaping this microbiome by promoting the growth of beneficial bacteria and stopping the accumulation of harmful ones. Nutrition can also influence the communication along the gut-brain axis, further affecting the links between the gastrointestinal tract and the nervous system.
