The gut-brain axis is becoming clearer every day!

The gut is home to trillions of microorganisms - the gut microbiota. These microbes play a vital role in several physiological processes like digestion, immune response and neurotransmitter production. The composition and diversity of the gut microbiota can, therefore, influence brain function and mental health. An imbalance in the gut microbiota has been linked to conditions such as anxiety, depression, stress and reduced cognitive performance.

Let's take a closer look at these links between our gut microbiota, mental health and immune response.

Healthy gut microbiota food for mental health and improved immune response.

Gut Microbiota and Neurotransmitter Production:
The gut microbiota is involved in the production of neurotransmitters, including serotonin, dopamine, and gamma-aminobutyric acid (GABA). Serotonin, in particular, is a neurotransmitter that regulates mood and is often referred to as the "happiness hormone." About 90% of serotonin is produced in the gut. Disruptions in the gut microbiota can affect the production and availability of these neurotransmitters, potentially impacting mood and mental well-being.

Gut Microbiota and Immune System and Inflammation:
The gut has a significant impact on the immune system, and an imbalance in gut health can lead to chronic inflammation. Inflammation has been linked to various mental health disorders, including depression and anxiety. A healthy gut can help modulate the immune response and reduce systemic inflammation, potentially benefiting mental health.
Certain substances in our diet or an allergic reaction to certain ingredients can cause damage to the intestinal mucosa and thus increase intestinal permeability. The term "leaky gut" refers to increased intestinal permeability, which can lead to the passage of unwanted substances into the bloodstream. This can trigger an inflammatory response that might affect brain function and contribute to mental health issues. Maintaining a healthy gut barrier can help prevent these potential negative effects.

Gut Microbiota and Stress Response
The gut-brain axis is also involved in the regulation of the stress response. Chronic stress can impact gut health, and conversely, an imbalanced gut microbiota can affect how the body responds to stress. This bidirectional relationship can lead to a vicious cycle of stress and gut health issues, impacting mental well-being.

Gut Microbiota and Cognitive Function
Emerging evidence suggests that gut health may play a role in cognitive function and neurological conditions. A healthy gut has been associated with better cognitive performance and a reduced risk of conditions such as Alzheimer's disease.
Maintaining a balanced and diverse gut microbiota through a healthy diet, regular exercise, and stress management may contribute to overall well-being, including mental health.

Take care of your gut micro-helpers! You can maintain a healthy microbiota with the following measures:

• Eat a varied diet with different types of fibre
• Include fermented foods in your diet
• Limit processed foods and sugar
• Stay hydrated
• Manage stress
• Exercise
• Avoid overuse of antibiotics and unnecessary antibacterial products
• Get enough sleep
• Consider prebiotics and probiotics

Healthy gut and good mental health

In summary, the complex interplay of the gut-brain axis highlights the bidirectional impact between gut health and mental well-being. The role of the gut microbiota in neurotransmitter production, immune response modulation, stress regulation and cognitive function underscores its importance. By promoting a diverse gut microbiota through dietary choices, stress management and other factors, you can proactively manage both your physical and mental health.
