Mental Health Awareness Month, is a perfect time to talk about something that’s gaining more attention (and rightly so): the connection between your gut and your mental health. If you’ve ever felt “butterflies” in your stomach before a big moment or noticed your digestion suffers during periods of stress, you’ve experienced the gut-brain axis in action.
This article explores how gut health plays a vital role in regulating mood and emotional wellbeing. We’ll also share practical steps to support your mental health through nutrition and lifestyle, and how my nutrition coaching programmes can help you personalise your approach.
What Is the Gut-Brain Axis?
Think of the gut-brain axis as a two-way communication system between your digestive system and your brain. It’s not just about digestion, this intricate connection affects everything from your mood and memory to how you handle stress. In fact, your gut contains its own nervous system (called the enteric nervous system) and even produces neurotransmitters like serotonin and dopamine, which influence your emotional state.
How the Gut Microbiome Affects Mental Health
Inside your gut lives a vast and diverse community of bacteria known as the gut microbiota. These tiny organisms don’t just help digest food, they also regulate inflammation, support immune function, and influence brain chemistry.
When your gut is in balance, these microbes produce beneficial compounds like short-chain fatty acids (especially butyrate), which help reduce inflammation and improve brain function. But when your gut is out of balance, due to stress, poor diet, or illness, it can disrupt neurotransmitter production and contribute to anxiety, low mood, and even neuroinflammation.
This is particularly relevant for people with other chronic conditions like Parkinson’s Disease, where low dopamine levels affect motivation and emotional regulation. Supporting gut health becomes even more essential in these cases.
What Does the Research Say?
Studies now show that a disrupted gut microbiome can lead to changes in mood and behaviour. For example, research has found that transplanting gut bacteria from people with depression into rodents caused depressive-like behaviours. This strongly suggests our gut bacteria directly influence our emotional state.
Other studies show that patients with IBS and anxiety tend to have different gut microbes compared to those without these conditions. These findings highlight the importance of a diverse and balancedmicrobiome in supporting not just digestive health, but emotional wellbeing too.
Key Nutrients That Support Gut and Mental Health
If you’re wondering how to support your gut-brain axis through food, here are some essentials to include in your diet:
- Prebiotic-rich foods: Leeks, garlic, onions, oats, and bananas feed your beneficial gut bacteria.
- Probiotic foods: Fermented foods like kefir, sauerkraut, miso, and kimchi introduce helpful bacteria into the gut.
- Omega-3 fats: Found in oily fish, walnuts, and flaxseeds, these fats reduce inflammation and support brain health.
- B vitamins: Especially B6, folate, and B12, which are crucial for mood and neurotransmitter production.
- Tryptophan-rich foods: Turkey, eggs, and seeds help your body make serotonin.

Practical Tips for Supporting the Gut-Brain Axis
- Eat mindfully: Slow down at meals and chew thoroughly to aid digestion.
- Prioritise sleep: Poor sleep disrupts the gut microbiome and increases stress hormones.
- Move your body: Regular movement supports both digestion and mood.
- Reduce ultra-processed foods: These can disturb microbial balance and increase inflammation.
- Manage stress: Practices like deep breathing, meditation, and nature walks are proven to support both gut and brain health.
If you’re experiencing persistent low mood, digestive discomfort, or brain fog, your gut could be sending you signals. Exploring your gut health can open the door to deeper healing.
