The Gut-Brain Connection: A New Frontier in Mental Health Care
Our understanding of mental health is always evolving. Just when we think we’ve got it all figured out, along comes another perspective to remind us how connected everything really is—our minds, bodies, and experiences all working together to shape our overall wellness (or lack thereof). I totally get the mix of curiosity and mild annoyance when clients and practitioners alike realize, “Wait, I need to care even more about what I eat...because trauma? Seriously?” But honestly? It makes so much sense when you really break it down.
I get it—this gut-brain connection stuff can feel like a lot at first. But think about it: what if that nervous butterfly feeling in your stomach isn’t just a side effect, but a key player in the whole equation? And what if supporting your clients’ physical health—especially their gut health—could actually strengthen their emotional resilience and enhance the work you’re doing together? For mental health professionals, the gut-brain connection opens the door to a more holistic, whole-body approach to healing, and that’s an opportunity worth exploring.
Now, I'm not saying you should all become expert nutritionists overnight. But as health professionals, we owe it to our clients to at least consider the gut-brain connection as a serious gateway to better mental health outcomes. It's opened up a whole new way of thinking about healing for me and my clients, and I am certain it could for you too.
In this post I'll share what I've learned about the science behind it, some practical strategies I've used with my clients, and how understanding this link has sincerely reshaped my entire approach to mental health care.
The Gut-Brain Axis: A Two-Way Street for Healing
The concept of the gut-brain axis has been gaining attention in both medical and mental health fields. But what exactly is it? The gut-brain axis is a communication network that links the central nervous system (which includes the brain) with the enteric nervous system (which governs the digestive tract). This system allows the gut and brain to "talk" to each other through hormones, nerves, and even gut bacteria.
How It Works:
The gut produces neurotransmitters, such as serotonin, dopamine, and GABA, that directly influence mood and cognition. In fact, the gut is responsible for producing around 90% of the body’s serotonin. This means that disruptions in gut health—like inflammation, imbalances in gut bacteria, or poor digestion—can significantly impact mental health.
Did you know? Individuals with Irritable Bowel Syndrome (IBS) are more likely to experience anxiety or depression. Studies suggest that this is due to inflammation in the gut triggering emotional distress through the gut-brain axis.

The Impact of Gut Health on Anxiety, Depression, and Cognitive Function
When clients come to you with anxiety, depression, or mood disorders, it’s easy to focus solely on cognitive and emotional triggers—that’s you’re training. But often, their gut may be contributing to their mental health challenges and your best efforts are hitting (digestive) walls you can’t see.
How Gut Imbalances Affect Mental Health:
Inflammation: Chronic gut inflammation can release pro-inflammatory cytokines that cross the blood-brain barrier, contributing to anxiety and depression. A study in the Journal of Clinical Psychiatry found that individuals with elevated inflammation markers had higher rates of depression.
Gut Microbiome: An imbalance in gut bacteria—called dysbiosis—has been linked to increased cortisol production (the stress hormone) and reduced neuroplasticity, which affects emotional regulation and resilience.
Practical Example:
Imagine a client who struggles with depression but also experiences regular bloating, indigestion, or constipation. While therapy addresses the emotional aspect of their depression, adding a focus on gut health can target the physical root causes. Healing their gut may relieve both their physical discomfort and mental distress, giving them a better chance for long-term recovery.
The Role of Functional Health Coaching in Mental Health Practices
Now that we understand the importance of gut health, the next step is how mental health professionals can practically incorporate it into their work. This is where Functional Health Coaching comes into play. Functional health coaches work to uncover the root causes of gut imbalances through a personalized approach, making them a valuable asset to therapy and your practice.
What Can Functional Health Coaches Do?
Dietary Analysis: Identify foods that may be causing inflammation or gut imbalances. For instance, highly processed foods and sugar can increase gut inflammation.
Lifestyle Assessment: Examine stress levels, sleep patterns, and exercise routines—all of which play a role in gut health.
Supplementation: Recommend gut-friendly supplements such as probiotics, digestive enzymes, or anti-inflammatory foods like turmeric.
Integrative Therapy:
As a mental health professional, collaborating with a functional health coach means you’re offering a truly holistic treatment plan. While therapy can address emotional triggers, functional health coaching can tackle physical issues like inflammation or gut imbalances that may be exacerbating mental health symptoms.
A 2021 study found that individuals who followed a gut-healthy diet (rich in fiber and probiotics) experienced a 30% reduction in anxiety and depression symptoms compared to those who didn't.
The Magic of Broths for Gut Health
Broths, particularly bone broth, are packed with gut-healing nutrients like collagen, gelatin, and amino acids that support digestion, reduce inflammation, and help repair the gut lining.
The Gut-Mind Connection in Action: Real-Life Benefits for Clients
So, what does this look like in practice? Let’s explore how incorporating gut health can transform your therapeutic approach.
Example #1: Anxiety and Stress Management
Consider clients dealing with high levels of anxiety. While cognitive techniques like mindfulness or CBT can help, addressing gut health may also reduce their overall stress responses. Chronic stress is known to disrupt gut bacteria like you wouldn’t believe, leading to the sort of heightened cortisol levels that carve the perfect path to poor health. A functional health approach may involve:
Introducing gut-friendly foods to support serotonin production.
Suggesting probiotics or fermented foods to balance gut bacteria.
Recommending yoga or deep breathing exercises to lower gut-related stress markers.
Example #2: Trauma Recovery
For clients recovering from trauma, the gut can play a shocking role. Trauma can trigger the “fight or flight” response, leading to digestive issues, chronic inflammation, and hormone imbalances. Addressing these through functional health could include dietary changes, stress management techniques, and even specific supplements to help reduce inflammation.
Case Study: A client who experienced childhood trauma was suffering from chronic IBS and depression. After working with a functional health coach, it was discovered that her diet was causing inflammation that triggered both digestive and emotional distress. By eliminating certain trigger foods, introducing gut-friendly supplements, and incorporating stress reduction techniques, her IBS symptoms diminished, and she experienced a noticeable improvement in her mood.
Getting Started: How to Introduce Gut Health into Your Practice
It’s natural to feel unsure about integrating physical health into a mental health practice, it’s not your wheelhouse and cross-disciplinary collaboration is still a newer concept. But the benefits are clear: better care looks like this. Here’s how you can begin with confidence in implementing your future health collaboration plans:
Step 1: Start the Conversation Simply
Ask straightforward questions about your client’s digestion, stress, and diet. Are they mentioning bloating, fatigue, or digestive discomfort? Do they notice their mood changes when eating a particular way? We tend to only ask food questions in mental health as they pertain to disordered eating or body image issues when food is a much larger subject in overall emotional function and dysfunction. The more we know the better.
Step 2: Refer to a Functional Health Coach
If gut health seems to be playing a role in their mental well-being, suggest working with a functional health coach like Brooke to dive deeper into the gut-brain connection. With a few forms and a thorough intake you’ve set you on and your client on a clearer path to seeing the efficacy of your therapies without these invisible barriers in your way.
Step 3: Holistic Treatment Plans
Encourage clients to keep a food-mood journal to track how their diet affects their emotions. This can be a powerful tool in therapy and functional health coaching, helping identify triggers that are causing therapy goals to stall out.
What the Future Holds for Mental Health Care
The gut-brain connection is still a growing field of research, but it holds incredible potential for mental health professionals. By broadening your understanding of the physical contributors to emotional well-being, you’ll not only enhance your client’s therapy experience but also make their quality of life better. Partnering with functional health coaches and learning more about the gut-mind connection is a dynamic step toward offering truly holistic care. If better care is collaborative, there’s no time like to present to be at the forefront of creating a blueprint for your practice that becomes the standard in gold-star care.
Your Next Steps
As we continue to learn more about the gut-brain axis, it’s clear that mental and physical health are more connected than ever imagined. Integrating gut health into your mental health practice offers your clients a new, more comprehensive approach to healing. By collaborating with functional health coaches like Brooke, you can provide your clients with the full spectrum of care they deserve.
