5 Ways to Fortify Your Gut Bugs: A Science-Backed Guide to Transforming Mental and Physical Health

By Claire Russell  Registered Nutritionist, Clinical Medical Hypnotherapist, Mind Coach, Counsellor and Psychotherapist – Serving Limerick, Newcastle West Limerick, Midleton, Fermoy, Youghal, Cork, Dungarven and Online Nutrition, Hypnotherapy and Mental Health Therapy in Ireland, the UK, and Worldwide therapy remotely

Your Gut is the Gateway to Mental and Physical Health

Today, more people than ever are searching for ways to manage depression, anxiety, stress-related disorders, digestive issues, chronic fatigue, autoimmune diseases, IBS, brain fog, obesity, ADHD, and even skin conditions like eczema and psoriasis. What if one of the root causes—and solutions—is sitting right inside your digestive tract?

Your gut microbiome is an ecosystem of trillions of microbes, including beneficial bacteria, fungi, viruses, and yeasts, that live in your gastrointestinal tract. These bugs do everything from digesting food, balancing hormones, and regulating mood, to influencing your immune system and producing neurotransmitters like serotonin and dopamine that impact your mental health.

As a Registered Nutritionist, Clinical Medical Hypnotherapist, Counsellor, and Psychotherapist working with clients in Limerick, Cork, and through online therapy, I’ve helped hundreds of people overcome a wide range of mental health disorders and physical health issues by focusing on improving gut health and restoring microbiome balance.

Why Gut Health is a Priority in My Practice

Gut health plays a pivotal role in:

  • Depression and anxiety
  • Stress and emotional dysregulation
  • Chronic fatigue syndrome
  • Fibromyalgia treatment
  • Autoimmune conditions (e.g., rheumatoid arthritis, lupus, Hashimoto’s thyroiditis)
  • Hormonal imbalances (e.g., PCOS, PMS, Premenstrual dysphoric disorder PMDD, Endometriosis, perimenopause, menopause)
  • ADHD and autism spectrum disorders
  • Brain fog, concentration issues, and memory loss
  • Mood disorders and bipolar disorder
  • PTSD and trauma
  • Insomnia and sleep disorders
  • IBS and IBD (Crohn’s disease, ulcerative colitis)
  • Bloating and indigestion
  • Constipation and diarrhoea, Flatulence..
  • Weight gain, obesity, and metabolic syndrome
  • Type 2 diabetes and insulin resistance
  • High cholesterol and cardiovascular risk
  • Hypertension (high blood pressure)
  • Eczema, psoriasis, and rosacea
  • Acne, dermatitis, and hormonal skin issues
  • Asthma, allergies, and hay fever
  • Chronic sinusitis
  • Candida overgrowth
  • Leaky gut syndrome (intestinal permeability), SIBO, IBS, IBD, Crohns disease..
  • GERD and acid reflux
  • Recurrent infections, low immunity
  • Migraines and chronic headaches
  • Infertility, endometriosis, and reproductive disorders
  • Food sensitivities, gluten intolerance, and histamine intolerance
  • Yeast infections and urinary tract infections
  • Joint pain, arthritis, and musculoskeletal inflammation
  • Skin rashes, hives, and immune dysfunction

Each of these health concerns has been linked to dysbiosis—an imbalance in the gut microbiota. The good news? You can start rebalancing your gut today with science-backed strategies.

1. Eliminate Gut Disruptors

Modern life bombards us with substances that wreak havoc on gut flora:

  • Antibiotics (both prescribed and from conventional meat)
  • NSAIDs (non-steroidal anti-inflammatory drugs)
  • Antidepressants, antipsychotics, and other psychiatric medications
  • Proton pump inhibitors (PPIs) for heartburn
  • Oral contraceptives (birth control pills)
  • Artificial sweeteners (e.g., aspartame, sucralose)
  • Pesticides, herbicides, and glyphosate
  • Chlorinated tap water
  • Processed and ultra-processed foods
  • Refined sugar, glucose syrup, and white flour
  • Alcohol, caffeine, and energy drinks

These substances alter gut bacteria composition, inflame the intestinal lining, and reduce microbial diversity—leading to symptoms like bloating, mental fog, fatigue, mood swings, food cravings, and digestive discomfort.

2. Add Probiotic-Rich Foods and Supplements

Probiotics help restore gut flora, support digestive health, and boost both mental clarity and immune resilience.

Top probiotic foods:

  • Kefir (fermented milk or coconut)
  • Sauerkraut (unpasteurised)
  • Kimchi
  • Miso
  • Tempeh
  • Plain yoghurt (organic, unsweetened)
  • Kombucha tea

Key probiotic supplements should contain strains like:

  • Lactobacillus acidophilus
  • Bifidobacterium bifidum
  • Saccharomyces boulardii
  • Lactobacillus rhamnosus GG
  • Bifidobacterium longum

3. Feed Your Bugs With Prebiotics and Resistant Starch

Prebiotics are non-digestible fibres that fuel good bacteria, enhancing your body’s ability to produce short-chain fatty acids (SCFAs)—which reduce gut inflammation, improve mood regulation, and strengthen immune function.

Top prebiotic foods:

  • Onions, garlic, leeks, asparagus, artichokes, chicory root
  • Green bananas, apples, berries, kiwi, pears
  • Oats, barley, flaxseeds, chia seeds
  • Legumes (e.g., chickpeas, lentils, kidney beans)

Top sources of resistant starch:

  • Cooked and cooled potatoes or rice
  • Green plantains and bananas
  • Whole grains
  • Beans and legumes
  • Tigernuts, cashews, and peas

4. Spend Time in Natural Environments

Getting outside isn’t just for mental wellbeing—exposure to environmental microbes helps enrich your gut microbiome and promotes:

  • Reduced cortisol (stress hormone)
  • Enhanced parasympathetic nervous system activation
  • Better emotional regulation and immune balance

Try:

  • Hiking in woodlands and forests
  • Gardening, composting, and outdoor work
  • Barefoot walking (earthing)
  • Nature meditation

5. Grow Your Own Gut-Healthy Food

Growing your own organic produce enhances your connection to living food while boosting your exposure to soil-based organisms (SBOs).

Benefits of home-grown food:

  • No pesticides or herbicides
  • Higher nutrient content and microbial diversity
  • Better dietary fibre intake
  • Reduced chemical exposure

Even small herb gardens, windowsill planters, or community gardening can provide big benefits.

Final Thoughts: Your Gut as the Foundation for Lasting Change for Mental Health, Physical Health Issues, Emotional Health to Great Health and your happiness

Addressing your gut health isn’t just about digestion—it’s about creating lasting change in your mental health, emotional stability, immune resilience, weight regulation, and hormonal harmony.

Whether you’re struggling with anxiety, low mood, depression, stress, autoimmune conditions, inflammatory disease, chronic inflammation, acne, IBS, Hormonal Health, Weight Issues, Weight loss issues or fertility issues, your gut microbiome holds a vital key.
