Alzheimers and the Gut Brain
Did you know that your gut health could be influencing your brain’s future?
Groundbreaking research suggests that the path to protecting our cognitive health might start in a place you might not expect– our digestive system.
As a dietitian with over three decades of experience at 121 Dietitian, I’ve witnessed firsthand how our digestive system influences overall wellbeing, particularly brain health.
Let me share some groundbreaking insights that could transform your approach to cognitive wellness.
The Growing Crisis in Numbers
In the UK alone, over 944,000 people are living with dementia, with Alzheimer’s disease being the most common form. By 2040, this number is projected to double (Alzheimer’s Society, 2024).
Behind these statistics are real families facing real challenges – something I’ve seen countless times in my Holywood clinic.
The Gut-Brain Axis: Understanding the Connection
Ongoing research identified a two-way communication system between our digestive system and brain.
This is known as ‘gut-brain axis’ and is a crucial pathway that might hold the key to preventing cognitive decline.
The Bacterial Blueprint: Key Players in Brain Health
Through my clinical experience and continual research, I am always interested in the details so it is exciting to see specific bacterial strains identified that play crucial roles in cognitive health including the following:
- Bifidobacterium longum
- Reduces brain inflammation
- Strengthens gut barrier function
- Supports neurotransmitter production
- Lactobacillus plantarum
- Enhances memory performance
- Reduces oxidative stress
- Supports overall brain function
- Akkermansia muciniphila
- Improves cognitive function
- Maintains gut integrity
- Reduces neuroinflammation
It is important to acknowledge also the significant role gut bacteria plays in mental health, a topic you can explore further in the following blog.: Mental Health and Diet: Exploring the connection.
Essential Nutrients for Brain Protection
Wild Omega-3 Nordic Fish Oil is a great option for supporting brain health, especially for those with memory concerns.
It’s packed with high-strength DHA & EPA, essential for cognitive function and cell repair. Sourced from wild-caught Nordic fish and third-party tested for purity, it’s a clean, reliable choice. Plus, the fresh lemon flavor means no fishy aftertaste—making it easier to take daily. A simple way to help nourish the brain and support long-term memory health.
As Omega-3 fatty acids, particularly DHA and EPA, are crucial for maintaining brain health. I recommend this to all my suitable patients:
Premium Omega-3 Fish Oil ✓ High-strength DHA/EPA formula ✓ Third-party tested ✓ Sustainable sourcing ✓ Wild Omega -3 Nordic Fish Oil is available via our 121 Dietitian specialist Amazon shop

Real Results: A Client’s Journey
Sarah’s Story – A Life Transformed
At 52, Sarah arrived at our Holywood clinic feeling lost and overwhelmed. She had been battling a constant brain fog, making even the simplest tasks feel like a struggle.
Her digestive system was in turmoil, leaving her bloated, uncomfortable, and frustrated after every meal. She found it increasingly difficult to focus at work, and her concentration had dwindled to the point where she feared she was losing control of her own mind.
What weighed on her most was a family history of dementia—a silent fear that had been growing in the back of her mind for years.
She felt alone in her struggles, afraid that her body was failing her, and unsure of where to turn for real answers.
The Turning Point: A Life-Changing Decision
Sarah took a leap of faith and booked our 121 Dietitian Gut Health Program, designed to restore balance and rewire the body from the inside out. Through a tailored approach of:
✅ Personalised dietary modifications
✅ Targeted supplementation
✅ Education on gut-brain connections
✅ Guidance on inflammation and long-term health
Sarah fully committed to making the changes. It wasn’t always easy, but with the right support and clear guidance, she began to see shifts she never thought possible.
The Transformation: A New Beginning
Weeks later, Sarah returned with a new sense of hope—she was relaxed and delighted with her results.
✨ Her brain fog had lifted, allowing her to think clearly, recall information with ease, and regain confidence in her abilities.
✨ Her digestive symptoms had completely resolved, meaning no more bloating, discomfort, or unpredictable gut issues.
✨ Her work performance soared—she was more productive, focused, and engaged than she had been in years.
✨ Her sleep improved, and her mood became lighter, replacing anxiety with calm and deep, restorative rest.
For Sarah, this wasn’t just a gut health program—it was a second chance at life.
She no longer feels trapped by her body, afraid of what the future holds. Instead, she feels empowered, healthier, and in control.
