Your mood is
influenced by
what you eat
The connection between food and mental wellbeing is one of the best-supported areas in modern nutritional science, and one of the most underused tools available to you.
When your mind and body don't feel like themselves
Mental wellbeing isn't separate from physical health. These are experiences that often have a real nutritional component people don't realise is there.
Low mood, persistent flatness, or feeling disconnected from enjoyment
Anxiety or a sense of being on edge that never fully goes away
Brain fog, slow thinking, or difficulty concentrating for any length of time
Irritability or a short temper, especially when hungry or tired
Disrupted sleep: trouble falling asleep, staying asleep, or feeling restored
Energy and motivation that swings wildly, or is consistently low
Using food for emotional comfort, and feeling stuck in that pattern
Stress that feels unmanageable, or a sense that your resilience has dropped
None of these mean you're broken. Many have real, addressable nutritional underpinnings, and working on those can genuinely shift how you feel, often faster than people expect.
Why nutrition and mental health are inseparable
Nutritional psychiatry is a relatively new but rapidly growing field, and the evidence is compelling. What you eat directly influences the production of neurotransmitters like serotonin and dopamine, the function of your stress response, and the health of the gut–brain axis.
My background spans both nutritional science and psychology, which means I understand the mental health side of this picture rather than only the nutritional one. That intersection is where the useful work happens.
of your serotonin is produced in the gut rather than the brain.
The gut–brain connection runs in both directions, with each system continuously influencing the other.
Higher-quality dietary patterns are consistently associated with reduced depression risk in the research.
Nutrition and psychology, together
This isn't about eating more leafy greens and hoping. It's a structured process that looks at the specific nutritional and behavioural factors affecting your mental wellbeing, and addresses them in a way that fits your life.
My psychology study alongside specialist clinical nutrition training means I can work with both sides of this picture: the emotional and psychological dimensions of eating as well as the biochemistry.
Neurotransmitter support through food
Serotonin, dopamine, GABA and the rest are built from what you eat. We look at whether your diet is supplying the building blocks those systems need, and where the gaps are.
Gut health and the gut–brain axis
A healthy microbiome produces neurotransmitters, regulates inflammation and communicates directly with the brain. If your gut isn't happy, your mood often reflects it, so we work on both ends.
Blood sugar and mood stability
Blood sugar crashes are one of the most common and least recognised drivers of anxiety, irritability and low mood. Stabilising glucose through food choices and meal timing often shifts how you feel noticeably quickly.
Stress, cortisol and nutritional resilience
Chronic stress depletes magnesium, B vitamins and vitamin C, which is exactly what your nervous system relies on. We look at what your stress load is doing to your nutritional status and build in targeted support.
The emotional side of eating
Food and emotion are deeply intertwined. I work with the psychological patterns around eating as well as the nutritional content, because addressing one without the other usually doesn't stick.
Mindfulness and the foundations
My yoga teacher training and mindfulness background inform how I approach the non-food side. Sleep, movement, breath and rest all interact with nutrition and all have a place in the picture.
The hour is the smallest part
Every consultation includes a full written clinical protocol, and that protocol takes three to four hours to build after you've logged off. The hour is where I gather the case. The work happens after it.
The consultation
Symptoms, health history, medications, bloods, and what you actually eat on a normal Tuesday, not an idealised version of it.
Research and case review
Your case worked through against the current evidence: what's likely driving it, what the research supports for your situation, and any interactions with your medications.
Your wellbeing protocol
Diet, lifestyle and supplement recommendations with specific forms, doses and timing, plus the reasoning behind each, so you can question it rather than just follow it.
Yours to keep
A document you own and can come back to in six months, or hand to your GP. Nothing depends on how well you took notes.
Who I work with
Nutritional support for mental wellbeing works best alongside other care, not instead of it. If you're already working with a GP, therapist or counsellor, that's a good foundation. A good fit if you're:
- Experiencing low mood, anxiety or stress and wanting to know what nutrition can do to support it
- Already seeing a therapist or GP and wanting to address the nutritional side alongside that care
- Noticing your mood, energy and concentration fluctuate with what you eat, and wanting to understand why
- Dealing with emotional eating or food–mood cycles that are affecting your wellbeing
- Going through a period of high stress or burnout and wanting nutritional support while your body copes
- Wanting to be proactive about mental health, using food as a genuine tool before things get harder
An important boundary
Nutritional support complements mental health care. It does not replace psychological therapy, psychiatric care, or medication where those are needed.
If you're in crisis, or experiencing serious depression or anxiety, please contact your GP or a mental health professional first. In an emergency in New Zealand, call or text 1737 to reach a trained counsellor free, any time. I work alongside that care, never in place of it.

“My two sessions with Luke were exactly what I needed. He had a beautifully eloquent way of explaining some of the science behind what I was experiencing — which was equally validating as it was motivating. Months following my sessions I'm a new version of myself. My mental and physical well-being have improved tenfold.”Client — Auckland
Nutrition and mental health questions
Can changing my diet really affect my mood?
Yes, and the evidence has strengthened considerably over the last decade. Diet quality is consistently associated with depression risk in large studies, and there are clear mechanisms: neurotransmitter precursors, gut microbiome, inflammation and blood sugar stability.
What it can't do is fix everything on its own, and I'd be sceptical of anyone claiming otherwise.
Will this replace my therapy or medication?
No. Nutrition sits alongside psychological therapy and psychiatric care, and I'd actively encourage you to keep both.
Never stop or change prescribed psychiatric medication without your prescriber. Withdrawal from antidepressants in particular needs proper medical supervision.
How quickly might I notice something?
Where blood sugar instability is a factor, and it often is with irritability and anxiety, people frequently notice a difference within one to two weeks.
Deeper changes involving the microbiome or nutrient repletion take longer, usually eight to twelve weeks. Individual results vary.
I'm on antidepressants. Does that change anything?
It's useful for me to know, both because some medications affect appetite and weight and because a few have specific nutritional interactions worth checking.
Part of the research time on your protocol goes into confirming nothing I recommend interacts with what you're taking.
Do you provide counselling or therapy?
No. I have psychology study behind me and it informs how I work with behaviour and the emotional side of eating, but I'm a nutritionist, not a therapist or psychologist.
If what you need is therapy, I'll say so and help you find it.
Not sure where nutrition fits?
Fifteen minutes, free, no obligation. Tell me what you're experiencing and what support you already have, and I'll be honest about whether this would add anything.
