Te Puna Toiora: Mental Health and Nutrition Research

The aim of our research group is to find nutritional interventions that are effective in treating psychiatric/psychological illness.

At our lab, we independently test new, groundbreaking multinutrient formulae, probiotics and other natural, beneficial substances. We run studies on many different psychological disorders, including ADHD (in both adults and children), addictions, depression and stress. We use all kinds of different trial designs to test these products, including multiple baseline designs, open label, and the ‘gold standard’ of clinical testing, the randomised, placebo-controlled trial (RCT).

We are not employed by the manufacturers of these products; we have no interest in getting a good result for them. All we’re interested in is finding real treatments that work, for the good of people affected by psychological illnesses.

Neville M Blampied is Professor of Psychology at the University of Canterbury, Christchurch NZ. His major research area for the past 20+ years has been in applied family psychology, notably pediatric sleep disturbances. Recently he has become concerned with methodological issues in research and has developed innovations in the visualization of data, incorporating aspects of the new statistics approach, that assist in understanding the outcomes of various psychological interventions.

In December 2012 he completed a 7-year stint as Head of Department (HoD) and member of the Executive of the College of Science, during which time he lead the Department’s research into the psychological effects of earthquakes. It is from this research that he developed a particular interest in the mental health benefits of nutritional and since retirement as HoD he has continued with active research in the Mental Health & Nutrition Laboratory.

He has also served as Director of Scientific Affairs for the New Zealand Psychological Society (2004-2010), as National President of the Association of University Staff (2000-2001), on the Board of the NZ Universities Academic Audit Unit (2001-2003), and was President, Division 6 of the International Association of Applied Psychology 2010 - 2014.

He has published ~ 100 peer-reviewed papers and chapters, and has supervised ~130 student theses and projects. He is currently co-editing a book on functional behavioural assessment and treatment of sleep problems in children with autism spectrum disorder, to be published by Sage.

Meredith is a PhD candidate within the Mental Health and Nutrition Research group. She completed her Master’s Degree in Psychology, exploring the ability of children to recognise and understand facial expressions of emotions.

Meredith became interested in the role of nutrition in mental health during her clinical psychology training. Her PhD project will be focused on investigating the impact of micronutrients on symptoms of anxiety and depression in adults, through a community-based, randomised controlled trial. Meredith’s other research interests include exploring feedback-informed treatment and best-evidence practice for anxiety disorders, particularly obsessive compulsive disorder.

Meredith is a registered clinical psychologist and has had experience working with adults experiencing a range of mental health issues including anxiety disorders, depression, substance abuse and dependence, adjustment, stress and offending behaviours. She is committed to assisting people with mental health issues in accessing appropriate, safe and effective treatments and enjoys helping clients explore the role of diet and nutrition within best-evidence treatment modalities.

Ben is a PhD candidate at the Mental Health Research Laboratory at the University of Canterbury, New Zealand.  He has a Masters degree in Holistic nutrition and is passionate about the effects of micronutrients on all aspects of health.  He is the founder and clinical director of BePure health, a scientific, holistic health company.

He is excited to be progressing the research of pyrroluria, a urine metabolite that has been said to bind zinc and B6 resulting in mental health disturbances.  His research bridges the fields of nutrition, mental health and metabolomics.  Stage one of the research involves establishing a new chemical assay to measure the molecule (HPL) in urine and then check binding potentials (in situ) with zinc and B6.  The main body of the PhD involves running a randomised, blinded, placebo, controlled trial with highly anxious people using high dose zinc and B6 as a treatment and levels of HPL as an outcome predictor. After his PhD is completed he plans to continue researching in the field of metabolomics, health outcomes and natural treatment options.

Hayley is a PhD student within the Mental Health and Nutrition Research Group at the University of Canterbury. She has a Bachelor of Science with Honours in Psychology from the University of Liverpool, UK and has worked in community mental health in New Zealand for five years before embarking on her PhD research.

As part of her PhD research, Hayley is coordinating a double blind, randomised, placebo controlled trial investigating the mental health outcomes of multi-micronutrient supplementation in pregnant women with low mood and/or anxiety and the general health outcomes of their child. Hayley is also excited to explore the mechanisms via which micronutrients exert their psychological effect by looking at inflammation and the association with antenatal mood and anxiety. Hayley hopes that this research will provide evidence of an alternative treatment option for pregnant women who are struggling with depression and/or anxiety and also contribute to our understanding of the mechanisms that may underpin the development and maintenance of psychological symptoms.

About our work

At the moment, our studies are only open to people who are not taking any psychiatric drugs. If you’d like to find out what trials we are running at the moment, or would like to take part, please visit the study pages above. If you’re not eligible for any of our trials, or you just feel as though you’d like a bit of support, please check out the Resources tab, where we have provided a list of counselling and other relevant services within Christchurch. For information about the products we study, please email Julia Rucklidge.

The range of the response to micronutrients can vary from a small but noticeable improvement to a substantial and dramatic life changing improvement. Based on short-term trials, about 50% show a meaningful and clinically important change. Others show a more modest improvement. A minority (probably about 20%) do not respond at all. Our research shows that the number of people responding goes up the longer they stay on the micronutrients. One appealing aspect of the approach is that people report very few side effects and they tend to be mild and transient. This research has been done on many different psychiatric conditions, ranging from bipolar disorder to ADHD to anxiety to stress.

All our studies have ethical approval from the University of Canterbury Human Ethics Committee and the Health and Disabilities Ethics Committee.

Our funding sources include: Canterbury Medical Research Foundation, Gravida, Vic Davis Memorial Trust, the GAMA Foundation, Foundation for Excellence in Mental Health Care, the University of Canterbury and a number of private donations.

    We are not dieticians and therefore are not in a position to offer dietary advice. However, we have put together some resources on food and local expertise in the hope that this information will be of use to the public.

    Harvard Medical School has put together lots of resources on healthy eating, including the healthy eating plate: www.health.harvard.edu/staying-healthy/healthy-eating-plate

    The Helfimed trial was a successful trial that showed benefit of assisting people suffering from depression to nudge over to a more Mediterranean-based diet. They have lots of recipes on their website: http://helfimed.org/cgi-sys/suspendedpage.cgi

    The Mood and Food Centre in Melbourne often blogs on diet-related topics. Check out their website: http://foodandmoodcentre.com.au/

    Dr Drew Ramsey has some excellent resources on eating well on a budget: https://drewramseymd.com/uncategorized/brain-food-budget/

    There are lots of great resources at this site: https://www.getselfhelp.co.uk/freedownloads.htm

    Books that we have enjoyed reading on nutrition and mental health that do have some scientific basis to their recommendations:

    • Finally Focused – Dr James Greenblatt
    • The Mad Diet – Suzanne Lockhart
    • The anti-anxiety food solution –Trudy Scott
    • What the FAT? - Prof Grant Schofield (also includes recipes)

    Rachel Kelly has devised a cookbook directly focused on eating foods that will contain nutrients help you feel mentally better:


    How to eat well on a budget:

    From the British Dietetic Association: A healthy diet can be more expensive than a diet made up of more refined foods. Fish, fruit and vegetables can be particularly pricey. However, by cutting down on sugary drinks and snacks, takeaways and alcohol, you can save money to be spent on healthier items. Take care to buy only as much as you know you can use within the next few days to reduce waste. You can also cut your costs by taking advantage of special promotions and by shopping at market stalls which are often cheaper than supermarkets.

    If you live alone you could save money by splitting purchases with friends (larger pack sizes are usually cheaper) or by cooking several portions of a dish and freezing some of them. This also saves fuel and saves you the effort of preparing meals every day. Frozen fruit and vegetables are often cheaper than fresh produce and are usually just as good nutritionally (with no wastage). Fresh fruit and vegetables are usually cheapest when they are in season while using beans, lentils and soy mince in cooking in place of meat can also cut costs.

    Also, research from Australia has shown that a Mediterranean style diet was cheaper than a poor quality diet.
