黑料正能量 Note: Below are two articles related to nutrition and its role in mental health; the second indicates a recent trial investigating adolescent nutrition and its impacts. Healthy nutrition changes play a role in recovery for many of our community members, but it is often talked about as something that people without serious diagnoses are concerned with to maintain health. The relationship between nutrition and the most extreme of mental health experiences is still unraveling, and more research is necessary. What is clear from emerging research, however, is that food has a serious role to play in the ability of our minds to process information and react to that information. Depression is often called, now, a 鈥渄isease of inflammation鈥, and recent studies indicate that unhealthy microbiomes can interact with other epigenetic factors to make individuals more susceptible to trauma, addiction, distracting or depressed mood patterns, and an overall lack of psychological resiliency.
How can our system get serious about the role nutrition plays in everyone鈥檚 options for recovery? How can we inform new solutions to poor mental health that start from the assumption that nutrition is a contributing factor to an individual鈥檚 experience? How can we create a biological model for mental health that is not shrouded in the myth of 鈥榗hemical imbalance鈥, and create one that is upheld by the need for healthy food to create an ideal biological environment for optimal mental health?

Julia鈥檚 TEDx Talk: Time to Get Serious About Nutrition
- Mad in America; Bonnie Kaplan, PhD and Julia Rucklidge, PhD, 11/18/2014
- 听
Julia鈥檚听TEDx talk,听鈥,鈥澨at the TEDx conference in Christchurch听on November 1st, was an opportunity to outline where we are now and some ideas of where we need to go. We are often asked to provide a single overview paper that will summarize everything there is to know about nutrition and mental health. Yet when we send review papers to people, it seems that they often do not have the time or interest to actually read the them.
Here are some of the main points from the talk:
- Based on any data from any country it is clear that we have a problem. Mental illness is on the rise.听 Rates of people on disability as a direct consequence of a mental illness are also on the rise. We can blame physicians and mental health professionals for overdiagnosing, we can blame our society for creating an environment that is conducive to developing mental illness, but however you look at it, our current approach to treating mental illness isn鈥檛 working. If a treatment is really effective then shouldn鈥檛 rates of disorder and disability caused by the illness be decreasing rather than increasing? And then there are the countless studies now documenting the role that psychiatric medications might be playing in some of these outcomes.
- Researchers in the emerging field of nutritional psychiatry have documented the benefits of micronutrients to treat mental illness, showing that micronutrients can reduce aggression in prisoners, slow cognitive decline in the elderly, help people overcome addictions, and help treat depression, stress, anxiety and autism and ADHD.
- People who eat 鈥榯raditional鈥 or 鈥榰nprocessed鈥 or 鈥楳editerranean鈥 or 鈥榩rudent鈥 diets have lower rates of depression and anxiety than people who eat 鈥榃estern鈥 or 鈥榩rocessed鈥 diets.Not a single study shows听that the Western diet is good for our mental health.听
Many questions remain to be answered by research on micronutrients and mental health. But with all of this rich data highlighting the power of nutrition, we can make some individual and collective changes now:
- Rethink our current treatment approach.听Prioritize lifestyle factors, healthy eating, exercise and psychological treatments and save medications for when these approaches don鈥檛 work. If nutrients work, then can the cost of these nutrients be covered through our public health care systems?
- Take universal prevention seriously听by optimizing nutrient intake of those who are vulnerable. In the world of physical health, we don鈥檛 wait until the heart attack hits to try to modify lifestyle behaviours that we know contribute to heart disease. It should be no different with mental health.
- Learn about the risks of eating processed cheap foods. As Michael Pollan stated, 鈥淐heap food is an illusion. There is no such thing as cheap food. The real cost of the food is paid somewhere. And if it isn鈥檛 paid at the cash register, it鈥檚 charged to the environment or to the public purse in the form of subsidies. And it鈥檚 charged to your health.鈥
- All children need to learn how to cook.听All children need to know that food doesn鈥檛 have to come in a packet.听Schools could reflect on the contents of their lunch menus.Children are too frequently rewarded with processed foods for good behaviour. Parents/teachers need to rethink whether this pairing intuitively makes sense. Ultimately, we have a responsibility to teach our children that every time we put something in our mouths, we make a choice to offer ourselves something nourishing or nutritionally depleted.
Nutrition matters. And if we鈥檙e really ready to get serious about mental health, it鈥檚 time to get serious about the critical role played by nutrition.
For those of you who might find the time to read a few key overview papers, we are taking this opportunity to recommend a few:

Broad-spectrum micronutrient formulas for the treatment of psychiatric symptoms: a systematic review.听Expert Review of Neurotherapeutics, 13(1), 49-73. doi: 10.1586/ern.12.143
- More and more people are interested in inflammation as the underlying mechanisms relevant to many forms of ill health.听 Here鈥檚 an excellent resource 鈥 and the title says it all: Berk, M., Williams, L.

So depression is an inflammatory disease, but where does the inflammation come from?听BMC Medicine, 11(1), 200.
- You have also heard terms (and not just from us!) like microbiome, oxidative stress, and mitochondrial function.

- We have told you previously about the formation of a new international society that is relevant to all of us: the International Society of Nutritional Psychiatry Research (ISNPR.org). Julia is a member of the ISNPR executive committee and has co-authored a statement about the mandate and scope of ISNPR which will be published any week now in听The Lancet Psychiatry.

Unhealthy Diets Linked to Depression in Children and Youth
- Mad in America; November 19, 2014
- 听
Children and adolescents who eat foods high in saturated fats, refined carbohydrates and processed foods appear to experience more depression and low moods, according to a review of twelve epidemiological studies across different countries published in the听American Journal of Public Health.
Led by Adrienne O鈥橬eil of the School of Medicine at Deakin University in Australia, the study included data on nearly 83,000 children from Australia, the United States, the United Kingdom and Norway. 鈥淲e found evidence of a significant, cross-sectional relationship between unhealthy dietary patterns and poorer mental health in children and adolescents,鈥 wrote the researchers. 鈥淲e observed a consistent trend for the relationship between good-quality diet and better mental health and some evidence for the reverse.鈥
鈥淭he evidence that poor dietary intake could be a risk factor for mental health issues in both adults and children is only very new 鈥 much of the data has emerged over the past seven years 鈥 thus widespread recognition is lacking,鈥 O鈥橬eill told听Medical Xpress.
鈥淕iven that the average age of onset for anxiety and mood disorders is six years and 13 years, respectively, the potential for early intervention using strategies targeted at improving dietary intake at a population level may be of substantial public health benefit,鈥 the researchers wrote. 鈥淗owever, this would require policy action to improve the global food environment.鈥
