Brain Nutrition: How Food Influences Your Mood.

Posted 17 February

-By Elaine Corcoran, Founder of Brain Training Australia™ in Perth

Did you know our brains need calories?  It’s true, in fact the brain uses about one fifth of our bodies total calories.  While our brains are extremely intelligent pieces of machinery, its needs a fairly simplistic.  We all know that old saying “you are what you eat” but when it comes to our brain development and well-being, what we eat can actually change the structure and health of our brains.  So let’s talk nutrients and how we can fuel our brains.

How you think (Step 1)

becomes how you feel (Step 2)

becomes how you behave (your mood) (Step 3)

Our output behaviour (or how we behave) is a direct result of how we think and how we feel.  So our brains will only go on the basis of the information that you are giving it access to from that Step 1 – How you think.  So ask yourself what information are you giving your brain access to? Is it time to change that information or are your Steps 1, 2 and 3 allowing you to be your optimal self?

You can change and influence How You Think (Step 1) to improve your brain cells, your cognitions, thought patterns and in turn your feeling and behaviour or mood.  To save you reading decades of research on therapeutic modalities and dietary requirements on how to achieve this, we have set out below our Top 4 favourite nutrient rich foods which are backed by scientific evidence.

Omega 3 and Fatty Acids

Oily fish and seafood are both a good source of marine-source Omega 3 which include long-chain fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).  Try not to get overwhelmed by their complicated names – they are basically essential for eye development and for not only rebuilding and renewing body cells, but brain cells also. After the age of 5 years, the brains development and the Central Nervous System (CNS) require less DHAs, so for children this is a really good age to start integrating EPAs as it can support their academic performance, focus, attention, behaviour, anger and aggression. Oily fish is also really helpful for reducing inflammation, dry skin conditions, asthma and allergies.  As we age, low EPA can result in mental health issues such as anxiety, depression, attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD), alongside dyslexia, dyspraxia, heart problems, cognitive decline and dementia, joint and bone conditions, neurodegenerative diseases such as MS and Parkinson’s. 

So there has never been a better reason to tuck into some salmon, mackerel, tuna, herring, sardines, soybeans, nuts and flaxseeds.


Containing flavonoid antioxidants such as anthocyanin, caffeic acid, catechin and quercetin, these antioxidants can improve the communication between brain cells, increase plasticity which supports the creation of new neural networks in the brain – linking in beautifully with our speciality of Neurofeedback Brain Training – berries can boost your learning and memory, reduces inflammation throughout the body and reduces or delays age-related neurodegenerative diseases and cognitive decline.

So be kind to your brain and grab yourself some strawberries, blackberries, blueberries, blackcurrants or mulberries in your next visit to the grocery.


Full of monounsaturated fats, avocados contribute to healthy blood flow and lower blood pressure, thus promoting a health brain. They are also a good source of unsaturated fats which can support the brain function and lower the risk of cognitive decline.  If you don’t like avocados then don’t worry, there are plenty of other options for unsaturated fats such as taking almonds, walnuts, brazil nuts, flaxseed, chai seeds, cashews, peanuts, soybean, sunflower oil and fish.


A great source of protein, folic acid, vitamin B6, vitamin B12 and choline which all really important for healthy brain functionality and development.  Let’s focus specifically on choline for a moment, it is an important neurotransmitter for mood, memory, muscle control and nervous system functions.  As we get older, the consumption of eggs have been proven to prevent brain shrinkage and delay cognitive decline.

Other Brain Boosting foods which we love:

  • Wholegrains – oates
  • Legumes for iron, folate, protein, fibre, calcium, lentils, chickpeas, beans, peas.  Folate reduces developmental issues, infections and disease.
  • Protein and calcium including dairy and yoghurt.  Probiotics reduces developmental issues and allergies.
  • Water
  • Lastly, – Leafy Greens such as broccoli, kale, spinach, fibre, Vit C, K A, Calcium, Iron, Folate, Potassium to boost the immune system.

Here at Brain Training Australia™ in Perth, we see clients of all ages from young children to the elderly attending with cognitive and behavioural issues such as anger, frustration, agitation, temper tantrums, get nervous easily, nail biting, fidgeting and getting annoyed at others easily for example. We also have a lot of clients attending for peak mental performance reasons, for example they might be an elite athlete or business professional and need to be able to perform to the best of their ability.

Your behaviour, or mood can be caused as a direct result of How You Think (Step 1) which then influences how you feel (Step 2).  So we are not interested in putting a bandaid on the problem, for some people that can be suffice, however we are more concerned at getting to the root cause of the issue. 

So we focus on that Step 1 How you think.  We are the only Clinic in Perth offering non-linear (non-medical) Neurofeedback Brain Training to retrain the brains activity which can regulate how you think.  Couple this with a nutrient rich diet such as the foods listed above and you are on to a winning combination to give your brain the best possible outcome.

If you, or someone you know is struggling with a mental health or mental peak performance related issue as mentioned above, it is very important that you contact a Certified Professional using methods that are grounded in clinical research, to overcome your psychological or emotional challenges. A nutrient rich diet is a no-brainer (pardon the pun..), coupled with Neurofeedback Brain Training you are giving yourself the best possible option to thrive. We would love to support you on your journey, so please do not hesitate to get in touch with our team of Certified Professionals at Brain Training Australia™ to give your brain the boost it needs.
