Brain Nutrition: How Food Influences Your Mood.

Posted 17 February



Did you know our brains need calories? The brain indeed uses about one-fifth of our body’s total calories. While our brains are brilliant machinery, their needs are relatively 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 change our brains’ structure and health. So let’s talk about 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) directly results from how we think and feel. So our brains will only go based on the information you are giving access to from Step 1 – How you think. So ask yourself what information you are 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, cognitions, thought patterns, feelings, behaviour, or mood. To save you from reading decades of research on therapeutic modalities and dietary requirements for achieving this, we have set out below our Top 4 favourite nutrient-rich foods, backed by scientific evidence.

Omega 3 and Fatty Acids

Oily fish and seafood are good sources of marine-source Omega 3, including long-chain fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Try not to get overwhelmed by their complicated names – they are essential for eye development and for rebuilding and renewing body and brain cells. After five years, brain development and the Central Nervous System (CNS) require fewer DHA. Forr children, this is a perfect age to start integrating EPAs as it can support their academic performance, focus, attention, behaviour, and anger aggression. Oily fish is also beneficial 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 and 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 some strawberries, blackberries, blueberries, blackcurrants or mulberries on your next visit to the grocery.


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


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

Other Brain-Boosting Foods that we love:

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

Here at Brain Training Australia™ in Perth, we see clients of all ages, from young children to older people attending, with cognitive and behavioural issues such as anger, frustration, agitation, temper tantrums, getting nervous quickly, 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 instance, they might be elite athletes or business professionals and need to perform to the best of their ability.

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

So we focus on Step 1 How you think. We are the only Clinic in Perth offering non-linear (non-medical) Neurofeedback Brain Training to retrain the brain’s activity which can regulate how you feel. Couple this with a nutrient-rich diet like the above foods, 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 peak performance-related issue, as mentioned above, you must contact a Certified Professional using methods 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 contact our team of Certified Professionals at Brain Training Australia™ to give your brain the boost it needs.
