How Diet Affects Brain Function

Did you know that what you eat or do not eat… affects your brain function? Crash course time. Our diets can drastically affect our mood, focus, vitality, decision-making abilities, stress management, memory and concentration.

A diet rich in a variety of proteins, micronutrients, and healthy fats, when sustained can make all of the difference in reaching our mental potential. Additionally, what we eat can also take a toll on our brains and bodies, so let’s talk about foods that help optimise function as well as minimise damage.

Let’s start with a smashing fruit!


These are loaded with Vitamin K and folate which improve the flow of blood and oxygen.


Antioxidants and gallic acid protect the brain from oxidative stress resulting in boosted concentration and memory and increased blood/oxygen flow.

Seeds and Nuts

Vitamin E (antioxidant) and choline (precursor to acetylcholine help with drive and focus).


Jam-packed with Vitamin K and a tonne of nutrients including fibre, Vitamin C, iron, and potassium. It also boasts more protein than most other vegetables and has powerful plant compounds, including antioxidants.

Dark Chocolate

Rich in magnesium which helps manage stress and stimulates neurotransmitters with a small amount of caffeine.


Choline and B Vitamins for memory, focus and brain health.

Flax Seeds

A source of Vitamin E which protects us from cognitive decline, as well as magnesium and B Vitamins. Make sure to grind to improve digestion.

Green Tea/Yerba Mate

includes caffeine and l-theanine, which increases alpha wave activity (leading to calmness and clarity).

Leafy Greens

Magnesium, antioxidants, B Vitamins and carotenoids, help prevent dementia and optimise brain function. Folic acid may aid mental clarity.

Fatty Fish

Omega 3s keep brain function optimal (clarity, focus, memory, mood). Sources include Salmon, trout, mackerel and sardines.

There are so many foods that help keep your brain super healthy. Many foods, such as fruits and vegetables and even chocolate, tea and coffee, have antioxidants that help protect your brain from damage.

Others, such as nuts and eggs, contain nutrients that support memory and brain development. By adding these into your diet, you can help support your brain health, boost your alertness, memory and mood. Let’s fire up our brainpower!
