Brainfit Tricks For ’26 – Part 6:
Throughout 2026 we’re sharing 52 weekly, science-backed Brainfit Tricks designed to strengthen memory, sharpen focus and build greater confidence at any age. Welcome back to Brainfit Tricks for ’26. This month, we’re focusing on another essential pillar of brain health: Nutrition.
Food is fuel – not just for your body, but for your memory, mood and mental clarity too.
Every time you eat, you’re providing the building blocks your brain uses to think, learn and remember. And while nutrition advice can often feel confusing or overwhelming, supporting your brain doesn’t require a perfect diet or giving up all your favourite foods.
At Brainfit, we believe it’s about progress, not perfection. Small, brain-friendly food choices, repeated consistently over time, can add up to big benefits. That’s exactly what this month’s Brainfit Tricks are designed to support.
The good news?
Connection doesn’t need to be big, exhausting or complicated. Small, everyday moments can have a surprisingly powerful impact on the brain. That’s exactly what this month’s Brainfit Tricks are designed to support.
Why Nutrition Matters for the Brain
Your brain is one of the most energy-demanding organs in your body.
Although it accounts for only around 2% of your body weight, it uses approximately 20% of your daily energy. Every thought, memory, decision and emotion depends on a steady supply of nutrients. Just as your body performs best when it’s well fuelled, so does your brain.
Nutrition influences:
- attention and concentration
- mood and emotional wellbeing
- memory and learning
- inflammation and oxidative stress
- energy levels and mental clarity
- the health of the gut microbiome
Scientists now know that the gut and brain are constantly communicating through what’s known as the gut-brain axis. The trillions of microbes living in your digestive system influence mood, thinking and even memory.
In other words, when you nourish your gut, you’re also helping nourish your brain. Because food doesn’t just affect how long we live – it influences how well we think, learn, remember and feel along the way.
Your brain was designed to connect. Connection is an important part of brain health.
Why Healthy Eating Can Feel So Difficult
Modern life doesn’t always make healthy eating easy. Busy schedules, conflicting nutrition advice, convenience foods and “all-or-nothing” thinking can leave us feeling confused or discouraged.
Many people believe they need to “eat perfectly” to support brain health. But perfection isn’t the goal.
Long-term brain health is built through small, sustainable habits rather than extreme changes – an extra handful of vegetables, more fibre, a little more protein with breakfast or healthy fats a few times a week. Small choices repeated consistently are what make the difference.
At the same time, research is increasingly showing that diets high in ultra-processed foods, such as sugary drinks, packaged snacks and many ready meals are associated with poorer cognitive performance, an increased risk of depression and a greater risk of cognitive decline over time. Even relatively small increases in these foods have been linked to measurable changes in attention and memory.
The good news is that every meal is an opportunity to support your brain. By choosing whole, minimally processed foods more often, you’re providing your brain with the steady supply of nutrients it needs to think clearly, learn effectively and function at its best.
Because when it comes to nourishing your brain, it’s the choices you make most often that have the greatest impact over time.
4 Brainfit Tricks to Nourish Your Brain
These four Brainfit Tricks are designed to support both your brain and your gut microbiome. You can watch a short video about each by clicking on the hyperlinks below.
Trick #21 – Eat The Rainbow
Colour your plate. Feed your brain.
The science
Brightly coloured fruits and vegetables contain antioxidants and plant compounds called polyphenols that help protect brain cells from oxidative stress and inflammation.
Different colours provide different nutrients, so variety matters.
Why it matters
Greater diversity on your plate means greater diversity for your gut microbiome — and that’s good news for your brain.
Try this
Challenge yourself to add one extra colour to your plate today. Blueberries, carrots, spinach, beetroot, tomatoes and capsicum all count.
Trick #22 – Feed Your Gut Bugs
Healthy gut. Healthy brain.
The science
Your gut and brain are in constant communication via what’s known as the gut-brain axis.
The trillions of microbes living in your digestive system influence mood, inflammation, stress responses and even cognitive function.
One of the best ways to support these microbes is through fibre-rich foods.
Why it matters
Healthy gut bacteria help produce compounds that support brain health and emotional wellbeing.
Try this
Try to include more:
- vegetables
- fruit
- legumes
- nuts
- seeds
- whole grains
Think of fibre as food for your gut bugs.
Trick # 23 – Don’t Fear Healthy Fats
Feed your brain healthy fats.
The science
Your brain is almost 60% fat and relies on healthy fats to maintain the membranes surrounding brain cells and support communication between neurons.
Omega-3 fats are particularly important for learning and memory.
Why it matters
Healthy fats help support memory, learning and overall brain performance. They may also help protect cognitive health as we age.
Try this
Include more:
- oily fish such as salmon or sardines
- walnuts
- flaxseeds and chia seeds
- Avocado
- extra virgin olive oil
Trick #24 – Make Protein Part Of Your First Meal
Protein powers your brain.
The science
Protein provides amino acids that your brain uses to manufacture neurotransmitters involved in attention, motivation and mood.
Including protein in your first meal helps provide a more stable supply of energy throughout the morning.
Why it matters
Your brain performs best when fuel arrives steadily rather than in large spikes and crashes.
Try this
Include one protein-rich food with your first meal:
- eggs
- Greek yoghurt
- nuts and seeds
- beans
- Tofu
- fish
Why These Strategies Work Together
Each of these Brainfit Tricks supports a different aspect of brain health.
- colourful foods provide antioxidants and plant nutrients
- fibre-rich foods nourish the gut microbiome
- healthy fats support brain cell communication
- protein provides the building blocks for neurotransmitters
Together, they help create the environment your brain needs to think clearly, learn efficiently and function at its best. At the same time, limiting highly processed foods where possible helps reduce some of the factors linked with inflammation, poor mood and declining cognitive performance.
And importantly, they are all small, realistic and repeatable. Because long-term brain health is built one meal, one snack and one healthy choice at a time
