In the hustle and bustle of modern life, in which deadlines loom and exams dominate, it’s too easy to let healthy eating habits slide. Mornings often begin with a rush, leading to skipped breakfasts or leading us to eat processed snacks or sugary treats. Lunch becomes a quick sandwich or takeaway option, while the afternoon energy dip sends us reaching for caffeine or a quick sugar fix.
What we use to fuel our bodies has a direct impact on brain function, energy, and overall wellbeing, reinforcing the importance of nutritional awareness. Regularly skipping meals or relying on highly processed foods and sugary snacks throws this balance off. The result is often brain fog, low energy, irritability, and a decline in cognitive performance.
A diet rich in whole foods, lean proteins, healthy fats, and complex carbohydrates provides the sustained energy and essential nutrients needed for sustained concentration, improved memory, and enhanced problem-solving skills.
According to a report by the Commonwealth Scientific and Industrial Research Organisation (CSIRO) titled “Fresh fruit down, junk food up: our modelling suggests Australian diets will get worse by 2030”, current trends indicate that Australians are likely to consume significantly more junk food and less fruit by 2030. If these patterns continue, junk food intake could rise by approximately 18%.
At the same time, fruit consumption is expected to fall by almost 10%, pushing Australia even further away from national healthy eating targets. As per the report, fewer than 5% of Australians currently meet the full recommendations of the Australian Dietary Guidelines, including the suggested daily serves of fruit and vegetables.
Why Healthy Eating Matters for Focus
Our brains are energy-hungry organs, they require a constant supply of nutrients to perform well. When we eat foods high in added sugars and refined carbohydrates, blood sugar levels spike quickly and then crashes. This creates waves of energy highs and lows, leaving us feeling groggy, distracted, or simply unable to concentrate on tasks for long periods.
On the contrary, nutrient-dense foods particularly those rich in fibre, protein, healthy fats, vitamins, and minerals help stabilise blood glucose, support slow energy release, and fuel the brain more efficiently.
In schools, students often consume up to one-third of their energy intake during school hours alone. This makes the nutritional quality of snacks and lunches at school especially important for building lifelong healthy eating habits.
In workplaces, employees may spend more than half of their weekdays eating breakfast, snacks and lunch at work, meaning the workplace environment plays a huge role in shaping daily eating patterns, staff wellbeing, and overall wellbeing, highlighting the need for healthy workplaces.
Strategic Snacking for Sustained Focus
Snacks often get a bad reputation, but when chosen wisely, they can actually play an important role in keeping energy levels steady and reducing the urge to overeat at main meals. The crucial distinction lies in the type of snacks we choose. Rather than reaching for chips or candy bars, look out for nutrient-dense options that deliver lasting energy and function as healthy snacks. Here are some great choices to consider:
Mixed nuts and seeds: A nutrient powerhouse packed with healthy fats, protein, and fibre. Almonds, walnuts, chia seeds, and pumpkin seeds are particularly beneficial for brain health and sustained energy.
Low-sugar trail mix: Making your own trail mix allows you to control the ingredients and avoid excess sugar. You can make your own blend using nuts, seeds, a small amount of dried fruit, and a few dark chocolate chips for a balanced snack that offers both energy and satisfaction.
Dark chocolate: Can be enjoyed in moderation, dark chocolate (70% cocoa or higher) is rich in antioxidants and may help improve blood flow to the brain. This can support mood, mental clarity, and concentration while still satisfying sweet cravings.
Fruits: Apples, bananas, oranges, and berries are packed with vitamins and antioxidants. They offer a quick yet healthy energy boost and are easy to include in lunchboxes or as an on-the-go snack.
Whole-grain crackers: Whole-grain crackers are a good source of complex carbohydrates. Pairing them with protein-rich or healthy fat options like cheese, avocado, or hummus helps slow digestion and provides longer-lasting energy.
Herbal teas: Chamomile, peppermint, or green tea can offer a calming or energising effect without the jitters of excessive caffeine. Green tea, in particular, contains L-theanine, an amino acid that can improve focus and relaxation.
Nut Bar: Nut bars are a convenient snack option, especially on busy days. They provide a combination of protein, healthy fats, and antioxidants, making them ideal for sustained energy when time is limited.
Muesli Bar: Choose varieties made with whole grains, nuts, fruits, and seeds, and minimal added sugar for a more balanced option.
Popcorn: Air-popped popcorn, lightly seasoned, is a whole-grain snack that’s high in fibre and low in calories. It can be a satisfying alternative to chips when you’re craving something crunchy.
Flavoured Sparkling Water: Flavoured sparkling water is a refreshing, sugar-free alternative to soft drinks, helping you stay hydrated without unnecessary calories. Options like Yaru Sparkling Water are naturally rich in minerals, certified carbon neutral, and approved by the Biological Farmers of Australia. With crisp flavours and no added sugar, they’re an excellent choice for maintaining hydration, supporting focus, and satisfying cravings for something fizzy throughout the day.
Energy Drink: When choosing energy drinks, opt for low-sugar or naturally caffeinated options. Consuming them in moderation can provide a short-term boost in alertness and focus without the sharp spikes and crashes often caused by high sugar and excessive caffeine.
Cereals: Cereals can make a quick and nutritious snack when chosen carefully. Look for varieties high in fibre and low in added sugar, and pair them with milk or yoghurt to add protein and create a more balanced, satisfying option.
How to Create Supportive Environments
While individual choices matter, lasting improvements in healthy eating habits require strong systemic support through targeted wellbeing initiatives. Workplaces and schools are in a unique position to influence daily habits, making healthier options easier, more accessible, and more appealing.
By creating environments that encourage good nutrition, they can boost energy, focus, and overall wellbeing.
At Work:
1. Vending Machines: Businesses can prioritise stocking vending machines with the healthy snacks like trail mix, mixed nuts & seeds, muesli bars, popcorn, and whole-grain crackers, rather than sugary drinks and processed foods.
2. Fruits initiatives: Providing free fresh fruit at certain times of the week can encourage employees to make healthier choices and support staff wellbeing.
3. Educational Workshops: Short, engaging workshops on nutrition, meal prepping, and healthy snack ideas can build nutrition awareness and empower employees with practical skills.
4. Dedicated Break Spaces: Creating inviting break rooms with access to refrigerators, sandwich press, air fryer, and microwaves encourages employees to bring healthy lunches and snacks from home.
5. Promoting Hydration: Ensuring readily available filtered water stations and encouraging water intake throughout the day.
6. Flexible Work Schedules: Where possible, allowing for slightly longer lunch breaks can encourage employees to step away from their desks and enjoy a proper, mindful meal, reinforcing healthy workplaces.

At School:
1. Curriculum Integration: Nutrition education should be an integral part of the school curriculum from an early age, strengthening nutrition awareness. Teaching children about food groups, healthy choices, and the impact of food on their bodies and minds.
2. Healthy Canteens and Tuckshops: Schools should implement strict policies regarding the food sold in canteens, prioritising fresh, whole foods and limiting access to highly processed, sugary, and fatty options. Many Australian schools already follow the National Healthy School Canteens Guidelines, which use a simple “traffic light” system to guide food choices.
3. “Crunch & Sip” Programs: Popular in Australian primary schools, particularly in WA, NSW, and QLD, these dedicated times allow students to eat fruit or vegetables and drink water in the classroom. This simple routine helps build healthy eating habits while supporting focus and concentration during learning time.
4. Parental Engagement: Providing resources and workshops for parents on healthy lunchbox ideas and encouraging nutritious eating at home.
5. Gardening Programs: School gardens can be an excellent way to teach children about where food comes from, healthy eating, and even encourage them to try new fruits and vegetables.
6. Role Modelling: Teachers and school staff who model healthy eating habits can have a powerful influence on students.
In busy work and school environments, where sustained focus and energy are essential, healthy eating plays a vital role in daily performance. Encouraging smart snacking choices such as mixed nuts, fresh fruit, and whole-grain crackers helps provide steady energy and supports better concentration throughout the day. When these habits are reinforced by supportive environments through wellbeing initiatives, individuals are more likely to make healthier choices.
Together, these efforts create healthier habits that lead to improved focus, stronger performance, and more positive daily outcomes.
