I’m a Dietitian: Science-Backed Food Hacks to Set Your Child Up for Success in 2025
Dietitian shares science-backed foods that fight winter illness and enhance learning
With winter illnesses threatening to disrupt the new school term and flu cases among school children currently twice the national average, parents are seeking ways to keep children healthy and focused. Now, a dietitian reveals that specific food choices – and how they’re introduced – can transform both eating habits and learning potential.
Here, we have worked with Explore Learning and Jennifer Pallian, BSc, RD, a Registered Dietitian, and mother of three school-age children, to share evidence-based nutrition guidance that supports learning during the challenging winter months.
1. The lunchbox that prevents afternoon fatigue
The post-lunch energy crash can significantly impact learning, but strategic food choices can help maintain focus throughout the school day. Combining the right foods at lunchtime creates sustained energy release, preventing the mid-afternoon slump.
“To prevent afternoon fatigue, children can benefit from lunching on protein and complex carbs like whole grains, brown rice, and veggies,” says Pallian. “These stabilise blood sugar, providing steady energy, improving focus, and reducing the risk of energy dips from refined sugars.”
2. How to win the picky eater dinner time battle
Parents struggling with fussy eaters can take heart from research revealing the key to acceptance of new foods. Making mealtimes positive and engaging is crucial, with consistency being key to success.
“It can take 8-10 exposures for a child to accept a new taste,” explains Pallian. “Keeping fruits and vegetables visible and accessible at home can increase a child’s willingness to try them. Engaging kids in food prep, taste-testing, or gardening introduces them to various foods in a hands-on, enjoyable way.” Family meals also provide a supportive setting where children can observe positive eating behaviours and develop healthy relationships with food.
3. Foods that fight winter illness
With cold and flu season approaching, certain foods can help reduce school absences. The right combination of nutrients works together to strengthen children’s natural defences and support respiratory health.
“Zinc, found in meats, shellfish, legumes, and seeds, can reduce cold frequency, severity, and missed school days,” notes Pallian. She explains that adding probiotics through yoghurt, kefir, and fermented foods also helps reduce respiratory infections and symptoms.
4. Daily foods that can transform learning
Research shows specific nutrients can enhance academic performance, with certain foods having a direct impact on concentration and learning ability. Regularly eating these key nutrients supports brain development and cognitive function throughout the school year.
“Fish, especially oily varieties, provide essential omega-3s like DHA and EPA for cognitive development,” explains Pallian. “About 8 grams per day (or 2-3 servings per week) is beneficial, with moderate intake linked to better sleep, academic performance, and focus in school subjects like math and language.”
5. Breakfast for success
Starting the day with the right combination of nutrients can significantly impact a child’s learning potential. Research shows that carefully balanced breakfast choices support sustained concentration throughout the morning.
“A balanced breakfast with a mix of complex carbs, protein, and healthy fats is key to keeping energy levels steady,” explains Pallian. “Oatmeal with nuts, eggs with whole-grain toast, or yogurt with fruit and seeds all work well for maintaining steady energy and concentration.”
6. Food choices now set kids up for future success
Establishing good nutrition habits early on has lasting benefits. “Children who adopt healthy eating habits are less likely to struggle with obesity as adults,” Pallian reveals. “Establishing healthy eating patterns in childhood can prevent childhood obesity, lowering the risk of long-term health issues like diabetes, cardiovascular disease, and respiratory problems.”
Charlotte Gater, Head of Education at Explore Learning adds: “In our tuition centres, we see thousands of children every week, and energy levels play a huge role in how well they engage with learning. Understanding how nutrition can support academic success is vital information for parents and carers. When children are properly nourished, they are more focused and ready to learn which ultimately fuels progress. Simple changes to daily food choices can make a real difference in helping children stay energised and ready to learn.”
