How does food affect brain development?

Nutrition plays a foundational role in shaping a child’s cognitive and emotional development. The brain grows rapidly in the early years and relies heavily on specific nutrients to function well. Foods rich in omega-3 fatty acids, such as oily fish and seeds, support memory and focus. Iron helps with energy and alertness, while vitamins B and D contribute to emotional regulation and neurological health. When children eat a variety of whole foods including colourful vegetables, fruits, whole grains, proteins, and healthy fats, they are more likely to be calm, attentive, and resilient.
On the other hand, frequent intake of processed foods, refined sugars, and artificial additives can lead to mood swings, poor sleep, and reduced concentration. These effects can impact not only behaviour but also how the brain stores and retrieves information. A child who eats poorly may struggle with learning, while one who is nourished thoughtfully shows increased curiosity, better emotional balance, and improved cognitive stamina. Supporting healthy eating habits early on lays the foundation for academic achievement, emotional wellbeing, and lifelong health. Mealtimes become opportunities for connection, conversation, and long-term investment in a child’s growth.
