We know that fuelling children with the appropriate foods helps support their growth and development. But there is a growing body of research showing that what children eat can affect not only their physical health but also their mood, mental health and learning.
The research suggests that eating a healthy and nutritious diet can improve mental health¹, enhance cognitive skills like concentration and memory²‚³ and improve academic performance⁴.
Children should be eating plenty of nutritious, minimally processed foods from the five food groups:
- vegetables and legumes/beans
- grains (cereal foods)
- lean meat and poultry, fish, eggs, tofu, nuts and seeds, and legumes/beans
- milk, yoghurt, cheese and/or their alternatives.
Consuming too many nutritionally-poor foods and drinks that are high in added fats, sugars and salt, such as lollies, chips and fried foods has been connected to emotional and behavioural problems in children and adolescents⁵. In fact, young people that have the unhealthiest diets are nearly 80% more likely to have depression than those with the healthiest diets¹.
Why are schools an important place to make changes?
Schools can play a key role in influencing healthy eating habits, as students can consume on average 37% of their energy intake for the day during school hours alone!6
A New South Wales survey found that up to 72% of primary school students purchase foods and drinks from the canteen at least once a week7. Also, in Victoria, while around three-quarters (77%) of children meet the guidelines for recommended daily serves of fruit, only one in 25 (4%) meet the guidelines for recommended daily serves of vegetables8; and discretionary foods account for nearly 40 per cent of energy intake for Victorian children9.
It’s never too late to encourage healthier eating habits – childhood and adolescence is a key time to build lifelong habits and learn how to enjoy healthy eating.
Get started today
You can start to improve students’ learning outcomes and mental wellbeing by promoting healthy eating throughout your school environment.
Some ideas to get you started:
"When kids eat a healthy diet with a wide variety of fruit and vegetables in that diet, they actually perform better in the classroom.
They're going to have better stamina with their work, and at the end of the day it means we'll get better learning results which will impact on them in the long term."
