CAN YOU EAT YOUR WAY TO BETTER SCHOOL GRADES?

As kids head back to school next week, our news feeds will be inundated with tips for creating nutritious, Insta-perfect lunchboxes.

Keeping up energy and fuelling the brain with a good quality recess and lunch is essential, however, when it comes to better academic performance, what children eat before they head off to school really matters.

Research shows breakfast has the greatest dietary influence on school grades, with a significant body of research supporting the role of breakfast and its impact on specific measures of brain function, cognition and academic achievement.1-6

Here’s five reasons why breakfast before school matters…

Number one dietary factor

A systematic review by the University of Newcastle investigated the effects of dietary intake and behaviours on school-aged children’s academic achievement.1  

It identified regularly eating breakfast as the most common dietary factor associated with better school grades.1 This was followed by lower intakes of energy-dense, nutrient-poor foods and better quality diets overall.1  

Boosts literacy and numeracy

There is more than 50 years of science supporting an association between breakfast and cognition.5

Eating breakfast improves brain function helping children perform better at school in problem solving, creative and mathematical tasks.1-6

An Australian study of 824 children, in grades 3-7, indicated that a good quality breakfast was linked to higher literacy scores, even after adjusting for socioeconomic status and parental education levels.2

Quality matters

The benefits of eating breakfast are related to the nutritional quality of the breakfast and the fact that breakfast eaters have more nutritious diets overall.1,2,5

Providing a good breakfast is a concern for parents with two thirds worried their children don’t eat enough before they go to primary school.7

So what is a good quality breakfast? Some nutrition scientists recommend a good quality breakfast as including at least three of the five food groups and providing about a fifth of the energy and nutrients. 8 This could be breakfast cereal, fruit and milk or yogurt, or it might be a slice of toast with baked beans and a glass of milk.

A recent analysis of ABS Australian Health survey data revealed children that started their day with breakfast cereal had the highest intakes of dietary fibre and nutrients including calcium and iron – key nutrients where Australian children are falling short.9 In fact compared to children that ate other foods for breakfast, cereal eaters had 32% more iron, 30% more riboflavin, 23% more calcium, and 9% less salt in their daily diets.9 It also found the nutritional benefits were consistent, regardless of the total sugars* content of the breakfast cereal eaten.9

Research versus class room reality

The benefits of eating breakfast are seen in the classroom on a daily basis, by both teachers and children.

Australian teachers estimate that the average student loses more than two hours a day of learning time when they come to school hungry.10

While children who admit to skipping breakfast are twice as likely to say they get “hangry” at school, compared to children that never skipped breakfast (27% vs 14%).11 They say as a result of their hunger they feel grumpy or get annoyed at friends. 11  They’re also more likely to forget to do school work and feel tired.11

 Eating breakfast helps to stabilise blood sugar levels, which regulates appetite and energy levels. Children who eat breakfast are less likely to be hungry and overeat during the rest of the day.12,13

More than grades

The benefits of regular breakfast habit extend far beyond better grades. An Australian study of adolescents revealed eating breakfast with at least three core food groups was associated with long-term better mental health. 4  

There is also significant evidence associating a regular breakfast habit and regular breakfast cereal consumption among children with healthier weights, more nutritious diets and higher nutrient intakes. 14,15
