Kids’ lunchboxes are being packed with too many chips, biscuits, and processed snacks, according to new research.

The study, conducted by Deakin University, involved interviews with 682 primary school students to find out what they’re eating.

Research shows that children between eight and twelve years old consume about 47% of their daily calories from ultra-processed foods, including items like chips, cookies, and sausage rolls.

“These foods contain additives such as colors, emulsifiers, flavors, and thickeners,” explained Dr. Carley Grimes of the Institute for Physical Activity & Nutrition.

“It’s setting children up for poor eating habits.”

This study raises concerns regarding the potential long-term health effects, as there is a link between high intake of ultra-processed foods and an elevated Body Mass Index (BMI) in children as young as ten.

“If it persists later into life – that sets them up for a range of chronic disease risk,” Grimes said.

Cost and convenience were identified as significant factors behind the glut of processed food. 

The study looked at what kids ate over a full 24 hours, so while what’s in the lunchbox is key on school days, experts say there’s plenty of scope to also pack extra good stuff into breakfast and dinner.

Making homemade options, freezer stashes, and buying in-season are other tips to help parents get the balance right.
