Diabetes is no longer just an adult concern—children are increasingly being diagnosed with both Type 1 and Type 2 diabetes.
The World Health Organisation states that while Type 1 diabetes is largely genetic and cannot be prevented, Type 2 diabetes is often linked to lifestyle factors such as poor diet and lack of physical activity.
With childhood obesity on the rise, experts warn that more young people are at risk of developing the condition. The good news is that early intervention and healthier habits can make a world of difference.
Encouraging a healthy diet
One of the biggest culprits behind childhood diabetes is excessive sugar and processed foods. According to the American Diabetes Association, sugary drinks like sodas and fruit juices, along with refined carbs like white bread and chips, contribute to insulin resistance.
The health publication mentions that the key is to swap these for whole foods: fibre-rich fruits, vegetables, whole grains, and lean proteins. It is stated that not only do these foods help regulate blood sugar levels, but they also keep kids feeling fuller for longer, reducing unnecessary snacking.
Registered dietitian Dr Tamlyn Maree suggests making small but consistent changes, such as replacing white rice with brown rice and introducing fun, colourful veggie options to meals. “Children are more likely to enjoy healthy food when they feel involved in the process—let them pick out fresh produce or help prepare meals,” she says.
The role of physical activity
Regular exercise is another powerful tool in preventing and managing diabetes. The Centers for Disease Control and Prevention recommends at least 60 minutes of physical activity daily for children. This doesn’t mean forcing them into structured workouts—simple activities like playing soccer, dancing, cycling, or even jumping on a trampoline can be just as effective, adds the publication.
Dr Kabelo Mokoena, a paediatric endocrinologist at a Johannesburg children’s hospital, emphasises that movement is crucial for insulin sensitivity. “Exercise helps the body use glucose efficiently, which is essential for preventing Type 2 diabetes,” he explains.
Limiting screen time and promoting sleep
Excessive screen time has been linked to sedentary lifestyles, poor sleep, and unhealthy eating habits—factors that increase the risk of diabetes. The World Health Organization advises limiting recreational screen time for children to under two hours per day. Additionally, ensuring kids get enough sleep (8-10 hours per night) can improve metabolism and reduce cravings for sugary foods.
Regular check-ups and awareness
The South African Journal of Clinical Nutrition mentions that health screenings can catch early warning signs of diabetes, such as unexplained weight loss, increased thirst, or frequent urination. If there’s a family history of diabetes, regular doctor visits are even more important.
While childhood diabetes is a growing concern, it’s not an inevitable fate. With a balanced diet, active lifestyle, and mindful habits, parents can empower their children to lead healthier, diabetes-free lives.
