Insulin resistance is increasingly being identified in children and adolescents — a shift that has raised concern among healthcare professionals. While it has traditionally been associated with adults, changes in modern diets and eating patterns mean it is now appearing earlier in life.
One of the most significant contributors is hidden sugar in everyday foods.
Hidden sugars in modern diets
Many foods commonly eaten by children contain far more added sugar than most people realise. Breakfast cereals, flavoured yoghurts, fruit juices, sauces, snack bars, and processed convenience foods often include multiple forms of sugar listed under unfamiliar names.
When sugar is consumed frequently throughout the day, the body must repeatedly release insulin to regulate blood glucose levels. Over time, cells may become less responsive to insulin, forcing the body to produce more of it — a process known as insulin resistance.
This isn’t about occasional treats. It’s about regular exposure to foods that appear harmless but quietly place strain on a child’s developing metabolic system.
Modern food environments and children’s health
Today’s food environment prioritises speed, shelf life, and palatability. For busy families, convenience foods are often the most accessible option. The challenge is that long-term reliance on these foods can affect children’s metabolic health, even when portion sizes seem reasonable.
Awareness — rather than blame — is essential.
Signs of insulin resistance in children
Insulin resistance can develop gradually, and early signs are not always obvious. Some indicators parents may notice include:
- Persistent fatigue or low energy
- Increased hunger or frequent cravings for sugary foods
- Unexplained weight gain
- A family history of diabetes or metabolic conditions
- Darkened patches of skin, especially around the neck, underarms, or elbows
These skin changes, called acanthosis nigricans, are often mistaken for dirt, sun exposure, or irritation. While not diagnostic on their own, they can be a visible sign that insulin levels may be elevated.
A grounded, supportive approach
As healthcare professionals — and as parents — we understand how unsettling it can be when health concerns involve children. Conversations about insulin resistance should be approached with clarity, compassion, and practical guidance.
The reassuring reality is that insulin resistance is often modifiable, particularly when identified early. Small, sustainable changes to nutrition, movement, and daily routines can support healthier outcomes over time.
If you have concerns about your child’s health, a trusted healthcare professional can help guide next steps. Your pharmacist can assist with understanding medications, supplements, and the questions worth asking as part of a broader care plan.
