‘Stop blaming sugar’: Doctor reveals what really causes diabetes, says it’s not the dessert plate

If you are a parent, you have probably said it to your kids, “No more sweets or you’ll get diabetes!” It is practically a universal warning in households but here’s the twist: sugar does not cause diabetes the way we imagine it. In fact, if diabetes had a villain origin story, sweets would barely make it into the supporting cast.

In an interview with the Times of India, Dr Amit Gupta, Senior Consultant - Paediatrician and Neonatologist at Motherhood Hospitals in Noida, broke down what’s really going on behind the scenes and spoiler alert — the truth has much more to do with genetics, lifestyle, screen time and how the body handles insulin than with the occasional cupcake. Diabetes cases are spiking not because kids eat too many chocolates but because they move less, snack more and often inherit risk factors they can’t see.




Here’s the important part: early awareness can completely change the story. So before you toss the dessert plate or panic about sugar, let’s debunk the myths, understand the science and learn how to keep our kids thriving in a world full of screens, snacks and school pressure.

Dr Gupta shared, “Diabetes is a common occurrence not only in adults but even children. Many children are struggling with it and are suffer in silence. When parents hear the word “diabetes”, the first thing that comes to mind is sugar but in reality, childhood diabetes is much more complex. It’s not just about eating sweets; it’s about how the body processes insulin, the hormone that helps control blood sugar levels. The spike in cases of diabetes in children is due to sedentary lifestyles and unhealthy eating habits.”

He added, “Kids today spend more time indoors on gadgets, move less, and often eat high-calorie, low-nutrient foods. Combined with genetic predisposition, this increases the risk of insulin resistance when the body doesn’t use insulin effectively. So, parents should understand the warning signs of diabetes in children so that it can be prevented or managed early.”

He dispelled the following myths linked to sugar and diabetes -

Myth 1: Eating sugar causes diabetes

Fact: Many parents believe that just eating sweets alone doesn’t cause diabetes. Type 1 diabetes happens when the immune system mistakenly attacks the insulin-producing cells in the pancreas. It has nothing to do with sugar intake. Even other factors, such as genetics and family history, can also cause diabetes.

A classic 2003 study published in the journal Diabetes found that children with a family history of diabetes exhibit significantly higher fasting insulin levels and insulin resistance than those without familial risk.

Myth 2: Only adults get diabetes

Fact: Type 2 diabetes, once seen only in adults, is now rising among children due to poor diet, lack of exercise and obesity. Long hours of screen time, processed food, and sugary drinks add to the risk.

A two-year longitudinal study of 630 children in JAMA Pediatrics found that increases in body fat (adiposity) strongly predicted declining insulin sensitivity and greater insulin secretion, even in kids.

Another 2010 JAMA Pediatrics study revealed that adolescents who spent two or more weekday hours on screen time had elevated insulin resistance, making sedentary habits a clear risk factor for metabolic problems.

Myth 3: Diabetes means giving up all fun foods

Fact: Children with diabetes will be required to eat in moderation. However, the parents should watch the quantity. The key is moderation and choosing healthy meals rich in fiber, whole grains, fruits, and vegetables.

Guidance for parents: A balanced plan with vital tips for children

Dr Gupta suggested -

• Limit screen time: Encourage outdoor play or physical activity instead of electronics. Reducing daily screen usage can help lower metabolic risk.
• Promote regular exercise: Aim for at least 60 minutes of activity daily — from sports to simple play.
• Focus on diet quality: Prioritise whole foods like vegetables, whole grains, lean proteins and water instead of sugary drinks.
• Monitor health: If there is a family history of diabetes, consider regular blood sugar screenings for your child and watch for symptoms like excessive thirst or unexplained weight loss.
• Educate your child: Teach them about diabetes in age-appropriate ways, emphasizing that it’s not just about sugar but about how the body uses insulin.

Bottom line

Diabetes is not a simple “sugar problem.” It is a multifaceted metabolic challenge influenced by genes, lifestyle and physiology. By understanding this complexity and taking steps early, parents can help their children stay healthy, active and diabetes-aware, not diabetes-fearful.
