A cascade of problems from eating too much, too often
Ultra-processed foods high in refined carbohydrates force the pancreas to overproduce insulin, triggering insulin resistance and cascading metabolic problems. Children increasingly face hormonal and metabolic disorders linked to poor dietary patterns and sugar-laden products marketed to youth, compounding long-term health risks.

Endocrinologists warn that frequent consumption of ultra-processed foods disrupts hormone production and increases risk of metabolic diseases, diabetes, and hormonal disorders, particularly in children and adolescents.
Walk into any supermarket in Latin America and you'll find the shelves stacked with the same products that line stores everywhere else: brightly packaged snacks, sugary drinks, ready-to-eat meals. They're convenient. They taste good. Millions of children eat them every day without a second thought. But endocrinologist Inoelva Espinal has spent her career watching what happens inside the body when these foods become routine, and she's increasingly alarmed.
The problem isn't simply weight gain, though that's part of it. The real damage happens at the hormonal level. Hormones are chemical messengers that govern everything the body does—growth, metabolism, reproduction, appetite, sleep, stress response. When the diet floods the system with refined carbohydrates and added sugars, the pancreas responds by pumping out more and more insulin to manage the blood sugar spike. This isn't a one-time event. It's a pattern. Day after day, meal after meal, the pancreas works overtime. "If I'm eating a lot, I'm going to produce more, and that's going to bring me a cascade of problems," Espinal explained during an appearance on the morning program Buenos Días RD. Over time, this chronic overproduction can trigger insulin resistance—a condition where the body's cells stop responding properly to insulin signals. Once that happens, the metabolic dominoes start to fall: type 2 diabetes, high blood pressure, elevated cholesterol, and a range of other metabolic disorders follow.
What worries Espinal most is where this is happening. Children and adolescents are increasingly showing up in clinics with hormonal and metabolic problems that used to be rare in young people. The Pan American Health Organization has documented sustained growth in childhood overweight and obesity across Latin America, a trend directly tied to the consumption of ultra-processed foods and sugary beverages. Many of these products are specifically marketed to kids—packed with sugar, artificial colors, flavorings, and additives designed to be irresistible. "Today, sadly, hormonal disorders in children are produced by poor nutrition and parents' lack of knowledge," Espinal said. The research backs this up. Studies in international scientific journals have linked these products to early metabolic changes, weight gain, and increased risk of chronic disease in adulthood.
But diet isn't the only culprit. Espinal also pointed to chronic stress, increasingly common in modern life, as a significant hormonal disruptor. When the body faces a threat—real or perceived—it releases cortisol and adrenaline to mount a response. The problem is that the body doesn't distinguish between a predator chasing you and financial worry or social pressure. When stress persists for weeks or months, cortisol levels stay elevated, and that takes a toll: weight gain, sleep disruption, anxiety, fatigue, and metabolic dysfunction.
The solution, according to Espinal, requires returning to basics. Prioritize fresh, whole foods over processed products. Move the body regularly—the World Health Organization recommends at least 150 minutes of moderate activity per week for adults and one hour daily for children and adolescents. "You have to exercise your whole life," she emphasized. These aren't revolutionary ideas, but they're increasingly countercultural in a food environment designed to make convenience and ultra-processed products the default. The scientific consensus is clear: what we eat doesn't just affect our waistlines. It rewires the hormonal systems that control nearly every function of the body. For children growing up in this environment, the stakes are particularly high. The habits formed now, and the metabolic damage done now, will shape their health for decades to come.

La Conversación del Hearth Otra perspectiva de la historia
Why does the pancreas overreact so dramatically to refined carbohydrates? Is it a design flaw, or is it just doing what it's supposed to do?
It's doing exactly what it evolved to do—respond to a glucose spike by producing insulin to bring blood sugar back down. The problem is frequency and magnitude. Our ancestors might have experienced that spike once in a while. Now it's happening three times a day, every day, for years. The pancreas gets exhausted and the system breaks down.
So when you say hormonal disorders in children are from "poor nutrition and parents' lack of knowledge," are you blaming parents, or the food system that makes poor choices so easy?
Both, honestly. Parents are navigating a system designed to make ultra-processed food the cheapest, most convenient option. But knowledge matters too. If a parent understands what's happening inside their child's body, they might fight harder against that system.
You mentioned stress and cortisol. How much of the metabolic crisis in children is actually food, and how much is the stress of modern life?
They're intertwined. A stressed child reaches for comfort food. That food destabilizes their blood sugar, which makes them more anxious. It's a feedback loop. You can't really separate them.
What does "exercise your whole life" actually mean for a busy parent trying to keep a family fed?
It means movement doesn't have to be a gym membership. It's walking instead of driving. Playing outside instead of screens. Dancing in the kitchen. The barrier isn't knowledge—it's that we've built environments where stillness is the default.
If a child has already developed insulin resistance, is it reversible?
Yes, but it takes time and consistency. The body can heal, but only if the pattern changes fundamentally. That's why prevention in childhood is so critical. It's much easier to never develop the problem than to reverse it.
