Ultra Processed Foods Linked to Prediabetes in Young Adults

A new study published in Nutrition and Metabolism reports that rising intake of ultra-processed foods may be quietly disrupting glucose control in young adults who already have a history of being overweight or obese. The findings highlight early metabolic changes that could increase the risk of developing type 2 diabetes sooner than expected(1^✔ ✔Trusted Source

Prediabetes Risk From Rising Ultra-Processed Food Intake

In this study of 85 young adults who were followed for about four years, participants who increased their intake of ultra-processed foods by 10 percent showed 51 percent higher odds of prediabetes. They also had 158 percent higher odds of impaired glucose tolerance, a key warning sign of worsening metabolic health. Higher intake at the start of the study was linked to lower insulin sensitivity at follow-up, suggesting that glucose control weakens over time when ultra-processed foods make up a larger share of the diet.

Rising Ultra-Processed Food Intake Among Youth

Many participants increased their consumption of ultra-processed foods as they moved from adolescence into their early twenties. Researchers observed that diets became more convenient and more processed compared to the earlier years of the study. This rise in intake mattered because even a relatively small increase was tied to measurable signs of metabolic strain. The study highlights how early adulthood, a period often marked by busy schedules and irregular eating habits, can become a vulnerable window for developing insulin resistance.

Glucose Control and Insulin Sensitivity Changes

The research team found that those who ate more ultra-processed foods at baseline had higher insulin levels during glucose testing several years later. These patterns suggest that the body needs more insulin to manage the same amount of sugar, which may indicate early insulin resistance. Although body weight and body fat changes were not strongly linked to ultra-processed food intake in this study, the shifts in glucose markers were clear and consistent. This means that metabolic changes may begin even before any major change in weight is visible.

Health Insight for Young Adults

The study offers an important reminder that what people eat in their late teens and early twenties can shape their metabolic health for years to come. Even when weight remains stable, a diet high in ultra-processed foods can affect how the body handles glucose. Small changes in food choices may help protect long-term health, especially for those already at risk of developing glucose-related conditions. Your body deserves care today, not someday in the future. Start choosing foods that nourish you and protect your health.
