Ultra-Processed Foods Linked to Early Blood Sugar Risks in Young Adults

A new study from the Keck School of Medicine of USC shows that frequent consumption of ultra-processed foods (UPFs) significantly raises the likelihood of early blood sugar problems in young adults. UPFs—such as fast food, packaged snacks, sweetened beverages and ready-to-eat meals—make up more than half of daily calorie intake for many Americans. Although their connection to type 2 diabetes is well established in adults, little was known about their effects in younger populations.

Researchers followed 85 individuals aged 17–22 for four years and found that even small increases in UPF intake elevated the risk of prediabetes and insulin resistance. A 10% rise in UPF consumption was associated with a 64% higher chance of developing prediabetes. The findings highlight early adulthood as a crucial period for building healthier eating habits. Cutting back on heavily processed foods and choosing whole, nutrient-rich options may help protect long-term metabolic health.
