Could cutting ultra-processed foods prevent diabetes? new study investigates

NCT ID NCT05358171

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at how eating a lot of ultra-processed foods (like packaged snacks and sugary drinks) affects blood sugar control and gut bacteria in adults aged 45 to 65. Twenty participants followed either a high-UPF or no-UPF diet for six weeks. The goal was to see if these foods impair insulin sensitivity and glucose control, which could lead to type 2 diabetes. This is a small, early-stage trial meant to guide future, larger studies.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

controlled diets (high ultra-processed food vs. no ultra-processed food)

What this could lead to

If it works, this could point toward dietary guidelines to reduce type 2 diabetes risk in middle-aged adults.

What could go wrong

This is a very small, early proof-of-concept study with only 20 participants. Results may not apply to the general population, and the diets are tightly controlled, so real-world effects could differ.
