Blood markers may expose hidden dangers of Ultra-Processed foods

NCT ID NCT07717970

First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time

Summary

This study looks at how different types of ultra-processed foods affect small molecules in the blood. Healthy adults will eat three different highly processed diets and one unprocessed diet, each for two weeks. Researchers will compare blood samples to find markers that could help identify which processed foods are most linked to type 2 diabetes risk. The goal is to develop a blood test that guides healthier food choices.

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: non-UPF control, starchy/refined grain UPF diet, and meat/fish/bread UPF diet
What this could lead to
If successful, this could help identify which types of ultra-processed foods are most harmful, leading to better dietary guidelines for preventing type 2 diabetes.
What could go wrong
This is a small, early-stage study with only 40 participants, so results may not apply to everyone. It identifies markers but does not directly test whether changing diet prevents diabetes.
