Metabolomics-Driven Insights Into Ultra-Processed Foods
Metabolomics-Driven Insights Into Ultra-Processed Foods: Identifying High-Risk UPF Subtypes for T2D Prevention
The goal of this dietary intervention study in generally healthy adults is to develop new ways to use blood samples to measure the common types of highly processed foods and beverages that people eat on a regular basis. The main aims to answer are:
What small molecules are elevated in blood after eating different types of highly processed foods and beverages consistently for 1 week?
Researchers will compare 3 different test diets with 1 control diet that does not have any highly processed foods in the same individuals to see which circulating blood markers change.
Participants will:
- Complete 3 diet phases, each 2 weeks long
- Receive a meal plan and study foods and beverages to follow for each 2-week phase
- Come to the clinic every week for blood draws, urine samples, and stool collection kits

Within-person metabolomic response during each UPF test diet, compared to the paired non-UPF control diet.
Časové okno: Day 0, Day 7, and Day 14 of each dietary intervention period
|
The primary outcome for this study is within-person metabolomic response during each UPF test diet, compared to the paired non-UPF control diet.
Metabolomic responses will be quantified from metabolite concentrations (e.g., relative abundance) measured in fasting plasma samples collected at day 0, day 7, and day 14 in each diet phase.
