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

Detaljert beskrivelse

UPFs, characterized by industrial processing and the use of cosmetic additives for enhanced palatability and extended shelf-life, account for approximately 58% of caloric intake in the U.S. population. Although some UPF subtypes have been implicated in increasing risk of T2D and other chronic diseases, others may be relatively inert or even beneficial, underscoring the need for discerning their distinct health effects. This trial is a controlled crossover feeding trial design with target enrollment of 40 generally healthy adults. Partcipants complete 3 2-week isocaloric dietary intervention phases, with 1 week of a control diet of non-ultraprocessed foods and beverages, and 1 week of a UPF-based test diet. The 3 UPF test diets each feature a menu consisting of a UPF subtype: starchy and refined grains, meats and fish, or dairy-based products. Foods and beverages are provided during the diet phases, and participants will attend weekly clinic visits for in-person assessments and biospecimen collections. We will obtain metabolomic profiling of the fasting plasma samples and conduct data analyses to isolate novel biomarkers that reflect the intake of the UPFs, such as industrial additives. These objective signatures of UPF intake will support subsequent research investigating the long-term health outcomes relate d to UPF consumption. Identifying metabolomic signatures of UPF subtypes will enhance the understanding of the biological mechanisms linking UPFs to T2D and other chronic disease risks.

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.
