What this trial studies

This study aims to evaluate the impact of returning personalized diet data on dietary habits among participants. Using a biomarker-based assessment method, participants will provide stool samples to assess their diet and receive feedback on their dietary patterns. The study will involve infants, children, and adults, with a focus on how these dietary changes may influence gut microbiome structure and overall health outcomes. Participants will supply stool samples before and after receiving their diet data to measure any changes in eating behavior.

Who should consider this trial

Good fit: Ideal candidates include parents or legal guardians of infants under 12 months who can provide stool samples and understand English.

Not a fit: Patients with health conditions that could confound dietary interpretation or pose risks during the study may not benefit.

Why it matters

Potential benefit: If successful, this study could lead to improved dietary habits and health outcomes for participants.

How similar studies have performed: While the approach of returning diet data is innovative, similar studies have shown promise in influencing dietary behavior through feedback mechanisms.
