Summary

This study aims to investigate the impact of various healthy diets, specifically a modified plant-based Mediterranean diet, on the gut microbiome and overall well-being post-colonoscopy. The investigators hypothesize that certain diets can positively influence gut bacteria, reducing inflammation and enhancing metabolic signals.

To explore this, they will utilize metagenomic testing on stool samples to analyze the DNA of gut microorganisms. Additionally, they will conduct immune profiling on serum samples and perform metabolomic analysis to comprehensively evaluate the diet-induced changes in immune response and metabolic pathways. This multi-faceted approach will help them understand how dietary changes affect the composition and function of the gut microbiome, immune function, and overall metabolism.

Interventions

DIETARY_SUPPLEMENT

Modified Plant-Based Mediterranean Diet

Two-week dietary intervention after the participants' scheduled colonoscopy consisting of vegetarian high-fiber meals. These meals are designed to provide a substantial intake of dietary fiber through a variety of plant-based foods, including whole grains, legumes, fruits, vegetables, nuts, and seeds. Meals will be delivered bi-weekly, and compliance will be monitored through regular check-ins with a study dietitian.
