Overview
Brief Summary
The investigators propose a comprehensive, multiomic study that will integrate longitudinal data associating changes in specific gut bacteria and host in response to prebiotic fiber supplementation. These data will guide the development of an integrative biological signature relating bacterial-derived metabolites with biological outcome in the host.
Detailed Description
With this study, the investigators propose to assemble a cohort of healthy individuals that will receive prebiotic supplementation, during comprehensive, longitudinal characterization of the microbiota and host changes with clinical markers and multiple omics assays. These multiomic data will then be integrated, generating unique biological signatures that define the role that microbial metabolites from specific bacteria play in host biological activity. Through this study the investigators expect to gain a detailed and clear understanding of the physiological changes, at the mechanistic level, that occur in the microbiome and host in response to dietary supplementation with prebiotic fiber.

Outcomes
Primary Outcomes
Mapping of microbiota changes in response to prebiotic intervention
Time Frame: 3 years
A detailed map of microbes and microbial gene expression changes during the intervention will be developed. Microbiota complexity in fecal samples will be determined by shotgun metagenomic sequencing. Novel microbes and gene pathways will be identified by de novo assemble of whole fecal metagenomes.
Lipid profile changes in response to prebiotic intervention
Time Frame: 3 years
Analysis of changes in the the lipid profile of participants on the prebiotic intervention. Measured lipids in mg/dL include total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides.
Secondary Outcomes
- Comprehensive cytokine profile during prebiotic intervention(3 years)
- Comprehensive transcriptome profile during prebiotic intervention(3 years)
- Comprehensive metabolome profile during prebiotic intervention(3 years)
- Comprehensive metagenome profile during prebiotic intervention(3 years)
