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.

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.
