About this study

Official title: Effect of Normal Dietary Intake and Medium Chain Triglycerides Supplementation on the Human Microbiome

The human gut microbiome is the community of bacteria that reside within the human intestine. These microbes are constantly exposed to the end-products and partial break-down-products of digestion from the foods consumed each day. Very little is known about the complex interaction of specific dietary components with the microbiome over time in one individual. In order to produce robust analysis of these interactions, longitudinal samples with detailed dietary intake information from healthy human subjects are needed.

The complex relationship between dietary intake and the microbiome, and the potential health implications of human exposure to microbial metabolites, are only beginning to be understood. It is well known that altered dietary intake can trigger rapid, although transient, changes in the composition of the microbiome in as little as 1 to 2 days. The biggest factors in determining microbial response to diet are thought to include an individual's starting microbiome, long-term dietary habits, and environmental exposures.

It is not well understood how small dietary differences from day-to-day impact the microbiome. A longitudinal dataset with accurately recorded dietary data and multiple samples over 17 days will provide valuable insight into the changes that occur at the individual level over time, while controlling for dietary trends and initial microbiome composition.

Medium chain triglycerides (MCTs) have systemic beneficial effects and increase survival in rats by preventing gut injury and permeability following lipopolysaccharide administration, preventing alcohol-induced liver injury, and protecting against the development of colitis in a model of Crohn's disease. Understanding the interaction of MCTs with the microbiome in humans could lead to important advancements in the understanding of how diet impacts the microbiome composition, and ultimately, human health. This proposed study is designed to evaluate the effect of MCTs compared with long chain triglycerides on the normal structure of the microbiome and data will not be used to diagnose, prevent, cure or treat disease.

The purpose of this study is to: 1) investigate the role daily dietary variation plays in microbiome composition and stability, and 2) explore the effect of MCT supplementation on microbiome composition in healthy adults.

Questions about this trial

What is this clinical trial studying?

A study testing Medium chain triglycerides and Long chain triglycerides in people with Healthy, run by University of Minnesota at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Microbiome composition (time frame: Change from baseline daily for 17 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03610477, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2019; AzTrials last refreshed its copy on 31 Oct 2026.
