High Fructose Diet, the Gut Microbiome, and Metabolic Health
NCT06329544 · View on ClinicalTrials.gov ↗
Study Summary
Americans commonly consume excess amounts of dietary fructose. Added fructose has been shown to have an adverse impact on metabolic health, including increased insulin resistance and type 2 diabetes (T2D) risk. However, the mechanisms that link dietary fructose and metabolic health are poorly understood. Malabsorption or incomplete metabolism of fructose in the small intestine is common in the population. Excess fructose reaches the colon where it may change the structure and function of the gut microbiome, alter bacterial metabolites and trigger inflammatory responses impacting T2D risk. To elucidate whether commonly consumed levels of dietary fructose influence metabolic outcomes through altering the gut microbiome, the research team will randomize 30 participants to a controlled cross-over dietary intervention, in which the participants will consume 12-day isocaloric, added fructose or glucose diets (25% of total calories) separated by a 10-day controlled diet washout period. The research team aims to: 1. Determine the relationships between high fructose consumption, the gut microbiome and metabolic risk. 2. Characterize the causal role(s) that fructose-induced alterations to the gut microbiome have on metabolic risk using a germ-free mouse model. The research team will measure 1) microbiota community structure and function via metagenomic sequencing of stool, 2) fecal metabolites via targeted and untargeted metabolomics, 3) anthropometrics, 4) insulin resistance, serum markers of T2D risk and inflammatory cytokines, 5) fecal microbial carbohydrate oxidation capacity and 6) liver fat via MRI elastography. The research team will use novel statistical approaches, including Distributed Lag Modeling, to understand the complex relationships between diet, the microbiome, metabolites and health outcomes. The research team will then conduct controlled dietary interventions and fecal microbiome transplantation studies in germ-free mice. Donor fecal samples from human

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06329544
The ClinicalTrials.gov registry entry for NCT06329544 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 30 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Icahn School of Medicine at Mount Sinai, which has 946 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Obesity appearing as the primary indexed condition, and to 2 interventions — of which Fructose is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06329544 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
