Spices for Cultivating a Healthy Gut Microbiome and Cardiometabolic Profile

March 18, 2024 updated by: University of Alabama, Tuscaloosa

Spices for Cultivating a Healthy Gut Microbiome and Cardiometabolic Profile: the SPICE Study

Among food products receiving attention for prebiotic functionality, spices represent a flavorful vehicle for cultivating a healthy gut microbiota. As the required doses of spice-derived polyphenols to elicit prebiotic and systemic metabolic effects are not well-characterized, additional research is warranted. Thus, the investigators propose to use a food-first synbiotic (prebiotic + probiotic) approach to examine alterations in the gut microbiota pre- and post-intervention/placebo and their relationship with systemic cardiometabolic effects mediated by short chain fatty acids (SCFA) and gut-derived metabolites.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study will be conducted as a single blind, randomized crossover design with a 4-week arm (placebo or control) followed by a 2-week washout period and another 4-week arm (placebo or control).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes
