Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

The purpose with this project is to study the association between bacterial fermentation in the colon of specific mixtures of cereal dietary fiber and effects on systemic metabolism and appetite regulation. For this purpose, short term studies are performed in healthy adult subjects. Different cereals, cereal blends and from cereal extracted dietary fiber will be studied, as well as effects of different processing of the cereals. Cardiometabolic test markers and colonic fermentation metabolites will be followed up to 14 h after intake of the test substrates, and gut microbiota composition will be determined prior to and after the interventions.

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.
