Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 65 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

The disease, disorder, syndrome, illness, or injury that is being studied.
The inflammatory bowel disease (IBD) subtype, Crohn's disease (CD) is a chronic and relapsing inflammatory disorder of the gastrointestinal tract. Although the precise etiology of IBD is not known, evidence suggests that environmental factors, including diet, contribute to its pathogenesis. A soy-based diet has been demonstrated to have numerous health benefits. This single-center open-label study will compare the effectiveness of a soy-based diet or an identical diet without soy to change the gut microbiota composition and fecal butyrate concentration to that of baseline (pre-diet) in patients with CD (remission or active disease) and healthy control subjects without CD. Participants will follow either a soy-based diet or an identical diet without soy to which they will be randomized for 7 days. No data collection or other study procedures will take place until the potential participant provides written informed consent to participate in the research study. The informed consent, screening, enrollment, and baseline data collection which make up visit 1 can occur on the same day or be completed across several days.
Experimental: Soy-based diet
Participants will be randomized to follow a soy-based diet for 7 days. The diet will be preceded by a 12-hr overnight fast.
Active Comparator: Regular diet
Participants will be randomized to follow a diet without soy for 7 days. The diet will be preceded by a 12-hr overnight fast.
Other: - Soy based diet
The diet will be based on the detailed descriptions according to the American Heart Association, US Food and Drug Administration (FDA), and the Soyfoods Association of North America Website, which all promote soy products as having beneficial nutrient profiles with a daily consumption of 25 grams or more of soy protein (average serving = 6.25 grams), upper limit of 50g.
Other: - Non-soy based diet
Diet of identical composition to the soy diet with the exception of soy.
