Assessing Gut Microbiota Mediated Health Outcomes of Whole Wheat & Its

Status Active, not recruiting

Clinical Trial Summary

This study will investigate the gut microbiota-mediated effects of whole wheat consumption on human health in adults with pre-diabetes. Participants will complete two phases of intervention in random order in which they will consume either whole wheat bread (4 servings) or white bread a day for two weeks prior to collecting specimens (stool, urine, and plasma/serum).

Clinical Trial Description

Accumulating clinical evidence suggests positive effects of whole grain on cardiometabolic risk. However, outcomes of controlled trials indicate that substantial interpersonal variation occurs in these studies with regard to glucose homeostasis, with some persons being unaffected and others experiencing glucose-lowering effects due to whole wheat bread consumption. Whole grain (whole wheat) contains bioactive phytochemicals in addition to its well-recognized fiber content, and these constituents have not received adequate study to inform dietary recommendations. The objective of this study is to investigate the glucose-lowering effects of whole wheat bread in persons with prediabetes using multi-omics platforms that can provide an understanding of the complex interactions among the gut microbiome, gut metabolome, host metabolome, and gut barrier function. The hypothesis is that gut microbial metabolism of whole wheat and its major bioactive components is a determining factor of human health benefits. This will be tested by conducting a randomized, controlled crossover trial in persons with pre-diabetes who follow a controlled diet containing whole wheat bread or white bread for 2-weeks. Outcomes are expected to significantly advance an understanding of personalized, gut microbiome-mediated approaches in individuals with pre-diabetes to help guide dietary recommendations of whole wheat intake. In addition, novel evidence that maps out the differential functions of diverse genus/species of microbiota to biotransform whole wheat nutrients into more bioactive metabolites are expected. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
