Healthy Adult Males

The purpose of this research study is to identify biomarkers of whole grain (WG) corn intake following an acute exposure in a pharmacokinetic (how the body absorbs, processes, and gets rid of a substance or ingredient) feeding study. In this aim, we will conduct a randomized crossover acute pharmacokinetic study of corn. We will then use a targeted metabolomics approach to identify the exposure markers of corn intake, further develop analytical methods to study its pharmacokinetics, and build our in-house WG metabolite database, and an untargeted metabolomics approach to investigate postprandial biomarkers of corn intake. At the completion of this study, our expectation is that we will identify corn phytochemicals and its metabolites as objective biomarkers of total and individual WG corn that are commonly consumed by Americans.
