Official title
Interaction and Modulation of Salivary Proteins With Repeat Exposure to Polyphenols
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Participants will be chosen through an initial sensory test to find high and low-perceivers of astringency. Selected participants will drink a chocolate milk or milk substitute beverage for one week each with washout weeks in between. At the end of each week participants will taste and rate multiple beverages for their astringency and other sensory properties. Participants will provide saliva samples weekly for proteomic analysis and (potentially) analysis of polyphenols. Participants will also be asked to provide a 24 hour dietary recall once per week. Data will be analyzed to determine if there is a relationship between polyphenol exposure, astringency ratings, and salivary protein composition.
