Biomarker-estimated Flavanol Intake in Davis (FID) (NCT06086145)
🩺 Plain-English Summary (8th-Grade Level)
Flavanols are compounds present in plants, including apples, berries, peaches, cocoa-derived products and certain beverages like tea. Following intake, they are absorbed and broken down into smaller compounds called 'metabolites'. Some of these metabolites are excreted in urine. In this study, we hope to collect urine and examine the metabolites to learn more about the types and amounts of flavanols that people are consuming as part of their usual diet.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (5 items) and avoid the listed exclusions (11 items).
