Biomarker-estimated Flavanol Intake in Davis (FID)

Flavanol Intake in Davis (FID) Study: Biomarker-estimated Habitual (-)-Epicatechin and Flavanol Intake in Adults

Sponsor

University of California, Davis

Enrollment

200 participants

Start Date

Nov 2, 2023

Study Type

OBSERVATIONAL

Conditions

Healthy Diet Adults

Summary

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.
