Summary

This study looks at flavanols, natural compounds found in foods like apples, berries, and tea. Researchers will collect urine samples from 200 healthy adults to measure flavanol metabolites and estimate how much flavanols people typically consume. The goal is to better understand dietary intake patterns, not to test a treatment.
