Summary

This study tests how well three different food frequency questionnaires estimate how many fruits and vegetables people eat. Researchers will compare the questionnaire results to actual diet records and blood and skin tests for carotenoids—natural pigments found in plants. The goal is to find a simple, accurate tool for measuring dietary intake in healthy adults.
