Racial differences in correlations between reported dietary intakes of carotenoids and their concentration biomarkers.

ABSTRACT:

Background

The predictive ability of dietary assessment methods to estimate specific circulating plasma carotenoid concentrations has been compared between African Americans and whites in only one study to date.

Objective

The predictive abilities of 24-h dietary recalls and a food-frequency questionnaire in reporting dietary carotenoids when measured against concentration biomarkers were assessed in African Americans and compared with the findings in whites.

Design

Data were collected from 250 generally healthy, nonsmoking white and African American participants aged 21-69 y, who completed 8 self-administered online 24-h dietary recalls and one National Cancer Institute diet-history questionnaire in the University of California Los Angeles (UCLA) Energetics Study.
