Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Fruits and vegetables are an important source of many different phytochemicals that may affect health and accurate dietary assessement tools to quantitate dietary intake are essential. This study will evaluate the correlation of dietary carotenoid intake estimated from two common and one novel food frequency questionnaire (FFQ) with estimated carotenoid intake from 3 day diet records as well as measured blood and skin concentrations of carotenoids. This study will be conducted in healthy adults. These tools may be effective in estimating the level of these compounds in an average diet.
