Novel 13C Carotenoids for Absorption and Metabolism Studies in Humans
Summary
Tomatoes contain several compounds which may be beneficial for human health and prevention of disease, although this relationship is poorly understood and very controversial. This study uses a new technology to study the absorption and metabolism of three different compounds found in tomatoes. These compounds are called: phytoene, phytofluene, and lycopene. We hypothesize that by studying the absorption and metabolism of these compounds, we may be able to understand how the compounds may influence health and disease processes.
Eligibility Criteria

Exclusion Criteria:
